Why can't vue complete automatically?

With the rapid development of front-end frameworks, Vue.js has become more and more widely used in recent years. However, during the actual writing process of Vue.js, some developers will find that the IDE does not implement the automatic completion function when writing Vue.js code, which may cause inconvenience to some developers.

So, why can’t Vue.js automatically complete it? The reason is as described below:

Vue.js is a framework written in JavaScript, and its component pattern makes modular development very prominent. In fact, this also brings challenges to the implementation of the automatic completion function of Vue.js components in the IDE.

In order to achieve automatic completion, the IDE needs to understand the model, data and methods of the component template, and have a relatively strong intelligent syntax parsing system. However, in Vue.js, the data of the component is dynamically bound, that is to say, the type and properties of the data cannot be clearly known before the component is instantiated. Therefore, although development tools such as IDEA can statically parse the component content of Vue.js, they do not have the ability to dynamically track data types and properties. In other words, IDE cannot understand the relationship between syntax and dependent components in advance. It cannot provide real-time completion for developers.

So, how do we solve the problem that Vue.js cannot automatically complete it? The following are some countermeasures:

1. Scientific selection of IDE

For the development of the Vue.js framework, we can choose some IDEs that support Vue.js, such as Visual Studio Code , WebStorm, Sublime Text, etc. Among them, WebStorm is a very professional front-end development tool and has very good support for Vue.js. After installing WebStorm, we need to configure the Vue.js version in the Project Setting. In addition, we can also install the Vue.js plug-in in WebStorm's Marketplace, which can effectively improve the efficiency of code writing.

2. Introduce the jsconfig.json file

Since automatic completion requires understanding the component model, data and methods of Vue.js, etc., you can try to introduce the jsconfig.json file. accomplish.

In WebStorm, we can create a jsconfig.json file in the project and add the Vue.js library to the file. This operation mainly involves embedding Vue.js into the project as an external library. After that, we can use the automatic completion mechanism provided by the IDE to make coding faster, but real-time completion may still be subject to some limitations.

3. Open the Vetur plug-in

The Vetur plug-in is one of the advanced IDE plug-ins for developers for Vue.js. It provides syntax highlighting, Error checking, auto-completion, code snippets and more. After installing this plug-in, we can turn on the automatic completion function, making code writing more convenient.

In summary, although Vue.js cannot support automatic completion like other front-end frameworks, there are some methods and techniques that can help developers improve the efficiency and accuracy of code writing. We can make the process of writing Vue.js code smoother and easier by selecting and setting up a suitable IDE, introducing the jsconfig.json file or opening the Vetur plug-in.
