What is gulp-sourcemaps?

The gulp-sourcemaps package is a plugin for Gulp that allows you to generate source maps for your files. Source maps are files that map from the transformed source to the original source, enabling you to debug your code more easily by seeing the original source in your browser's developer tools.

What are gulp-sourcemaps's main functionalities?

Initialize Source Maps

This feature initializes the source map generation process. The `sourcemaps.init()` method is called before any transformations are applied to the files, and `sourcemaps.write('.')` writes the source maps to the same directory as the transformed files.

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');

gulp.task('default', function () {
  return gulp.src('src/**/*.js')
    .pipe(sourcemaps.init())
    .pipe(sourcemaps.write('.'))
    .pipe(gulp.dest('dist'));
});

Write Inline Source Maps

This feature writes the source maps inline within the transformed files. The `sourcemaps.write()` method without any arguments will embed the source map directly into the output file.

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');

gulp.task('default', function () {
  return gulp.src('src/**/*.js')
    .pipe(sourcemaps.init())
    .pipe(sourcemaps.write())
    .pipe(gulp.dest('dist'));
});

Custom Source Map Path

This feature allows you to specify a custom path for the source maps. The `sourcemaps.write('../maps')` method writes the source maps to a directory named 'maps' that is one level up from the output directory.

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');

gulp.task('default', function () {
  return gulp.src('src/**/*.js')
    .pipe(sourcemaps.init())
    .pipe(sourcemaps.write('../maps'))
    .pipe(gulp.dest('dist'));
});
