Usage

If you don’t have a .lintstagedrc.js, we will create the file for you after installing @anolilab/lint-staged-config.

If you already have a .lintstagedrc.js, then you can extend the .lintstagedrc.js, with @anolilab/lint-staged-config.

Note: If the script detects an existing .lintstagedrc.js file, it will not overwrite it.
Note: It can happen that the postinstall script don't run, then you have to add the .lintstagedrc.js manually.

The content of the .lintstagedrc.js should look like this:

const config = require("@anolilab/lint-staged-config");

module.exports = {
    ...config,
};

Config

You can configure @anolilab/lint-staged-config options with your package.json file.

Add this property to your package.json:

{
    anolilab: {
        "lint-staged-config": {
            // ...options
        },
    },
}

typescript

Type: object

Options:

exclude - Exclude files from tsc linting. Provide the path to the tsconfig.json file.
- Type: string[]
- Default: []

Example using package.json:

{
    "anolilab": {
        "lint-staged-config": {
            "typescript": {
                // ...options
            }
        }
    }
}

- Type: string
"fix-type"
- Type: string[]
"max-warnings"
- Type: number | string | false
rules - Override rules from eslint config.
- Type: string[]

Example using package.json:

{
    "anolilab": {
        "lint-staged-config": {
            "eslint": {
                // ...options
            }
        }
    }
}

Configuration

The default configuration, automatically adds the following linting and formatting tools, if the needed dependencies are installed.

All this tools configuration are exported at @anolilab/lint-staged-config/group/... and can be used to extend your configuration, without including the auto config.

Husky

If you want to use husky to run the lint-staged script, you can use the following configuration.

Adding the following script to your root package.json file makes it easier to run the husky command:

pnpm pkg set scripts.prepare="is-ci || husky install || exit 0"

For npm users, replace pnpm with npm in the above command.

This script will install husky only if it is not running in a CI environment.

After that you can find a .husky folder in your root directory, with a pre-commit (if not please create it) file.

The file content can look like this:

#!/bin/sh

. "$(dirname "$0")/_/husky.sh"

# The hook should exit with non-zero status after issuing
# an appropriate message if it wants to stop the commit.

echo --------------------------------------------
echo Starting Git hook: pre-commit

pnpx lint-staged --verbose --concurrent false

echo Finished Git hook: pre-commit
echo --------------------------------------------

Our package includes a postinstall script to automatically add the pre-commit, common.sh, prepare-commit-msg hooks to your.husky` folder.

Note: It can be that the postinstall script don't run, then you have to add the hooks manually.

If commitzen is installed, the prepare-commit-msg hook with predefined content will be added to your .husky folder.
