#how to set up a localhost

[heart-ghost-studyblr]

This one has an interesting story. It was in a place where we shared files through a shared data server locally (localhost only), so there was no network access to use the famous "I love PDF" or software like Adobe to convert and make some changes.

With that in mind, I used the PyPDF library to make a code that changes like converting, splitting, merging, and set it up on the server for people to use. Everyone loved both how the program worked and the crazy aesthetic that I made it and my boss approved. Well, problem solved! And fun too, I must say. And since this is a Studyblr, I have to mention how worthwhile it is to study a library you've never seen before but that seems to do everything you need at that moment. Putting a small project into practice, seeing how people react to it, then studying and improving it in a way that reflects your own growth. That was made with Django Web Framework.

Obsidian And RTX AI PCs For Advanced Large Language Model

How to Utilize Obsidian‘s Generative AI Tools. Two plug-ins created by the community demonstrate how RTX AI PCs can support large language models for the next generation of app developers.

Obsidian Meaning

Obsidian is a note-taking and personal knowledge base program that works with Markdown files. Users may create internal linkages for notes using it, and they can see the relationships as a graph. It is intended to assist users in flexible, non-linearly structuring and organizing their ideas and information. Commercial licenses are available for purchase, however personal usage of the program is free.

Obsidian Features

Electron is the foundation of Obsidian. It is a cross-platform program that works on mobile operating systems like iOS and Android in addition to Windows, Linux, and macOS. The program does not have a web-based version. By installing plugins and themes, users may expand the functionality of Obsidian across all platforms by integrating it with other tools or adding new capabilities.

Obsidian distinguishes between community plugins, which are submitted by users and made available as open-source software via GitHub, and core plugins, which are made available and maintained by the Obsidian team. A calendar widget and a task board in the Kanban style are two examples of community plugins. The software comes with more than 200 community-made themes.

Every new note in Obsidian creates a new text document, and all of the documents are searchable inside the app. Obsidian works with a folder of text documents. Obsidian generates an interactive graph that illustrates the connections between notes and permits internal connectivity between notes. While Markdown is used to accomplish text formatting in Obsidian, Obsidian offers quick previewing of produced content.

Generative AI Tools In Obsidian

A group of AI aficionados is exploring with methods to incorporate the potent technology into standard productivity practices as generative AI develops and speeds up industry.

Community plug-in-supporting applications empower users to investigate the ways in which large language models (LLMs) might improve a range of activities. Users using RTX AI PCs may easily incorporate local LLMs by employing local inference servers that are powered by the NVIDIA RTX-accelerated llama.cpp software library.

It previously examined how consumers might maximize their online surfing experience by using Leo AI in the Brave web browser. Today, it examine Obsidian, a well-known writing and note-taking tool that uses the Markdown markup language and is helpful for managing intricate and connected records for many projects. Several of the community-developed plug-ins that add functionality to the app allow users to connect Obsidian to a local inferencing server, such as LM Studio or Ollama.

To connect Obsidian to LM Studio, just select the “Developer” button on the left panel, load any downloaded model, enable the CORS toggle, and click “Start.” This will enable LM Studio’s local server capabilities. Because the plug-ins will need this information to connect, make a note of the chat completion URL from the “Developer” log console (“http://localhost:1234/v1/chat/completions” by default).

Next, visit the “Settings” tab after launching Obsidian. After selecting “Community plug-ins,” choose “Browse.” Although there are a number of LLM-related community plug-ins, Text Generator and Smart Connections are two well-liked choices.

For creating notes and summaries on a study subject, for example, Text Generator is useful in an Obsidian vault.

Asking queries about the contents of an Obsidian vault, such the solution to a trivia question that was stored years ago, is made easier using Smart Connections.

Open the Text Generator settings, choose “Custom” under “Provider profile,” and then enter the whole URL in the “Endpoint” section. After turning on the plug-in, adjust the settings for Smart Connections. For the model platform, choose “Custom Local (OpenAI Format)” from the options panel on the right side of the screen. Next, as they appear in LM Studio, type the model name (for example, “gemma-2-27b-instruct”) and the URL into the corresponding fields.

The plug-ins will work when the fields are completed. If users are interested in what’s going on on the local server side, the LM Studio user interface will also display recorded activities.

Transforming Workflows With Obsidian AI Plug-Ins

Consider a scenario where a user want to organize a trip to the made-up city of Lunar City and come up with suggestions for things to do there. “What to Do in Lunar City” would be the title of the new note that the user would begin. A few more instructions must be included in the query submitted to the LLM in order to direct the results, since Lunar City is not an actual location. The model will create a list of things to do while traveling if you click the Text Generator plug-in button.

