Good Code is Boring

Daily Blogs 358 - Oct 28th, 12.024

Something I started to notice and think about, is how much most good code is kinda boring.

Clever Code

Go (or "Golang" for SEO friendliness) is my third or fourth programming language that I learned, and it is somewhat a new paradigm for me.

My first language was Java, famous for its Object-Oriented Programming (OOP) paradigms and features. I learned it for game development, which is somewhat okay with Java, and to be honest, I hardly remember how it was. However, I learned from others how much OOP can get out of control and be a nightmare with inheritance inside inheritance inside inheritance.

And then I learned JavaScript after some years... fucking god. But being honest, in the start JS was a blast, and I still think it is a good language... for the browser. If you start to go outside from the standard vanilla JavaScript, things start to be clever. In an engineering view, the ecosystem is really powerful, things such as JSX and all the frameworks that use it, the compilers for Vue and Svelte, and the whole bundling, and splitting, and transpiling of Rollup, ESBuild, Vite and using TypeScript, to compile a language to another, that will have a build process, all of this, for an interpreted language... it is a marvel of engineering, but it is just too much.

Finally, I learned Rust... which I kinda like it. I didn't really make a big project with it, just a small CLI for manipulating markdown, which was nice and when I found a good solution for converting Markdown AST to NPF it was a big hit of dopamine because it was really elegant. However, nowadays, I do feel like it is having the same problems of JavaScript. Macros are a good feature, but end up being the go-to solution when you simply can't make the code "look pretty"; or having to use a library to anything a little more complex; or having to deal with lifetimes. And if you want to do anything a little more complex "the Rust way", you will easily do head to head with a wall of skill-issues. I still love it and its complexity, and for things like compiler and transpilers it feels like a good shot.

Going Go

This year I started to learn Go (or "Golang" for SEO friendliness), and it has being kinda awesome.

Go is kinda like Python in its learning curve, and it is somewhat like C but without all the needing of handling memory and needing to create complex data structured from scratch. And I have never really loved it, but never really hated it, since it is mostly just boring and simple.

There are no macros or magic syntax. No pattern matching on types, since you can just use a switch statement. You don't have to worry a lot about packages, since the standard library will cover you up to 80% of features. If you need a package, you don't need to worry about a centralized registry to upload and the security vulnerability of a single failure point, all packages are just Git repositories that you import and that's it. And no file management, since it just uses the file system for packages and imports.

And it feels like Go pretty much made all the obvious decisions that make sense, and you mostly never question or care about them, because they don't annoy you. The syntax doesn't get into your way. And in the end you just end up comparing to other languages' features, saying to yourself "man... we could save some lines here" knowing damn well it's not worth it. It's boring.

You write code, make your feature be completed in some hours, and compile it with go build. And run the binary, and it's fast.

Going Simple

And writing Go kinda opened a new passion in programming for me.

Coming from JavaScript and Rust really made me be costumed with complexity, and going now to Go really is making me value simplicity and having the less moving parts are possible.

I am becoming more aware from installing dependencies, checking to see their dependencies, to be sure that I'm not putting 100 projects under my own. And when I need something more complex but specific, just copy-and-paste it and put the proper license and notice of it, no need to install a whole project. All other necessities I just write my own version, since most of the time it can be simpler, a learning opportunity, and a better solution for your specific problem. With Go I just need go build to build my project, and when I need JavaScript, I just fucking write it and that's it, no TypeScript (JSDoc covers 99% of the use cases for TS), just write JS for the browser, check if what you're using is supported by modern browsers, and serve them as-is.

Doing this is really opening some opportunities to learn how to implement solutions, instead of just using libraries or cumbersome language features to implement it, since I mostly read from source-code of said libraries and implement the concept myself. Not only this, but this is really making me appreciate more standards and tooling, both from languages and from ecosystem (such as web standards), since I can just follow them and have things work easily with the outside world.

The evolution

And I kinda already feel like this is making me a better developer overhaul. I knew that with an interesting experiment I made.

