Should I use cdn or npm to separate the front-end and back-end of the vue project?

In recent years, the development model of front-end and back-end separation has become more and more popular and concerned by developers. With the continuous emergence of Vue projects, the front-end and back-end separation model is becoming more and more commonly used. For Vue projects, how to choose CDN or NPM? Different projects will have different choices. Here I will use my experience to discuss how to choose CDN or NPM mode in a Vue project.

1. CDN Mode

The main advantage of choosing CDN mode is performance and stability. Vue provides a CDN out of the box, which often saves server resources and improves the loading speed of Vue projects. Moreover, using CDN can effectively cache public Vue libraries, which can greatly reduce the load on the server.

The shortcomings of the CDN model are also obvious, that is, the Vue library version we use is maintained by the CDN, the update frequency is low, and the latest version may not be released in a timely manner. Furthermore, we cannot customize requirements or solve problems ourselves.

2. NPM mode

Compared with CDN, NPM has a higher degree of freedom in installing the Vue library, and you can freely choose the required version. Using NPM requires building, which is more convenient for the management of the entire project. Manually installing dependency packages through NPM can accurately plan the construction of the entire project, which is also beneficial to the development efficiency of the project. This model is also conducive to code maintenance and collaborative development. Moreover, NPM mode is often updated with the latest version in a timely manner, which will make the project more maintainable.

The disadvantage of NPM mode is that it increases the burden on the server side, which makes the construction and deployment of NPM mode more time-consuming. For big projects, this can be a very big problem. In addition, temporary NPM dependency package download problems may occur on different machines, which may disrupt the project's deployment process.

3. Summary

In the front-end and back-end separation mode of the Vue project, CDN and NPM each have their own advantages and disadvantages. If your project needs to be fast, stable and simple, then using a CDN is a good choice. For large-scale projects with long development cycles, or when there are higher customization requirements for project needs, NPM may be a better choice. Therefore, in the Vue project, whether to choose CDN or NPM depends on the specific situation. You can choose the appropriate solution according to the project needs.
