Looking for a good book on Angular.js? This is a book we liked and exclusively covering its review on our website.Pro AngularJS(By: Adam Freeman )Also known as Angular or Angular.js, AngularJS is a leading open-source web application framework that is used primarily for building dynamic JavaScript single-page applications.With increasing popularity of the framework, it has become necessary to understand the salient features for programming any software. Written by Adam Freeman, this is one of the best books on the topic that offers comprehensive information about the Angular.js framework.The 1st part of the book offers a step-by-step process to build a real application while it offers information about various features. This section also offers an introduction to JavaScript, CSS, and HTML for beginners.The second and third part of the book offers information regarding various features and their use. Adam Freeman is an experienced IT professional, who is now retired after working in many senior positions such CEO and Chief Technology Officer at a global bank.Who Should Read This Book?As per the author, this book is primarily targeted towards web developers with functional knowledge of CSS, HTML, and JavaScript. As the books start with the introduction and building of an actual application, this book is good for readers who have set up the required environment and are ready to start building an application. This book is also a good option for the people who believe in learning with a practical demonstration about how to create dynamic and rich web apps by using AngularJS and how to customize and extend this framework. This book is also targeted towards those developers who are involved in testing, refining, and deployment of AngularJS projects in any organization.What Is Good In This Book?As per the author, this book is primarily targeted towards web developers who have some functional knowledge regarding the development of websites. This book starts with the steps for building an online application, specifically an online sports store; however, the web developer can start building an online application similar to a sports store and include various features as required. The other parts of the book take up these features again one by one and explain their use with suitable examples. In this way, the book offers both practical and theoretical knowledge of AngularJS for readers.The author starts with MVC pattern concepts and its benefits with separation of presentation code, data, and logic. He further shows how to use various AngularJS features for the production of professional-quality results. The author carefully unwraps the nuts-and-bolts of the software framework in order to build an actual application.The language of the book is very easy, concise and includes detailed information to avoid common problems. The building of an actual application enhances the confidence of the learner and increases his or her thirst to know more. The author fulfills this desire by taking up every feature topic by topic, in other sections of the book.What Is Not So Good In This BookThe author has used many pre-installed programs such as Deployd, MongoDB, and NodeJS while describing the process of creating a new application. However, the Deployd environment is defunct in the software world today.The author mentions this fact but does not give an alternative. In most cases, the student is unable to install or run Deployd environment or it takes a lot of time. Also, most other software books define various features of the software first, and then they go on to build an application. However, this book reverses the order. Some people who like to learn in a sequential manner way do not appreciate this method.Although this book does not use a conventional method to teach AngularJS to readers, it uses an innovative and effective method to teach this software framework. AngularJS is one of the upcoming open-source web applications much in demand in the software world.

For the web developer who has functional knowledge of web designing languages such as CSS and HTML, this is one of the ideal books to buy, for developing dynamic web applications.

hey I hope this isn't super annoying, but do u have any tips for that neocities template situation u made a while ago? ive been stuck at setting up my node environment (it wont recognize it as an internal/external command operable program or batch file, if that helps.)

again i TOTALLY understand if this is just my problem to figure out but I cant find helpful info elsewhere...

i'm assuming you're on windows!

so, windows has an "environment variable" called PATH. an environment variable is basically just a value that can be used by any program that can see it. your command line uses PATH to look for executable files that it can run as commands

so for example, imagine you have an executable (.exe) file at, say: -> C:/FileMaker/filemaker.exe in this case, if you add "C:/FileMaker/" to your PATH, then you can go in your command line and type "filemaker", and it would run filemaker.exe.

i'm assuming you're trying to run npm in your command line. however, if there is no npm.exe in your PATH, and you try to run npm i, then it'll give you "not recognized as an internal/external command".

this means one of the following:

npm is not installed. it can be installed bundled with node.js at the node.js website, or through nvm (or nvm-windows). when you install it with node.js, make sure "add to PATH" is enabled!

2. npm IS installed, but it is not in your PATH. this is weird and i'm not sure why it would happen, but if you can find npm.exe, this is quite easily remedied.

search for system "environment variables" in your computer. i use win10; for win10, there is a button called "Environment variables..." that opens a second window. then you find Path and then double click that, which opens a third window, then you wanna add the folder path to the end of the list

in case it helps and you need to track down npm.exe manually, i have two npm.exe files at these places, which might match your setup:

C:/Program Files/nodejs/npm.exe C:/Users/[user]/AppData/Roaming/npm/npm.exe

3. npm IS installed and it IS in your path, but your command line cannot see the environment variables. the primary reason for this would be that you did not restart the command line after installing node and/or updating the environment variables; go ahead and do that if you haven't. the secondary reason for this would be you're using a command line in something else (like vs code), and for some reason in that situation updating the environment variables can be very finnicky. try using your system's command line instead.

worst case scenario, you can also replace "npm" in your command line with the full path to npm. like: "C:/Program Files/nodejs/npm.exe i". this would work!

