Building a personalized brain mapping tool: a combined application of PHP and Vue

With the explosive growth of information, people increasingly need a tool that can help organize and Tools for organizing your thinking. As an effective tool, mind mapping has been widely used in many scenarios such as knowledge organization, project management, and meeting notes. This article will introduce how to build a personalized mind mapping tool through PHP and Vue.

1. Technology Selection

Before we start building a personalized brain mapping tool, we need to choose the appropriate technology to implement it. Since mind maps usually need to be displayed and interacted on the front end, and the back end is responsible for processing data and business logic, we chose PHP as the back-end language and Vue as the front-end framework.

PHP is a back-end language widely used in web development. It is easy to learn, has clear syntax, and is highly scalable. Vue is a modern front-end framework with the characteristics of componentization and responsive design, which can help us quickly build complex interactive interfaces.

2. Separated architecture of front-end and back-end

Since the brain mapping tool needs to be developed separately from the front-end and back-end, we can use RESTful API for data communication between the front-end and back-end. Specifically, the front-end requests the back-end API interface through Ajax to obtain data and display and operate it.

On the backend, we need to create a series of API interfaces to handle front-end requests. Specifically, operations include creating, updating, and deleting brain map nodes. The design of these interfaces needs to be determined based on actual needs to meet the individual needs of users. The following is a simple sample code:

<?php

// 创建脑图节点
function createNode($data) {
    // 处理创建节点的逻辑
}

// 更新脑图节点
function updateNode($id, $data) {
    // 处理更新节点的逻辑
}

// 删除脑图节点
function deleteNode($id) {
    // 处理删除节点的逻辑
}

// 通过路由来判断请求类型和具体的操作
$method = $_SERVER['REQUEST_METHOD'];
switch ($method) {
    case 'POST':
        $data = $_POST;
        createNode($data);
        break;
    case 'PUT':
        $id = $_GET['id'];
        $data = $_POST;
        updateNode($id, $data);
        break;
    case 'DELETE':
        $id = $_GET['id'];
        deleteNode($id);
        break;
    default:
        // 其他请求类型的处理
        break;
}

3. Data storage and persistence

In order to persistently store brain map data, we can choose to use a relational database or NoSQL database. Specific choices can be determined based on needs and technology stack. In this article, we choose to use MySQL as the data storage solution.

In MySQL, we can create a table with a parent-child relationship to store brain map nodes. The table structure can be as follows:

CREATE TABLE `node` (
    `id` INT NOT NULL AUTO_INCREMENT,
    `parent_id` INT,
    `name` VARCHAR(255) NOT NULL,
    `content` TEXT,
    PRIMARY KEY (`id`)
);

In PHP, we can use PDO or other ORM tools to perform database operations. The following is a simple sample code:

// 初始化数据库连接
$db = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'username', 'password');

// 创建脑图节点
function createNode($data) {
    global $db;
    // 处理创建节点的逻辑，执行插入操作
    $sql = "INSERT INTO `node` (`parent_id`, `name`, `content`) VALUES (:parent_id, :name, :content);";
    $stmt = $db->prepare($sql);
    $stmt->execute($data);
    // 返回新创建节点的 id
    return $db->lastInsertId();
}

// 更新脑图节点
function updateNode($id, $data) {
    global $db;
    // 处理更新节点的逻辑，执行更新操作
    $sql = "UPDATE `node` SET `parent_id` = :parent_id, `name` = :name, `content` = :content WHERE `id` = :id;";
    $stmt = $db->prepare($sql);
    $stmt->bindParam(':id', $id);
    $stmt->execute($data);
}

// 删除脑图节点
function deleteNode($id) {
    global $db;
    // 处理删除节点的逻辑，执行删除操作
    $sql = "DELETE FROM `node` WHERE `id` = :id;";
    $stmt = $db->prepare($sql);
    $stmt->bindParam(':id', $id);
    $stmt->execute();
}

4. Front-end display and interaction

On the front-end, we can use Vue to create a responsive mind map interface. Vue's componentization and responsive design can help us implement complex interactive logic and data display.

The following is a simple Vue component sample code:

<template>
  <div>
    <div v-for="node in nodes" :key="node.id">
      <span>{{ node.name }}</span>
      <button @click="deleteNode(node.id)">删除</button>
    </div>
    <button @click="createNode()">新建节点</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      nodes: [],
    };
  },
  methods: {
    createNode() {
      // 发送 Ajax 请求到后端创建节点
      // 刷新页面或者局部更新节点列表
    },
    deleteNode(id) {
      // 发送 Ajax 请求到后端删除节点
      // 刷新页面或者局部更新节点列表
    },
  },
  mounted() {
    // 发送 Ajax 请求获取节点列表
    // 更新节点列表
  },
};
</script>

Through the above code sample, we can see how to use PHP and Vue to implement a personalized mind mapping tool. Through the front-end and back-end separation architecture, reasonable data storage and persistence solutions, and flexible front-end display and interaction logic, we can build a powerful brain mapping tool to help people better organize and sort out their thinking.
