Getting Started with Parcel


Parcel is a web application bundler.

  • Parcel is a web application bundler.
  • It offers blazing fast performance utilizing multicore processing, and requires zero configuration.
Install parcel using npm: 

npm install -g parcel-bundler

Create a package.json file in your project directory using:

npm init -y
Next, create an index.html and index.js file.
<html>
<body>
  <script src="./index.js"></script>
</body>
</html>
console.log("hello world");

Parcel has a development server built in, which will automatically rebuild your app as you change files and supports hot module replacement for fast development. Just point it at your entry file:

parcel index.html

Now open http://localhost:1234/ in your browser. You can also override the default port with the -p <port number> option.

parcel index.html -p <port number>

Use the development server when you don't have your own server, or your app is entirely client rendered. If you do have your own server, you can run Parcel in watch mode instead. This still automatically rebuilds as files change and supports hot module replacement, but doesn't start a web server.

parcel watch index.html

When you're ready to build for production, the build mode turns off watching and only builds once. See the Production section for more details.

If the output of: git config core.sharedRepository is not  group  or  true  or  1  or some mask, try running: git config core.sharedRepository group and then re-run the recursive  chmod  and  chgrp  (see “Repair Permissions” above). The operating system doesn’t interpret a setgid bit o...

Why ReactJS ?

I was decided to learn ReactJs. And asking my self why I want to learn React. What can I do or build using React? To get the answer I do some Researchs and make couple of important notes. Hope It will help who have interest to learn ReactJS. Lets know what is React First.  React is a JavaScript library for building User Interface s. Very often it’s misinterpreted as tool, framework, language. React allows developers to create large web applications that use data which can change over time, without reloading the page. Its main goal is to be fast, simple and scalable. React processes only user interface in applications ( source ).   It also can be use along with other JS freamwork.  To learn More visit :  https://reactjs.org/ As Inspired from Simon Sinek The author of "Start with Why", firstly I was finding my why's.