One of my first actual projects was, of course, a to-do app. I wrote it in Vue using Nuxt, and it was great not-gonna-lie, Nuxt and Vue are awesome frameworks and still one of my favorites, but damn well it was overkill for a to-do app. Looking back... more than 30k lines of code for this app is just too much.

And that's what I thought around the start of this year, which is why I made an experiment, creating a to-do app in just one HTML file, using AlpineJS and PicoCSS.

The file ended up having just 350 files.

Step 1: Plan Your Project Structure 

In a standard full-stack project using Python, Vue.js, and PostgreSQL, the project structure is typically organized into several main directories. The backend directory contains the Python-based backend code, which could use frameworks like Django or Flask. The frontend directory holds the Vue.js frontend code and is responsible for the user interface. The database directory includes scripts and configuration files for setting up and managing the PostgreSQL database. The environment directory stores configuration files, such as environment variables and deployment settings. Finally, the docs directory is dedicated to documentation and notes related to the project. This structure ensures clarity and separation of concerns, making the project easier to manage and scale. 

Step 2: Set Up the Backend with Python 

Choose a Python Framework:  

Flask: Lightweight and flexible for simple APIs. 

Django: A full-fledged web framework with built-in features for authentication, ORM, and more.

Using virtual environments ensures project dependencies remain isolated, a key concept covered in any Python FSD curriculum. 

Install Necessary Packages:  

For Flask: Flask, Flask-Cors, and SQLAlchemy. 

For Django, use core Django packages and DRF (Django Rest Framework) for API handling. 

API Design:  

Develop RESTful endpoints to handle CRUD operations. 

Implement authentication mechanisms like JWT for user management. 

Step 3: Develop the Frontend with Vue.js 

Set Up the Vue.js Environment:  

Use Vue CLI to scaffold your application. This creates a starter project with essential configurations. 

Design Components:  

Break down your application into modular components (e.g., header, footer, forms). 

Use Vue’s data-binding and state management to handle user interactions. 

API Integration:  

Axios or Fetch can be used to connect the Vue.js frontend with your Python backend. 

Styling:  

Choose between frameworks like Vuetify, Tailwind CSS, or Bootstrap to style your application. 

Step 4: Configure the PostgreSQL Database 

Install PostgreSQL:  

Ensure PostgreSQL is installed and running on your system. Tools like pgAdmin simplify database management. 

Set Up the Database:  

Define your schema and relationships. Django’s ORM or Flask’s SQLAlchemy can streamline this process. 

Database Connection:  

Configure your backend to connect to PostgreSQL using libraries like psycopg2. 

Migrations:  

Use migration tools provided by your framework (e.g., Django’s migrate command) to keep your database schema synchronized. 

Step 5: Link the Frontend and Backend 

Cross-Origin Resource Sharing (CORS):  

Enable CORS in your backend to allow API requests from your frontend. 

Environment Variables:  

Use .env files to securely manage API keys, database credentials, and other sensitive information. 

Serve the Frontend:  

Deploy your Vue.js application and configure the backend to serve the frontend (or use a separate web server). 

Step 6: Deployment 

Containerization:  

Use Docker to containerize your application for consistent deployment across environments. 

Hosting Platforms:  

For the backend, consider platforms like Heroku, AWS, or Azure. 

For the front end, platforms like Vercel or Netlify are excellent choices. 

Database Hosting:  

Host PostgreSQL on cloud platforms like AWS RDS or DigitalOcean for better scalability.

One of its biggest strengths is its ability to support a wide range of programming languages and tools, allowing teams to work with the technologies they are most comfortable with.

In this article, we’ll explore the various programming languages and technologies that Microsoft Azure DevOps supports. We’ll also discuss how they are used in different stages of the software development lifecycle.

1. Scripting Languages for Automation

Automation is a key principle of DevOps, and Azure DevOps offers powerful automation tools through its Azure Pipelines. Scripting languages play an essential role in creating automated workflows for builds, deployments, and environment configuration.

