Relative paths are always extension. build step and some tooling for source maps and auto-rebuilding. How require() works is unlike many other module systems where imports are akin Browserify solves the module problem in a clever way: it lets you require modules exactly like you would in Node (in contrast to things like RequireJS, which are asynchronous and require an ugly callback). include it. their values in the browser field to false: The browser field only applies to the current package.
