Inconsistent output file between windows and ubuntu

[scp-r]

Hi there, I'm trying to bundle same code on windows and ubuntu, and use gulp-uglify to compress the output files. Most of the output files are identical (with the same checksum) but only one is different. Don't know if browserify has any guarantees for this kind of cross-platform consistency, but it might be an issue worth looking into.

Below is a minimal POC that I've found by constantly trying. My project relies on echarts@^4.2.1, and uses gulp to run browserify to generate the bundle and finally compress it through gulp-uglify. In most cases this process will produce the same files on different platforms (at least in my current project).

browserify-gulp-example.zip

The output is the same on Ubuntu and macOS, but not on Windows. The difference is only some digital labels (causing inconsistent order of modules):

From what I've tried, echarts/lib/component/axis/AxisView is causing this inconsistency. However, if I add bundle.require('echarts/lib/component/axis/AxisView'); after line 10 of gulpfile.js, the output becomes consistent.

Below is the content of gulpfile.js. All files are available in zip archives.

const gulp = require('gulp');
const browserify = require('browserify');
const source = require('vinyl-source-stream');
const uglify = require('gulp-uglify');
const rev = require('gulp-rev');

function buildMain() {
    let bundle = browserify({
        entries: './main.js',
    });
    // uncomment next line the output will be consistent.
    // bundle.require('echarts/lib/component/axis/AxisView');
    return bundle.bundle()
        .pipe(source('main.js'))
        .pipe(gulp.dest('./bundle'));
}

gulp.task('build', gulp.series(buildMain, (done) => {
    return gulp.src(`./bundle/*.js`)
        .pipe(uglify())
        .pipe(rev())
        .pipe(gulp.dest(`./dist/scripts`))
        .pipe(rev.manifest())
        .pipe(gulp.dest('./bundle'));
}));

main.js has only one line:

require('echarts/lib/component/axis/AxisView');

Environment:

• Node version: 16.14.2 on all platforms, installed via nvm and nvm-windows.
• OS version: Windows 11, Ubuntu 20.04 and macOS 12.3.
• npm version: 8.5.5 on all platforms.

BTW, the problem can also be reproduced by executing npx browserify main.js > bundle.js.

Did you figure this out?

Did you figure this out?

No, just cleared up issues that no one responded. I migrated all my build machines to ubuntu so this issue doesn't affect us anymore

I'd prefer to leave it open, if that's ok with you, in case anyone else runs into it.
