# Important Notes
The command to run the gui dev environment has been changed. Invoking the old command will print a message about that.
From now on, use `pnpm dev:gui2` in repository root.
Fixes#10197
# Important Notes
From now on, package installation will be using `pnpm install`. Installing it globally is fine for convenience, but it can also be used as `corepack pnpm install` without having to install anything other than node. For now, all other scripts are still invoked using `npm`, so we can still invoke them with usual `--workspace` setting. As far as I can tell that doesn't really have any other side effects and is identical as running the script through `pnpm run` in respective workspace project subdirectory.

Changelog:
- update: Ydoc starts with the language server on the `localhost:1234` by default. The hostname and ports can be configured by setting environment variables `LANGUAGE_SERVER_YDOC_HOSTNAME` and `LANGUAGE_SERVER_YDOC_PORT`
- update: by default `npm dev run` uses the node Ydoc server. You can control it with `POLYGLOT_YDOC_SERVER` env variable. For example,
```
env POLYGLOT_YDOC_SERVER='true' npm --workspace=enso-gui2 run dev
```
To connect to the Ydoc server running on the 1234 port (the one started with the language server)
⠀
```
env POLYGLOT_YDOC_SERVER='ws://127.0.0.1:1235' npm --workspace=enso-gui2 run dev
```
To connect to the provided URL. Can be useful for debugging when you start a separate Ydoc process.
- update: run `npm install` before the engine build. It is required to create the Ydoc JS bundle.
