Hello! I have been using nvim-lspconfig quite joyfully with solargraph (Ruby) as well as lua_ls. Love it!
However, I’m having trouble getting it to work with eslint. When I open an offensive file (one with linting errors), I don’t see anything! I need assistance debugging my setup and not sure where to turn next. Here is what I’ve looked at so far:
First, I can confirm via :LspInfo that the eslint client is attached to the buffer.
2 client(s) attached to this buffer:
Client: GitHub Copilot (id: 1, bufnr: [1])
# ...
Client: eslint (id: 2, bufnr: [1])
filetypes: javascript, javascriptreact, typescript, typescriptreact, vue
autostart: true
root directory: /Users/damon/Project/my-project
cmd: /Users/damon/.local/share/nvim/mason/bin/vscode-eslint-language-server --stdio
Second, if I use vim-dispatch to run eslint on the file (e.g., :Dispatch yarn eslint %) I can see the errors in the quickfix window. So the file has errors.
Third, if I run :EslintFixAll in the buffer, it actually does fix the offending file in the buffer correctly! So this part is working.
That’s as far as I’ve gotten. Any ideas on how to debug this?
