Node

Memory Allocation

NODE_OPTIONS=--max-old-space-size=4096 node xyz.js

REPL

The node REPL ("Read Evaluate Print Loop") can be started by simply running node. This is both a great way to explore the language (e.g. verify what a given method returns) and explore installed / scoped modules. For the latter, you can type module from the REPL prompt to see the contents of the module object. Specically note the paths. If the module you want to create an instance of exists here you'll be able to create an instance of it, e.g. const moment = require('moment'). More detail here.

Handling Async

At a console (Chrome or REPL) you'll be able to handle async / await via the following...

(async function(){ console.log(await x.list()) })();

Getting current module version number

node -p "require('./package.json').version"