Obsidian will ask LM Studio to provide a response using the Text Generator plug-in, and LM Studio will then execute the Gemma 2 27B model. The model can rapidly provide a list of tasks if the user’s machine has RTX GPU acceleration.

Or let’s say that years later, the user’s buddy is visiting Lunar City and is looking for a place to dine. Although the user may not be able to recall the names of the restaurants they visited, they can review the notes in their vault Obsidian‘s word for a collection of notes to see whether they have any written notes.

A user may ask inquiries about their vault of notes and other material using the Smart Connections plug-in instead of going through all of the notes by hand. In order to help with the process, the plug-in retrieves pertinent information from the user’s notes and responds to the request using the same LM Studio server. The plug-in uses a method known as retrieval-augmented generation to do this.

Although these are entertaining examples, users may see the true advantages and enhancements in daily productivity after experimenting with these features for a while. Two examples of how community developers and AI fans are using AI to enhance their PC experiences are Obsidian plug-ins.

Thousands of open-source models are available for developers to include into their Windows programs using NVIDIA GeForce RTX technology.

Ansible Collections: Extending Ansible’s Capabilities

Ansible is a powerful automation tool used for configuration management, application deployment, and task automation. One of the key features that enhances its flexibility and extensibility is the concept of Ansible Collections. In this blog post, we'll explore what Ansible Collections are, how to create and use them, and look at some popular collections and their use cases.

Introduction to Ansible Collections

Ansible Collections are a way to package and distribute Ansible content. This content can include playbooks, roles, modules, plugins, and more. Collections allow users to organize their Ansible content and share it more easily, making it simpler to maintain and reuse.

Key Features of Ansible Collections:

Modularity: Collections break down Ansible content into modular components that can be independently developed, tested, and maintained.

Distribution: Collections can be distributed via Ansible Galaxy or private repositories, enabling easy sharing within teams or the wider Ansible community.

Versioning: Collections support versioning, allowing users to specify and depend on specific versions of a collection. How to Create and Use Collections in Your Projects

Creating and using Ansible Collections involves a few key steps. Here’s a guide to get you started:

1. Setting Up Your Collection

To create a new collection, you can use the ansible-galaxy command-line tool:

ansible-galaxy collection init my_namespace.my_collection

This command sets up a basic directory structure for your collection:

my_namespace/

└── my_collection/

├── docs/

├── plugins/

│ ├── modules/

│ ├── inventory/

│ └── ...

├── roles/

├── playbooks/

├── README.md

└── galaxy.yml

2. Adding Content to Your Collection

Populate your collection with the necessary content. For example, you can add roles, modules, and plugins under the respective directories. Update the galaxy.yml file with metadata about your collection.

3. Building and Publishing Your Collection

Once your collection is ready, you can build it using the following command:

ansible-galaxy collection build

This command creates a tarball of your collection, which you can then publish to Ansible Galaxy or a private repository:

ansible-galaxy collection publish my_namespace-my_collection-1.0.0.tar.gz

4. Using Collections in Your Projects

To use a collection in your Ansible project, specify it in your requirements.yml file:

collections:

- name: my_namespace.my_collection

version: 1.0.0

Then, install the collection using:

ansible-galaxy collection install -r requirements.yml

You can now use the content from the collection in your playbooks:--- - name: Example Playbook hosts: localhost tasks: - name: Use a module from the collection my_namespace.my_collection.my_module: param: value

Popular Collections and Their Use Cases

Here are some popular Ansible Collections and how they can be used:

1. community.general

Description: A collection of modules, plugins, and roles that are not tied to any specific provider or technology.

Use Cases: General-purpose tasks like file manipulation, network configuration, and user management.

2. amazon.aws

Description: Provides modules and plugins for managing AWS resources.

Use Cases: Automating AWS infrastructure, such as EC2 instances, S3 buckets, and RDS databases.

3. ansible.posix

Description: A collection of modules for managing POSIX systems.

Use Cases: Tasks specific to Unix-like systems, such as managing users, groups, and file systems.

4. cisco.ios

Description: Contains modules and plugins for automating Cisco IOS devices.

Use Cases: Network automation for Cisco routers and switches, including configuration management and backup.

5. kubernetes.core

Description: Provides modules for managing Kubernetes resources.

Use Cases: Deploying and managing Kubernetes applications, services, and configurations.

