How to combine jsmind in a Vue project to achieve real-time sharing and collaborative editing of mind maps?

Mind mapping is a very effective tool that can help us organize and express our thinking. With the popularity of Vue, it has become possible to combine Vue and the jsmind library to achieve real-time sharing and collaborative editing of mind maps. In this article, we will introduce how to use the jsmind library in a Vue project to create mind maps and achieve real-time sharing and collaborative editing.

First, we need to install the jsmind library in the Vue project. You can use npm or yarn to install jsmind:

npm install jsmind --save

or

yarn add jsmind

After the installation is complete, we need to introduce the jsmind library into the Vue component.

import jsMind from 'jsmind';
import 'jsmind/style/jsmind-default.css';

Next, we need to initialize jsmind in Vue's life cycle function and create a mind map.

mounted() {
  const jsmindContainer = this.$refs.jsmindContainer;
  const mindMap = {
    "meta": {
      "name": "思维导图",
      "author": "你的名字",
      "version": "1.0"
    },
    "format": "node_array",
    "data": [
      {"id":"root","isroot":true,"topic":"主题"}
    ]
  };
  this.jsMindInstance = new jsMind(jsmindContainer, mindMap);
},

In the above code, we first obtain the container element jsmindContainer, and then create a jsmind instance based on the mind map data we defined.

Now, we have successfully created a mind map. Next, let’s implement real-time sharing and collaborative editing.

In order to achieve real-time sharing and collaborative editing, we need to use WebSocket to establish a real-time communication connection. Assume that we have set up a WebSocket server and can connect to the server through ws://localhost:8080.

In the Vue component, we can use the vue-native-websocket library to initialize the WebSocket connection.

First, we need to install the vue-native-websocket library:

npm install vue-native-websocket --save

or

yarn add vue-native-websocket

Next, in Vue’s main. In the js file, we need to introduce the vue-native-websocket library and configure the WebSocket connection.

import VueNativeSock from 'vue-native-websocket';

Vue.use(VueNativeSock, 'ws://localhost:8080', {
  format: 'json',
  reconnection: true,
  reconnectionAttempts: 5,
  reconnectionDelay: 3000
});

In the above code, we initialize a WebSocket connection and bind it to VueNativeSock. At the same time, we also specified the server's address and some connection configuration.

Next, in the Vue component, we can use this.$socket to access the WebSocket connection for real-time sharing and collaborative editing.

methods: {
  handleMindMapUpdate(data) {
    this.jsMindInstance.show(data);
  }
},
sockets: {
  mindMapUpdate(data) {
    this.handleMindMapUpdate(data);
  }
},

In the above code, we define a mindMapUpdate event. When the server sends the event, we will call the handleMindMapUpdate method to update the mind map.

The complete Vue component code is as follows:

<template>
  <div ref="jsmindContainer"></div>
</template>

<script>
import jsMind from 'jsmind';
import 'jsmind/style/jsmind-default.css';

export default {
  mounted() {
    const jsmindContainer = this.$refs.jsmindContainer;
    const mindMap = {
      "meta": {
        "name": "思维导图",
        "author": "你的名字",
        "version": "1.0"
      },
      "format": "node_array",
      "data": [
        {"id":"root","isroot":true,"topic":"主题"}
      ]
    };
    this.jsMindInstance = new jsMind(jsmindContainer, mindMap);
  },
  methods: {
    handleMindMapUpdate(data) {
      this.jsMindInstance.show(data);
    }
  },
  sockets: {
    mindMapUpdate(data) {
      this.handleMindMapUpdate(data);
    }
  }
};
</script>

In the above code, we pass the container element div of the mind map through ref The property is bound to jsmindContainer and a jsmind instance is created in the mounted life cycle function.

Finally, we need to implement the functions of real-time sharing and collaborative editing of mind maps in the WebSocket server. When a new mind map data is received, we need to broadcast it to all clients connected to the server.

The following is a sample code for a simple Node.js WebSocket server:

const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', (ws) => {
  ws.on('message', (data) => {
    // 接收到新的思维导图数据
    // 广播给所有连接到服务器的客户端
    wss.clients.forEach((client) => {
      if (client.readyState === WebSocket.OPEN) {
        client.send(data);
      }
    });
  });
});

In the above code, we iterate through all the clients connected to the WebSocket server and when new ideas are received When mapping data, send it to all clients.

Through the above code examples, we can combine jsmind in the Vue project to realize the real-time sharing and collaborative editing functions of mind maps. Real-time communication through WebSocket allows multiple users to edit and view the same mind map at the same time, greatly improving team collaboration efficiency.