(sometimes using the "where" command helps to locate stuff, like "where npm", but i dont know how where actually works; for all i know it could be using PATH as well, in which case it would be useless for finding things not already in your PATH.)

How to Send Form Data Using Axios Post Request in React

Many developers use React, a leading programming language for app development. Industry leaders prefer React for cross-platform application development. A proper understanding of React and the library is essential to work well for the project. If you want to handle react project properly, you can hire react developer and finish the task.

As a React developer, sending form data to a server in react with the Axios. Processing axios is an important javascript library. It is the best way to make HTTP requests from a browser or nodejs. Individuals must understand how to use the Axios to make a post request and send form data.

About Axios:

Axios acts as an HTTP client for JavaScript that works in browser and node.js. It is an easy-to-use and lightweight library that delivers the perfect interface for HTTP requests. Axios can build on top of XMLHttpRequest API and fetch API.

On the other hand, it supports promise API and intercepts responses. Axios is responsible for transforming requests, canceling requests, and response data. It is excellent for changing JSON data and provides client-side support to safeguard from the XSRF. It supports browsers like Safari, Mozilla Firefox, Google Chrome, Edge, and IE.

Form data:

Form data is the encoding type that transfers to the server for processing. Other encoding types can be utilized for non-file transfer like plain, text, application/x-www-form-urlencoded, and a lot more. React developer helps you in sending form data in react projects with Axios.

If form-data lets files to include in form data, plain or text propel data as plain text without encoding. It is applicable for debugging and not for production. Application/x-www-form-urlencoded instructs data as a query string. Encoding type can be included in HTML with enctype attribute.

Send form data in the Axios request:

Sending form data in the React app to the server is an important task among many developers. Axios is an important library for making HTTP requests quickly in React. You can understand the important process of sending form data in the react project using Axios.

While using Axios, developers easily make post requests and set the data they wish to send as a request body. If you carry out this process, you can utilize the Axios.post() method that acquires two arguments. It obtains arguments like server URL and data you need to send.

FormData object joins two fields with matching values. It makes HTTP requests to specific URLs with a FormData object. It uses them as a request body and sets the content-type header to multipart or form data.

Once the request is successful, the response can log into the console. If the request is abortive, the error response can log to the console. Using Axios in the project requires installing Axios first. You can install it with the proper command.

Launch react project:

Whether you have a project already, you don’t need to launch. If you don’t have any projects on your device, you can create them first.

You can open a terminal and run the required command.

npx create-react-app axios-form

Once project creation is over, you can go to the project directory.

Install axios:

To use Axios for post requests in the React project, you must install it properly. You can use the following command to install the Axios.

npm install axios

After successfully installing the Axios, you can carry out sending the form data in a project with the Axios post request.

Create form component:

When it comes to the React project, you must make a new component for form. You can name it and save it with .js

// src/Form.js

import React, { useState } from ‘react’;

import axios from ‘axios’;

function Form() {

const [formData, setFormData] = useState({

name: ‘’,

email: ‘’,

});

const handleChange = (e) => {

const { name, value } = e.target;

setFormData({ …formData, [name]: value });

};

const handleSubmit = async (e) => {

e.preventDefault();

try {

const response = await axios.post(‘YOUR_API_ENDPOINT’, formData);

console.log(‘Form data submitted successfully:’, response.data);

} catch (error) {

console.error(‘Error submitting form data:’, error);

}

};

return (

<label>

Name:

<input

type=”text”

name=”name”

value={formData.name}

onChange={handleChange}

</label>

<br />

<label>

Email:

<input

type=” email”

name=” email”

value={formData.email}

onChange={handleChange}

</label>

<br />

<button type=”submit”>Submit</button>

</form>

);

}

export default Form;

In this component, you can label the form with two input fields. You can utilize the useState hook to deal with form data. Axios is ideal for making the post request when the form submits successfully.

Import and apply form component:

After creating the form component, you need to import and apply the form component to the project.

