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:
