@webmodule/resolve
==================

A simple class to resolve es, cjs, or node modules.

Can be used with rollup, esbuild, swc, esmoduleserver, ...

Example with a rollup plugin:

``js
const Resolver = require('@webmodule/resolve');

function rollupModulesPrefix(root) {
if (!root) return;
const resolver = new Resolver({
node_path: 'node_modules', // this is the default
prefix: root
});
return {
name: "modulesPrefix",
async resolveId(source, importer) {
if (!source.startsWith(root)) return null; //
const obj = resolver.resolve(source, importer);
return obj.path;
}
};
}
`

see @webmodules/bundle for a more complete example.

* new Resolver({prefix = "/", root = "."})

The url is a url pathname.
