# ngrok's web interface is HTML, but configuration is bootstrapped as a JSON

# Brittle as all get out--YMMV. If you're still reading, usage is:

APIs: the good, the bad, and the ugly

• Michele Titolo @micheletitolo
• Who's built, designed, and spec'd a lot of APIs
• Talk will focus on web APIs, but applies to many programmatic APIs, too

Documentation

• good: it exists (and bonus points if it's interactive: I/O Docs is one nice example)

// Example of mocking out global `fetch`

// Spec works using Jasmine (via Karma) and _either_ tsc or babel.

//     $ npm install --save-dev fetch-mock whatwg-fetch

// If using `tsc`, grab the type definitions as well:
//
//     $ typings --save --global dt~fetch-mock dt~whatwg-fetch
