  • Directions will be given after getting this envrionment set up

Testing

tsc and jest should be run in different terminal windows

yarn tsc --watch

yarn jest --coverage --watch

  • While not set up in this repo, it is possible to run two child processes in the same terminal with a package like concurrently: https://github.com/open-cli-tools/concurrently#readme

  • This will allow both tsc and jest to watch for file changes and run tests when changes are detected.

  • It is not necessary to run nodemon while running tests with jest in this case, as we are not using a server. However, if you are making changes to your typescript file, it is necessary to run tsc to compile on file changes.

Dev

yarn tsc --watch

yarn nodemon -w dist dist/ts_playground.js
  • Running these two commands in terminals will let tsc watch for changes to any file, and then nodemon will restart and run any compiled code from ts_playground.js
