Switch to .cjs for package.json main

[ViktorQvarfordt]

The problem I am facing
Yarn pnp is not compatible with ESM.

The solution I would like
Change package.json files like so:

-  "main": "dist/hocuspocus-server.esm.js",
+  "main": "dist/hocuspocus-server.cjs",

Additional context
I couldn't open a PR (cannot push a branch or fork the repo). But I attach a diff for convenience. diff.txt

Thanks! We decided to go with ECMAScript modules only. Read more about the reasoning here:

Also, the linked comment has interesting insights, too:

We know that this can causes issues in some setups (older Node versions, or Yarn pnp), but want to build a new package on a modern foundation. Maybe you can work around this in some way, for example with a separate project setup.

I see, that make sense. I found how to patch the package using yarn patch. With that we can still keep the code in our yarn workspaces setup. Closing this issue but leaving some additional notes here for future reference if someone else searches for this and finds this issue:

yarn add @hocuspocus/server
yarn patch @hocuspocus/server
# edit relevant files (see output of yarn patch above) as described in the first post
yarn patch-commit /private/var/folders/[generated-path] > hocuspocus-server.patch
# update package.json dependency in your yarn package to look something like this:
#  "@hocuspocus/server": "patch:@hocuspocus/server@^1.0.0-alpha.69#./hocuspocus-server.patch",

Oh, that’s a great solution. Thanks for sharing!
