Feature request: in expanded mode, update only every N seconds

[dko-slapdash]

There is no sense to show 1%, 2%, 3%, ... every millisecond when the total build time is, like, 20 seconds. What I propose instead is to suppress output for N seconds (configurable, like, 5 seconds) in between printing the steps.

This would dramatically reduce the amount of output in CI or in docker-compose environment with multiple containers.

(The very 1st line and the very last line would ideally be shown independently of N.)

...BTW, this is an ad-hoc code I just wrote for similar purposes, FYI

const throttle = require("lodash/throttle");
const webpack = require("webpack");

class ThrottledWebpackProgressPlugin extends webpack.ProgressPlugin {
  show(percentage, message, modules, _, file) {
    console.log(
      (percentage * 100).toFixed() +
        "% " +
        message +
        (modules ? ": " + modules : "") +
        (file
          ? ": ..." +
            file.replace(/^.*?((?:\/([^/]+)){1,3})$/, (_, name) => name)
          : "")
    );
  }

  constructor(delay) {
    const throttled = throttle(
      (percentage, ...args) => {
        if (!percentage) {
          setTimeout(() => this.show(percentage, ...args), 10);
        } else {
          this.show(percentage, ...args);
        }
      },
      delay,
      { leading: true, trailing: false }
    );
    super(throttled);
  }
}

module.exports = ThrottledWebpackProgressPlugin;
