Why is nodejs update so slow?

Node.js is a very popular JavaScript runtime environment that not only allows front-end developers to leverage their expertise in back-end development, but also helps developers build high-performance network applications. However, many developers have encountered many problems in the process of updating Node.js, the most common of which is that the upgrade is very slow. So why are Node.js updates so slow?

First of all, what you need to understand is that the update of Node.js not only involves the update of Node.js itself, but also includes the corresponding npm package. Due to the large number of npm packages, the update time will be affected. In addition, Node.js needs to download and compile the source code when updating. This process is very time-consuming, especially on low-configuration machines, and the update time will be longer.

Secondly, due to the relatively high frequency of Node.js updates, and the Node.js development team has been constantly optimizing its performance and stability, the new version of Node.js usually contains a large number of Updates and improvements. These updates and improvements involve many different aspects, such as network performance, memory management, security, etc. These updates and improvements require testing and verification, thus requiring more time, resources, and manpower.

In addition, since Node.js is an open source project, contributors in this community need to be valued. Some updated parts may be completed outside of the project's developers, so the pace of updates may be affected by the time investment of external contributors.

However, these problems are not unsolvable. Here are some practical tips to speed up your Node.js upgrade:

1. Use an updated version controller. NVM or N Version Manager has many useful features, including installing multiple different Node.js versions on your machine simultaneously and easily switching between them.

2. Use binary files. Node.js provides binary downloads for Windows, MacOS, Linux, and more. Typically, they are much faster than compiling from source.

3. Delete the old version of npm package. When updating Node.js, you can consider deleting the old version of the npm package at the same time, which will help reduce the update time.

4. Use an appropriate mirror source. If you are located in China, you can use Taobao mirror source or domestic high-speed mirror source when updating Node.js, which can download and install Node.js faster.

Node.js updates can help developers obtain better network application performance and a better development experience. Although updates may be slow, some optimization techniques can help us shorten the update time and get the benefits of the update faster.
