SegmentFault Sifu Technology Weekly -- Node.js advanced journey, let's see what needs to be learned?

Simply put, Node.js is JavaScript running on the server side.
Node.js is a platform built on the Chrome JavaScript runtime.
Node.js is an event-driven I/O server-side JavaScript environment. It is based on Google's V8 engine. The V8 engine executes JavaScript very fast and has very good performance.

How does Node.js implement asynchronous resource context sharing? 》

This article uses the simplest possible way to introduce how Node.js implements asynchronous resource context sharing, and how asynchronous resource context sharing is useful to us.

"Locking Project Node Version and Package Manager"

The Node.js versions of member machines are not uniform: 12.x for the old school, 14.x for the conservative, and 17.x for the radical. Whether the project can run normally depends on God's will, and the online risks can be imagined in the scenario where there is no CICD pipeline to support the local npm run build.
Some people are used to using npm, some people are used to using yarn, and there are often cases where package-lock.json and yarn.lock files exist at the same time in the code base. The more painful point is that there are no clues to troubleshoot all kinds of strange problems.
All we have to do is strangle the problem at the source: lock down the Node.js version and package manager

"Use node.js to create child processes and use WebSocket and Ipc to achieve inter-process communication"

"Node Abnormal Data Response Troubleshooting (pm2 Cluster Mode, Asynchronous)"

Do not start Cluster cluster mode:
Because the local is non-Cluster cluster mode, it behaves normally. Then the first solution is to not turn on the cluster mode in the production environment, but in general this solution is not advisable, the request in the production environment is relatively high, and the cluster mode is the optimal solution.

Increase single-instance data service | Downgrade to single-instance mode:
Similar to redis, but a new single-instance nodeJs script. Getting data & updating data is requesting this script service.
Because cluster mode is not used, there is no sharing problem. At the same time, it also avoids the problem of the previous solution, because the data service is not open to the outside world, only for the service of the intranet, so the request level will not be too large.

"[nodejs advanced journey (2)]: use koa2+mysql to implement list data paging"

The main fields of paging include pageSize number of items per page, pageNum number of pages, startRow current starting page number, endRow current ending page number, and total total number. Mainly according to the parameters of front-end paging, after processing, returning the correct data on the front-end is actually a very common and simple function, but it is also very important.

"node+express build web server deployment front-end project"

Traditional front-end project deployment relies on the tomcat service as a static resource server. With the separation of front-end and back-end processes, front-end projects need to be deployed separately. For front-end deployment, in addition to using nginx to build a static resource server, we can also use node to build a web server. Let me share with you how to use node to build a web server.