Conclusion

Ansible Collections significantly enhance the modularity, distribution, and reusability of Ansible content. By understanding how to create and use collections, you can streamline your automation workflows and share your work with others more effectively. Explore popular collections to leverage existing solutions and extend Ansible’s capabilities in your projects.

[full-stack1]

Certainly! Let’s explore how to build a full-stack application using Node.js. In this comprehensive guide, we’ll cover the essential components and steps involved in creating a full-stack web application.

Building a Full-Stack Application with Node.js, Express, and MongoDB

1. Node.js: The Backbone of Our Application

Node.js is a runtime environment that allows us to run JavaScript on the server-side.

It’s built on Chrome’s V8 JavaScript engine and uses an event-driven, non-blocking I/O model, making it lightweight and efficient.

Node.js serves as the backbone of our application, providing the environment in which our server-side code will run.

2. Express.js: Simplifying Server-Side Development

Express.js is a minimal and flexible Node.js web application framework.

It provides a robust set of features for building web and mobile applications.

With Express.js, we can:

Set up middlewares to respond to HTTP requests.

Define routing rules.

Add additional features like template engines.

3. MongoDB: Storing Our Data

MongoDB is a document-oriented database program.

It uses JSON-like documents with optional schemas and is known for its flexibility and scalability.

We’ll use MongoDB to store our application’s data in an accessible and writable format.

Building Our Full-Stack Application: A Step-by-Step Guide

Setting Up the Environment:

Install Node.js:sudo apt install nodejs

Initialize a new Node.js project:mkdir myapp && cd myapp npm init -y

Install Express.js:npm install express

Creating the Server:

Create a basic Express server:const express = require('express'); const app = express(); const port = 3000; app.get('/', (req, res) => { res.send('Hello World!'); }); app.listen(port, () => { console.log(`Server running at http://localhost:${port}`); });

Defining Routes:

Define routes for different parts of our application:app.get('/user', (req, res) => { res.send('User Page'); });

Connecting to MongoDB:

Use Mongoose (a MongoDB object modeling tool) to connect to MongoDB and handle data storage.

Remember, this is just the beginning! Full-stack development involves frontend (client-side) work as well. You can use React, Angular, or other frontend libraries to build the user interface and connect it to your backend (Node.js and Express).

Feel free to explore more about each component and dive deeper into building your full-stack application! 😊 12

How To Setup Elasticsearch 6.4 On RHEL/CentOS 6/7?

What is Elasticsearch? Elasticsearch is a search engine based on Lucene. It is useful in a distributed environment and helps in a multitenant-capable full-text search engine. While you query something from Elasticsearch it will provide you with an HTTP web interface and schema-free JSON documents. it provides the ability for full-text search. Elasticsearch is developed in Java and is released as open-source under the terms of the Apache 2 license. Scenario: 1. Server IP: 192.168.56.101 2. Elasticsearch: Version 6.4 3. OS: CentOS 7.5 4. RAM: 4 GB Note: If you are a SUDO user then prefix every command with sudo, like #sudo ifconfig With the help of this guide, you will be able to set up Elasticsearch single-node clusters on CentOS, Red Hat, and Fedora systems. Step 1: Install and Verify Java Java is the primary requirement for installing Elasticsearch. So, make sure you have Java installed on your system. # java -version openjdk version "1.8.0_181" OpenJDK Runtime Environment (build 1.8.0_181-b13) OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode) If you don’t have Java installed on your system, then run the below command # yum install java-1.8.0-openjdk Step 2: Setup Elasticsearch For this guide, I am downloading the latest Elasticsearch tar from its official website so follow the below step # wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # tar -xzf elasticsearch-6.4.2.tar.gz # mv elasticsearch-6.4.2 /usr/local/elasticsearch Step 5: Permission and User We need a user for running elasticsearch (root is not recommended). # useradd elasticsearch # chown -R elasticsearch.elasticsearch /usr/local/elasticsearch/ Step 6: Setup Ulimits Now to get a Running system we need to make some changes of ulimits else we will get an error like “max number of threads for user is too low, increase to at least ” so to overcome this issue make below changes you should run. # ulimit -n 65536 # ulimit -u 2048 Or you may edit the file to make changes permanent # vim /etc/security/limits.conf elasticsearch - nofile 65536 elasticsearch soft nofile 64000 elasticsearch hard nofile 64000 elasticsearch hard nproc 4096 elasticsearch soft nproc 4096 Save files using :wq Step 7: Configure Elasticsearch Now make some configuration changes like cluster name or node name to make our single node cluster live. # cd /usr/local/elasticsearch/ Now, look for the below keywords in the file and change according to you need # vim conf/elasticsearch.yml cluster.name: kapendra-cluster-1 node.name: kapendra-node-1 http.port: 9200 to set this value to your IP or make it 0.0.0.0 ID needs to be accessible from anywhere from the network. Else put your IP of localhost network.host: 0.0.0.0 There is one more thing if you have any dedicated mount pint for data then change the value for #path.data: /path/to/data to your mount point.

