What to use

Test runner: ava
React components testing: enzyme
Endpoint testing: express + supertest
Mocking framework: sinon
External dependencies mocking: proxyquire

Test cases

all the following examples are using ava syntax, but they may be easily adapted to mocha or tape as well

$ npm install --save babel-cli babel-preset-es2015
$ npm install --save-dev jasmine

.babelrc:

{
 "presets": ["es2015"]

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.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
