react2angular

The easiest way to embed React components in Angular 1 apps! (opposite of angular2react)

this version can be used with React 18 and probably up

Installation

# Using Yarn:
yarn add react2angular react react-dom prop-types

# Or, using NPM:
npm install react2angular react react-dom prop-types --save

Usage

1. Create a React component

import { Component } from "react";

class MyComponent extends Component {
  render() {
    return (
      <div>
        <p>FooBar: {this.props.fooBar}</p>
        <p>Baz: {this.props.baz}</p>
      </div>
    );
  }
}

2. Expose it to Angular

import { react2angular } from "react2angular";

angular
  .module("myModule", [])
  .component("myComponent", react2angular(MyComponent, ["fooBar", "baz"]));

Note: If you defined propTypes on your component, they will be used to compute component's bindings, and you can omit the 2nd argument:

...
  .component('myComponent', react2angular(MyComponent))

If propTypes are defined and you passed in a 2nd argument, the argument will override propTypes.

3. Use it in your Angular 1 code

<my-component foo-bar="3" baz="'baz'"></my-component>

Note: All React props are converted to AngularJS one-way bindings. If you are passing functions into your React component, they need to be passed as a function ref, rather than as an invokable expression. Keeping an existing AngularJS-style expression will result in infinite loops as the function re-evaluates on each digest loop.

Dependency Injection

It's easy to pass services/constants/etc. to your React component: just pass them in as the 3rd argument, and they will be available in your component's Props. For example:

import { Component } from "react";
import { react2angular } from "react2angular";

class MyComponent extends Component {
  state = {
    data: "",
  };
  componentDidMount() {
    this.props.$http
      .get("/path")
      .then((res) => this.setState({ data: res.data }));
  }
  render() {
    return (
      <div>
        {this.props.FOO}
        {this.state.data}
      </div>
    );
  }
}

angular
  .module("myModule", [])
  .constant("FOO", "FOO!")
  .component("myComponent", react2angular(MyComponent, [], ["$http", "FOO"]));

Note: If you have an injection that matches the name of a prop, then the value will be resolved with the injection, not the prop.
