Eslint diagnostics isn't working in helix

[babucarr32]

For weeks now, I haven’t been able to get ESLint working in Helix. It was working fine before, but after I reset my computer and set everything up again, it stopped working.

As part of debugging, I tried using VS Code with the ESLint extension — to my surprise, it worked fine. Running ESLint directly from the terminal also lints the code and finds errors without any issues. I even downgraded my node, eslint, and helix versions, but the problem persisted.

Based on the logs, the LSP appears to be communicating with Helix, but no diagnostics are being returned.

Any help will be appreciated!

My node version

node --version
v20.19.4

My eslint-version version

eslint --version
v8.57.0

Helix version

hx --version
helix 25.07.1 (a05c151b)

Best ESLint + Prettier Setup

1. eslint.config.js

// eslint.config.js
import js from '@eslint/js'
import globals from 'globals'
import reactHooks from 'eslint-plugin-react-hooks'
import reactRefresh from 'eslint-plugin-react-refresh'
import tseslint from 'typescript-eslint'
import { globalIgnores } from 'eslint/config'

export default tseslint.config([
  globalIgnores(['dist']),
  {
    files: ['**/*.{js,jsx,ts,tsx}'],
    extends: [
      js.configs.recommended,
      tseslint.configs.recommended,
      reactHooks.configs['recommended-latest'],
      reactRefresh.configs.vite,
    ],
    languageOptions: {
      ecmaVersion: 2020,
      sourceType: 'module',
      ecmaFeatures: { jsx: true }, 
      globals: globals.browser,
    },
    rules: {
      'no-console': ['error', { allow: ['warn', 'error'] }],
    },
  },
])

2. languages.toml

[[language]]
name = "javascript"
formatter = { command = "prettier", args = ["--stdin-filepath", "file.js"] }
auto-format = true

[[language]]
name = "typescript"
formatter = { command = "prettier", args = ["--stdin-filepath", "file.ts"] }
auto-format = true

[[language]]
name = "javascriptreact"
formatter = { command = "prettier", args = ["--stdin-filepath", "file.jsx"] }
auto-format = true

[[language]]
name = "typescriptreact"
formatter = { command = "prettier", args = ["--stdin-filepath", "file.tsx"] }
auto-format = true

It’s a simple ESLint setup that enforces best practices and catches errors for JavaScript, TypeScript, and React.

Thank you for your answer, but this does not seem to address the problem.

Somehow it started working again, today.

What happened
I noticed that hover is not responsive in one my projects using with tsx files. Funnily, it works in different projects with tsx files.

helix_term::commands::lsp [ERROR] Error requesting hover: request 1 timed out

Anyway, I pulled from from helix, and rebuild it.
I reinstalled npm i [email protected]
And somehow the diagnostics started working again.
Wired!

The hover issue still persists though
