Error message in Typescript: The 'new' keyword cannot be used with an expression that does not have a call or construct signature

Encountered an issue while trying to establish a connection with the PouchDB Database.

An error message states: Typescript Cannot use 'new' with an expression whose type lacks a call or construct signature

Shown below is the code snippet in question:-

var PouchDB = require("pouchdb"); 

@Injectable()
export class PouchDBService {

  private isInstantiated: boolean;
  private database: any;

  public constructor(private http: Http) {
    if(!this.isInstantiated) {

      this.database = new PouchDB("db_name"); <--issue arises here
      this.isInstantiated = true;
    }

Answer №1

@types/pouchdb could offer some assistance in this situation.

Answer №2

If you're looking to use pouchdb, you can do so by following these steps:

import * as PouchDB from "pouchdb";

After importing, you can initialize a new database like this:

this.database = new PouchDB("db_name"); //this code should function correctly
