Foreword

This article mainly introduces the overview and environment construction of the project:
This project is a community developed based on uni-app Dating APP; the environment construction is mainly based on HbuilderX, and you can test and run the project after you create it; at the same time, in order to be compatible with multiple platforms, it is necessary to build a multi-terminal debugging environment, including Android, iOS, WeChat applet, Alipay applet, etc.

1. Project Introduction

This project is based on uni-app, which is a practical development of community dating apps, achieving one-time development, Multi-terminal publishing, simultaneously published to Android app, iOS app, WeChat applet, Alipay applet and other platforms, in which the back-end interface is implemented using Python Django.
The project includes post module, topic module, search module, membership module, chat module, advertising module and other modules, etc., and finally achieves rich functions and beautiful interface. Part of the interface is as follows:

The dynamic demonstration effect is as follows:

2. Environment setup and project creation

1. Development environment setup

The core editor of this project The tool is HBuilderX, which can be downloaded from the official website https://www.dcloud.io/hbuilderx.html. Just select the required system and version to download.
After downloading, unzip it to the installation directory, and click HBuilderX.exe in the unzipped directory to use it.

After opening, the interface is as follows:

In order to speed up development, you can install some plug-ins. Click on the navigation bar → Tool plug-ins → Install to select Required plug-in installation, HBuilderX has installed some core plug-ins by default, such as App real machine running, uni-app App debugging, etc. Such plug-ins do not support installation from the plug-in market.
You can also choose to install scss/sass compilation, etc. You can select it in the DCloud plug-in market https://ext.dcloud.net.cn/?cat1=1&cat2=11&orderBy=TotalDownload and install it by using HBuilderX to import the plug-in.

2. Create a uni-app project

Use HBuilderX to create an initial project, select uni-app, named Community_Dating, as follows:

After creation, it can be debugged and run, and can be run to multiple terminals such as APPs and small programs.
Take Android APP debugging as an example. If you choose real machine test, you need to connect the phone in advance and turn on USB debugging. The process is as follows:

Obviously, it has been successful. Run the APP on the Android side.

3. Multi-terminal debugging environment construction

1. Android phone debugging configuration

Real machine debugging will be displayed to the maximum extent The status of the APP in actual operation.
Taking Huawei Nova2 as an example, after connecting the USB data cable to the mobile phone, you need to change the connection method to transfer files, as follows:

Then open the developer mode. If it is the To open it once, you need to click the version number multiple times, and then open USB debugging. The process is as follows:

At this time, the real device just added will be added to the running options, as follows:

You can click to debug at this point. The process is the same as running the APP in "2. Environment setup and project creation".
At the same time, it supports real-time updates to APP and dynamic debugging when changing the project code, as follows:

As you can see, dynamic compilation and update are implemented.

2. iOS real machine debugging configuration

Use the data cable to connect to the iPhone and install iTunes for screen projection.
When debugging, the following prompt may appear:

That is, Untrusted enterprise-level developer needs to be set up, enter settings → General → Device Management → Digital Heaven (Beijing) lnternet... → Trust "Digital Heaven (Beijing) Internet & Te..., then enter the application for debugging, and you can run the APP successfully.

3. WeChat applet debugging configuration

When using WeChat applet for debugging, you need to install the WeChat developer tools first. You can directly click https://mp.weixin.qq .com/debug/wxadoc/dev/devtools/download.html Select the appropriate system and version for installation.
Before debugging, two steps of configuration are required, as follows:
(1) Configure WeChat development The installation path of the developer tool;
(2) WeChat developer tool opens the service port.

For details, please refer to the second part of https://blog.csdn.net/CUFEECR/article/details/111088889.

The running process is as follows:

You can also preview and debug on the real machine.

4. Alipay applet debugging configuration

Before using the Alipay mini program to debug, you need to install the mini program developer tool. You can click https://opendocs.alipay.com/mini/ide/download to select the appropriate version and system and install it.
After installation, you need to set the Alipay Mini Program Developer Tool path, as follows:

At this time, run to the Alipay Mini Program Developer Tool, as follows:

You can see that the Alipay applet is running and dynamic compilation is implemented.

In addition to previewing in the developer tools, you can also preview on a real machine, as follows:

Achieved the same preview effect.

Summary

As a front-end framework for developing cross-platform applications using Vue.js, uni-app can Achieve writing a set of Vue.js code, which can be compiled to multiple platforms such as iOS, Android, WeChat applets, etc., achieving multi-terminal sharing, greatly reducing development and learning costs, and accelerating development. Use uni-app to develop community dating classes APP can also quickly achieve the effect of publishing a set of codes to multiple platforms.
