Mashing up JavaScript
1 like1,099 views
This document discusses mashing up JavaScript applications. It covers topics like CORS and OAuth2 for API access, using local storage to store access tokens, templates with Mustache.js, and implementing real-time updates using WebSockets, ActivityStreams, and PubSubHubbub. Code examples are provided for building a JavaScript client that retrieves data from an API using OAuth2 authorization, renders content with templates, and allows posting new entries.
