eslint-service

Installation: npm install --global eslint-service

Usage (Sublime Text):

• Install SublimeLinter through Package Control
• Install SublimeLinter-eslint through Package Control
• Open Preferences: SublimeLinter Settings through the command palette
• Configure like so:

{
  "linters": {
    "eslint": {
      "executable": "eslint-service",
      "args": "--rule no-trailing-spaces=off"
    }
  }
}

Notes

• Binds to localhost:2881 by default, can be configured by setting ESLINT_PORT and ESLINT_HOST environment variables
• Service worker sticks around for 15 minutes by default, can be configured by setting ESLINT_TIMEOUT environment variable (timeout in seconds)
• Only the particular command-line options (eslint --format json --stdin --stdin-filename) used by SublimeLinter-eslint, and a single --rule foo=off are currently supported, but it would be very easy to add additional support for other options, PRs welcome!
