How to write film and television applets in uniapp

With the development and popularization of mobile Internet, film and television entertainment has become an important part of people's daily lives. With the promotion of WeChat mini programs, more and more film and television mini programs have appeared in our lives. This article will explain in detail how to write film and television applets by introducing the use of uniapp.

1. Introduction to uniapp

Uniapp is a development tool based on vue.js and small program technology stack. It can convert the code of a small program into H5, iOS and AndroidNative code at the same time. Using uniapp to develop small programs eliminates the need to use different languages ​​and tools on different platforms, which can greatly reduce development difficulty and time costs.

2. Build uniapp development environment

1. Install Node.js
   First, we need to install the Node.js environment on the computer. Node.js is a JavaScript running environment based on the Chrome V8 engine, which can run JavaScript programs on your computer. We can download the installation package from the Node.js official website and install it according to the prompts.
2. Install HBuilderX
   HBuilderX is a mainstream front-end development tool. Here we use it to develop uniapp applet. We can download the installation package from the official website and start HBuilderX after the installation is complete.
3. Create uniapp project
   In HBuilderX, we click "File"->"New"->"uni-app project" in the menu bar to open the wizard for creating a uniapp project. Fill in the project name in the wizard, select a template (here we selected the default template of uni-app), specify the project path, and then confirm to create the project.
4. Run the uniapp project
   We open the created uniapp project in HBuilderX, and then click "Run" -> "Run to Mini Program Simulator" in the menu bar to run the project. Since uniapp supports multiple running modes, in addition to small programs, projects can also be run in HBuilderX through preview and packaging.

3. Basic development of the uniapp applet

After creating the uniapp project, we can start writing the applet code. In UniApp, we can use vue-style syntax for development. Next, we will introduce the development specifications and basic component usage of uniapp by writing a simple "movie list" applet.

1. Configuring the global style of the mini program

In uniapp, we need to use a global style sheet to control the style of the mini program components. You can find the "App.vue" file in the project navigation, click to open, and then add the following content at the end of the file:

<style>
    /*全局样式*/
    .page{
        display: flex;
        flex-wrap: wrap;
        padding: 10px;
        background-color: #f5f5f5;
    }
    .page-head{
        font-size: 20px;
        font-weight: 600;
        margin: 20px 0;
    }
    .movie-item{
        width: 200px;
        margin-bottom: 20px;
        background-color: #fff;
        border-radius: 5px;
        overflow: hidden;
    }
    .movie-title{
        font-size: 18px;
        font-weight: 600;
        padding: 10px;
    }
    .movie-poster{
        width: 100%;
        height: 260px;
    }
</style>

2. Create a "Movie List" page

We can use HBuilderX's file manager to create a "movie" folder in the project to store pages and components related to the movie list. Then we create a page called "movie-list" in this folder. After the creation is completed, we can enter the directory of this page and open the "movie-list.vue" file. In this file, we can write the following code:

<template>
    <div>
        <header>电影列表</header>
        <div>
            <div>
                <img  class="movie-poster lazy" src="/static/imghwm/default1.png" data-src="item.poster" alt="How to write film and television applets in uniapp" >
                <div>{{item.title}}</div>
            </div>
        </div>
    </div>
</template>

<script>
    export default {
        data(){
            return{
                // 电影列表数据
                movies:[
                    {id:1,title:"绿皮书",poster:"./static/poster/lps.jpg"},
                    {id:2,title:"波西米亚狂想曲",poster:"./static/poster/bohemian rhapsody.jpg"},
                    {id:3,title:"蜘蛛侠：平行宇宙",poster:"./static/poster/spiderverse.jpg"},
                    {id:4,title:"阿里巴巴与神灯",poster:"./static/poster/ali.jpg"},
                ]
            }
        }
    }
</script>

In this code, we display the "Movie List" page through the template syntax in uniapp. Custom components and custom styles are used in the page to display the basic information of the movie list through Vue's data binding method.

3. Create the "movie details" page
   We can also create a page named "movie-detail" in the "movie" folder to display movie details. In this page, we can also use Vue-style syntax to display information about movie details.

4. Mini Program Release and Development

After we have completed the development of the uniapp mini program, we can publish and develop it. For the release of mini programs, we can use the packaging tool provided by uniapp to generate the release package of the mini program and upload it to the WeChat mini program platform for review and release. For the development of small programs, testing and maintenance work need to be performed on different platforms.

Summary:

This article explains in detail how to develop film and television applets by introducing the use of uniapp. In actual development, we need to select appropriate components and perform necessary style and interaction customization based on actual needs. I hope that through the introduction of this article, readers can further understand the development method of uniapp applet.
