@gulp-sourcemaps/identity-map

What is @gulp-sourcemaps/identity-map?

@gulp-sourcemaps/identity-map is a Gulp plugin that generates a source map for a file by assuming the file content is the result of a transformation. It is useful for cases where you want to generate source maps for files that have already been transformed by other tools.

What are @gulp-sourcemaps/identity-map's main functionalities?

Generate Source Maps

This feature allows you to generate source maps for JavaScript files. The code sample demonstrates how to use the @gulp-sourcemaps/identity-map plugin in a Gulp task to generate source maps for all JavaScript files in the 'src' directory and output them to the 'dist' directory.

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');
const identityMap = require('@gulp-sourcemaps/identity-map');

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

Other packages similar to @gulp-sourcemaps/identity-map

gulp-sourcemaps

gulp-sourcemaps is a Gulp plugin that allows you to generate source maps for various types of files. It provides more flexibility and options compared to @gulp-sourcemaps/identity-map, as it can be used with a variety of other Gulp plugins to generate source maps for different types of transformations.

gulp-uglify

gulp-uglify is a Gulp plugin that minifies JavaScript files. While its primary purpose is not to generate source maps, it can be used in conjunction with gulp-sourcemaps to generate source maps for minified files. This makes it a complementary tool to @gulp-sourcemaps/identity-map when working with minified JavaScript.

gulp-babel

gulp-babel is a Gulp plugin that transpiles ES6+ JavaScript to ES5 using Babel. It can be used with gulp-sourcemaps to generate source maps for the transpiled code. This makes it a useful tool for generating source maps for JavaScript files that have been transformed by Babel, similar to @gulp-sourcemaps/identity-map.

Gulp plugin for generating an identity sourcemap for a file.

Example

var identityMap = require('@gulp-sourcemaps/identity-map');

gulp.src(...)
  .pipe(sourcemaps.init())
  .pipe(identityMap()) // .js and .css files will get a generated sourcemap
  .pipe(sourcemaps.write())
  .pipe(gulp.dest(...))

API