Your configuration should look like the above. Step 8: Starting Elasticsearch Cluster As the Elasticsearch setup is completed. Let the start Elasticsearch cluster with elastic search user so first switch to elastic search user and then run the cluster # su - elasticsearch $ /usr/local/elasticsearch/bin/elasticsearch 22278 Step 9: Verify Setup You have all done it, just need to verify the setup. Elasticsearch works on port default port 9200, open your browser to point your server on port 9200, You will find something like the below output http://localhost:9200 or http://192.168.56.101:9200 at the end of this article, you have successfully set up Elasticsearch single node cluster. In the next few articles, we will try to cover a few commands and their setup in the docker container for development environments on local machines. Read the full article

How to Integrate Newgrounds Medals with Construct 3 (PixelPerfect NewgroundsIO API Plugin Method)

After several attempts and a lot of troubleshooting, I’ve finally figured out how to successfully integrate NGIO plugin with Construct 3 to enable Newgrounds medals in my game. I’m writing this tutorial mainly for my own reference, so I’ll have a clear step-by-step guide the next time I want to integrate medals (or other Newgrounds features) into another project. Right now, this covers just the medal setup—when I try out things like scoreboards or cloud saves, I’ll come back and update this with anything important I learn.

1. Newgrounds Account and Project Setup

Register or log in at newgrounds.com.

Visit Newgrounds Projects.

Create a new project and fill in the required information.

Scroll all the way down to the footer navigation and click API Tools.

After agreeing to the API activation, click “I agree, show me the tools!” to access the Newgrounds.io dashboard.

In the dashboard, locate your App ID and Encryption Key (copy these for the plugin), as well as Medal/Scoreboard/Cloud Save setup and other API tools.

Create medals on the Newgrounds project page. After creating each one, note its numeric ID for use in the plugin.

2. Downloading the Plugin

Download the Newgrounds.io plugin from Pixel Perfect Studio.

In Construct 3, go to Menu → Addons → Import Addon, then select the downloaded file.

Add a Newgrounds.io object to your project layout.

When exporting for publishing, ensure the entire exported folder (with all files and plugins) is uploaded to Newgrounds.

3. Setting Up the Construct 3 Project and Plugin Details

Start a new Construct 3 project (or use an existing one).

Check project properties such as viewport size, layout order, and loader style.

Select the Newgrounds.io object in your layout, then enter the App ID and Encryption Key exactly as shown in your Newgrounds API Tools page (no extra spaces or characters).

Set up an event to trigger NGIO login after player input (for example, “Press Any Key” on an intro/title screen). Login should not be called on “Start of Layout,” as browsers may block popups unless triggered by user action.

To unlock a medal during gameplay (such as on player death), use the plugin’s “Unlock medal” action and enter only the numeric Medal ID (not “ID#”).

4. Dos and Don’ts for Publishing the Project

Always export as “HTML5 Website” and upload every file to Newgrounds.

In export options, set Minify Mode to Simple. Using “Advanced” minification can break plugin code and prevent medals or NGIO features from working.

Double-check App ID and AES key for typos—these must match exactly or API communication will fail.

Test only on Newgrounds.com (not localhost or other hosts); medals and login require correct domain and project configuration.

Ignore the “Apps with Access” section unless specifically sharing medals or leaderboards between multiple App IDs or projects.

Start Coding Today: Learn React JS for Beginners

Start Coding Today: Learn React JS for Beginners”—will give you a solid foundation and guide you step by step toward becoming a confident React developer.

React JS, developed by Facebook, is an open-source JavaScript library used to build user interfaces, especially for single-page applications (SPAs). Unlike traditional JavaScript or jQuery, React follows a component-based architecture, making the code easier to manage, scale, and debug. With React, you can break complex UIs into small, reusable pieces called components.

Why Learn React JS?

Before diving into the how-to, let’s understand why learning React JS is a smart choice for beginners:

High Demand: React developers are in high demand in tech companies worldwide.

Easy to Learn: If you know basic HTML, CSS, and JavaScript, you can quickly get started with React.

