JavaScript project style linter

Install

$ npm install --save clinton

Usage

const clinton = require('clinton');
 
clinton.lint('/Users/sam/projects/clinton', {rules: {'license': ['error', 'MIT']}}).then(validations => {
    console.log(validations);
    /*
        [
            {
                ruleId: 'license',
                severity: 'error',
                message: 'License is not of type MIT (http://www.opensource.org/licenses/MIT).'
            }
        ]
    */
});

Instead of passing the rules as an option, you can also add them to your package.json file.

{
    "name": "foo",
    "license": "ISC",
    "clinton": {
        "rules": {
            "license": ["error", "MIT"]
        }
    }
}

Plugins

Everyone can create plugins or custom rules that can be validated with Clinton. The name of the plugin should be clinton-plugin-* where * is the name of the plugin.

Example

Let's create a clinton-plugin-file-exists rule that checks if the file provided as argument really exists.

'use strict';
module.exports = ctx => {
    const fileName = ctx.options[0];
 
    if (!ctx.files.includes(fileName)) {
        ctx.report({
            message: `File ${fileName} does not exist.`
        });
    }
};

You can also return a promise if you are performing asynchronous operations.

You can wrap this up in a project, publish it to npm and install it in every project where you want to check if a file in your project really exists.

{
    "name": "Unicorn",
    "description": "My unicorn package",
    "version": "1.0.0",
    "scripts": {
        "test": "clinton"
    },
    "devDependencies": {
        "clinton": "*",
        "clinton-plugin-file-exists": "1.0.0"
    },
    "clinton": {
        "plugins": [
            "file-exists"
        ],
        "rules": {
            "file-exists": ["error", "index.js"]
        }
    }
}

When running npm test, clinton will execute your plugin and will use index.js as the option argument. The first that is passed to the plugin, error in this example, indicates the severity of the error.
