gulp-prepend

Simple Gulp plugin to prepend a string (e.g. license text) with gulp-sourcemaps support.

Installing

Install the plugin as development dependency:

npm install gulp-prepend --save-dev

Basic Usage

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

function prependString() {
    return src('./bundle.js')
        .pipe(prepend('/** \n* @version 0.1.0 \n*/'))
        .pipe(dest('./build'));
}

exports.prependString = prependString;

And with gulp-sourcemaps (example with browserify):

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

const browserify = require('browserify');
const source = require('vinyl-source-stream');
const buffer = require('vinyl-buffer');

function bundle() {
    return browserify({ debug: true, entries: './main.js' })
        .bundle()
        .pipe(source('bundle.js'))
        .pipe(buffer())
        .pipe(sourcemaps.init({ loadMaps: true }))
        .pipe(prepend('/** \n* @version 0.1.0 \n*/'))
        .pipe(sourcemaps.write('.'))
        .pipe(dest('./build'));
}

exports.build = bundle;
