Include external JavaScript file in Node-Gulp-Webpack build

Question

I have an app built with Node-Gulp-Webpack.

I have an external JavaScript file external.js that is not local to my app, but I want to be able to require it in my app. This file is on a path for which there is an environment variable named MY_PATH.

How can I include this external.js as-is in my build without making a Node module out of it?

So far, this does not work and doesn't return a useful error message:

var external = require(process.env.MY_PATH + '/external.js');

Are you require'ing this external file into a client side file, or in your nodejs app? — Cole Lawrence

Is process.env.MY_PATH being resolved correctly? What is the output of console.log(process.env.MY_PATH)? — Cole Lawrence

I created a env variable called MY_PATH set to a path and used require(process.env.MY_PATH) and it worked using the node REPL, it didn't work at first because I had to open a new cmd prompt. — Cole Lawrence

Use gulp-remote-src, the example:

var gulp = require('gulp');
var uglify = require('gulp-uglify');
var remoteSrc = require('gulp-remote-src');

gulp.task('remote', function() { 
    remoteSrc(['app.js', 'jquery.js'], {
        base: 'http://myapps.com/assets/',
    })
    .pipe(uglify())
    .pipe(gulp.dest('./dist/'));
})
