The current @types/meteor package sets a dependency to
"mongodb": "^4.3.1"
However, since Meteor 3.1, Meteor uses mongodb 6.10.0 / 6.9.0:
This becomes noticable when you use db.rawCollection() and methods like db.collection.findOneAndUpdate() which changed its result type since mongodb 5.x.
I also stumbled upon this when I wanted to use agenda in combination with Meteor. Since @types/meteor pulls in mongodb@4.17.2 which itself sets a dependency on bson@4.7.2, agenda tries to use bson@4.7.2 as well, which is incompatible with Meteor’s current bson@6.10.4, causing runtime errors. I had to fix this by pulling in mongodb@6.21.0 on top-level, which is an ugly workaround.
Proposed solution: Add a new major for @types/meteor that sets a dependeny to mongodb@^6.9.0.
I opened an issue in the @types repository:
but I thought I’d copy this note here. Maybe someone in the Meteor team wants to check this.
