So, instead of a single instance of Node.js running on a single thread, we can launch a cluster of Node.js processes to handle the load. Clusters allow us to take advantage of multi-core systems. We could further scale with the addition of load-balancers or via clusters. When the food is ready they will be called upon again to deliver the food from the kitchen to the respective table. They are then free to take another order and bring it to the kitchen. To better explain this I liken it to a restaurant with one waiter and five tables.Ī blocking system - The waiter takes down an order for a table and is unable to serve any other tables until the food has been prepared and delivered from the kitchen.Ī non-blocking system - The waiter takes an order and brings it to the kitchen. JavaScript by design is a single-threaded language which means it can only process one command at a time, so its methods are considered blocking methods but it has asynchronous capabilities which allow its methods to be non-blocking.
Ideal applications for Node.js could include chat applications, a stockbrokers dashboard, monitoring dashboard, or a reverse proxy that is used during development instead of nGinx Scaling considerations There's a great ecosystem and its architecture suits lightweight, high traffic, data-intensive (but low processing/computation) applications that run across distributed devices.
Node will give us the ability to use JS on both the frontend and the backend, allowing for full-stack JavaScript development and has an easier learning curve for existing JS developers.
It is primarily used for non-blocking, event-driven servers.
js is a running environment for JavaScript. In this deep dive, we will step through these considerations looking at expected behaviors, technology decisions, support packages, and security requirements.īefore we do that, let’s do a sneak peek at the stack we’ve selected and what they have to offer. Building an application API that can manage user registration and authentication inspires consideration.
