With the popularity of mobile Internet, people's demand for mobile applications is gradually growing. In order to meet different business needs, the development of mobile applications has become more and more complex. In this case, uniapp, as a cross-platform development framework, has become the first choice for developers.
Uniapp is a cross-platform application development framework that runs based on the Vue.js framework and Web Components specifications. It can develop mobile applications that support H5, mini programs, App and other platforms. Because the development model of uniapp has the characteristics of unified code writing and cross-platform, it is paid attention to and used by more and more developers.
During the development process using uniapp, developers can choose to enable different modules to better complete project development. So in actual applications, how to enable different modules? This article will give detailed tutorials.
During the development process using uniapp, uniapp will enable some basic modules by default, such as: 'uni-app': '1.0 .0'
. There are 3 module types in uniapp, which are:
Each module type has its unique role in uniapp and can meet different application needs.
In actual applications, developers can enable different modules by modifying the manifest.json file. The manifest.json file is the configuration file of the uniapp project, in which you can define the startup method, page path and other related information of uniapp.
In the manifest.json file, the modules field is used to enable different modules. For example:
{ "name": "uni-app", "description": "", "appid": "", "version": "1.0.0", "modules": { "System": "1.0.0", "WebView": { "version": "1.0.0" } } }
In the above code, "System" and "WebView" are both custom modules, and developers can choose whether to enable them in the project. If you do not need to use a custom module, you can delete it directly in the manifest.json file.
In order to better demonstrate how to enable different modules, let’s take a custom module as an example and give specific steps:
First, create a new uniapp project in VSCode. The specific steps will not be introduced in detail. What should be noted here is that during the process of creating the project, you need to select the "Custom Component" option to facilitate subsequent custom module operations.
In the new project, right-click and select "New File", then select "Custom Component" to create a new custom component. Here we create a component named "my-component" and add a text box in it. The code is as follows:
<template> <div class="container"> <input type="text" placeholder="请输入内容" v-model="text"> </div> </template> <script> export default { data() { return { text: '' } } } </script>
After the custom component is written, you need to click "Auto" in "Compile Mode" on the menu bar. Define component patterns" so that custom components can be successfully introduced later.
In the root directory of the project, find the manifest.json file, find the modules field, add a new custom module, code As follows:
{ "name": "uni-app", "description": "", "applet": "0.1.0", "modules": { "System": "1.0.0", "my-component": { "version": "1.0.0", "provider": "default" } }, "condition": { "network": { "wifi": true } } }
In the above code, "my-component" is the name of the custom component we wrote in the code, "version" represents the version number of the custom component, and "provider" represents the provider of the component .
In the App.vue file, find the script tag and import the custom component in it. The code is as follows:
import myComponent from '@/components/my-component.vue' export default { components: { myComponent } }
In the above code, @ represents the address of the src directory, and "my-component.vue" is the file name of the custom component.
After completing the above steps, you can use the custom components in the page. Add the following code to the template tag of the page:
<template> <div class="container"> <my-component></my-component> </div> </template>
In the above code, "my-component" is the name of the custom component we wrote in the code.
uniapp is a very powerful and flexible cross-platform application development framework. By enabling different modules, developers can better complete project development and apply it in practice. play greater value. This article introduces how to enable different modules in uniapp, and takes a custom module as an example to give detailed steps. I believe it can be helpful to developers.
