The combination of Vue.js and Elixir language realizes the implementation method and development experience of real-time chat and communication applications

Introduction

With the development of the Internet, real-time communication and chat applications are becoming part of people's daily lives. Real-time messaging applications can achieve instant messaging and interaction, and Vue.js and Elixir, as a popular web development framework and a powerful programming language, can well support and realize this need. This article will introduce the basic concepts of Vue.js and Elixir, and give development examples of real-time chat and communication applications.

Introduction to Vue.js

Vue.js is a lightweight JavaScript framework focused on building user interfaces. It adopts the MVVM (Model-View-ViewModel) pattern, allowing developers to efficiently build highly interactive applications through data-driven and componentized methods. Vue.js has a concise API and rich functionality that integrates well with other front-end tools and libraries.

Elixir introduction

Elixir is a functional programming language based on the Erlang virtual machine, which has a high degree of scalability and concurrency capabilities. Elixir was first proposed to build reliable and efficient distributed systems. It helps developers easily build reliable and concurrent applications through features such as Actor model and hot code replacement.

The principle of combining Vue.js and Elixir

Vue.js and Elixir can communicate through RESTful API or Websocket. In the front-end and back-end separated architecture, Vue.js is responsible for front-end interaction logic and UI rendering, while Elixir is responsible for back-end business logic and data processing. Through this layered design and data interaction, decoupling and efficient collaboration between the front and back ends are achieved.

Development of real-time chat and communication applications

The following takes a simple real-time chat application as an example to introduce the application of the combination of Vue.js and Elixir in real-time communication applications.

First, create the Elixir backend application. Use the Phoenix framework to build a simple chat server.

# lib/chat.ex
defmodule Chat do
  use Phoenix.Channel

  def join("chat:lobby", _message, socket) do
    {:ok, socket}
  end

  def handle_in("new_msg", %{"body" => body}, socket) do
    broadcast! socket, "new_msg", %{body: body}
    {:noreply, socket}
  end
end

In Phoenix, we created a channel called "chat" and implemented the logic of joining the chat room and receiving new messages on the "chat:lobby" channel.

Next, create a Vue.js front-end application. Use Vue.js to develop front-end chat interface and real-time communication logic.

<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Chat</title>
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <div id="app">
    <h2 id="Chat-Room">Chat Room</h2>
    <div id="chat-box">
      <div v-for="message in messages">
        <strong>{{ message.body }}</strong>
      </div>
    </div>
    <input v-model="newMessage" @keyup.enter="sendMessage" placeholder="Type your message here...">
  </div>
  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
  <script src="app.js"></script>
</body>
</html>

// app.js
new Vue({
  el: '#app',
  data: {
    messages: [],
    newMessage: ''
  },
  created() {
    // Connect to Phoenix socket
    let socket = new Socket("/socket", {params: {token: 'your_auth_token'}})
    socket.connect()

    // Create a Phoenix channel
    let channel = socket.channel("chat:lobby", {})

    // Join the channel
    channel.join()
      .receive("ok", resp => {
        console.log("Joined successfully", resp)
      })
      .receive("error", resp => {
        console.log("Unable to join", resp)
      })

    // Listen for new messages
    channel.on("new_msg", message => {
      this.messages.push(message)
    })

    // Assign the channel to Vue data
    this.$data.channel = channel
  },
  methods: {
    sendMessage() {
      if (this.newMessage.trim() !== '') {
        // Send the message to the Phoenix channel
        this.channel.push("new_msg", {body: this.newMessage})

        // Clear the input field
        this.newMessage = ''
      }
    }
  }
})

In the above code, we use Vue.js to implement the chat interface and the logic of sending messages. During the Vue instance creation process, we created a Socket to communicate with the Phoenix framework, then created a channel named "chat:lobby" and joined the channel. Next, we listen for the "new_msg" event on this channel and push the new message to the message list.

Conclusion

By combining Vue.js with Elixir, we can efficiently build real-time chat and communication applications. Vue.js is responsible for real-time rendering and user interaction, while Elixir is responsible for handling background business and data transmission. Through this method of front-end and back-end separation and data interaction, we can easily implement complex real-time communication and chat applications. If you are building such an application, you might as well try the combination of Vue.js and Elixir to experience its powerful functions and excellent development experience.
