How to merge js or css files into one on a clean node?

Question

Node.js

Gentlemen, I accidentally stumbled upon a topic about nodes and the work of a packager was described there, but on a clean node it is possible or how to combine a bunch of files of the same type into one?

Answer 1

Combine all *.js files into one:

var exec = require('child_process').exec;

exec("cat *.js > concat.js", function (error, stdout, stderr) {
    console.log('stderr: ' + stderr);
    console.log('stdout: ' + stdout);
    if (!!error) {
        console.error('exec error: ' + error);
    }
});
