@jsweb/params

Simple JS module to parse/serialize HTTP query/params. Useful for Fetch API or AJAX requests.

See tests at https://params.jsweb.app

New in v4.0.0

Now, its a full ES module, there is no UMD or CommonJS version.

In modern JS development ES modules are the pattern, already supported in newer versions of Node.js and modern borwsers natively.

Backward compatibility is not a concern here. If you use a module bundler (like Webpack or Rollup) to transpile your code, the result will be compatible according to your setup.
