RangeError: Maximum call stack size exceeded

[hikkyu]

Hi there!

I work on a very big monorepo, and I encountered an issue when I run these commands with the latest version (2.30.1):

npx knip --no-gitignore

As we have multiple workspaces also tried just in one workspace (around 1000 files to analyze):
npx knip --no-gitignore --workspace apps/fr-app --exports

But I got a Heap of memory then I tried

NODE_OPTIONS=--max-old-space-size=5120 npx knip --no-gitignore --workspace apps/fr-app --exports

Also tried without npx with script in the package.json

But in any case, I always get this error:

file:///<my-project-path>/node_modules/knip/dist/typescript/getImportsAndExports.js:120
                const results = visitor(node, options);
                                ^

Additional information: I didn't setup a knip config file, I used the default config only.

Does it ring a bell? Tell me if you need more information 🙂

No, doesn't ring a 🔔 unfortunately. Without a reproduction there isn't much I can see/do.

Most likely an infinite recursion and/or cyclic dependency.

[stackptr]

A variation of this error was caused in my project by a circular dependency. I was able to setup madge to analyze the dependency tree and fix the issue.

I wonder if there is anything useful that could be logged for debugging this scenario?

[webpro]

I've released v2.31.0 which might fix it (probably not, though).

Otherwise I'll need a reproduction.

Using --debug probably doesn't give that much, but might at least show where in the process and/or in which workspace Knip is currently running.

[webpro]

Closing this due to inactivity. Feel free to discuss further or open a new issue. Note that I'd need a reproduction.

I have the same issue on the newest version (2.40.0) - first I had an OoM, so I've added NODE_OPTIONS=--max-old-space-size=11776

now RangeError: Maximum call stack size exceeded 😢.

can't really give a repro, since it's a company project. I'll try to find out if there's a circular dependency, as mentioned above

Knip v4 is about to mitigate some of these issues: https://knip.dev/blog/slim-down-to-speed-up (you can install and try v4 canary today). Recently added --isolate-workspaces (in v3) which may also help in certain edge cases.
