I have some problem with source code........

in ‘./src/tools/start.js’

  let handleBundleComplete = async () => {

  //I don't know what this assign operation means ?
  handleBundleComplete = stats => !stats.stats[1].compilation.errors.length && runServer();

  const server = await runServer();
  const bs = browserSync.create();

  bs.init({
    ...isDebug ? {} : { notify: false, ui: false },

    proxy: {
      target: server.host,
      middleware: [wpMiddleware, hotMiddleware],
      proxyOptions: {
        xfwd: true,
      },
    },
  }, resolve);
};

bundler.plugin('done', stats => handleBundleComplete(stats));

Is syntax like this ?

let handleBundleComplete = async ( ) => { handleBundleComplete = (...) => {...} do something.. }

@weishijun14 Oh got it!

When it is run for the first time it does some extra stuff:

const server = await runServer();
  const bs = browserSync.create();

  bs.init({
    ...isDebug ? {} : { notify: false, ui: false },

    proxy: {
      target: server.host,
      middleware: [wpMiddleware, hotMiddleware],
      proxyOptions: {
        xfwd: true,
      },
    },
  }, resolve);

For 2nd, 3rd,… it is overridden to

handleBundleComplete = stats => !stats.stats[1].compilation.errors.length && runServer();

@almeynman I found it, call Lazy loading function…
