React-based typeahead and typeahead-tokenizer
npm install react-typeahead> A typeahead/autocomplete component for React
react-typeahead is a javascript library that provides a react-based
typeahead, or autocomplete text entry, as well as a "typeahead tokenizer",
a typeahead that allows you to select multiple results.
For a typeahead input:
``javascript`
var Typeahead = require('react-typeahead').Typeahead;
React.render(
maxVisible={2}
/>
);
For a tokenizer typeahead input:
`javascript`
var Tokenizer = require('react-typeahead').Tokenizer;
React.render(
onTokenAdd={function(token) {
console.log('token added: ', token);
}}
/>
);

You will need npm to develop on react-typeahead. [Installing npm][4].
Once that's done, to get started, run npm install in your checkout directory.gulp
This will install all the local development dependences, such as and mocha
react-typeahead uses mocha for unit tests and gulp for running them. Large changes should
include unittests.
After updating or creating new tests, run npm run-script build-test to regenerate the
test package.
Once that's done, running the tests is easy with gulp:
`
> gulp test
[00:17:25] Using gulpfile ~/src/react-typeahead/gulpfile.js
[00:17:25] Starting 'test'...
․․․․․․․․․․․․․․․
15 passing (43ms)
[00:17:25] Finished 'test' after 448 ms
[00:17:25] Starting 'default'...
[00:17:25] Finished 'default' after 6.23 μs

Basically, fork the repository and send a pull request. It can be difficult to review these, so
here are some general rules to follow for getting your PR accepted more quickly:
- All new properties and exposed component function should be documented in the README.md
- Break your changes into smaller, easy to understand commits.
- Send separate PRs for each commit when possible.
- Feel free to rebase, merge, and rewrite commits to make them more readible.
- Add comments explaining anything that's not painfully obvious.
- Add unittests for your change if possible.
