This project was bootstrapped with Create React App.

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

yarn build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

yarn eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.

About App

This app is mainly created in admiration of the learning of context component of the reactJs.

• libaray used in it:

1. axios
2. ant-design
3. react-router-dom

axious

• To get data from backend in Lifecycle Hooks i.e

componentDidMount(){
  const promis = axios.get('url')
}

• requests of axios

axios
  .get('url')
  .then(function(respose) {
    //handle success
  })
  .catch(function(error) {
    //handle errors
  });

context or context API

• React's context allows you to share information to any components, without any help of props.
• Context provides a way to pass data through the component tree without having to pass props down manually at every level.

Create file of context.jsx in root path

• context component:

const Context = React.createContext();

• There are two export component :

1. class Provider

For adding in root file App.js
Changing state by using the dispatch redux property

export class Provider extends Component{
  state={
    data:[]
    dispatch:action => this.setState(state => reducer(state,action))
     // you have to define or use this element in other file with the same 'type' component in it and after that help of payload we can change the state.
  };
  componentDidMound(){
    //if you want ot change state in file by 'setState'
  }
  render(){
    return (
      <Context.Provider value={this.state}>
      {this.props.childern}
      </Context.Provider>
    );
  }
}

reducer component:

const reducer = (state, action) => {
  switch (action.type) {
    case 'objcet_in_type':
      return {
        ...state,
        data: action.payload // payload is the change data that comes from the another file where the 'Consumer' used.
      };
    default:
      return state;
  }
};

2. const Consumer

For adding in file where we can use the states or values that provide by the provider.

export const Consumer = Context.Consumer;
