[💡 Feature]: ESM Compatibility

[christian-bromann]

Is your feature request related to a problem?

Our goal for v8 is to deliver WebdriverIO packages for more than just Node.js environments. As a first step, let's make WebdriverIO ESM compatible (for that see v8 branch). Next is to make all community packages compatible by moving them to ESM otherwise they can't be used in v8. The packages owned by this community are tracked here:

• Transition package from CJS to ESM webdriverio-community/wdio-vscode-service#21
• Transition package from CJS to ESM webdriverio-community/wdio-intercept-service#310
• Transition package from CJS to ESM webdriverio-community/wdio-geckodriver-service#33
• Transition package from CJS to ESM webdriverio-community/wdio-safaridriver-service#6
• Transition package from CJS to ESM webdriverio-community/wdio-electron-service#35
• Transition package from CJS to ESM webdriverio-community/wdio-rerun-service#36
• Transition package from CJS to ESM webdriverio-community/wdio-chromedriver-service#78
• Transition package from CJS to ESM webdriverio-community/wdio-teamcity-reporter#31
• Transition package from CJS to ESM webdriverio-community/wdio-video-reporter#74
• Transition package from CJS to ESM webdriverio-community/wdio-cucumberjs-json-reporter#96
• Transition package from CJS to ESM webdriverio-community/wdio-edgedriver-service#5
• Transition package from CJS to ESM selenium-standalone#678
• Transition package from CJS to ESM wdio-wait-for#160

Describe the solution you'd like.

Make sure that all packages are exported and published in way to be used using CJS and ESM.

‼️ Attention ‼️

Anyone who likes us to support in this effort, just pick one of the packages above and help transform them into ESM. You can follow this example commit to get a sense of what needs to be changed. Also this: https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c is a good resource.

Updates

• 2022/07/05: it seems that the best tool to compile a hybrid modules is unbuild, I am currently adding this build step to the v8 branch - the only problem is what to do with modules that only support ESM
• 2022/07/07: it turns out that there is absolutely no need to transpile WebdriverIO packages into CJS. When using the testrunner we can dynamically import the cli as ESM module and for the webdriverio, webdriver and devtools packages we can just provide a CJS shim and import the ESM version too.

With e970be9 we finalised the ESM transition of the core modules. It is not required for services and reporters to transition to ESM before the v8 release. Therefor we can close this and mark it as done 🎉

Well done !
Any chance to see it released under a "next" channel, so we can start playing with it ?

Over the next days once the v8 build is green.
