easy to generate webpack module with custom object body

JsonModule.js

'use strict';

var NormalModule = require('webpack/lib/NormalModule');

function JsonModule(request, parser, body) {
    NormalModule.call(this, request.request, request.request, request.request, [], request.request, parser);
    this.body = body;
    return this;
}

JsonModule.prototype = Object.create(NormalModule.prototype);

JsonModule.prototype.build = function(options, compilation, resolver, fs, callback) {
    var _this = this;
    NormalModule.prototype.build.call(this, options, compilation, resolver, {
        readFile: function(filepath, callback) {
            var buffy = new Buffer(`module.exports = { ${_this.body} };`);
            callback(null, buffy);
        }
    }, callback);
};

JsonModule.prototype.constructor = JsonModule;
module.exports = JsonModule;
