createProjectGraphAsync prevents program from finishing

[mpsanchis]

Current Behavior

The following command doesn't finish in a terminal:

node myscript.js

If myscript is (simplest use case I could create):

const {createProjectGraphAsync} = require("@nx/devkit");

createProjectGraphAsync().then(projects => console.log(`myapp name: ${projects.nodes['myapp'].data.name}`))

Expected Behavior

Code finishes execution and terminal can run other commands after.

2. Run it with node

Additional Information

Came up in a conversation with Caleb on discord

Is this possibly the same issue why nx daemon is disabled in ci? Jobs exit before the daemon exits?

[mortargrind]

Would having an option in the arguments to control Daemon usage without meddling with global project/workspace configuration acceptable?

[FrozenPandaz]

We have this flag. https://nx.dev/nx-api/devkit/documents/createProjectGraphAsync#parameters

It is called resetDaemonClient.

Though I will admit it is a weird name and it isn't well documented.

1. Would someone like to open a PR to document it better?
2. Do you have a better name in mind for it?

[mpsanchis]

I wouldn't mind adding some more documentation, but I am not sure I fully understand why the process I spawn gets stuck if the daemon client is not reset. What I understand from the nx docs is that the daemon is a process running in background, and other processes can communicate with it. I would expect that my process does:

1. Make a request to the daemon
2. Get the answer and log it
3. Exit

However I see that the flag is called resetDaemonClient and not resetDaemonServer, which makes me think that createProjectGraphAsync is spawning a client in a separate process, which does not end, and then my main process doesn't end because there is a child of his still alive. Am I correct? If this is correct, I could add this information somewhere, for sure :) I'm understanding Nx more with time, and it'd be a nice first contribution.
