将Angular与Neo4j集成可以创建强大的全栈应用程序,利用Neo4j的图数据库功能和Angular的前端框架。以下是一些参考站点和材料,可以帮助你开始这项工作:
以下是一个简单的示例,展示了如何在Angular应用中使用Neo4j JavaScript驱动:
npm install neo4j-driver
import { Injectable } from '@angular/core'; import * as neo4j from 'neo4j-driver'; @Injectable({ providedIn: 'root' }) export class Neo4jService { private driver; constructor() { this.driver = neo4j.driver('bolt://localhost:7687', neo4j.auth.basic('username', 'password')); } async runQuery(query: string, params: any = {}) { const session = this.driver.session(); try { const result = await session.run(query, params); return result.records; } finally { await session.close(); } } }
import { Component, OnInit } from '@angular/core';
import { Neo4jService } from './neo4j.service';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
title = 'neo4j-angular';
constructor(private neo4jService: Neo4jService) {}
ngOnInit() {
this.neo4jService.runQuery('MATCH (n) RETURN n LIMIT 10').then(records => {
console.log(records);
});
}
}
