Indexed Database API - Recommendation

http://www.w3.org/TR/IndexedDB/

Defines APIs for a database of records holding simple values and hierarchical objects (key/value).The database maintains indexes over records it stores. An application developer directly uses an API to locate records either by their key or by using an index. A query language can be layered on this API. An indexed database can be implemented using a persistent B-tree data structure.

Server-Sent Events - Proposed Recommendation

http://www.w3.org/TR/eventsource/

This specification defines an API for opening an HTTP connection for receiving push notifications from a server in the form of DOM events. The API is designed such that it can be extended to work with other push notification schemes such as Push SMS.

A possible alternative to websockets in some scenarios.

Node.js

Node.js: 2014 In Review

Node.js: 2014 In Review (cont)

io.js

http://iojs.org/

io.js is an npm compatible platform originally based on node.js.

How does it differ from node.js?

The project aims to continue development under an open governance model.

More io.js

From the State of io.js:

There have been 4 patch releases downloaded over 400K times.

In the lifetime of node.js™ there have never been more than 8 active committers. Last week Chris Dickinson onboarded 8 new committers to io.js with plans to bring on another round this week.

... you can expect io.js to be marked stable in March.

Some tasks outside of core development have already grown to the point that they necessitate their own project teams and committers.

Now io.js’ biggest problem is keeping up with the flood of contributors coming in, participating in every facet of the project. io.js isn’t just healthier than node.js™ today, it’s healthier than node.js™ ever was and this is only the beginning.

Start Thinking About...
