export default defineConfig({
    installOnLockChange: true,
    commitMessage: {
        pattern: "^ID-[0-9]+: .+",
        message: pc => pc.red("Branch must look like this ID-<number>: <message>"),
    },
    preCommit: ["npm run test"],
    staged: {

API Reference

Install on lock change

Install dependencies on lock file change. Uses git-install-hook under the hood. Installs automatically by default, but can be a prompt. Will run on branch change and after a merge.

• type: boolean | object
• default: false
• command: installOnLockChange
• hooks: post-checkout, post-merge

{
    "installOnLockChange": {
        "prompt": true,
        "installation": "show",
        "noText": false
    }
}

• prompt: boolean - prompt before installing
• installation: show | hide | spinner - show or hide the installation output
• noText: boolean - hide the text

Branch name

Validate branch name.

• type: boolean | object
• default: false
• command: branchName
• hooks: pre-commit

{
    "branchName": {
        "pattern": "^feature/.+",
        "message": "Branch name must start with 'feature/'"
    }
}

• pattern: string - regex pattern
• message: string | function - error message

The error message can be a string or a function that returns a string. It gets the pc object as parameter. This is piccocolors and can be used to style the text.

{
    "branchName": {
        "pattern": "^feature/.+",
        "message": pc => pc.red("Branch name must start with 'feature/'")
    }
}

Commit message

Validate commit message. Will run on commit-msg hook. If staged is enabled, it will run before the staged commands by moving the staged commands to the commit-msg hook.

• type: boolean | object
• default: false
• command: commitMessage
• hooks: commit-msg

{
    "commitMessage": {
        "pattern": "^ID-[0-9]+: .+",
        "message": "Branch must look like this ID-<number>: <message>"
    }
}

• pattern: string - regex pattern
• message: string | function - error message

The error message can be a string or a function that returns a string. It gets the pc object as parameter. This is piccocolors and can be used to style the text.

{
    "commitMessage": {
        "pattern": "^ID-[0-9]+: .+",
        "message": pc => pc.red("Branch must look like this ID-<number>: <message>")
    }
}

Staged

Run commands on staged files. Defaults to run on pre-commit, but will run on commit-msg if any feature that checks the commit message is enabled (commitMessage or enforceConventionalCommits). This is because the validation needs to run before running the commands.

• type: false | object
• default: false
• command: staged
• hooks: pre-commit, commit-msg

{
    "staged": {
        "*": "npm run format",
        "*.{ts,js}": "npm run lint"
    }
}

The key is a minimatch pattern. The value is a command to run. If no / is used in the name, it will match the file name even if it is in a subdirectory. If / is used, it will match the whole path.

Prevent commit

Prevent commits on certain branches.

• type: false | string | string[]
• default: false
• command: preventCommit
• hooks: pre-commit

{
    "preventCommit": ["main", "master", "develop"]
}

Sync before push

Sync (pull) before push. Will not sync if force push.

• type: boolean
• default: false
• command: syncBeforePush
• hooks: pre-push

{
    "syncBeforePush": false
}

Enforce conventional commits

Enforce conventional commits. If staged is enabled, it will run before the staged commands by moving the staged commands to the commit-msg hook.

• type: boolean
• default: false
• command: enforceConventionalCommits
• hooks: commit-msg

{
    "enforceConventionalCommits": true
}

No todos

Prevent commits with TODOs in comments.

• type: boolean
• default: false
• command: noTodos
• hooks: pre-commit

{
    "noTodos": true
}

Test changed

Run tests on changed files. Supports for jest and vitest.

• type: boolean
• default: false
• command: testChanged
• hooks: pre-commit

{
    "testChanged": true
}

Custom hooks

Any custom hook can be added. For example, the pre-commit hook can be added using camelCase preCommit as key and commands as value. This works for any valid hook.

• type: false | string | string[]
• default: false

{
    "preCommit": ["npm run test"]
}
