How to switch projects in uniapp

UniApp is a mobile development platform based on the Vue.js framework, which allows developers to use the same set of code to develop applications that support multiple mobile platforms at the same time. When developing UniApp projects, sometimes we need to switch between different projects. Here is a detailed introduction to how to switch projects in UniApp.

1. Switch projects through the command line

Enter the project root directory in the command line terminal and find the manifest.json file. In this file, you can see the basic information of the current project.

To switch to another project, just replace the project's manifest.json file with the file of the current project. When using the command npm run dev:%PLATFORM% to start the development service, Uni-CLI will automatically identify the manifest.json file in the project root directory and use it to generate the application.

It should be noted that before switching projects, back up the original manifest.json file to avoid data loss.

2. Switch projects through Uni-CLI commands

Uni-CLI is a command line tool that can help developers create, package, compile and debug UniApp projects. In addition to starting the development service with the npm run dev command, we can also use the dev command provided by Uni-CLI to start the development service.

Uni-CLI's dev command provides the --pkg parameter to specify which project to start.

For example, we need to switch to another project and perform the following operations:

uni-cli-service dev --pkg path/to/manifest.json

Among them, the --pkg parameter specifies the path where the project is located. After executing the above command, Uni-CLI will automatically identify the project path and use it to start the development service.

3. Switch projects through HBuilderX IDE

HBuilderX IDE is a powerful integrated development environment that can support the development of mainstream frameworks such as Vue.js and React. It also supports the development of UniApp projects and supports switching between different projects.

After opening HBuilderX IDE, you can find the project tree structure in the left navigation bar. In this tree structure, you can see the workspace of the current project. To switch to another project, just double-click to open the project's workspace and switch to the project.

It should be noted that before using HBuilderX IDE to switch projects, you need to ensure that the project workspace has been set up correctly.

The above are three methods on how to switch projects in UniApp. Whether through the command line, Uni-CLI command or HBuilderX IDE, you can easily switch and manage different projects, which brings great convenience to developers. Hope this article is helpful to everyone!
