Usage

gulp 3.x

gulp.task('build', () => {
  gulp.src('./src/*.js')
    .pipe(unassert())
    .pipe(gulp.dest('./dist'));
});

gulp 4.x

const { src, dest } = require('gulp');
const unassert = require('gulp-unassert');

function build() {
  return src('./src/*.js')
    .pipe(unassert())
    .pipe(dest('./dist'));
}
exports.build = build;

custom unassert options

const { src, dest } = require('gulp');
const unassert = require('gulp-unassert');

function build() {
  return src('./src/*.js')
    .pipe(unassert({
      modules: [
        'assert',
        'assert/strict',
        'node:assert',
        'node:assert/strict',
        'invariant',
        'uvu/assert'
      ]
    }))
    .pipe(dest('./dist'));
}
exports.build = build;

Source maps

gulp 3.x

gulp-unassert can be used with gulp-sourcemaps to generate source maps for the transformed javascript code. Note that you should init gulp-sourcemaps prior to running the gulp-unassert and write the source maps after. gulp-unassert works well with some gulp plugins that supports gulp-sourcemaps.

const unassert = require('gulp-unassert');
const coffee = require('gulp-coffee');
const concat = require('gulp-concat');
const sourcemaps = require('gulp-sourcemaps');

gulp.task('build', () => {
  // compile, instrument then concatinate
  gulp.src('./src/**/*.coffee')
    .pipe(sourcemaps.init())
    .pipe(coffee({bare: true}))
    .pipe(unassert())
    .pipe(concat('bundle.js'))
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('./build'));
  // will write the source maps inline in the code
});

For more information, see gulp-sourcemaps.

gulp 4.x

In gulp 4, sourcemaps are built-in by default.

const { src, dest } = require('gulp');
const unassert = require('gulp-unassert');
const coffee = require('gulp-coffee');
const concat = require('gulp-concat');

function build() {
  return src('./src/*.coffee', { sourcemaps: true })
    .pipe(coffee({ bare: true }))
    .pipe(unassert())
    .pipe(concat('bundle.js'))
    .pipe(dest('./build'));
}
exports.build = build;
