Issue encountered with Angular 13 and Twilio Sync: The variable name is not recognized as a constructor, resulting in

After upgrading to angular 13, I encountered a problem that was not present when using angular 10.

In my TwilioSyncService, the require statement is included in the constructor because it is an Injectable service requirement.

The code snippet shows how the syncClientclass is instantiated:

export class TwilioSyncService{

  constructor(private http: HttpClient, private router: Router){
    //@ts-ignore
    this.syncClientclass = require('twilio-sync');
  }
  syncClientclass;
  syncClient;

This instance is then used in the following function:

connect(token){
     this.syncClient = new this.syncClientclass(token);
     this.sendSyncClient(this.syncClient);
  }

According to the Twilio Sync documentation, this approach is correct:

var SyncClient = require('twilio-sync');
var syncClient = new SyncClient(token);

You can find more information in the linked documentation.

Answer №1

After updating Twilio Sync to the latest version, I attempted to require it in the same way you did, only to find that I couldn't initialize the client either.

Upon inspecting the required object, I discovered that it was simply an object containing all the classes. In this scenario, you specifically need to access the Client class:

this.syncClientClass = require('twilio-sync').Client;

It seems that your version of twilio-sync may have been updated along with Angular. It appears that this change was introduced in version 3.0.5, bringing about two modifications that could have impacted this issue:

  • Default exports were removed — they were not functional in previous versions either.
  • Resolved type resolution issues in Angular.