PowerShell

PowerShell is a scripting language developed by Microsoft, commonly used in Windows environments. It is widely used in Azure DevOps pipelines to:

Automate deployment tasks

Configure environments

Manage Azure resources

Because Azure is a Microsoft product, PowerShell integrates very well with its services and is often the preferred choice for Windows-based automation.

Bash

Bash is a Unix-based shell and scripting language commonly used in Linux environments. It’s also supported in Azure DevOps and is especially useful in cross-platform scenarios. Bash scripts are commonly used for:

Installing dependencies

Running deployment commands

Managing Linux-based build agents

Both PowerShell and Bash can be directly used in pipeline tasks, allowing teams to choose the scripting language that fits their environment best.

2. Source Code Management with Git

While Git is not a programming language, it is an essential part of the DevOps workflow. Azure Repos, a part of Azure DevOps, provides a robust Git-based version control system.

Git Repositories in Azure DevOps

Git allows teams to store and manage their source code. Azure Repos lets developers use Git for:

Branching and merging code

Collaborating with team members

Code reviews using pull requests

You can use any programming language within Git repositories in Azure DevOps. Commonly used ones include:

C#

Java

Python

JavaScript/TypeScript

PHP

Go

Ruby

This makes Azure DevOps flexible enough to support projects of any scale and tech stack.

3. Programming Languages for Application Development

Azure DevOps is a language-neutral platform, meaning you are not restricted to any single language. Here are some of the most popular programming languages supported for application development.

C#

C# is widely used with Microsoft’s .NET framework. If you are building web applications, APIs, or services using .NET technologies, Azure DevOps offers full support through tools like Visual Studio, MSBuild, and .NET CLI.

Java

Java is often used for enterprise-level applications. Azure DevOps supports Java build tools like Maven and Gradle, and it integrates well with popular Java-based servers like Tomcat or JBoss.

Libraries And Tools You Should Consider For Your Next React Native App Setup

React Native is such a technology that has changed the mobile app development process. It was introduced by Facebook to build cross-platform mobile apps. React Native used a JavaScript library and is built by an awesome open source community, which will help in accelerating the development process.

Today in this article, we will discuss several libraries and tools to use for your next react native app setup and I hope this helps you make the right decision.

1. React-native Base Framework

On the react-native official website, you will get two ways of setting up your react native app: Expo CLI or React native CLI.

Expo CLI

Quick to start writing the first screen.

Quick distribution and installation of the app.

Great for demo or POC apps.

React Native CLI

Easy to add android and iOS native code.

For large-scale applications.

2. Static Typing

If you are a JavaScript developer, you understand the need for strict typing for the code. React Native use type checking that helps with early error detection and increases code readability. Typescript is a strict syntactical superset of JavaScript because it is an open-source programming language.

Typescript

Huge community and widely used in the backend and front end frameworks like NodeJs, Angular 2+, Vue Js, etc.

Faster than flow.

Flow

Flow is not a programming language, it’s just a static type checker for JavaScript.

Premium React support.

3. HTTP Request Client

As most of the applications require to call APIs that is why you need one HTTP client with the help of Axios.

Axios

A well-tested and classic way of doing it.

Graphql Appolo client

It helps in caching the data.

One client for REST APIs and Graphql APIs.

4. Managing Reusable UI Components

React Native provides you reuse of code features. You can simply maintain a codebase and keep a consistent UI, you’ll need to make use of cloud component hubs.

Bit. dev

Continuously publish components from any codebase.

Easily import/install components into any repository.

Document and organize components, all in one place.

Excellent support for React Native.

5. Unit Testing Setup

We all love a quality website or in simple words a website with fewer bugs. For this quality, unit testing is super important.

Jest And Enzyme

It is a very simple testing framework and works with multiple platforms such as Typescript, Node, React, Angular and Vue.

Comes with a mocking framework as well.

Huge community.

6. Navigation

Through React Native you can manage more than a couple of screens then you need to define routing and navigation which is scalable and easy to maintain.

React-navigation

Huge community

Most of the use cases covered name-based routing, passing data from routes, Tab navigation, authentication flows, deep linking, analytics trigger, etc.

