🐛 Biome Linting Runs in Projects Without Configuration or Dependency When VSCode Extension is Enabled

[poteboy]

VS Code version

1.92.2

Extension version

2.3.0

Biome version

1.8.3

Operating system

• Windows
• macOS
• Linux

Description

The Biome linter runs on projects where it is not configured or installed. Specifically, Biome executes linting even when:

• The project’s package.json does not include a Biome dependency.
• There is no biome.json or any other configuration file related to Biome in the project.
• Biome VSCode Extension is enabled, and Biome Binary may be globally installed.

Steps to reproduce

1. Open a project in VSCode where Biome is not listed as a dependency in package.json.
2. Ensure that there is no biome.json or similar configuration in the project.
3. Confirm that the Biome is enabled (Biome 1.8.3 (bundled) as shown in the screenshot).
4. Notice that Biome still runs linting on files (e.g., showing errors such as "This else clause can be omitted...").

Expected behavior

Biome should not run linting in projects unless explicitly installed or configured within the project settings or dependency files.

Does this issue occur when using the CLI directly?

I have the same problem, sometimes I open a project that uses ESLint or other linter but Biome keeps showing errors and as there is no biome configuration it shows all recomended errors

Switching to the pre-release version solves this issue for me. (Please refer to biomejs/biome#1630)

Hope the support of multi-folder workspaces to be released soon!

I think this will be resolved by the pre-release of v3, could you try that?

Set true to the biome.requireConfigFile: https://deploy-preview-974--biomejs.netlify.app/reference/vscode/#biomerequireconfigfile

There is still an issue i am facing when there is an biome extension installed but no biome json file is there in the repo, still the biome is showing those as errors. I dont want it as in this repo i have already prettier and eslint configured. I am using biome extension version 1.9.2

@kotasudhakar did you follow the conversation? Did you try the pre-release with the new extension configuration?

If so, then please create a reproduction and open a new issue

I was looking for a solution to this same issue and tried the latest pre-release (v2024.10.204580). When I add "biome.requireConfigFile": true to my user settings.json file, I get the following dialog when I open a JS file:
