Webpack is a popular module bundler, a tool for bundling application source code in convenient chunks and for loading that code from a server into a browser. It's an excellent alternative to the SystemJS approach used elsewhere in the documentation. Cheat-sheets / JS-RxJS.md Go to file Go to file T; Go to line L; Copy path Copy permalink.

Cookie management is not the most difficult thing to do in Express.js, but there are a lot of solutions out there to help you which can make things quite confusing. We’re going to look at a very raw implementation of cookies. If you want to learn more about what browser cookies are, I recommend reading this article first.
What We’re Building
We’re going to make a little grocery store application using Express.js and as little other libraries as possible. You can see my extremely boring implementation of it at temporas.laeeto.com To get started we will run:
Our application will have an app.js file and a productDao.js file.

Module: app.js
Module: apiRouter.js
Sending Cookies in Express.js
Before looking at any other library, we can see that Express has a cookie property on the Response object.
Module: sessionHandler.js

Getting Cookies in Express
A great utility is cookie-parser. You can use it to attach a new interface to your Express Request and Response instances. It is an extremely simple library and I highly recommend you check out the source code.
For learning purposes, we’ll use as few libraries as we can. But in your project you should use libraries like express-cookie to read the request’s cookies, express-session to manage sessions and || orcookie-parser to parse cookies.
Module: sessionHandler.js
Now that we know how to create and read session cookies, let’s create some sessions.
Unique Session IDs
In my opinion, the best tool in Node.js to get unique identifiers is the uuid package. We’ll assign one unique identifier to each client.
Module: sessionHandler.js
Writing Our Shopping Routes
Here’s the route definitions for our cart:
Module: apiRouter.js
You might have noticed that the application’s management is stateful. This means that if the server reloads we loose all of our sessions. That’s why we’ll want to use JWT tokens or Redis to make it stateless.
