How to develop small programs with Uniapp

With the popularity of mobile devices, mobile applications (Apps) are becoming more and more widely used. As a lightweight application, mini programs are increasingly popular among users. Developing small programs has also become a hot topic among programmers. Using Uniapp to develop small programs can not only improve development efficiency, but also allow programmers to more easily develop cross-platform small programs. Next we will introduce how to develop small programs with Uniapp.

1. Introduction to Uniapp

Uniapp is a multi-terminal development framework based on Vue.js. It has the advantages of efficient development, ultimate performance and native experience. It can simultaneously develop WeChat applets, H5, Multi-terminal applications such as App integrate the advantages of various development platforms and are very simple and convenient to use.

2. Create a project

First, you need to go to the HBuilder X official website to download and install it. Then create a new project, select "Uniapp Project", and then select the platform that needs to be developed (such as WeChat applet, H5, etc.).

3. Use of components

1. Page composition

Each mini program page is composed of three components, namely view, data ) and logic (method). We need to write code in the page.vue file to complete a mini program page.

2. Use of components

Uniapp has multiple built-in components, which can prevent developers from manually writing complex HTML and CSS codes, making development more efficient. For example, icons, buttons, forms, etc. can be introduced where needed and the corresponding attributes can be set.

4. API calls

1. Third-party API

Mini programs developed using Uniapp can access third-party APIs, such as weather API, map API, etc. The network request whitelist needs to be configured in the manifest.json file to allow the applet to access related APIs.

2. System API

Uniapp provides a variety of system APIs, such as making calls, sending text messages, scanning QR codes, etc. Developers can directly call these APIs in components such as uni.request to meet corresponding needs.

5. Debugging and Release

1. Debugging

Uniapp provides a very convenient debugging tool during the development process, which can be previewed and debugged in real time in HBuilder X. It is convenient for developers to debug programs.

2. Release

Uniapp can be released to multiple terminals at one time. Developers only need to compile once and select different platforms when publishing to publish the mini program to the corresponding platform. .

To sum up, Uniapp development of small programs can improve development efficiency and facilitate the writing of cross-platform small programs. By being familiar with the basic usage and API calls of Uniapp, it can help developers develop small programs more easily.
