How/where I can set eslint config file in spacemacs

Question

I have project with eslint already setup and I would like to use it in Spacemacs. Unfortunately Spacemacs seems to ignore .eslintrc.js file in project root.

I'm on Windows 10 ...

Can anyone help?

Answer 1

Spacemacs (and flycheck, the autocompletion plugin that interfaces with eslint) don't look for eslint configs, they delegate that to eslint itself. If you're getting this issue it means eslint itself is erroring out when it tries to load your project config.

Run eslint --print-config . from your project directory and resolve all errors it prints out, and that should fix it.

hmm. Thanks but this is not related with errors in configuration. I can run eslint from terminal and it work correctly. Same with other editors. Only Spacemacs with Flycheck seems to have problem. – Chow

Again, the most recent versions of Flycheck don't check for the config file, they run eslint --print-config in the current directory, and check the exit code. So if running eslint --print-config . in your project directory doesn't report any issues, then not sure what the problem is. – Romeliaromelle

I just removed all packages and installed them again. And now Flycheck works. :) – Chow

Answer 2

I'm running a mac setup, this is what worked for me:

assuming you've installed eslint, you can enable syntax checking in your ~/.spacemacs file

---

Begin by typing SPC f e d and uncommenting syntax-checking

;; spell-checking
syntax-checking

• resync your config by typing SPC f e R
• open a javascript file in your project, which should have an .eslintrc in its root
• type SPC e v

From here you can confirm that javascript-eslint is enabled and that an .eslintrc has been detected for your project.
