vue server shuts down

AngularJS developed by Google in the early years has become a popular choice for front-end technology experts. However, the market has gradually turned to Vue.js recently. Vue.js has gradually become one of the most popular JavaScript frameworks due to its low difficulty of getting started, small size, and strong performance. So when we use Vue.js, have we ever encountered a sudden server shutdown?

1. Cause of the problem

When we use Vue.js, we may encounter server shutdown. This is because there are some globally called operations in Vue.js, such as $mount(), $nextTick(), etc., these calls will be executed immediately when the Vue instance is created. If your server is down, these operations cannot be completed and the program will crash. Additionally, when a Vue.js instance is changed, Watchers and Computed Properties on it may also be affected.

2. Solution

In order to avoid server shutdown, we need to take the following measures:

(1) Avoid using global calls in Vue.js instances as much as possible operation. If you must use these operations, then you can use them in Vue's lifecycle function created(). At this stage, you can ensure that the Vue instance has been created, and the server can ensure that it will not shut down in the meantime.

(2) When using "Watcher" and "Computed Properties", they also need to be declared in the created() life cycle function. This way, you can ensure that these things start working as soon as the Vue instance is created, thus avoiding unnecessary crashes.

(3) In addition, you can try to use server side rendering (Server Side Rendering) to alleviate this situation. Server-side rendering can precompile Vue components on the server. In this way, even if the server is shut down, users can continue to browse the rendered content, thus avoiding program crashes.

3. Summary

In short, Vue.js is a very good front-end framework, but you should also pay attention to some factors that may affect the stability of the program when using it. Of course, what is more important is the stability and security of the cloud service provider. Therefore, when using Vue.js, we need to consider using a stable and reliable cloud server to ensure that our programs can run normally and continue to provide services.
