Vue3 + OpenLayers 企业级应用进阶

1. 企业级架构设计

1.1 微前端架构集成

import { Map } from 'ol';
import { registerMicroApps, start } from 'qiankun';export class MapMicroFrontend {private map: Map;private apps: any[];constructor(map: Map) {this.map = map;this.apps = [];this.initMicroFrontend();}private initMicroFrontend() {registerMicroApps([{name: 'map-analysis',entry: '//localhost:7100',container: '#map-analysis-container',activeRule: '/map/analysis'},{name: 'map-editor',entry: '//localhost:7101',container: '#map-editor-container',activeRule: '/map/editor'}]);start();}// 注册子应用registerApp(app: any) {this.apps.push(app);}// 获取地图实例getMapInstance(): Map {return this.map;}
}

1.2 状态管理优化

// src/store/map-store.ts
import { defineStore } from 'pinia';
import { Map } from 'ol';
import { Feature } from 'ol';
import { Geometry } from 'ol/geom';export const useMapStore = defineStore('map', {state: () => ({map: null as Map | null,selectedFeatures: [] as Feature<Geometry>[],mapState: {zoom: 0,center: [0, 0],rotation: 0}}),actions: {setMap(map: Map) {this.map = map;},setSelectedFeatures(features: Feature<Geometry>[]) {this.selectedFeatures = features;},updateMapState() {if (this.map) {const view = this.map.getView();this.mapState = {zoom: view.getZoom() || 0,center: view.getCenter() || [0, 0],rotation: view.getRotation() || 0};}}}
});

2. 企业级性能优化
