Learn Docker - DevOps with Node.js & Express


Curriculum for the course Learn Docker - DevOps with Node.js & Express

Learn the core fundamentals of Docker by building a Node/Express app with a Mongo & Redis database. We'll start off by keeping things simple with a single container, and gradually add more complexity to our app by integrating a Mongo container, and then finally adding in a redis database for authentication. We'll learn how to do things manually with the cli, then move on to docker compose. We'll focus on the challenges of moving from a development environment to a production environment. We'll deploy and Ubuntu VM as our production server, and utilize a container orchestrator like docker swarm to handle rolling updates. ✏️ Course developed by Sanjeev Thiyagarajan.

How To Append Data to HTML5 localStorage or sessionStorage?

The localStorage property allows you to access a local Storage object. localStorage is similar to sessionStorage. The only difference is that, while data stored in localStorage has no expiration time untill unless user deletes his cache, data stored in sessionStorage gets cleared when the originating window or tab get closed. These are new HTML5 objects and provide these methods to deal with it: The following snippet accesses the current domain's local Storage object and adds a data item to it using Storage.setItem() . localStorage.setItem('myFav', 'Taylor Swift'); or you can use the keyname directly as : localStorage.myFav = 'Taylor Swift'; To grab the value set in localStorage or sessionStorage, we can use localStorage.getItem("myFav"); or localStorage.myFav There's no append function for localStorage or sessionStorage objects. It's not hard to write one though.The simplest solution goes here: But we can kee
