vue 响应式ui

Are you thinking of building something awesome with one of the popular modern frameworks out there right now, but don’t know how to get started?

您是否正在考虑使用当前流行的现代框架之一来构建出色的东西，但不知道如何入门？

If yes, then this post will help you get a kick started and build something awesome.

如果是的话，那么这篇文章将帮助您入门并建立一些很棒的东西。

What are we going to build?
我们要建造什么？

We will be building a responsive client side search of the 7 wonders of the world with the following features:

我们将通过以下功能对世界7大奇观进行响应式客户端搜索：

Text Search & Filters based on Ratings and Likes.
基于评级和喜欢的文本搜索和过滤器 。
2 items per row for Tablet and Desktop, 1 item per row for Mobile.
平板电脑和台式机每行2项， 移动设备每行1项。
Fetching data asynchronously from external API on client side.
从客户端的外部API异步获取数据。
Responsive view as shown below:

科技架构 (Tech Architecture)

We will be working with the following technologies:

我们将使用以下技术：

Vue.js: The Progressive JavaScript Framework
Vue.js ：渐进式JavaScript框架
BootstrapVue: It provides one of the most comprehensive implementations of Bootstrap V4 components and grid system available for Vue.js 2.5+, complete with extensive and automated WAI-ARIA accessibility markup.
BootstrapVue ：它提供了适用于Vue.js 2.5+的Bootstrap V4组件和网格系统的最全面的实现之一，并带有大量且自动的WAI-ARIA可访问性标记。
Vue Cli 3: Standard Tooling for Vue.js Development
Vue Cli 3 ：用于Vue.js开发的标准工具

项目结构 (Project Structure)

To get started with our Vue project, we need to setup many things like Vue, Bootstrap, Vue Router, Vuex, etc.

要开始我们的Vue项目，我们需要设置许多东西，例如Vue，Bootstrap，Vue Router，Vuex等。

Vue Cli provides us the command to create the project with most of the needed configurations.

Vue Cli向我们提供了使用大多数所需配置来创建项目的命令。

npm install -g @vue/cli
vue create project-name

For the remaining things like BootstrapVue, vue-star-rating, etc, we can use the npm install command.

对于BootstrapVue，vue-star-rating等其余内容，我们可以使用npm install命令。

The default project created using vuecli has the following structure:

使用vuecli创建的默认项目具有以下结构：

/Root Folder Public/src/assets/  /* Static assets like images goes here */components/ /* Small part of a view */views/  /* View represents a page composed of several components*/App.vue /* The main view inside which the routing logic goes */main.js  /* App initialisation happens here  */router.js /* Router logic is defined here */store.js /* Optional state management library Vuex */package.json /* It consist of all the dependencies of the project. */......

The above things are there to explain the project architecture to you and the way to initialise it.

以上是向您解释项目架构以及初始化方式的内容。

We can get started by cloning the repository and writing the following commands:

我们可以通过克隆存储库并编写以下命令来开始使用：

npm install 
npm run serve

Some important components explained:

一些重要的组件进行了解释：

components/Header.vue

组件/Header.vue

The header has been created in the form of a single independent component so that it can be reused across pages, avoiding duplication of the code.

标头以单个独立组件的形式创建，因此可以在页面之间重用，从而避免了代码重复。

/* Vue style of writing component: template, script and style*/
<template><div class="pad-15-hor pad-15-ver header"><div><img src="@/assets/logo.png" width="25px"> Responsive Search</div><div><i class="fas fa-bars"></i></div></div>
</template>
<script>
export default {name: "Header"
};
</script>
<style scoped>
.header {display: flex;flex-flow: row wrap;justify-content: space-between;
}
</style>

components/Main.vue

组件/Main.vue

This component consist of the entire logic of search / filters and display of results fetched from the API.

此组件包含搜索/过滤器的整个逻辑以及从API提取的结果的显示。

This component is using the above Header by importing it in the script.

该组件通过将其导入脚本中来使用上述标题。

<template><div><Header/><div class="pad-15-hor pad-15-ver search-parent"><div class="search-bar"><b-form-input@input="search_text()"v-model="search.text"type="text"placeholder="Search by Name"></b-form-input><span class="search-icon"><i class="fas fa-search"></i></span></div><div><span class="bold">Total Likes:</span>{{likes.count}}<span class="bold">Hits:</span>{{likes.hit}}</div><div><b-form-select @input="sort()" v-model="search.filter" :options="options"/></div></div>
