vscode-eslint-language-server does not work

[wparsonsheins-globality]

Summary

The eslint language server expects to be passed a workingDirectory but null was given.

Reproduction Steps

I tried this:

1. hx
2. Open a tsx file

I expected this to happen: The language server could spawn

Instead, this happened: The language server did not spawn

workingDirectory is not part of the LSP spec - this server is expecting it as a configuration option. You can provide configuration options with the config option in languages.toml like here

I tried adding the config property but the logs show workingDirectory is still null.

[[language]]
name = "tsx"
scope = "source.tsx"
injection-regex = "^(tsx)$" # |typescript
file-types = ["tsx"]
roots = []
language-server = { command = "vscode-eslint-language-server", args = ["--stdio"], language-id = "typescriptreact" }
indent = { tab-width = 4, unit = "  " }
config = { "workingDirectory" = "./" }

Experiencing the same issue, I have been digging within the vscode-eslint-language-server code and logged some stuff, it seems that no configuration is found for the workspace despite setting the config property in the TOML file.

Here is a minimal working configuration based on lspconfig but it requires a fix present in #2507:

[language-server.eslint]
command = "vscode-eslint-language-server"
args = ["--stdio"]

[language-server.eslint.config]
validate = "on"
experimental = { useFlatConfig = false }
rulesCustomizations = []
run = "onType"
problems = { shortenToSingleLine = false }
nodePath = ""

With these settings the eslint language server runs when opening a file without errors. Additional options like codeAction can be enabled.

It seems that there is an additional problem. It seems that vscode-eslint-language-server does not work well for monorepos on it's own. When you have eslintConfig setup in root's package.json, launching eslint in sub-package won't find the root's config. Since vscode-eslint-language-server stops looking for workspace directory as soon it finds any of project's folder indicators such as "package.json". "eslintignore" or "eslintrc". It can be seen in the source code here: https://github.com/microsoft/vscode-eslint/blob/cbb35d03497bb39043033defbad7fd80b2a89698/server/src/eslintServer.ts#L1093

Vscode and vim tend to work cos they provide some hacky work arounds to find workspace directory. In helix, without plugin management, I am not sure what can be done (apart of manually setting workingDirectory path to workspace's directory

@JeviScript I am working in a monorepo as well and having the same issue. Did you find a better solution to this problem in the meantime?
