Wrap you Node.js project code by "use strict"

README.md

##What is

Redefine global module with "use strict" wrapper for own code. This module doesn't touch node_modules code, because node_modules can be didn't compatibilite with "use strict" requirements

How to test:

node start_point.js

it show in console appear "It works!" (this message prints by my_own_code.js file)

But if invoke:

node my_own_code.js

it throw error

(function (exports, require, module, __filename, __dirname) { class ItWorks {
                                                              ^^^^^
SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

my_own_code.js

class ItWorks {
    static log() {
        console.log('It works!');
    }
}

ItWorks.log();

start_point.js

"use strict";
require('./use_strict_wrapper')(__dirname);
require('./my_own_code');

use_strict_wrapper.js

"use strict";

const Module = require("module");

module.exports = function(project_folder) {
    Module.originalWrap = Module.wrap;
    Module.wrapWithUseStrict = function(script) {
        return this.originalWrap(`"use strict";${script}`);
    };

    Module.prototype.originalLoad = Module.prototype.load;
    Module.prototype.load = function(filename) {
        const Module = this.constructor;

        Module.wrap = filename.indexOf(project_folder) !== -1 && filename.indexOf('node_modules') === -1?
            Module.wrapWithUseStrict :
            Module.originalWrap;

        return this.originalLoad(filename);
    };
};
