Maintainability, Sustainability

• Write code in strict mode by having 'use strict' at the top of your script file

  • Note that code imported in ES2015 is always interpreted as strict-mode

• Extract shared logic out into separate files, and use a module system so that you can require() as needed

• Keep credentials and other environment variables out of your code. See dotenv or similar approaches

• Consider keeping integration functions (e.g. network requests, libraries) separate from processing functions (e.g. transformations, data traversal) in order to make them easier to test

• Consider writing automated tests with one of the following test frameworks or similar: ava, jest, mocha, tape

• Lint your code for common mistakes and anti-patterns by using ESLint with its recommended rules at a minimum

Convenient HTTP Requests

Here are our favourite ways of making HTTP requests with JavaScript:

• browser: fetch() (built-in)

• Node.js: node-fetch (like browsers' fetch())

• both (isomorphic): got, request

Front-End

• use hash-based routing in Cordova / webview apps, and consider using hash-based routing for web apps, too
