Auto-deploying built products to gh-pages with GitHub Actions

This is a set up for projects which want to check in only their source files, but have their gh-pages branch automatically updated with some compiled output every time they push.

A file below this one contains the steps for doing this with Travis CI. However, these days I recommend GitHub Actions, for the following reasons:

• It is much easier and requires less steps, because you are already authenticated with GitHub, so you don't need to share secret keys across services like you do when coordinate Travis CI and GitHub.
• It is free, with no quotas.
• Anecdotally, builds are much faster with GitHub Actions than with Travis CI, especially in terms of time spent waiting for a builder.

# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

React Element Factories and JSX

You probably came here because your code is calling your component as a plain function call. This is now deprecated:

var MyComponent = require('MyComponent');

function render() {
 return MyComponent({ foo: 'bar' }); // WARNING

func EncodeStreamingVideo(streamingFile io.Reader, request ShouldCanceler) (*os.File, error) {
  outputFilename := generateFilename("mp4")

  // Actually start the command.
  cmd := exec.Command("ffmpeg",
    // Read input from stdin.
    "-i", "-",
    // ... environment-specific ffmpeg options ...
    "-y", outputFilename)