Reusable Components: Build and reuse UI blocks easily across your project.

Strong Community Support: Tons of tutorials, open-source tools, and documentation are available.

Backed by Facebook: React is regularly updated and widely used in real-world applications (Facebook, Instagram, Netflix, Airbnb).

Prerequisites Before You Start

React is based on JavaScript, so a beginner should have:

Basic knowledge of HTML and CSS

Familiarity with JavaScript fundamentals such as variables, functions, arrays, and objects

Understanding of ES6+ features like let, const, arrow functions, destructuring, and modules

Don’t worry if you’re not perfect at JavaScript yet. You can still start learning React and improve your skills as you go.

Setting Up the React Development Environment

There are a few ways to set up your React project, but the easiest way for beginners is using Create React App, a boilerplate provided by the React team.

Step 1: Install Node.js and npm

Download and install Node.js from https://nodejs.org. npm (Node Package Manager) comes bundled with it.

Step 2: Install Create React App

Open your terminal or command prompt and run:

create-react-app my-first-react-app

This command creates a new folder with all the necessary files and dependencies.

Step 3: Start the Development Server

Navigate to your app folder:

my-first-react-app

Then start the app:

Your first React application will launch in your browser at http://localhost:3000.

Understanding the Basics of React

Now that you have your environment set up, let’s understand key React concepts:

1. Components

React apps are made up of components. Each component is a JavaScript function or class that returns HTML (JSX).

function Welcome() { return <h1>Hello, React Beginner!</h1>; }

2. JSX (JavaScript XML)

JSX lets you write HTML inside JavaScript. It’s not mandatory, but it makes code easier to write and understand.

const element = <h1>Hello, World!</h1>;

3. Props

Props (short for properties) allow you to pass data from one component to another.

function Welcome(props) { return <h1>Hello, {props.name}</h1>; }

4. State

State lets you track and manage data within a component.

import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ( <div> <p>You clicked {count} times.</p> <button onClick={() => setCount(count + 1)}>Click me</button> </div> ); }

Building Your First React App

Let’s create a simple React app — a counter.

Open the App.js file.

Replace the existing code with the following:

import React, { useState } from 'react'; function App() { const [count, setCount] = useState(0); return ( <div style={{ textAlign: 'center', marginTop: '50px' }}> <h1>Simple Counter App</h1> <p>You clicked {count} times</p> <button onClick={() => setCount(count + 1)}>Click Me</button> </div> ); } export default App;

Save the file, and see your app live on the browser.

Congratulations—you’ve just built your first interactive React app!

Where to Go Next?

After mastering the basics, explore the following:

React Router: For navigation between pages

useEffect Hook: For side effects like API calls

Forms and Input Handling

API Integration using fetch or axios

Styling (CSS Modules, Styled Components, Tailwind CSS)

Context API or Redux for state management

Deploying your app on platforms like Netlify or Vercel

Practice Projects for Beginners

Here are some simple projects to strengthen your skills:

Todo App

Weather App using an API

Digital Clock

Calculator

Random Quote Generator

These will help you apply the concepts you've learned and build your portfolio.

Final Thoughts

This “Start Coding Today: Learn React JS for Beginners” guide is your entry point into the world of modern web development. React is beginner-friendly yet powerful enough to build complex applications. With practice, patience, and curiosity, you'll move from writing your first “Hello, World!” to deploying full-featured web apps.

Remember, the best way to learn is by doing. Start small, build projects, read documentation, and keep experimenting. The world of React is vast and exciting—start coding today, and you’ll be amazed by what you can create!

Backend Web Development Using Node.js

Node.js has revolutionized web development by enabling developers to write server-side code using JavaScript. If you're already comfortable with JavaScript on the frontend, transitioning to backend development with Node.js is a logical next step. In this post, we'll introduce the fundamentals of backend development using Node.js and how to build scalable, efficient web applications.

What is Node.js?

Node.js is a JavaScript runtime built on Chrome’s V8 engine. It allows developers to use JavaScript to write backend code, run scripts outside the browser, and build powerful network applications. Node.js is known for its non-blocking, event-driven architecture, making it highly efficient for I/O-heavy applications.

Why Use Node.js for Backend Development?

JavaScript Everywhere: Use a single language for both frontend and backend.

Asynchronous and Non-blocking: Great for handling many connections at once.

Vast Ecosystem: Thousands of modules available via npm (Node Package Manager).

Scalability: Ideal for microservices and real-time applications like chats or games.

