Consider opening the file directly, to avoid race conditions: const fs = require(‘fs’); fs.open(‘foo.txt’, ‘r’, function (err, fd) { // … }); Using fs.existsSync: if (fs.existsSync(‘foo.txt’)) { // … } Using fs.stat: fs.stat(‘foo.txt’, function(err, stat) { if (err == null) { console.log(‘File exists’); } else if (err.code === ‘ENOENT’) { // file does not exist … Read more
And what about: var myModule = require.main.require(‘./path/to/module’); It requires the file as if it were required from the main js file, so it works pretty well as long as your main js file is at the root of your project… and that’s something I appreciate.
app.use() is intended for binding middleware to your application. The path is a “mount” or “prefix” path and limits the middleware to only apply to any paths requested that begin with it. It can even be used to embed another application: // subapp.js var express = require(‘express’); var app = modules.exports = express(); // … … Read more
Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with ‘npm users’ but … Read more

You can have multiple registries for scoped packages in your .npmrc file. For example: @polymer:registry=<url register A> registry=http://localhost:4873/ Packages under @polymer scope will be received from https://registry.npmjs.org, but the rest will be received from your local NPM.
It can be done via https and oauth or ssh. https and oauth: create an access token that has “repo” scope and then use this syntax: “package-name”: “git+https://<github_token>:x-oauth-basic@github.com/<user>/<repo>.git” or ssh: setup ssh and then use this syntax: “package-name”: “git+ssh://git@github.com:<user>/<repo>.git” (note the use of colon instead of slash before user)
For expect, .equal will compare objects rather than their data, and in your case it is two different arrays. Use .eql in order to deeply compare values. Check out this link. Or you could use .deep.equal in order to simulate same as .eql. Or in your case you might want to check .members. For asserts … Read more
In short, you don’t need a dependency injection container or service locater like you would in C#/Java. Since Node.js, leverages the module pattern, it’s not necessary to perform constructor or property injection. Although you still can.
