Middleware

You can use custom middleware by -m or --middleware option. E.g:

lightstatic -m ./some_middleware.js

The middleware file must export a function which accept three arguments: req for http request, res for http response and options for lightstatic bash command options.

If the function return false, lightstatic won't handle request and response any more.

/** some_middleware.js **/

const { URL } = require('url');
module.exports = async function(req, res, options) {
  if (req.url.startsWith('/__proxy/')) {
    /**
     * const proxy = ...  // do some actual proxy stuff
     * req.pipe(proxy).pipe(res);
     */
    res.end('proxed!');
    return false; // lightstatic won't handle request as middleware function return false
  }
  const u = new URL(req.url, 'http://host');
  const delay = u.searchParams.get('delay');
  if (delay) {
    console.log('delay', delay);
    await new Promise(resolve => setTimeout(resolve, Number(delay)));
  }
  // lightstatic will continue handle request and response
}
