When using ESLint and TypeScript checkers together, ESLint checker only runs at startup

[mfisher87]

Describe the bug

When I start up my Vite dev server, ESLint and TypeScript both run.

When I change a file after this point, only TypeScript runs. It runs twice on each file change. My logs look like this:

  VITE v5.3.3  ready in 423 ms

  ➜  Network: http://172.21.0.2:5173/

Reproduction

My config:

    checker({
      typescript: {buildMode: true},
      eslint: {
        lintCommand: 'eslint . --ext ts,tsx --report-unused-disable-directives',
      },
    }),

I believe this is all that's needed to reproduce the behavior!

Expected behavior

ESLint and Typescript checkers run once each on every change

What's the version of typescript and eslint in your project?

Hey, thanks for taking a look at my issue! I'm on [email protected], [email protected], and [email protected]

This is the project in which I'm experiencing the symptoms (on the map branch): https://github.com/nsidc/aross-stations-ui Let me know if I haven't provided enough info, I'll be happy to work on a more complete reproduction.

I had the same issue (eslint run only once at startup) but apparently not for the same reason, I just mention it if it can help someone:
Don't forget the directory in the lintCommand attribute (in my case lintCommand: "eslint ." instead of lintCommand: "eslint").