// src/App.js

import React from ‘react’;

import Form from ‘./Form’;

function App() {

return (

<h1>React Form with Axios POST Request</h1>

</div>

);

}

export default App;

Replace your_api_endpoint:

In the form component, you can replace your_api_endpoint with the actual endpoint. It is easy to send the form data in a project and complete them easily

Run React application:

After the above step is over, it is time to run the React application with the following command like

npm start

React application is running and allows you to access it in the browser. You can fill out the form and click the submit button. You must view the form data that is sent to a specified API endpoint in the browser console. You can try the necessary steps for the form data sending in the project utilizing the Axios post request.

Conclusion:

Overall, the above details are useful to understand the process of sending the form data in react with Axios. With the help of a hire react expert, you can get the proper guidance and support to handle this process.

Experts assist you in integrating the form component with the server-side endpoint and dealing with the data effectively in a project. Axios makes a form data sending process in the react app development project. So, you can work with the skilled and knowledgeable react expert and obtain an ideal solution for challenges.

How to Install Node.js on Linux Using Different Methods?

Node JS is an open-source, back-end Javascript code outside a web browser. Here are the steps on how to install Node.js on Linux using various methods. hire node js develoepr

Node.js is a cross-platform that runs on the V8 engine and executes Javascript code outside a web browser. It also allows developers to use Javascript to write command-line tools and run scripts server-side to produce dynamic web page content before the page is sent to the user’s web browser.

.js is a standard filename extension for Javascript code, but Node.js doesn’t refer to a file in this context.

Overview of Node.js

Node.js allows the creation of web servers and networking tools using Javascript and modules that handle various core functionalities. Javascript is the only language that Node.js supports natively. As a result, Node.js applications can be written in Clojure script, Dart, and others. It is officially supported on macOS, Linux, and Microsoft Windows 8.1.

Node.js brings event-driven programming to web servers and allows the development of fast web servers in JavaScript. It connects the ease of a scripting language with the power of Unix network programming. It was built on top of Google’s V8 Javascript engine since it was open-sourced under the BSD license. The Node.js developer community has developed web frameworks to accelerate the development of applications. The frameworks include Socket.IO, Derby, Express.js, Feathers.js, and others.

Modern desktop IEDs provide debugging features for Node.js applications. These IDEs include JetBrains, Microsoft Visual Studio, or TypeScript with Node definitions. It is supported across several cloud hosting programs like Google Cloud Platform, Joyent, and others.

Install NodeJS on Linux Using NVM

This is the best way to install Node.js. NVM is a bash script used to manage multiple Node.js versions. It allows us to install and uninstall Node.js and switch from one version to another. The best thing is we can install any available Node.js version of our choice using NVM.

Install Node.js on Linux using your distribution’s package manager

It is available in the default repositories of most Linux distributions. If you want to have a stable Node.js on your Linux, you can install it using the distribution package manager.

On Arch Linux and its derivatives like Antergos, Manjaro Linux, run the “$ sudo pacman -S nodejs npm” command to install it.

How to Install Node.js and NPM on Windows and Mac?

Quick Overview:

This guide gives a fast and simple stroll through for introducing Node.js and NPM on two Windows and Mac. From downloading the right rendition to confirming the establishment, we cover every one of the essential moves toward preparing your set up and to begin creating.

Introduction:

Here is our detailed guide on introducing Node.js and NPM on Windows and Mac! Node.js has turned into a foundation in current web improvement, offering a productive and versatile method for making network applications. Close by it, Node Package Manager (NPM) fills in as the help for overseeing bundles in Node.js. Whether you’re a fledgling venturing into the universe of improvement or an accomplished proficient hoping to find a way to improve your abilities, this guide will walk you through the establishment cycle in a clear, bit-by-bit way.

What is NPM

NPM, or Node Package Manager, is a priority apparatus in the domain of JavaScript and online development. It is the default package manager for Node.js, a Node.js runtime.

NPM is utilized to oversee project conditions by introducing, refreshing, and dealing with the numerous libraries and bundles that an undertaking might require. Little utilities to frameworks are examples of these packages.

Each bundle incorporates a form number and a rundown of conditions, guaranteeing that ventures have all that they need to flawlessly execute. Moreover, NPM provides an enormous assortment of open-source packages, making it a significant asset for developers wishing to utilize existing arrangements or offer their work to others.

This capacity further develops improvement processes as well as empowers a worldwide developer community of sharing and cooperation.

Components of NPM

Package Registry: NPM houses a tremendous online database set of public and confidential packages, permitting developers to transfer and share their code, as well as download and utilize code shared by others. This registry is a broad vault that contains a huge number of bundles, making it an indispensable asset for JavaScript developers.

