Copy & paste Put the code below in your app's `` or at the very end of the ``. HTML ```html ``` Make sure you include it on every page of your app, so that TalkJS's notification features work correctly. ## 2. Use NPM If you use a bundler for your client-side JavaScript, such as Webpack, Browserify or Parcel, you can use NPM to import TalkJS into your app: ```bash npm install talkjs --save # or, if you use yarn yarn add talkjs ``` In your code, in place that is loaded on every page, do: ```javascript const Talk = require('talkjs'); // or, if you use ES6 or TypeScript import Talk from 'talkjs'; ``` Our NPM package ships with TypeScript type definitions, which means you'll get auto-completion on certain editors (such as Visual Studio Code or Atom): ## TalkJS loads fast The core TalkJS SDK is small and loads asynchronously, so that your page load times aren't impacted. TalkJS is served from our global CDN to ensure fast load times across the globe.
