Getting Started

Biome Resolution

The plugin tries to use Biome from your project’s local dependencies (node_modules/.bin/biome). We recommend adding Biome as a project dependency to ensure that NPM scripts and the extension use the same Biome version.

You can also explicitly specify the biome binary the extension should use by configuring the Biome CLI Path in Settings->Language & Frameworks->Biome Settings.

Biome Config resolution

In Automatic Biome configuration mode, the plugin will look for a biome configuration file upwards from the current file. If it doesn't find one, it will stop LSP server. There are several reasons to behave like this:

1. In IDEA with multiple projects in one code base it sound reasonable to disable LSP server if there is no biome configuration file in the project.
2. In multi-root workspace, we should run biome from proper working directory, so that include and exclude paths are resolved correctly.
3. As currently LSP server proxy doesn't provide option to work with multiple configs, we should provide path to the biome configuration file and restart LSP server once active file is changed.

Biome CLI Path

This setting overrides the Biome binary used by the plugin.

Enabling Code Formatting

To enable formatting, open Biome settings and enable LSP-based Code Formatting. This feature allows you to format code using the designated hotkey (⌥⇧⌘+L or Ctrl+Alt+L).

If you want to format code on save, navigate to Actions on Save settings and enable Reformat Code, specifying the desired file types.

Supported IDEs

This plugin is currently supported in the following IDEs:

Usage

Biome CLI comes with many commands and options, so you can use only what you need.

Apply code fixes by either hovering over the relevant section and selecting the suggested fix, pressing ⌥+⏎(Option+Enter) or Alt+Enter.

To reformat your code, use the keyboard shortcut ⌥⇧+⌘+L or Ctrl+Alt+L. Alternatively, you can configure your IDE to format code automatically on save for a seamless coding experience.
