Frontend [Applicants] Routes 👶 :

Extend “Create React App” with AirBnB’s ESLint config:

• Extend ESLint configuration with AirBnB’s linting rules

npm i eslint-config-airbnb eslint-config-prettier eslint-plugin-jsx-a11y --save-dev

• Create a .eslintrc file in your project root folder, adding the following configuration:

  This file basically tells to esLint to use airbnb rules and generally how to lint the code.

{
  "extends": [
    "react-app",
    "airbnb",
    "plugin:jsx-a11y/recommended",
  ],
  "plugins": [
    "jsx-a11y"
  ],
  "rules": {
    "semi": 0,
    "react/jsx-filename-extension": [1, { "extensions": [".js", ".jsx"] }],
  }
}

• Add a script to your project to lint your files.
  To lint your codebase, in your package.json you need to add the lint command, in this way:

"scripts": {
  "start": "react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject",
  "lint": "eslint ."

• Arabic font from google font

Material-UI Right-to-left Configuration

• To change the direction of Material-UI components the following steps must be followed:

1. HTML
   the dir attribute should be set on the body, otherwise native components will break

<body dir="rtl">

2. jss-rtl

npm install jss-rtl

3. When a JSS instance with the plugin is created, it should be available to all the components in the component tree. The StylesProvider component enables this:

import { create } from 'jss';
import rtl from 'jss-rtl';
import { StylesProvider, jssPreset } from '@material-ui/core/styles';

// Configure JSS
const jss = create({ plugins: [...jssPreset().plugins, rtl()] });

function RTL(props) {
  return (
    <StylesProvider jss={jss}>
      {props.children}
    </StylesProvider>
  );
}

Arabic font from google font

• A clear arabic font should be chosen, it should be consistent with the design and appearance of the website.
