How to develop and publish mini programs in uni-app

With the development of the mobile Internet, mini programs have become an important direction in mobile application development. As a cross-platform development framework, uni-app can support the development of multiple small program platforms at the same time, such as WeChat, Alipay, Baidu, etc. The following will introduce in detail how to use uni-app to develop and publish small programs, and provide some specific code examples.

1. Preparation before developing small programs

Before you start using uni-app to develop small programs, you need to do some preparations:

1. Install development tools: Download and install HBuilderX from the uni-app official website (https://uniapp.dcloud.io/quickstart). This is a VSCode-based development tool that supports the development of uni-app.
2. Register a mini program account: If you don’t have a mini program account yet, you can go to the corresponding mini program open platform to register an account. I’ll take the WeChat mini program as an example. You can go to the WeChat public platform (https:// mp.weixin.qq.com/) to register.

2. Create the uni-app project

1. Open HBuilderX, select "File" -> "New" -> "Project" in the menu bar, and select uni -app project.
2. Enter the project name and save location, and select the corresponding template. uni-app provides many templates, and you can choose a suitable template as a basis.
3. Click the "Create" button to create a uni-app project.

3. Develop Mini Program Interface

In uni-app, you can use Vue.js to build the mini program interface. The following is a simple example:

1. Find the "pages" folder in the uni-app project, and create a new folder under this folder as your interface module. For example: create a new "home" folder.
2. Create a new vue file in the "home" folder, such as: "index.vue".
3. Edit the "index.vue" file and write the interface code. As shown below:

<template>
  <view class="container">
    <text>{{ message }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      message: 'Hello, uni-app!'
    }
  }
}
</script>

<style>
.container {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}
</style>

4. Compile and run the applet

1. In the bottom toolbar of HBuilderX, select the corresponding applet platform (such as WeChat applet).
2. Click the run button to compile the uni-app project into a small program and preview the running effect in the simulator.

5. Publish Mini Program

1. In the bottom toolbar of HBuilderX, select the corresponding mini program platform.
2. Find the "manifest.json" file in the project navigation bar and edit the applet's configuration information, such as the applet name, icon, etc.
3. Select "Publish" -> "Mini Program Publishing" in the menu bar of HBuilderX, and fill in the corresponding information according to the wizard, including the version number, description, etc. of the mini program.
4. After completing the publishing, you will get a QR code of the mini program. Scan the QR code to preview and share your mini program on your phone.

Summary

Using uni-app to develop and publish small programs is very simple, and only requires some basic settings and coding work. Through uni-app, you can develop multiple small program platforms at once, saving development and maintenance costs. I hope the above content will be helpful to you, and I wish you success on the road to mini program development!