You can also use pre-defined navigation react hooks

7. Forms

The native forms in React are not fun writing, I have struggled in most of the scenarios, hence we need a better way of doing forms which is easy to write, maintainable, and importantly developer-friendly. You can consider the following options:

Formik

Huge community.

React hook form

Better performance compared to formik.

It is developer-friendly and easy to use with React-hook-form.

8. Config Loader

You required a nice framework to set up for configs. Try to make your app portable across environments, scalable, enabled for continuous deployment.

A Font-Like SVG Icon System for Vue

Managing a custom collection of icons in a Vue app can be challenging at times. An icon font is easy to use, but for customization, you have to rely on third-party font generators, and merge conflicts can be painful to resolve since fonts are binary files.

Using SVG files instead can eliminate those pain points, but how can we ensure they’re just as easy to use while also making it easy to add or remove icons?

Here is what my ideal icon system looks like:

To add icons, you just drop them into a designated icons folder. If you no longer need an icon, you simply delete it.

To use the rocket.svg icon in a template, the syntax is as simple as <svg-icon icon="rocket" />.

The icons can be scaled and colored using the CSS font-size and color properties (just like an icon font).

If multiple instances of the same icon appear on the page, the SVG code is not duplicated each time.

No webpack config editing is required.

This is what we will build by writing two small, single-file components. There are a few specific requirements for this implementation, though I’m sure many of you wizards out there could rework this system for other frameworks and build tools:

webpack: If you used the Vue CLI to scaffold your app, then you’re already using webpack.

svg-inline-loader: This allows us to load all of our SVG code and clean up portions we do not want. Go ahead and run npm install svg-inline-loader --save-dev from the terminal to get started.

The SVG sprite component

To meet our requirement of not repeating SVG code for each instance of an icon on the page, we need to build an SVG “sprite.” If you haven’t heard of an SVG sprite before, think of it as a hidden SVG that houses other SVGs. Anywhere we need to display an icon, we can copy it out of the sprite by referencing the id of the icon inside a <use> tag like this:

<svg><use xlink:href="#rocket" /></svg>

That little bit of code is essentially how our <SvgIcon> component will work, but let’s go ahead create the <SvgSprite> component first. Here is the entire SvgSprite.vue file; some of it may seem daunting at first, but I will break it all down.

<!-- SvgSprite.vue --> <template>   <svg width="0" height="0" style="display: none;" v-html="$options.svgSprite" /> </template> <script> const svgContext = require.context(   '!svg-inline-loader?' +    'removeTags=true' + // remove title tags, etc.   '&removeSVGTagAttrs=true' + // enable removing attributes   '&removingTagAttrs=fill' + // remove fill attributes   '!@/assets/icons', // search this directory   true, // search subdirectories   /\w+\.svg$/i // only include SVG files ) const symbols = svgContext.keys().map(path => {   // get SVG file content   const content = svgContext(path)    // extract icon id from filename   const id = path.replace(/^\.\/(.*)\.\w+$/, '$1')   // replace svg tags with symbol tags and id attribute   return content.replace('<svg', `<symbol id="${id}"`).replace('svg>', 'symbol>') }) export default {   name: 'SvgSprite',   svgSprite: symbols.join('\n'), // concatenate all symbols into $options.svgSprite } </script>

In the template, our lone <svg> element has its content bound to $options.svgSprite. In case you’re unfamiliar with $options it contains properties that are directly attached to our Vue component. We could have attached svgSprite to our component’s data, but we don’t really need Vue to set up reactivity for this since our SVG loader is only going to run when our app builds.

In our script, we use require.context to retrieve all of our SVG files and clean them up while we’re at it. We invoke svg-inline-loader and pass it several parameters using syntax that is very similar to query string parameters. I’ve broken these up into multiple lines to make them easier to understand.

const svgContext = require.context( '!svg-inline-loader?' + 'removeTags=true' + // remove title tags, etc. '&removeSVGTagAttrs=true' + // enable removing attributes '&removingTagAttrs=fill' + // remove fill attributes '!@/assets/icons', // search this directory true, // search subdirectories /\w+\.svg$/i // only include SVG files )

What we’re basically doing here is cleaning up the SVG files that live in a specific directory (/assets/icons) so that they’re in good shape to use anywhere we need them.

