This article uses easy-to-understand examples to introduce how to use node.js on CVM. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Node.js is a JavaScript running environment based on Chrome V8 engine, which is used to build easily scalable network applications conveniently and quickly.

Node.js uses an event-driven, non-blocking Istroke O model, which makes it lightweight and efficient, and is very suitable for data-intensive real-time applications running on distributed devices. Node.js 's package manager, npm, is the largest open source ecosystem in the world.

Typical application scenarios of Node.js in CVM:

Real-time applications: such as online chat, real-time notification push, etc.; use stable interfaces to improve Web rendering capabilities

Distributed applications: using existing data through efficient parallel Imax O

Tool applications: a large number of tools, from front-end compressed deployment to desktop graphical interface applications

Game applications: the game field has high requirements for real-time and concurrency.

Unified front-end programming environment: front-end developers can cut into server-side development very quickly (such as the famous pure Javascript full-stack MEAN architecture)

To use node.js, the CVM needs to have PuTTY installed beforehand. The steps to install Node.js on the ECS instance and deploy the project are as follows:

1. Create and connect the ECS instance of the CVM.

two。 Choose either method to deploy the Node.js environment: install Node.js using binaries. Use NVM to install multiple versions of Node.js.

3. Deploy the test project.

So much for sharing about how to use node.js on CVM. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
