The combination of Vue.js and Elixir language realizes the implementation method of real-time chat and communication applications
Introduction:
In today's Internet era, real-time chat and communication have become indispensable in people's lives and work missing part. In order to achieve high-performance and reliable real-time communication applications, we can combine Vue.js and Elixir languages and take advantage of the advantages of both. This article will introduce how to use the Vue.js front-end framework and Elixir's Phoenix framework to develop a real-time chat and communication application, and provide corresponding code examples.
Part One: Project Overview
Before we begin, let us first understand the basic functions and architecture of the real-time chat and communication application we want to implement.
Part 2: Front-end Implementation
In the front-end part, we will use Vue.js to implement user interaction and data display. First, we need to install Vue.js and its related plug-ins.
Install Vue.js:
Open the terminal and execute the following command to install Vue.js:
$ npm install vue
Create a Vue.js application:
Enter the following command in the terminal to create a new Vue.js application:
$ vue create realtime-chat
Write the Vue component (Chat.vue):
Open src/components
#Chat.vue file in the ## directory, and write the following code:
<template> <div> <h1>实时聊天</h1> <div v-for="(message, index) in messages" :key="index"> {{ message }} </div> <div> <input v-model="inputMessage" type="text" /> <button @click="sendMessage">发送</button> </div> </div> </template> <script> export default { data() { return { messages: [], inputMessage: "", }; }, methods: { sendMessage() { // 调用后端API发送消息 }, }, }; </script>
In the backend part, we Elixir's Phoenix framework will be used to handle real-time communications and backend logic.
Open the terminal and execute the following command to install Elixir and Phoenix:
$ brew install elixir $ mix archive.install hex phx_new
Enter the following command in the terminal to create a new Phoenix application:
$ mix phx.new realtime_chat
Open
lib/realtime_chat_web/channels
chat.ex file in the directory and write the following code:
defmodule RealtimeChatWeb.ChatChannel do use Phoenix.Channel def join("chat:lobby", _params, socket) do {:ok, socket} end def handle_in("new_message", %{"message" => message}, socket) do broadcast(socket, "new_message", %{message: message}) {:noreply, socket} end end
Open
lib/realtime_chat_web router.ex
file in the /router directory, and then add the following code:
defmodule RealtimeChatWeb.Router do use RealtimeChatWeb, :router # ... channel "chat:*", RealtimeChatWeb.ChatChannel end
Now we have Completed the basic code of the front and back ends. Next, we need to implement front-end and back-end communication to implement the real-time chat function.
Open the
src/main.js file and add the following code:
import Vue from "vue"; import App from "./App.vue"; import Phoenix from "phoenix"; Vue.config.productionTip = false; const socket = new Phoenix.Socket("/socket", {}); socket.connect(); Vue.prototype.$socket = socket; new Vue({ render: (h) => h(App), }).$mount("#app");
Modify the
sendMessage method and
data attribute of the
Chat.vue file, To implement the functionality of sending and receiving real-time messages:
methods: { sendMessage() { this.$socket.channel("chat:lobby").push("new_message", { message: this.inputMessage }); this.inputMessage = ""; }, }, created() { const channel = this.$socket.channel("chat:lobby"); channel.on("new_message", (payload) => { this.messages.push(payload.message); }); channel.join().receive("ok", (response) => { console.log("成功加入聊天室"); }); },
Now we can run our real-time chat and messaging application.
Enter the following command in the terminal to start the Elixir service:
$ cd realtime_chat $ mix phx.server
In another terminal window, navigate to the root directory of the Vue.js application and execute the following command:
$ cd realtime-chat $ npm run serve
, you should be able to see the live chat interface.
This article introduces how to use Vue.js and Elixir's Phoenix framework to develop real-time chat and communication applications. The front-end Vue.js framework realizes user interaction and data display, and the back-end Elixir language and Phoenix framework realize real-time communication and back-end logic. I hope this article was helpful and inspired you with ideas for developing more real-time messaging apps.
