Changes in 4.x (and how to migrate!)

Hello dear reader, thank you for adopting version 4.x of the MongoDB Node.js driver, from the bottom of our developer hearts we thank you so much for taking the time to upgrade to our latest and greatest offering of a stunning database experience. We hope you enjoy your upgrade experience and this guide gives you all the answers you are searching for. If anything, and we mean anything, hinders your upgrade experience please let us know via JIRA. We know breaking changes are hard but they are sometimes for the best. Anyway, enjoy the guide, see you at the end!

Key Changes

Typescript

We've migrated the driver to Typescript! Users can now harness the power of type hinting and intellisense in editors that support it to develop their MongoDB applications. Even pure JavaScript projects can benefit from the type definitions with the right linting setup. Along with the type hinting there's consistent and helpful docs formatting that editors should be able to display while developing. Recently we migrated our BSON library to TypeScript as well, this version of the driver pulls in that change.

Community Types users (@​types/mongodb)

If you are a user of the community types (@​types/mongodb) there will likely be compilation errors while adopting the types from our codebase. Unfortunately we could not achieve a one to one match in types due to the details of writing the codebase in Typescript vs definitions for the user layer API along with the breaking changes of this major version. Please let us know if there's anything that is a blocker to upgrading on JIRA.

Node.js Version

We now require node 12.9 or greater for version 4 of the driver. If that's outside your support matrix at this time, that's okay! Bug fix support for our 3.x branch will not be ending until summer 2022, which has support going back as far as Node.js v4!

CRUD results

Our CRUD operations now return the drivers-wide spec-compliant results which are defined here:

• CRUD SPEC Write Results

For example, insertOne() used to return an object that was shaped like:

interface LegacyInsertOneResult {
    insertedCount: number;
    ops: InsertedDocument[];
    insertedId: ObjectId;
    connection: Connection;
    result: { ok: number; n: number };
}

and now returns:
