Front-end Vue component development: design and implementation of custom tabbar components compatible with Apple Liu Haiping applets and APPs
Abstract:
With the continuous development of front-end development technology, component development has become an effective means to improve development efficiency and reduce maintenance costs. This article will introduce the design and implementation of a front-end custom tabbar component based on Vue. This component has the advantages of independent development, independent maintenance, and flexible combination. Efficient development in complex business scenarios can be achieved by combining module splitting strategies with business characteristics, interaction methods between modules, and building systems. This article will also elaborate on the implementation process of the tabbar component, including discussions on design ideas, key technologies, performance optimization, and application scenarios.
I. Introduction
In front-end development, interface design is crucial. A beautiful, easy-to-use, and stable bottom tabbar can greatly improve the user experience. However, traditional development methods often develop the bottom tabbar and the entire application as a whole, which makes it difficult to modify and extend the bottom tabbar. Once changes are needed, the entire application may need to be redesigned and implemented, which greatly increases the development time. costs and maintenance costs.
In order to solve this problem, this article proposes the design and implementation of a front-end custom tabbar component based on Vue. Through component development, the bottom tabbar can be disassembled from the entire application and developed and maintained separately, thereby improving development efficiency and quality. At the same time, this component also has flexible combination and expansion capabilities to meet various business needs.
2. Technical background and market demand
With the development of Internet technology, the scale and complexity of Web applications continue to increase, and the demand for efficient and maintainable front-end development is also increasing. As a popular front-end framework, Vue.js's component-based development model has been widely used. Through component development, complex web applications can be split into a series of reusable components, so that each component can be developed, tested and maintained independently, greatly improving development efficiency and quality.
In terms of market demand, as users have higher and higher requirements for interface design, the demand for efficient, beautiful, and easy-to-use bottom tabbars is also getting higher and higher. Therefore, developing a bottom tabbar component with good performance and easy expansion has broad market prospects and application value.

3. Technical implementation
- Design ideas
The design idea of the custom tabbar component is to create a reusable component that can receive a parameter (the index of the tabbar that needs to be displayed) and display the corresponding tab based on this parameter. At the same time, this component also has the function of hiding the native tabbar, which is achieved by calling the uni.hideTabBar() function.
- Key technologies
The key technologies for implementing the tabbar component include the following:
(1) Use the component development model of the Vue framework to split the tabbar component into multiple small independent modules so that each module can be developed and maintained independently.
(2) Based on the module splitting strategy based on business characteristics, the tabbar component is split into multiple small modules, such as tabbar style, tabbar icon, etc., so that each module can be flexibly combined and expanded.
(3) Use CSS to customize and optimize styles to achieve a beautiful and easy-to-use interface effect.
(4) Combined with the build system, package the tabbar component into an independent JavaScript file for easy use in projects.
- Code
The following is the Vue code implementation of the custom tabbar component:
#### Instructions
```How to use
<!-- tabBarShow: Which tabbar to display -->
<cc-myTabbar :tabBarShow="0"></cc-myTabbar>
<!-- Hide native tabbar -->
onReady() {
uni.hideTabBar()
}
<!-- 140rpx from the bottom of the page (custom tabbar height) -->
page {
padding-bottom: 140rpx;
}
```
#### HTML code implementation part
```html
<template>
<view class="page">
<!-- tabBarShow: Which tabbar to display -->
<cc-myTabbar :tabBarShow="0"></cc-myTabbar>
</view>
</template>
<script>
export default {
data() {
return {
};
},
onReady() {
uni.hideTabBar()
},
methods: {
}
}
</script>
<style scoped lang="scss">
page {
padding-bottom: 140rpx;
}
</style>
```
