How do I create a new uni-app project?

To create a new uni-app project, you can follow these steps:

1. Install Node.js: Make sure you have Node.js installed on your computer. You can download it from the official Node.js website.
2. Install HBuilderX: Download and install HBuilderX, which is the recommended integrated development environment (IDE) for uni-app development. You can find HBuilderX on the DCloud official website.

3. Create a New Project in HBuilderX:

   • Open HBuilderX.
   • Click on "File" in the top menu.
   • Select "New" and then "Project".
   • In the "New Project" window, select "uni-app" as the project type.
   • Choose a template (e.g., "Hello uni-app").
   • Enter a project name and choose the location where you want to save the project.
   • Click "Create" to generate your new uni-app project.

4. Initialize the Project (Optional): If you prefer to use the command line, you can also initialize a new uni-app project using the vue-cli.

   • Open your terminal or command prompt.
   • Run the command npm install -g @vue/cli to install Vue CLI globally if you haven't already.
   • Once installed, run vue create -p dcloudio/uni-preset-vue my-uni-app to create a new uni-app project named my-uni-app.
5. Start Development: After creating the project, you can start development by running the project in HBuilderX or using the command line. In HBuilderX, right-click on your project folder, select "Run" -> "Run to Browser" to see your app in action.

What are the system requirements for developing a uni-app?

The system requirements for developing a uni-app are relatively straightforward and include:

1. Operating System: Windows 7 or above, macOS 10.10 or above, or Linux.
2. Node.js: Version 8.9 or above. Node.js is essential for using npm to manage dependencies and for running the uni-app development server.
3. HBuilderX: The recommended IDE for uni-app development. You can download the standard edition for free, or you can opt for the professional edition for additional features.

4. Hardware:

   • A computer with at least 4GB of RAM (8GB or more recommended for smoother performance).
   • Sufficient storage space to accommodate the project files and any required development tools.
5. Internet Connection: A stable internet connection is needed for downloading dependencies and for accessing online resources or documentation.

These requirements ensure that you can develop and test uni-app projects efficiently across different platforms.

Can I use existing frameworks like Vue.js with uni-app?

Yes, you can use existing frameworks like Vue.js with uni-app. uni-app is built on top of Vue.js, making it fully compatible with Vue 2.x syntax. Here's how you can leverage Vue.js within uni-app:

1. Vue Syntax: uni-app supports Vue's Single File Component (SFC) format, which means you can write your components in .vue files using Vue's template, script, and style sections.
2. Vue Lifecycle Hooks: You can use Vue lifecycle hooks like created, mounted, updated, etc., within your uni-app components.
3. Vuex: uni-app fully supports Vuex for state management. You can set up a Vuex store in your uni-app project just as you would in a regular Vue.js application.
4. Vue Router: While uni-app uses its own navigation system, you can still leverage some features of Vue Router. For complex navigation scenarios, uni-app provides uni.navigateTo, uni.redirectTo, and other APIs.
5. Plugins and Libraries: Many Vue.js plugins and libraries can be used in uni-app with minimal adjustments. You can install these via npm and import them into your uni-app project.

By using Vue.js within uni-app, you can take advantage of Vue's robust ecosystem and familiar development patterns while still benefiting from uni-app's multi-platform capabilities.

Which templates or presets should I choose when starting a new uni-app project?

When starting a new uni-app project, you have several templates or presets to choose from, each suited to different use cases:

1. Hello uni-app: This is the default template and is recommended for beginners. It includes basic examples of various uni-app features and is a good starting point for understanding the framework.
2. uni-ui Project: This template comes with uni-ui, a UI library specifically designed for uni-app. It's ideal if you want to quickly prototype and build apps with a consistent and responsive UI.
3. Tabbar Project: If your app requires a tab bar at the bottom, this template is suitable. It includes a pre-configured tab bar that you can customize according to your needs.
4. Custom Template: You can also start from a blank template if you want complete control over your project structure and want to set everything up yourself.
5. Vue3 Project: If you prefer to work with the latest Vue.js version (Vue 3), you can choose the Vue3 template. This is useful if you want to use Vue 3 features within your uni-app project.

Choosing the right template depends on your specific project requirements, your familiarity with uni-app, and whether you need specific UI elements or navigation structures from the start. If you're new to uni-app, the "Hello uni-app" template is a safe and educational choice.
