Can't find build.log

[LeZuse]

Hi, you are totally correct both with the core concept and lacking documentation. :/ Sorry about that!
We generate build.log using gulp-webpack in our gulp task:

import fs from 'fs';
import gulp from 'gulp';
import gutil from 'gulp-util';
import webpack from 'gulp-webpack';
import revision from 'git-rev';

import configFactory from "./webpack-production.config.js";

const VERSIONS = ['editor', 'viewer'];

let running = 0;

function allFinishedCallback(callback) {
  running--;
  if (running < 1) { callback(); }
}

gulp.task('webpack', callback => {
  revision.short(rev => {

    VERSIONS.forEach(version => {
      gutil.log('Building version', version);

      const config = configFactory({
        revision: rev,
        // ...other props...
      }, version);

      running++;

      gulp.src('src/js/app.js')
        .pipe(webpack(config, null, (err, stats) => {
          if (!err) {
            fs.writeFileSync(`build.${version}.log`, stats.toString());
            console.log('Build', version, stats.hash, 'done.');
          }
        }))
        .pipe(gulp.dest('dist/assets/'))
        .on('end', allFinishedCallback.bind(this, callback));
    });
  })
});

Build log is basically the output of webpack build task:

Hash: c00ad65585e3907e0eaf
Version: webpack 1.12.12
Time: 250760ms
                                       Asset       Size  Chunks             Chunk Names

... and so on ...

I am planning to somehow get rid of the build hash dependency, but haven't found any easy way to do that yet.

[espenhogbakk]

Thanks for the reply. Just of curiosity, what do you use the git revision for in configFactory?

[LeZuse]

We bake it into the build as a constant. That way the runtime knows which version it is running.

@espenhogbakk Any luck with the setup?

[espenhogbakk]

Made it work, but required some hacking here and there.

[LeZuse]

Glad to hear! I will make some improvements soon as we have some new
requirements in our team.
