horizon-react

React bindings for rethinkdb/horizon. This package just fork from react-horizon, only adding a update method to previous package.

Installation

npm i -S horizon-react-extend

Usage

Currently, horizon-react exports two enhancers. Similarly to react-redux, you'll have to first wrap a root component with a Connector which will initialize the horizon instance and then subscribe to data by using subscribe.

Example Root component:

import { Connector } from 'horizon-react';
import store from './store';
import TodoList from './components/TodoList';
 
// If you don't pass a horizon client instance, Connector will
// automatically create one for you
export default () => (
  <Connector store={store}>
    <TodoList />
  </Connector>
);
 
// if you pass a horizon client instance, you have to .connect() before
// you pass the instance to Connector
export default () => (
  <Connector store={store} horizon={horizon}>
    <TodoList />
  </Connector>
);

Example Subscribed component:

import { subscribe } from 'horizon-react';
import Todo from './Todo';
 
// simple subscription to the collection "todos"
const mapDataToProps = {
  todos: (hz) => hz('todos')
};
 
const TodoList = (props) => (
  <ul>
    {props.todos.map( todo => <Todo {...todo} /> )}
  </ul>
);
 
export default subscribe({
  mapDataToProps
})(TodoList)

Advanced Subscribed component:

import { subscribe } from 'horizon-react';
import Todo from './Todo';
 
// simple subscription to the collection "todos"
const mapDataToProps = {
  todos: (hz, props) => hz('todos').limit(props.limit)
};
 
// you can connect to redux state too
const mapStateToProps = (state, props) => ({
  ui: state.checkedTodos
});
 
const TodoList = (props) => (
  <ul>
    {props.todos.map( todo => <Todo {...todo} /> )}
  </ul>
);
 
export default subscribe({
  mapDataToProps,
  mapStateToProps
})(TodoList)

FAQ

Does this work with React Native?

It should! If not, please create a new issue!

Can I access the Horizon instance in the child components?

Yes, you can either directly use context to access .horizon or just use subscribe()(MyComponent). subscribe will pass the Horizon instance from the context down to your component as a prop horizon.

Example:

import { subscribe } from 'horizon-react';
 
const AddTodoButton = (props) => (
  <button onClick={() => {
    props.horizon('todos').store({ text: 'A new todo item.' });
  }}>
    Add a todo item.
  </button>
);
 
export default subscribe()(AddTodoButton);
