When it comes to Web Development for Single Page Applications , JavaScript frameworks are one of the most favored platform for developers & businesses in today’s time.
In order to do that, knowing and understanding more of the top JavaScript Frameworks in today’s time is necessary like Angular JS2 to Angular 6, ReactJS, VueJS,MeteorJS, PolymerJS ,NodeJS and so on.
create a basic Web App using ReactJS.
You’ll need to have Node >= 6 and npm >= 5.2 on your machine.
If not installed, go through the following link:
a) NodeJs=> https://nodejs.org/en/
b) NPM=> https://docs.npmjs.com/getting-started
and after installation check node and npm version by following commands:
node -v
npm -v
We will use npm to install the create-react-app command line interface (CLI) globally (-g
).
Open up your terminal and run npm install -g create-react-app
:
Now that you have the CLI available for use, navigate to the parent directory that you would like to place the application within. Then, run create-react-app
with the name you would like to use for your project (just with no capital letters ).
create-react-app <name-of-app>
create-react-app my-app
cd my-app
npm start
After creating the app, your file structure would be following.
|-my-app/ |--README.md |--node_modules/ |--package.json |--.gitignore |--public/ |---favicon.ico |---index.html |--src/ |---App.css |---App.js |---App.test.js |---index.css |---index.js |---logo.svg
To create or edit components modify under src/
folder files.
a.Install reactstrap and Bootstrap from NPM. Reactstrap does not include Bootstrap CSS so this needs to be installed as well:
npm install bootstrap --save npm install --save reactstrap react react-dom
b.Import Bootstrap CSS in the src/index.js
file:
import 'bootstrap/dist/css/bootstrap.min.css';
{/*Example.*/}
import { Button , Alert, UncontrolledAlert,Input } from 'reactstrap';
class App extends Component {
render () {
return(
<div className="container">
<Button>Click</Button>
<Alert color="primary">
This is a primary alert — check it out!
</Alert>
<UncontrolledAlert color="dark">
This is a UncontrolledAlert dark alert — check it out!
</UncontrolledAlert>
</div>
)
}
}
Adding sass or scss to your create-react-app project will first require you to eject which can be done by executing the following command in your project’s base directory. npm run eject
You’ll be asked for approval because the action is permanent. Once this command has successfully run, you should see a config
and scripts
folder created. They contain all the build scripts necessary for building the started app. Among them is the webpack.config.dev.js
and webpack.config.prod.js
files, which is our focus.
Also note that npm run eject
updates your dependencies with other packages which it has previously abstracted from you. You can view those new dependencies in your package.json
.
And run the following commands
a) npm i sass-loader node-sass webpack --save-dev
You’ll also need style-loader
and css-loader
:
b)npm i style-loader css-loader --save-dev
Then rename your .css files to .scss and import to the component files.
Example :
This is a assuming you have a directory structure like this:
|--app.js
|--style.scss
|--components/
|--containers/
Per usual, in style.scss you can import your other sass files like so:
@import 'buttons'; @import 'modal';
And so on.
