Is it possible to use eventsource with Checkly?

Hi Iaroslav,

Thanks for your question! Currently we don't support custom imports of NPM packages, you can read more about why here: https://www.checklyhq.com/docs/runtimes/#why-cant-i-import-any-npm-package-or-other-3rd-party-dependencies

We often add new packages when we release new runtimes if the use case they unlock is valuable for a wider audience.

Could you expand on how you'd like to use eventsource and what it would allow you to do that you cannot with Checkly today.

Regards,
Rikard
