A Guide to Functional Programming Lingo for JavaScripters

Functional programming gets a bad wrap about being too hard for mere mortals to comprehend. This is nonsense. The concepts are actually quite simple to grasp.

The jargon is the hardest part. A lot of that vocabulary comes from a specialized field of mathematical study called category theory (with a liberal sprinkling of type theory and abstract algebra). This sounds a lot scarier than it is. You can do this!

All examples using ES6 syntax. wrap (foo) => bar means:

function wrap (foo) {

To implement API authentication in KeystoneJS, you need the following:

For key based authentication

Middleware that validates the key in the request body or a header

For session based authentication

An endpoint that handles signin
An endpoint that handles signout

This is an example of how to scaffold API endpoints to list / get / create / update / delete Posts in a Keystone website.

It's a modification of the default project created with the yo keystone generator (see https://github.com/JedWatson/generator-keystone)

Gists don't let you specify full paths, so in the project structure the files would be:

routes-index.js        -->    /routes/index.js         // modified to add the api endpoints
routes-api-posts.js    -->    /routes/api/posts.js     // new file containing the Post API route controllers