Setting Up a Node.js Project

Install Node.js from nodejs.org

Create a new project folder:

Initialize the project:

Create your main file:

Basic Server Example

const http = require('http'); const server = http.createServer((req, res) => { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello, Node.js Backend!'); }); server.listen(3000, () => { console.log('Server running on http://localhost:3000'); });

Using Express.js for Easier Development

Express.js is a popular web framework for Node.js that simplifies routing and middleware management.npm install express const express = require('express'); const app = express(); app.get('/', (req, res) => { res.send('Welcome to the Node.js backend!'); }); app.listen(3000, () => { console.log('Express server running on http://localhost:3000'); });

Common Backend Tasks with Node.js

Handle routing and API endpoints

Connect to databases (MongoDB, PostgreSQL, etc.)

Manage user authentication and sessions

Process form data and JSON

Serve static files

Popular Libraries and Tools

Express.js: Web framework

Mongoose: MongoDB object modeling

dotenv: Environment variable management

JWT: JSON Web Tokens for authentication

Nodemon: Auto-restart server on code changes

Best Practices

Use environment variables for sensitive data

Structure your project using MVC or service-based architecture

Use middleware for error handling and logging

Validate and sanitize user input

Secure your APIs with authentication and rate-limiting

Conclusion

Node.js is a powerful and flexible choice for backend development. Its ability to use JavaScript on the server-side, combined with a rich ecosystem of libraries, makes it ideal for building modern web applications. Start small, experiment with Express, and gradually add more features to build robust backend services.

Automated Visual Regression Testing With Playwright

New Post has been published on https://thedigitalinsider.com/automated-visual-regression-testing-with-playwright/

Automated Visual Regression Testing With Playwright

Comparing visual artifacts can be a powerful, if fickle, approach to automated testing. Playwright makes this seem simple for websites, but the details might take a little finessing.

Recent downtime prompted me to scratch an itch that had been plaguing me for a while: The style sheet of a website I maintain has grown just a little unwieldy as we’ve been adding code while exploring new features. Now that we have a better idea of the requirements, it’s time for internal CSS refactoring to pay down some of our technical debt, taking advantage of modern CSS features (like using CSS nesting for more obvious structure). More importantly, a cleaner foundation should make it easier to introduce that dark mode feature we’re sorely lacking so we can finally respect users’ preferred color scheme.

However, being of the apprehensive persuasion, I was reluctant to make large changes for fear of unwittingly introducing bugs. I needed something to guard against visual regressions while refactoring — except that means snapshot testing, which is notoriously slow and brittle.

In this context, snapshot testing means taking screenshots to establish a reliable baseline against which we can compare future results. As we’ll see, those artifacts are influenced by a multitude of factors that might not always be fully controllable (e.g. timing, variable hardware resources, or randomized content). We also have to maintain state between test runs, i.e. save those screenshots, which complicates the setup and means our test code alone doesn’t fully describe expectations.

Having procrastinated without a more agreeable solution revealing itself, I finally set out to create what I assumed would be a quick spike. After all, this wouldn’t be part of the regular test suite; just a one-off utility for this particular refactoring task.

Fortunately, I had vague recollections of past research and quickly rediscovered Playwright’s built-in visual comparison feature. Because I try to select dependencies carefully, I was glad to see that Playwright seems not to rely on many external packages.

Setup

The recommended setup with npm init playwright@latest does a decent job, but my minimalist taste had me set everything up from scratch instead. This do-it-yourself approach also helped me understand how the different pieces fit together.

Given that I expect snapshot testing to only be used on rare occasions, I wanted to isolate everything in a dedicated subdirectory, called test/visual; that will be our working directory from here on out. We’ll start with package.json to declare our dependencies, adding a few helper scripts (spoiler!) while we’re at it:

"scripts": "test": "playwright test", "report": "playwright show-report", "update": "playwright test --update-snapshots", "reset": "rm -r ./playwright-report ./test-results ./viz.test.js-snapshots , "devDependencies": "@playwright/test": "^1.49.1"

If you don’t want node_modules hidden in some subdirectory but also don’t want to burden the root project with this rarely-used dependency, you might resort to manually invoking npm install --no-save @playwright/test in the root directory when needed.

With that in place, npm install downloads Playwright. Afterwards, npx playwright install downloads a range of headless browsers. (We’ll use npm here, but you might prefer a different package manager and task runner.)

