Migrate CodeceptJS to ESM (Top-level await)

[danielhelen]

What are you trying to achieve?

I need to use top-level await to retrieve config from AWS and other APIs but CodeceptJS seems completely incompatible with ES modules. Top-level await is simply not possible in CommonJS. Are there any plans to support ES modules?

What do you get instead?

If you set "type": "module" in package.json you get this error:

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/REDACTED/config/codecept.conf.js from /Users/REDACTED/node_modules/codeceptjs/lib/config.js not supported.
Instead change the require of codecept.conf.js in /Users/REDACTED/node_modules/codeceptjs/lib/config.js to a dynamic import() which is available in all CommonJS modules.

@danielhelen at this moment this means to rewrite CodeceptJS completely and I don't think we have enough resources to handle this task.

Actually we can try this codemod, which can make migration faster
