Description
@bradzacher and @JoshuaKGoldberg - hijacking OP to say:
We are currently investigating solutions to this with the TypeScript team: microsoft/TypeScript#35676, #1718, #2094, #6754
If you run into an OOM, please provide as much information as you can, including answering the following questions:
- Is your project open-source? (if yes - link please)
- Is your package a monorepo? If yes:
- Are you using lerna, or some other method?
- How many packages are in your monorepo?
- Do you have one
tsconfigper package, one at the root, or a mish-mash of both? - How interdependent is your codebase (i.e. are there lots of utility packages that are used by every package, or is it mainly packages with clear separations?)
- How do you build your project(s)?
- Is it via
tsc,webpack/rollup/etc, or a mish-mash of both?
- Is it via
- How many TS files are in your codebase?
- Approx how many lines of code are in your codebase?
- How many NPM dependencies do you have?
Also, please provide the following (you can leave the last two out if you're open source):
- A complete lint run output with the
DEBUG=*env variable set?DEBUG=* yarn lint- Feel free to censor the output filenames if you'd prefer, but try not to delete any lines.
- The tsconfig(s) that you pass via the
parserOptions.projectoption - Your
.eslintrc
The more information you provide, the easier it is for us to look into it and figure out root causes.
What code were you trying to parse?
A relatively huge code base with a lot of TypeScript (using project references), JavaScript and React. Unfortunately I can't give you a sample project because in my small demo projects it works. It only happens in that larger project that isn't open source. I also tried to disable @typescript-eslint/recommended-requiring-type-checking but that didn't work.
What did you expect to happen?
Not to run out of memory
What actually happened?
It runs out of memory.
