As part of MONGOSH-538, we will be generating TS definitions for MQL, and in particular aggregation stages, based on the PHP driver's YAML files. Since the Node.js driver generally aims to provide helpful TS definitions, it could make use of these files as well once they exist.

Use Case

As a... Node.js driver user
I want... nice autocompletions for agg pipelines
So that... writing agg pipelines is less intimidating/challenging

User Experience

Users will receive the guidance TS typically provides not just for basic MQL, but also aggregation pipelines in general.

Dependencies

Depends on MONGOSH-538.

Risks/Unknowns

The PHP driver's YAML definitions aren't very strictly typed. We'll need to investigate this on the DevTools end as well.
The additional TS is large and could impact processing/build times.

Acceptance Criteria

Implementation Requirements

• functional reqs, potential snafus to avoid, performance targets, etc

Testing Requirements

• unit test, spec test sync, etc

Documentation Requirements

• DOCSP ticket, API docs, etc

Follow Up Requirements

• additional tickets to file, required releases, etc
• if node behavior differs/will differ from other drivers, confirm with dbx devs what standard to aim for and what plan, if any, exists to reconcile the diverging behavior moving forward
