TypeScript for aldeed:collection2: Cannot find name 'Collection2'.ts(2304)

packages
1

The README for collection2 says to add the below lines but when I do, I get the TypeScript issue Cannot find name 'Collection2'.ts(2304).

How do I set this package up with TypeScript?

import 'meteor/aldeed:collection2/dynamic';

Collection2.load();

This package doesn’t have type definition. I think you can manually define types for that one or just ignore it.

How do I define my own types for it?

4

by creating a .d.ts file (anywhere inside your project) for example /import/types/collection2.d.ts
It will look like this:

declare namespace Collection2 {
  function load(): void;
}

// just the idea, I don’t think it works without any bug.

Thanks! That fixed it for me!

Do you also know how to fix the attachSchema is not a function error?

try this:

import { NpmModuleMongodb } from 'meteor/npm-mongo';
import { SimpleSchema } from 'meteor/aldeed:simple-schema';

declare module 'meteor/mongo' {
  namespace Mongo {
    interface Collection<T extends NpmModuleMongodb.Document, U = T> {
      attachSchema(schema: SimpleSchema): void;
    }
  }
}
