Assist

Biome assist offers a series of actions (or rules) meant to improve code quality and DX of the users.

Contrary to linter rules, assist actions are meant for editors and IDEs, and they can include things like sorting of properties or fields, simplification of binary expressions and more. The assist has 3 actions.

Assist actions are very close LSP code actions in semantics.

Biome assist is enabled by default. In the following example, you can enable the assist and enable the action useSortedKeys:

1
{
2
    "assist": {
3
        "enabled": true,
4
        "actions": {
5
            "source": {
6
                "useSortedKeys": "on"
7
            }
8
        }
9
    }
10
}

Enforce assist actions via CLI

Assist actions can be enforced via CLI via check command:

1
npx @biomejs/biome check

1
yarn biome check

1
pnpm biome check

1
bunx biome check

1
deno run -A npm:@biomejs/biome check

However, the check is meant for running multiple tools at once, so if you want to check only the assist actions, you should run:

1
npx @biomejs/biome check --formatter-enabled=false --linter-enabled=false --organize-imports-enabled=false

1
yarn biome check --formatter-enabled=false --linter-enabled=false --organize-imports-enabled=false

1
pnpm biome check --formatter-enabled=false --linter-enabled=false --organize-imports-enabled=false

1
bunx biome check --formatter-enabled=false --linter-enabled=false --organize-imports-enabled=false

1
deno run -A npm:@biomejs/biome check --formatter-enabled=false --linter-enabled=false --organize-imports-enabled=false
