Concatenate files with npm as build tool

You can also use the power of the shell to do what you want:

"scripts": {
  "concat": "cat www/js/**/*.js > all.js"},

I am using concat-files

And I noticed there's also concatenate-files

Both are pretty simple.

Also note writing your own is pretty simple too:

var output = files.map((f)=>{
  return fs.readFileSync(f).toString();
}).join(';')

fs.writeFileSync('dist/bundle.js', output)

Yep, concat is gone. I was looking at this as well while moving away from gulp to pure node and found the package to be missing.

As an alternative I am now using buildify. Might be a slight overkill, but it works.

var buildify = require('buildify');
var files = [
    "./node_modules/moduleA/file1.js",
    "./node_modules/moduleB/file2.js",
];

buildify()
    .concat(files)
    .save("./dist/www/scripts/init.min.js");

try this

var concat = require('concat')    
concat(['a.css', 'b.css', 'c.css'], 'all.css')

and don't forget about npm install concat

By command use concat-glob-cli

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "concat": "concat-glob-cli -f path/to/**/*.js -o bundle.js",
    ...
 },
