A tool to test ESLint configurations against a set of git repos.

linto 💄

A tool to test ESLint configurations against a set of GitHub repos.

Installation

yarn global add linto
# or if you have time to spare
npm install -g linto

Usage

linto run -c config.json

where config.json has the following structure:

{
  "repos": [{
    "owner": "buildo",
    "name": "linto"
  }],
  "eslintConfig": {
    "rules": {
      "semi": "error"
    }
  }
}

You can also write the config file in YAML format:

repos:
  - owner: buildo
    name: linto
eslintConfig:
  rules:
    semi: error

Target paths

By default, linto checks the src and the web/src directories of each repo. This default can be overridden on a repo base:

{
  "repos": [{
    "owner": "buildo",
    "name": "someMonoRepo",
    "paths": ["thefrontend/src"]
  }]
}

Plugin support

You can include any ESLint plugin in the config, as long as it's available on npm.

If, for example, you provide the following config

{
  "plugins": ["whatever"],
  "rules": {
    "whatever/rule": 2
  }
}

then linto will try to retrieve eslint-plugin-whatever from npm and make it available to ESLint.

Cleanup

linto creates temporary directories during its execution (to clone repos, install plugins, etc) and it cleans up after itself. However, in case linto is stopped during its execution, some of the directories it created may not be deleted. In order to remove all linto's temporary directories, you can run

linto clean

You can also perform a dry run, using -n or --dry-run:

linto clean -n # don't delete anything, just print what would be deleted
