MERN-template VS MongoDB

Anyway, the structure of this website uses microservices, driven by an engine I dubbed the MERN-template. It has it's own auth service, and supports both chat and a news feed. The game-specific elements are closed-source though (the idea is you fork the core repo, and build out from there).

i use mariadb, but yes.

Backstory: Decade Jam, a game jam that lasts for a decade, began Jan 1st, 2020. I started writing a web game called Egg Trainer, but after a year of work realized that my codebase wasn't workable anymore. So at the beginning of 2021, I began working on a game engine that would power the beta version of ET - this is called the MERN-template (clearly, I'm bad at naming things).

My MERN-template actually uses MySQL. There's no requirement that you do it one specific way.

I'd use the MERN-template project that I wrote myself. It's essentially the mern stack, except with MySQL.

I've basically written this thing from the ground up, including an open source engine that uses microservices.

Anyway here's my game engine.

Oh, I've done this with my MERN-template. It was designed to power my game, but I made it available for others to use.

The MongoDB JavaScript driver uses and requires node.js, which is what 99.9% of server-side JavaScript implementations use.

Mongo Drivers

If you look at how major backend projects structure their code, it's almost always object-oriented TypeScript.

I submit for the record:

The MongoDB Node.js Driver, to save data to MongoDB;

The error probably is a MongoServerError, not MongoError, see https://github.com/mongodb/node-mongodb-native/blob/HEAD/etc/notes/errors.md

The most basic way to interact with MongoDB is using the Official MongoDB Node.js Driver, in this guide we will use Mongoose an object modeling tool.

Now when you use the collection, you'll get better type support for for all the collection methods. Note that I had to make the _id required on the schema. If you make it optional, you still get a type error. The node driver team is working on this and other issues related to the type of _id in this PR: https://github.com/mongodb/node-mongodb-native/pull/3077

To communicate with MongoDB database we will need Node driver mongodb. So install it.

Could this _ensureIndex be the problem? I think that may be calling into listIndexes here: https://github.com/mongodb/node-mongodb-native/blob/2b18411d2f57e06d11262d5a308c56a9f561789e/lib/operations/db_ops.js#L305. IIRC, ensureIndex is deprecated, and you should use createIndex instead. I'm not familiar with meteor, so I'm not exactly sure what that code looks like, but the README shows how to access the underlying MongoDB driver directly: https://github.com/meteor/meteor/tree/devel/packages/mongo#direct-access-to-npm-mongodb-api. Hope that helps!