We define our test environment via playwright.config.js with about a dozen basic Playwright settings:

import defineConfig, devices from "@playwright/test"; let BROWSERS = ["Desktop Firefox", "Desktop Chrome", "Desktop Safari"]; let BASE_URL = "http://localhost:8000"; let SERVER = "cd ../../dist && python3 -m http.server"; let IS_CI = !!process.env.CI; export default defineConfig( testDir: "./", fullyParallel: true, forbidOnly: IS_CI, retries: 2, workers: IS_CI ? 1 : undefined, reporter: "html", webServer: command: SERVER, url: BASE_URL, reuseExistingServer: !IS_CI , use: baseURL: BASE_URL, trace: "on-first-retry" , projects: BROWSERS.map(ua => ( name: ua.toLowerCase().replaceAll(" ", "-"), use: ...devices[ua] )) );

Here we expect our static website to already reside within the root directory’s dist folder and to be served at localhost:8000 (see SERVER; I prefer Python there because it’s widely available). I’ve included multiple browsers for illustration purposes. Still, we might reduce that number to speed things up (thus our simple BROWSERS list, which we then map to Playwright’s more elaborate projects data structure). Similarly, continuous integration is YAGNI for my particular scenario, so that whole IS_CI dance could be discarded.

Capture and compare

Let’s turn to the actual tests, starting with a minimal sample.test.js file:

import test, expect from "@playwright/test"; test("home page", async ( page ) => await page.goto("/"); await expect(page).toHaveScreenshot(); );

npm test executes this little test suite (based on file-name conventions). The initial run always fails because it first needs to create baseline snapshots against which subsequent runs compare their results. Invoking npm test once more should report a passing test.

Changing our site, e.g. by recklessly messing with build artifacts in dist, should make the test fail again. Such failures will offer various options to compare expected and actual visuals:

We can also inspect those baseline snapshots directly: Playwright creates a folder for screenshots named after the test file (sample.test.js-snapshots in this case), with file names derived from the respective test’s title (e.g. home-page-desktop-firefox.png).

Generating tests

Getting back to our original motivation, what we want is a test for every page. Instead of arduously writing and maintaining repetitive tests, we’ll create a simple web crawler for our website and have tests generated automatically; one for each URL we’ve identified.

Playwright’s global setup enables us to perform preparatory work before test discovery begins: Determine those URLs and write them to a file. Afterward, we can dynamically generate our tests at runtime.

While there are other ways to pass data between the setup and test-discovery phases, having a file on disk makes it easy to modify the list of URLs before test runs (e.g. temporarily ignoring irrelevant pages).

Site map

The first step is to extend playwright.config.js by inserting globalSetup and exporting two of our configuration values:

export let BROWSERS = ["Desktop Firefox", "Desktop Chrome", "Desktop Safari"]; export let BASE_URL = "http://localhost:8000"; // etc. export default defineConfig( // etc. globalSetup: require.resolve("./setup.js") );

Although we’re using ES modules here, we can still rely on CommonJS-specific APIs like require.resolve and __dirname. It appears there’s some Babel transpilation happening in the background, so what’s actually being executed is probably CommonJS? Such nuances sometimes confuse me because it isn’t always obvious what’s being executed where.

We can now reuse those exported values within a newly created setup.js, which spins up a headless browser to crawl our site (just because that’s easier here than using a separate HTML parser):

import BASE_URL, BROWSERS from "./playwright.config.js"; import createSiteMap, readSiteMap from "./sitemap.js"; import playwright from "@playwright/test"; export default async function globalSetup(config) // only create site map if it doesn't already exist try readSiteMap(); return; catch(err) // launch browser and initiate crawler let browser = playwright.devices[BROWSERS[0]].defaultBrowserType; browser = await playwright[browser].launch(); let page = await browser.newPage(); await createSiteMap(BASE_URL, page); await browser.close();

This is fairly boring glue code; the actual crawling is happening within sitemap.js:

createSiteMap determines URLs and writes them to disk.

readSiteMap merely reads any previously created site map from disk. This will be our foundation for dynamically generating tests. (We’ll see later why this needs to be synchronous.)

