Watch A Directory And Run Mocha JS With ES Modules When Files Change
This is how I'm running Mochajs in watch mode with ES Modules:
mocha --watch --parallel
--parallel is based off this comment to a GitHub issue about
--watch not working by itself with ES Modules.
If you try to run
mocha --watch without
--parallel it produces errors like:
Error [ERR_REQUIRE_ESM]: require() of ES Module /file/path/file.mjs not supported. Instead change the require of /file/path/file.mjs to a dynamic import() which is available in all CommonJS modules.
(I think I've done the dynamic import stuff before in other projects, but haven't tried it with Mocha yet)
