What is the best way to save the output of the services function as an array of objects in a separate TypeScript file?

I need to store the result of a function in my services into an array of objects in my TypeScript file.

getserver(id:number) {
    const server = this.servers.find(
      (s) => {
        return s.id === id;
      }
    )
  }

The return type of this function is void, but I want to store it as an object in my TypeScript file and I'm encountering an error:

*Error type void is not assignable to type {id:number,name:string,status:string}[];

My question is what am I doing wrong? Do I need to convert the void return type into an object somehow? If so, how can I do that?

edit-server.ts

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { ServerService } from '../../servers.service';

@Component({
  selector: 'app-edit-server',
  templateUrl: './edit-server.component.html',
  styleUrls: ['./edit-server.component.css']
})
export class EditServerComponent implements OnInit {
  servers!: {id:number,name:string,status:string}[];
  constructor(private route: ActivatedRoute, private serviceserv: ServerService) { }
 
  serverName = '';
  serverStatus = '';
  ngOnInit(): void {
    
   this.servers= this.serviceserv.getserver(2);


  }
  onupdate() {
  
   this.serviceserv.updateserver(this.servers.id, {name:this.serverName,status:this.serverStatus});
  }

}

server.service.ts

import { Injectable } from '@angular/core';
@Injectable({ providedIn: 'root' })
export class ServerService {
  
   servers = [
    {
      id: 1,
      name: 'ProductionServer',
      status:'online'
    },
    {
      id: 2,
      name: 'TestServer',
      status: 'online'
    },
    {
      id: 3,
      name: 'DevServer',
      status: 'offline'
    }
  ];
  getservers() {
    return this.servers;
  }
  getserver(id:number) {
    const server = this.servers.find(
      (s) => {
        return s.id === id;
      }
    )
    console.log(server!.id);
   
  }
  updateserver(id: number, serverInfo: { name: string, status: string }) {
    const server = this.servers.find(
      (s) => {
        return s.id === id;
      }
    );
    if (server) {
      server.name = serverInfo.name;
      server.status = serverInfo.status;
    }

  }

}

Answer №1

  When retrieving a server by ID, consider using the following approach:

getServer(id: number) { 
    return this.servers.find((s) => s.id === id);
}

Alternatively, you could also do:

getServer(id: number) { 
    const server = this.servers.find((s) => s.id === id);
    
    return server;
}