Fortunately, the website in question provides a comprehensive index of all pages, so my crawler only needs to collect unique local URLs from that index page:

function extractLocalLinks(baseURL) let urls = new Set(); let offset = baseURL.length; for(let href of document.links) if(href.startsWith(baseURL)) let path = href.slice(offset); urls.add(path); return Array.from(urls);

Wrapping that in a more boring glue code gives us our sitemap.js:

import readFileSync, writeFileSync from "node:fs"; import join from "node:path"; let ENTRY_POINT = "/topics"; let SITEMAP = join(__dirname, "./sitemap.json"); export async function createSiteMap(baseURL, page) await page.goto(baseURL + ENTRY_POINT); let urls = await page.evaluate(extractLocalLinks, baseURL); let data = JSON.stringify(urls, null, 4); writeFileSync(SITEMAP, data, encoding: "utf-8" ); export function readSiteMap() try var data = readFileSync(SITEMAP, encoding: "utf-8" ); catch(err) if(err.code === "ENOENT") throw new Error("missing site map"); throw err; return JSON.parse(data); function extractLocalLinks(baseURL) // etc.

The interesting bit here is that extractLocalLinks is evaluated within the browser context — thus we can rely on DOM APIs, notably document.links — while the rest is executed within the Playwright environment (i.e. Node).

Tests

Now that we have our list of URLs, we basically just need a test file with a simple loop to dynamically generate corresponding tests:

for(let url of readSiteMap()) test(`page at $url`, async ( page ) => await page.goto(url); await expect(page).toHaveScreenshot(); );

This is why readSiteMap had to be synchronous above: Playwright doesn’t currently support top-level await within test files.

In practice, we’ll want better error reporting for when the site map doesn’t exist yet. Let’s call our actual test file viz.test.js:

import readSiteMap from "./sitemap.js"; import test, expect from "@playwright/test"; let sitemap = []; try sitemap = readSiteMap(); catch(err) test("site map", ( page ) => throw new Error("missing site map"); ); for(let url of sitemap) test(`page at $url`, async ( page ) => await page.goto(url); await expect(page).toHaveScreenshot(); );

Getting here was a bit of a journey, but we’re pretty much done… unless we have to deal with reality, which typically takes a bit more tweaking.

Exceptions

Because visual testing is inherently flaky, we sometimes need to compensate via special casing. Playwright lets us inject custom CSS, which is often the easiest and most effective approach. Tweaking viz.test.js…

// etc. import join from "node:path"; let OPTIONS = stylePath: join(__dirname, "./viz.tweaks.css") ; // etc. await expect(page).toHaveScreenshot(OPTIONS); // etc.

… allows us to define exceptions in viz.tweaks.css:

/* suppress state */ main a:visited color: var(--color-link); /* suppress randomness */ iframe[src$="/articles/signals-reactivity/demo.html"] visibility: hidden; /* suppress flakiness */ body:has(h1 a[href="/wip/unicode-symbols/"]) main tbody > tr:last-child > td:first-child font-size: 0; visibility: hidden;

:has() strikes again!

Page vs. viewport

At this point, everything seemed hunky-dory to me, until I realized that my tests didn’t actually fail after I had changed some styling. That’s not good! What I hadn’t taken into account is that .toHaveScreenshot only captures the viewport rather than the entire page. We can rectify that by further extending playwright.config.js.

export let WIDTH = 800; export let HEIGHT = WIDTH; // etc. projects: BROWSERS.map(ua => ( name: ua.toLowerCase().replaceAll(" ", "-"), use: ...devices[ua], viewport: width: WIDTH, height: HEIGHT ))

…and then by adjusting viz.test.js‘s test-generating loop:

import WIDTH, HEIGHT from "./playwright.config.js"; // etc. for(let url of sitemap) test(`page at $url`, async ( page ) => checkSnapshot(url, page); ); async function checkSnapshot(url, page) // determine page height with default viewport await page.setViewportSize( width: WIDTH, height: HEIGHT ); await page.goto(url); await page.waitForLoadState("networkidle"); let height = await page.evaluate(getFullHeight); // resize viewport for before snapshotting await page.setViewportSize( width: WIDTH, height: Math.ceil(height) ); await page.waitForLoadState("networkidle"); await expect(page).toHaveScreenshot(OPTIONS); function getFullHeight() return document.documentElement.getBoundingClientRect().height;

Note that we’ve also introduced a waiting condition, holding until there’s no network traffic for a while in a crude attempt to account for stuff like lazy-loading images.

Be aware that capturing the entire page is more resource-intensive and doesn’t always work reliably: You might have to deal with layout shifts or run into timeouts for long or asset-heavy pages. In other words: This risks exacerbating flakiness.

Conclusion

So much for that quick spike. While it took more effort than expected (I believe that’s called “software development”), this might actually solve my original problem now (not a common feature of software these days). Of course, shaving this yak still leaves me itchy, as I have yet to do the actual work of scratching CSS without breaking anything. Then comes the real challenge: Retrofitting dark mode to an existing website. I just might need more downtime.
