Utilize the power of meteor-dburles-collection-helpers in TypeScript for optimizing your collections

Currently, I am utilizing the dburles:collection-helpers in my Meteor 2.12 project that is integrated with TypeScript. The package was included through

meteor add dburles:collection-helpers
, and the types were added using
meteor yarn add @types/meteor-dburles-collection-helpers
.

Within my TypeScript file:

import { Mongo } from "meteor/mongo";
import SimpleSchema from 'simpl-schema';
...
interface IBackupJobs {
  status: "queued" |
      "in_progress" |
      "restarting" |
      "finished_ok" |
      "finished_error"
...
}

const BackupJobsSchema = new SimpleSchema({
  status: {
    type: String,
    allowedValues: [
      "queued",
      "in_progress",
      "restarting",
      "finished_ok",
      "finished_error"
    ]
  },
...
});
const BackupJobs = new Mongo.Collection<IBackupJobs>("backup_jobs");
BackupJobs.attachSchema(BackupJobsSchema);
BackupJobs.helpers({
  isRunning() {
    return (
      this.status === "queued" ||
      this.status === "in_progress" ||
      this.status === "restarting"
    );
  }
});

However, I have encountered an error in my IDE pointing to BackupJobs.helpers: Property 'helpers' does not exist on type Collection<Document, Document>

I attempted to place the types files from

meteor-dburles-collection-helpers
within my custom typings-custom project folder, but the error persisted.

Does anyone have any suggestions?

Answer №1

By including the line

import 'meteor-dburles-collection-helpers'
, the issue can be resolved. However, it is necessary to append an additional property called isRunning to the IBackupJobs interface. The updated interface definition is as follows:

interface IBackupJobs {
  status: "queued" |
      "in_progress" |
      "restarting" |
      "finished_ok" |
      "finished_error"
...
  isRunning: () => boolean
}
