Use a Git commit message template to write better commit messages

Using Git Commit Message Templates to Write Better Commit Messages

The always enthusiastic and knowledgeable mr. @jasaltvik shared with our team an article on writing (good) Git commit messages: How to Write a Git Commit Message. This excellent article explains why good Git commit messages are important, and explains what constitutes a good commit message. I wholeheartedly agree with what @cbeams writes in his article. (Have you read it yet? If not, go read it now. I'll wait.) It's sensible stuff. So I decided to start following the

Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Advanced example for manually updating subscriptions in response to props changes in an async-safe way
// This is an advanced example! It is not typically required for application code.
// If you are using a library like Redux or MobX, use the container component provided by that library.
// If you are authoring such a library, use the technique shown below.
// This example shows how to safely update subscriptions in response to props changes.
// In this case, it is important to wait until `componentDidUpdate` before removing a subscription.
// In the event that a render is cancelled before being committed, this will prevent us from unsubscribing prematurely.
// We also need to be careful about how we handle events that are dispatched in between
// `getDerivedStateFromProps` and `componentDidUpdate` so that we don't put stale values into the `state`.

Delivering H/2 Push Payloads To Userland

Background

One of the biggest missed opportunities thus far with HTTP/2 ("H/2") is that we are not yet able to sunset WebSockets in favor of H/2. Web Sockets and H/2 both support multiplexing messages bi-directionally and can send both textual and binary data.

Server Sent Events ("SSE"), by contrast, are not bi-directional (they're a "server-push-only" channel) and binary data cannot be sent easily. They are, however, very simple to implement. Adding to the menagerie of options, RTCPeerConnection can also be used to signal data to applications in a low-latency (but potentially lossy) way.

Because H/2 [does not support the handshake (upgrade) that WebSockets use to negotiate a connection](https://daniel.haxx.se/blog/2016/06/15/no-websockets-