The removeTags parameter strips out tags that we do not need for our icons, such as title and style. We especially want to remove title tags since those can cause unwanted tooltips. If you would like to preserve any hard-coded styling in your icons, then add removingTags=title as an additional parameter so that only title tags are removed.

We also tell our loader to remove fill attributes, so that we can set our own fill colors with CSS later. It’s possible you will want to retain your fill colors. If that’s the case, then simply remove the removeSVGTagAttrs and removingTagAttrs parameters.

The last loader parameter is the path to our SVG icon folder. We then provide require.context with two more parameters so that it searches subdirectories and only loads SVG files.

In order to nest all of our SVG elements inside our SVG sprite, we have to convert them from <svg> elements into SVG <symbol> elements. This is as simple as changing the tag and giving each one a unique id, which we extract from the filename.

const symbols = svgContext.keys().map(path => { // extract icon id from filename const id = path.replace(/^\.\/(.*)\.\w+$/, '$1') // get SVG file content const content = svgContext(path) // replace svg tags with symbol tags and id attribute return content.replace('<svg', `<symbol id="${id}"`).replace('svg>', 'symbol>') })

What do we do with this <SvgSprite> component? We place it on our page before any icons that depend on it. I recommend adding it to the top of the App.vue file.

<!-- App.vue --> <template>   <div id="app">     <svg-sprite /> <!-- ... -->

The icon component

Now let’s build the SvgIcon.vue component.

<!-- SvgIcon.vue --> <template>   <svg class="icon" :class="{ 'icon-spin': spin }">     <use :xlink:href="`#${icon}`" />   </svg> </template> <script> export default {   name: 'SvgIcon',   props: {     icon: {       type: String,       required: true,     },     spin: {       type: Boolean,       default: false,     },   }, } </script> <style> svg.icon {   fill: currentColor;   height: 1em;   margin-bottom: 0.125em;   vertical-align: middle;   width: 1em; } svg.icon-spin {   animation: icon-spin 2s infinite linear; } @keyframes icon-spin {   from {     transform: rotate(0deg);   }   to {     transform: rotate(359deg);   } } </style>

This component is much simpler. As previously mentioned, we leverage the <use> tag to reference an id inside our sprite. That id comes from our component’s icon prop.

I’ve added a spin prop in there that toggles an .icon-spin class as an optional bit of animation, should we ever need. This could, for example, be useful for a loading spinner icon.

<svg-icon v-if="isLoading" icon="spinner" spin />

Depending on your needs, you may want to add additional props, such as rotate or flip. You could simply add the classes directly to the component without using props if you’d like.

Most of our component’s content is CSS. Other than the spinning animation, most of this is used to make our SVG icon act more like an icon font¹. To align the icons to the text baseline, I’ve found that applying vertical-align: middle, along with a bottom margin of 0.125em, works for most cases. We also set the fill attribute value to currentColor, which allows us to color the icon just like text.

<p style="font-size: 2em; color: red;">   <svg-icon icon="exclamation-circle" /><!-- This icon will be 2em and red. -->   Error! </p>

That’s it!  If you want to use the icon component anywhere in your app without having to import it into every component that needs it, be sure to register the component in your main.js file:

// main.js import Vue from 'vue' import SvgIcon from '@/components/SvgIcon.vue' Vue.component('svg-icon', SvgIcon) // ...

Final thoughts

Here are a few ideas for improvements, which I intentionally left out to keep this solution approachable:

Scale icons that have non-square dimensions to maintain their proportions

Inject the SVG sprite into the page without needing an additional component.

Make it work with vite, which is a new, fast (and webpack-free) build tool from Vue creator Evan You.

Leverage the Vue 3 Composition API.

If you want to quickly take these components for a spin, I’ve created a demo app based on the default vue-cli template. I hope this helps you develop an implementation that fits your app’s needs!
