Parcel

Parcel is a zero-config build tool for the web. It is easy to use and get started with, and it can be used to bundle JavaScript, CSS, and other assets into a single file that can be loaded by a web browser.

Here is a simple example of how to use Parcel to bundle your code:

1# Create a Parcel project
2parcel init
3
4# Bundle your code
5parcel src/index.js
6
7# Output file
8dist/index.html

This will create a new dist directory containing a bundled JavaScript file called index.js. You can then open this file in a web browser to view your application.

Parcel can also be used to bundle more complex projects. For example, you can use Parcel to bundle multiple JavaScript files into a single file, or to bundle JavaScript and CSS files into a single file.

Here is an example of how to bundle multiple JavaScript files into a single file with Parcel:

1# Create a Parcel project
2parcel init
3
4# Add a package.json file with the following contents
5{
6  "scripts": {
7    "build": "parcel src/index.js src/main.js"
8  }
9}
10
11# Bundle your code
12npm run build
13
14# Output file
15dist/index.js

This will create a new dist directory containing a bundled JavaScript file called index.js that contains the code from both the index.js and main.js files.

Parcel is a powerful and versatile build tool that can be used to bundle a wide range of web applications. It is a good choice for both beginners and experienced developers.
