Using Vue.js for front-end development in Beego

WBOYOriginal: 2023-06-22 14:45:111510browse

As web applications become more and more complex, the importance of front-end technology becomes more and more obvious. As a developer, we need to choose a suitable front-end development framework to help us achieve faster and more efficient development. Currently, Vue.js is a very popular front-end framework, which has the advantages of flexibility, ease of use, and high performance. On the back end, Beego is a fast, flexible, and scalable Go language web framework.

In this article, we will introduce how to use Vue.js for front-end development in Beego.

Preparation

Before you start using Vue.js, make sure that Node.js and NPM (Node.js package manager) have been installed. You can download and install Node.js from the official website [https://nodejs.org/en/](https://nodejs.org/en/).

Next, we need to introduce Vue.js resources into the Beego project. There are two ways to achieve this:

Introduce CDN resources of Vue.js into the page
Introduce Vue.js resources through NPM

Here we Choose the second way. Using NPM to manage front-end resources allows for better dependency management and simplifies our development.

Enter your Beego project directory in the terminal and execute the following command:

npm install vue --save

This will add a node_modules directory and a to your project package.json file, Vue.js will be saved in node_modules. Vue.js can be used in any file in your project.

Creating a Vue.js application in Beego

We need to create a route handler in Beego to respond to the Vue.js application. Add the following code to your Beego project:

package controllers

import (
    "github.com/astaxie/beego"
    "fmt"
)

type VueController struct {
    beego.Controller
}

func (c *VueController) Get() {
    c.Data["Website"] = "Vue.js in Beego"
    c.Data["Email"] = "you@example.com"
    c.TplName = "vue.tpl"
}

Here we create a VueController type, which is derived from the beego.Controller type. The Get() method will provide us with a template that responds to the Vue.js application. We will create the vue.tpl template file below.

Create a Vue.js application

Create a directory called views in your Beego project. Create the vue.tpl file in this directory. The following code will give us a simple Vue.js application:

<!DOCTYPE html>
<html>
<head>
    <title>Vue.js in Beego</title>
</head>
<body>
    <div id="app">
        <h2>Welcome to {{ message }}!</h2>
    </div>
    <script src="/static/node_modules/vue/dist/vue.min.js"></script>
    <script>
        var app = new Vue({
            el: '#app',
            data: {
                message: 'Beego and Vue.js'
            }
        })
    </script>
</body>
</html>

In this example, we create a Vue instance and bind it to a div element. The el attribute specifies which element the application is bound to, while the data attribute defines the data object (message).

Note: Since we are using NPM to introduce Vue.js resources, we need to add a static resource directory. Add a directory named static to your Beego project and add the following code to your app.conf configuration file:

[static]
dir = static/

Now, run your Beego application and visit http://localhost:8080/vue, you should see "Welcome to Beego and Vue.js" displayed on your page.

Vue Component

Vue.js component is an important feature of Vue.js, which allows us to create reusable code blocks.

Create a directory called components in your Beego project. Create a Vue component named hello.vue in this directory. Here is a simple Vue component example:

<template>
    <div>
        <h2>{{ title }}</h2>
        <p>{{ message }}</p>
    </div>
</template>

<script>
    export default {
        data() {
            return {
                title: 'Hello',
                message: 'This is a Vue.js component!'
            }
        }
    }
</script>

Next, add the following code in your vue.tpl file to reference your newly created Vue component:

<!DOCTYPE html>
<html>
<head>
    <title>Vue.js in Beego</title>
</head>
<body>
    <div id="app">
        <hello></hello>
    </div>
    <script src="/static/node_modules/vue/dist/vue.min.js"></script>
    <script src="/static/components/hello.vue"></script>
    <script>
        import hello from '/static/components/hello.vue'
        var app = new Vue({
            el: '#app',
            components: { hello }
        })
    </script>
</body>
</html>

In this example, we introduce your Vue component through the import statement and register the component in the components attribute of the Vue instance.

Now access your Beego application and you should see your component displayed on the page with the output message "Hello" and "This is a Vue.js component!".

Summary

In this article, we introduced how to use Vue.js for front-end development in Beego. By using Vue.js components, we can implement reusable code blocks, thereby improving the maintainability and scalability of the code. Vue.js provides powerful and flexible tools to help us build modern web applications. The excellent Beego Vue.js technology combination is a very creative and highly productive choice.
