ESLint config that dynamically generates globals from a .js file with constants

.eslintrc.js

var fs = require('fs');
var getGlobals = require('acorn-globals');

var globals = {
    angular: true,
    DashboardApp: true,
    inject: true
};

var constants = fs.readFileSync(__dirname + '/dna-webapp/app/appConstants.js', 'utf8').toString();
getGlobals(constants, {includeFileVars: true}).forEach(function (global) {
    globals[global.name] = true
});

module.exports = {
    "extends": ["eslint:recommended"],
    "env": {
        "node": true,
        "browser": true,
        "jasmine": true,
        "protractor": true
    },
    "globals": globals,
    "rules": {
        "semi": [2, "always"]
    }
};
