Like an Event, an Observable is a sequence of values that a data producer pushes to the consumer. However unlike an Event, an Observable can signal to a listener that it has completed, and will send no more data.
Querying Arrays only gives us a snapshot. By contrast, querying Observables allows us to create data sets that react and update as the system changes over time. This enables a very powerful type of programming known as reactive programming.
Disposing of a Subscription object unsubscribes from the event and prevents memory leaks. Disposing of a subscription is the asynchronous equivalent of stopping half-way through a counting for loop.
If we convert Events to Observable Objects, we can use powerful functions to transform them.
Earlier this year Facebook open sourced its React based rich text editing framework Draft.js. At Facebook it powers status updates, comments & notes. Others used it to build editors matching Medium’s experience.
Together with a whole team of open source contributors I built a plugin architecture on top of Draft.js. In this talk I walk you through the existing plugins and show how you can build your own feature-rich text editor for the web with only a handful lines of code. 🤓

In this gist I would like to describe an idea for GraphQL subscriptions. It was inspired by conversations about subscriptions in the GraphQL slack channel and different GH issues, like #89 and #411.
At the moment GraphQL allows 2 types of queries:
query
mutation
Reference implementation also adds the third type: subscription
. It does not have any semantics yet, so here I would like to propose one possible semantics interpretation and the reasoning behind it.
2015-01-29 Unofficial Relay FAQ
Compilation of questions and answers about Relay from React.js Conf.
Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.
Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).
Locate the section for your github remote in the .git/config
file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/*
to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
