npm init -y npm i --save express express-validator mustache-express

The basics. With our packages ready, let's go on and create our index.js. We will...

In this example we'll see how to create an HTTP API with 3 main components: Signup, Login and a login-only route. Let's start by setting up a new project and including Express for handling the routes, JSON Web Token to handle auto-expiring tokens, and bcrypt to encrypt user passwords.

npm init -y npm i --save express jsonwebtoken bcrypt

Introduction In this example we'll see how to utilize Nightmare, Xvfb and how to properly bootstrap the main application code in order to make a cross-platform HTML → PDF script.
Let's start by initializing our application packages and preparing the application index.js. While we are in our new application folder, let's create a default package.json and install the packages:

npm init -y npm i --save nightmare @cypress/xvfb...
