In the world of web development, task automation has become essential to speed up the process of creating applications and websites. One of the most popular tools for this purpose is Parcel, a fast and easy-to-use module packager. In this Parcel starter tutorial guide, I'll show you how to get started with this powerful tool and get the most out of its features.
What is Parcel and why should you use it?
Parcel is a bundler or module packager for web applications. Its main advantage is its ease of use, since it requires minimal configuration. Additionally, Parcel is extremely fast, thanks to its focus on concurrency and task parallelization.
One of the standout features of Parcel is its ability to automatically support a wide range of technologies, such as JavaScript, CSS, HTML, images, fonts, and more. This means you don't have to worry about manually configuring each of these technologies, Parcel takes care of it for you.
Another advantage of Parcel is its ability to perform automatic code transpilation and minification. This means you can write your code in advanced languages like TypeScript or JSX, and Parcel will compile it into cross-browser-compatible JavaScript.
Initial Parcel Setup
To start using Parcel, you must have Node.js installed on your computer. You can download and install it from its official website. Once you have installed Node.js, you can install Parcel globally by running the following command in your terminal:
npm install -g parcel-bundler
Next, create a new folder for your project and go to it from your terminal. Once inside your project folder, run the following command to initialize a Parcel project:
parcel init
This command will create a file package.json in your project folder, which contains the basic configuration of your project.
Creating your first HTML file
Parcel uses an HTML file as the entry point for your application. Create a new HTML file in your project folder and name it whatever you want:
touch index.html
Open the file index.html in your favorite code editor and add the following HTML code:
<!DOCTYPE html> <html lang="es"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>My first application with Parcel</title> </head> <body> <h1>Hello World!</h1> <script src="./index.js"></script> </body> </html>
This basic HTML code creates a web page with a header that displays a greeting of "Hello World!" and load a JavaScript file called index.js using the tag <script>.
Creating your first JavaScript file
Create a new JavaScript file in your project folder and name it index.js:
touch index.js
Open the file index.js in your code editor and add the following basic JavaScript code:
console.log("Hello World!");
This code simply prints "Hello World!" in the browser console.
Execution of your project with Parcel
Once you have created your HTML file and your JavaScript file, you can run your project with Parcel. From your terminal, run the following command:
parcel index.html
Parcel will start a local server on your machine and show you the URL where you can access your application in your browser. You will also be able to see detailed log messages in your terminal that will tell you the build status of your project.
