How does uniapp develop small programs and APPs?

With the continuous development of mobile Internet, more and more people are paying attention to the development of mobile applications. Developing a good application requires an excellent development tool, among which unipapp is a good choice.

uniapp is a cross-platform development framework based on the Vue.js framework. It can simultaneously develop WeChat applets, Alipay applets, Baidu applets, H5, App and other platforms. The following is the specific method for uniapp to develop small programs and APPs.

Step one: Install uni-app

First you need to install uni-app. You can use the npm tool to enter the following command on the command line:

npm install -g @ vue/cli @vue/cli-service-global
vue create -p dcloudio/uni-preset-vue my-project

After the command line is installed, you can proceed to the next step.

Step 2: Create pages and components

In uniapp, the creation method of pages and components is similar to Vue.js. You can use the component's life cycle and hook functions to initialize data, bind events, and other operations.

You can create a component with the following code:

<template>
  <view>
    <text>{{ message }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello World'
    }
  }
}
</script>

This code creates a variable named message and initializes it to Hello World. This variable can be bound to the template.

Step 3: Introduce plug-ins and libraries

In uniapp, we can easily introduce third-party plug-ins and libraries to enhance the functionality of the application. For example, you can use Vuex to manage state and use axios to initiate network requests.

You can use the following code to install these two libraries:

npm install vuex
npm install axios

Introduce the plug-in in main.js:

import Vue from 'vue'
import Vuex from 'vuex'
import axios from 'axios'
Vue.use(Vuex)
Vue.prototype.$http = axios

Step 4: Package and publish the application

The last step is to package and publish the application. We can use the packaging tool provided by uniapp to package the application into different release packages such as apk, ipa, and applet. After packaging is completed, it can be uploaded to various app stores for publication.

The above are the basic methods for developing uniapp applets and APPs. If you want to learn more about uniapp, you can refer to the official uniapp documentation.
