Node.js - CommonJS

Use browserify or webpack.


Use node, not bower module.

If you are using tools that support jsnext, like a rollup or JSPM, they will automatically select right module from the package.

With TypeScript

Install library/module using npm. Package bundles type definitions and if you are on TypeScript 2.0 or above tsc will access those automatically. If not, check your tsconfig.json file.
