jasmine-istanbul-reporter/lib/file-system.js

Jasmine report plugin that scrapes test pages for istanbul coverage stats and writes them to a set of files for eventual conversion to LCOV, Cobertura, etc.

var fse = require('fs-extra');
var ArgumentError = require('./error').ArgumentError;

module.exports = {
    fs: fse,
    writeJsonToFile: function writeJsonToFile(objectToWrite, filePath, callback) {
        if (typeof objectToWrite !== 'object') return callback(new ArgumentError('must provide an object for writing'));
        if (typeof filePath !== 'string') return callback(new ArgumentError('must provide a valid file path'));

        this.fs.outputJsonSync(filePath, objectToWrite);
        return callback();
    }
};
