Usage basic

Pass in your items as a prop to react-search. The items must be an array of objects with value and id, and any other props you may need, which will not be displayed. Check out the example for more info.

import Search from 'react-search'
import ReactDOM from 'react-dom'
import React, { Component, PropTypes } from 'react'

class TestComponent extends Component {

  HiItems(items) {
    console.log(items)
  }

  render () {
    let items = [
      { id: 0, value: 'ruby' },
      { id: 1, value: 'javascript' },
      { id: 2, value: 'lua' },
      { id: 3, value: 'go' },
      { id: 4, value: 'julia' }
    ]

    return (
      <div>
        <Search items={items} />

        <Search items={items}
                placeholder='Pick your language'
                maxSelected={3}
                multiple={true}
                onItemsChanged={this.HiItems.bind(this)} />
      </div>
    )
  }
}

ReactDOM.render( <TestComponent />, document.getElementById('root'))

Usage async

To load items async before running the search to filter results you can pass a function to the getItemsAsync prop which will be triggered to load the results each key change. An example below using the github api to search for repos. Check out the example for more info.

import Search from 'react-search'
import ReactDOM from 'react-dom'
import React, { Component, PropTypes } from 'react'

class TestComponent extends Component {

  constructor (props) {
    super(props)
    this.state = { repos: [] }
  }

  getItemsAsync(searchValue, cb) {
    let url = `https://api.github.com/search/repositories?q=${searchValue}&language=javascript`
    fetch(url).then( (response) => {
      return response.json();
    }).then((results) => {
      if(results.items != undefined){
        let items = results.items.map( (res, i) => { return { id: i, value: res.full_name } })
        this.setState({ repos: items })
        cb(searchValue)
      }
    });
  }

  render () {
    return (
      <div>
        <Search items={this.state.repos}
                multiple={true}
                getItemsAsync={this.getItemsAsync.bind(this)}
                onItemsChanged={this.HiItems.bind(this)} />
      </div>
    )
  }
}

ReactDOM.render( <TestComponent />, document.getElementById('root'))
