✎Things I Wish Someone Had Told Me Sooner

TS Node

ts-node lets you run .ts files from the cli as if they were transpiled .js files.

Simply install it:

$ npm install -g ts-node
$ npm install -g typescript

And run a .ts file:

$ ts-node script.ts

Or use it as a REPL:

$ ts-node

Nodemon even supports it out of the box!
