I’ve been working on code that works on Browser, Web Workers and NodeJS. In order to export my module, I’ve been writing ugly code like this one:
(function () { /* ... Code that defines MyModule ... */ var all; if (typeof self !== 'undefined') { all = self; // Web Worker } else if (typeof window !== 'undefined') { all = window; // Browser } else if (typeof global !== 'undefined') { all = global; // NodeJS } all.MyModule = MyModule; if (typeof module !== 'undefined') { module.exports = MyModule; } })(); |
var all;
if (typeof self !== ‘undefined’) {
all = self; // Web Worker
} else if (typeof window !== ‘undefined’) {
all = window; // Browser
} else if (typeof global !== ‘undefined’) {
all = global; // NodeJS
}
all.MyModule = MyModule;
if (typeof module !== ‘undefined’) {
module.exports = MyModule;
}
})();
One-line Solution
Guillaume Marty showed me that sink.js uses this as a replacement for self, window and global. I managed to add support for module.exports in a one-liner!
(function (global) { /* ... Code that defines MyModule ... */ global.MyModule = (global.module || {}).exports = MyModule; })(this); |
global.MyModule = (global.module || {}).exports = MyModule;
})(this);
I have been looking for this magic line for a long time, I hope it will be useful to you too 🙂