Command Line Interface (CLI): NPM gives an order line interface that developers use to collaborate with the package registry, oversee project conditions, and run scripts. This CLI instrument is fundamental for introducing, refreshing, and overseeing packages within a project, and it offers different orders to smooth out these processes.

Package.json File: The package.json file is a key component in any Node.js project using NPM.It contains metadata about the task, like name, adaptation, and conditions. This document is utilized to give data to NPM that permits it to distinguish the undertaking as well as handle the venture’s conditions.

What’s NodeJS?

Node.js is a cross-stage open-source runtime climate for executing JavaScript code beyond a program. JavaScript was previously utilized to a great extent for client-side prearranging in web browsers.

Node.js, then again, permits developers to use JavaScript for server-side scripting, which includes running contents on the server to produce dynamic website page content before the page is transmitted to the user’s web browser.

Subsequently, Node.js represents a “JavaScript all over” worldview, uniting on the online application improvement around a solitary programming language as opposed to isolating dialects for server-and client-side contents.

Its non-blocking, occasion-driven architecture is considered magnificent execution, making it ideal for creating versatile network applications, for example, web servers, chat apps, and real-time communication apps.

Node.js utilizes the V8 JavaScript engine, which is the very motor that drives Google Chrome and gives astounding execution and rich capacities for server-side applications.

To begin with Node.js and NPM, you’ll require a couple of fundamental components:

Operating System Compatibility: Node.js and NPM are cross-stage and might be introduced on Windows, macOS, and Linux. For the best similarity and security, ensure your working framework is state-of-the-art.

Node.js Installation: In light of the fact that NPM is incorporated with Node.js, you should initially introduce Node.js. It is accessible for download from the Node.js site. Select the right adaptation for your situation; for the most part, the LTS (long-term maintenance) variant is liked for its unwavering quality and broadened support.

Text Editor or Integrated Development Environment (IDE): A decent code manager or Integrated Development Environment (IDE) is fundamental. Visual Studio Code, Brilliant Message, and Atom are phenomenal decisions for JavaScript and Node.js improvement.

fundamental JavaScript Knowledge: In light of the fact that Node.js is a JavaScript runtime, having a central comprehension of JavaScript is required. Despite the fact that you needn’t bother to be a specialist, knowledge of JavaScript syntax and standards will be very advantageous.

Skills in Command Line Interface (CLI): Node.js and NPM frequently cooperated with utilizing an order line interface. Fundamental CLI capacities are required, for example, directories and running commands.

Internet access is required to download Node.js and NPM packages, as well as to access online resources, documentation, and communities.

Understanding of Version Control (Optional but Recommended): Comprehension of a rendition control framework, for example, Git can be helpful, particularly while dealing with bigger tasks or helping out others.

Curiosity and eagerness to learn: The JavaScript biological system is enormous and steadily evolving. A learning and exploring mentality is pivotal in staying aware of new devices, systems, and best practices.

Run the Installer:

Open the downloaded .pkg file.

Follow the prompts in the installation wizard. Agree to the terms, and continue with the default settings.

Using Homebrew (Alternative Method):

If you prefer using a package manager, you can install Node.js and NPM using Homebrew.

First, install Homebrew by opening the Terminal and running:

Then, install Node.js with:

Verify Installation:

Open Terminal.

Run node -v to check the Node.js version.

Run npm -v to ensure NPM is installed.

By following these steps, you will have successfully installed Node.js and NPM on your Windows or Mac computer, setting you up for developing applications with Node.js.

How to Install Node Using “Homebrew”?

Step 1-

Install Node.js and NPM:

Installing Node.js and NPM on your Mac is very easy using Homebrew. Homebrew simplifies the process by managing the download, unpacking, and installation of Node and NPM for you.

First, open your Terminal and run the following command:

brew install node

This command will download and install the necessary files for Node.js and NPM. Wait for the process to complete.

How to Install Node Using NVM – Node Version Manager?

Installing Node.js using NVM (Node Version Manager) is a great choice, especially if you need to manage multiple versions of Node.js. NVM allows you to install and switch between different Node versions with ease. Here’s how to do it:

For Linux and macOS:

Install NVM:

Open your terminal.

To install NVM, run the following curl or wget command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

The script clones the NVM repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

Activate NVM:

To activate NVM, either close and reopen your terminal or run the following command:source ~/.bashrc

Alternatively, for zsh users: source ~/.zshrc.

Check if NVM Was Installed Successfully:

Run nvm –version to check if NVM was installed successfully.
