react-typeahead

React component to allow fuzzy searching of a list for a value as you type. Exports a commonjs module that can be used with webpack. Source is in ES6 and is compiled down to ES5 using Babel.

Usage

ES6/JSX (Recommended)

The component is written using ES6/JSX therefore Babel is recommended to use it. The below example is based on using webpack and babel-loader.

import React from 'react';
import Typeahead from 'ship-components-typeahead';

export default class BasicExample extends React.Component

  render() {
    return (
      <Typeahead
        options={[
          {
            value: 'One'
          },
          {
            value: 'Two'
          },
          {
            value: 'Three'
          }
        ]}
        extract={(item)=>item.label}
        value={this.state.value}
        onChange={this.handleChange} />
    );
  }
}

Examples and Development

More examples can be found in the examples/ folder. A development server can be run with:

$ npm install
$ npm start

which will live reload any changes you make and serve them at http://localhost:8080.

Webpack Configuration

This module is designed to be used with webpack but requires a few loaders if you are pulling the source into another project.

$ npm install webpack babel-loader css-loader style-loader postcss-loader extract-text-webpack-plugin postcss-nested postcss-color-hex-alpha postcss-color-function postcss-calc postcss-simple-vars autoprefixer --save-dev

Below are is a sample of how to setup the loaders:

/**
 * Relevant Webpack Configuration
 */
{
  [...]
  module: {
    loaders: [
      // Setup support for ES6
      {
        test: /\.(jsx?|es6)$/,
        exclude: /node_modules/,
        loader: 'babel'
      },
      // Setup support for CSS Modules
      {
        test: /\.css$/,
        loader: ExtractTextPlugin.extract('style-loader', 'css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]!postcss-loader')
      }
    ]
  },
  plugins: [
    // Extract the css and put it in one file. Path is relative to output path
    new ExtractTextPlugin('../css/[name].css', { allChunks: true })
  ],
  // CSS Modules
  postcss: [
    require('postcss-nested'),
    require('postcss-simple-vars') {
      variables: {
        'base-grid-size' : '4px',
        'primary-color' : '#5e8aaa',
        'accent-color' : '#38b889',
        'warning-color' : '#d43c36',
        'success-color' : '#50a111',
        'primary-font-color': '#333',
        'inverse-font-color': '#fff',
        'primary-background-color' : '#fff'
      }
    },
    require('postcss-color-hex-alpha'),
    require('postcss-color-function'),
    require('postcss-calc'),
    require('autoprefixer')
