What is the difference between the syntax of uniapp and vue

The syntax difference between UniApp and Vue

UniApp and Vue are both developed based on the Vue.js framework, so they have many similarities in syntax. However, since UniApp is a cross-platform framework that allows developers to write applications using native syntax and APIs, there are some key differences from Vue.

Template syntax

UniApp uses its own template syntax, called WXML, which is similar to the template syntax in Vue's .vue file. However, there is an additional feature in WXML called template tag, which allows developers to use native applet or app-side syntax in templates.

Script syntax

Both UniApp and Vue use JavaScript as the scripting language. However, UniApp provides specific APIs for applets and apps, which are not available in Vue. For example, UniApp has uni.request for network requests, while Vue has axios.

Style Syntax

Both UniApp and Vue support CSS as a styling language. However, UniApp also supports a style syntax called WXML, which allows developers to use native applet or app-side syntax in styles.

Component syntax

Both UniApp and Vue support component development. However, components in UniApp need to inherit the special uni- component parent class, while components in Vue do not.

Life cycle hooks

UniApp and Vue both provide life cycle hooks to respond to different state changes of components. However, there are some specific hooks in UniApp that are designed to handle mini-program or app-side functions, such as onShow and onHide.

Other differences

In addition to syntax differences, UniApp and Vue have some other key differences:

• Cross Platform: UniApp is a cross-platform framework that allows developers to use a single code base to build applications for multiple platforms (mini programs, App side, H5).
• Native integration: UniApp provides access to native applets or app-side APIs, enabling developers to create highly customized applications.
• Third Party Plugins: UniApp has its own plugin library called UniCloud, while Vue uses NPM.
