In this detailed guide, I’ll walk you through the process of setting up uni v4, covering everything from installation to configuration. Let’s get started!

Installation

Before you can begin working with uni v4, you need to install it on your system. Here’s a step-by-step guide to help you through the process:

1. Download the latest version of uni v4 from the official website.
2. Extract the downloaded file to a directory of your choice.
3. Open a terminal or command prompt and navigate to the directory where you extracted the files.
4. Run the following command to install uni v4:

Once the installation is complete, you can verify that uni v4 is installed correctly by running:

Environment Setup

After installing uni v4, you need to set up your development environment. Here’s what you need to do:

1. Node.js and npm: Ensure that you have Node.js and npm installed on your system. You can download and install them from the official Node.js website.
2. IDE or Code Editor: Choose an Integrated Development Environment (IDE) or a code editor that supports JavaScript and TypeScript. Some popular options include Visual Studio Code, WebStorm, and Atom.
3. Uni CLI: Install the uni CLI globally using npm:

npm install -g @dcloudio/uni-cli

Once the CLI is installed, you can create a new project by running:

uni init

Select the template that best suits your project needs, and follow the prompts to set up your project.

Project Configuration

After creating your project, you’ll need to configure it to work with uni v4. Here’s how to do it:

1. Open your project in your IDE or code editor.
2. Locate the config directory in your project.
3. Open the config.json file.
4. Configure the project settings according to your requirements. Here’s an example of a basic config.json file:

{  "projectname": "my-uni-project",  "appid": "your-app-id",  "description": "A simple uni v4 project",  "setting": {    "urlCheck": false,    "es6": true,    "postcss": true,    "minified": true,    "newFeature": true  },  "compileType": "miniprogram",  "libVersion": "2.8.2",  "appid": "your-app-id",  "projectPath": "path/to/your/project",  "condition": {    "miniprogram": {      "appid": "your-app-id",      "path": "/pages/index/index",      "type": "miniprogram",      "version": "release",      "platform": "android"    }  }}

Make sure to replace your-app-id with your actual app ID and path/to/your/project with the path to your project directory.

Building and Running Your Project

Now that your project is set up, you can build and run it using the uni CLI. Here’s how to do it:

1. Open a terminal or command prompt and navigate to your project directory.
2. Run the following command to build your project:

uni build

This command will compile your project and generate a minified version of your code. Once the build process is complete, you can run your project using the following command:

uni run

Select the platform you want to run your project on, and the uni CLI will launch your app in the specified environment.
