react-context-hocconsumer

中文文档

Simple encapsulation based on the React.createContext, provides a HOC of Consumer, Supports mounting props after context resolution. If you use Redux's connect, it should be easy to get started.

• required：React >= 16.3

install:

npm i react-context-hocconsumer --save

usage:

Define a common context. Filename: RootContext.js

import ReactContext from 'react-context-hocconsumer';
export const defaultStore = {name:'pace'} 
const RootContext =  ReactContext(defaultStore) //Default values are optional
export default RootContext;
export const Provider = RootContext.Provider;
export const Consumer = RootContext.Consumer;

The parent component: The component that manages the context, the Provider entry.

import React, { PureComponent } from 'react';
import {Provider,defaultStore} from './RootContext';
import SubComponent from './SubComponent';
export default class ParentComponent extends PureComponent {

    state = {
        store: defaultStore, 
    }

    render() {
        return <Provider value={this.state.store}>  
            <SubComponent /> 
        </Provider>
    }
}

Basic usage, The context is mounted to the store by default

import React, { PureComponent } from 'react';
import {Consumer} from './RootContext';
@Consumer
export default class SubComponent extends PureComponent {
    render() {
        return <div>
            {this.props.store.name}
        </div>
    }
}

Resolve the context of the requirements to props

import React, { PureComponent } from 'react';
import {Consumer} from './RootContext';
@Consumer(context =>({
    name: context.name  
}))
export default class SubComponent extends PureComponent {
    render() {
        return <div>
            {this.props.name}
        </div>
    }
}
