Why is mongoose typed so loosely?

• Mongoose

  108 26,598 10.0 JavaScript

  MongoDB object modeling designed to work in an asynchronous environment.

  

Never used it personally. But just having a quick look at their github project...

• MikroORM

  48 7,122 9.9 TypeScript

  TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns. Supports MongoDB, MySQL, MariaDB, MS SQL Server, PostgreSQL and SQLite/libSQL databases.

  

I ended up writing my own ORM (it's a wrapper over Knex). But if I had to pick something off-the-shelf, the next one I'd probably try is https://mikro-orm.io/

• SurveyJS

  surveyjs.io sponsored

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  

• papr

  4 417 9.4 TypeScript

  MongoDB TypeScript-aware Models

  

I also think the typescript support for mongoose leaves much to be desired. A few months ago, papr catched my eye, which looked like it was created from the lack of typesafe ORMs/ODMs for mongoDB.

• vite

  785 64,595 9.9 TypeScript

  Next generation frontend tooling. It's fast!

  

I also came to the conclusion that mongoose lacks good TypeScript support. I recently have tried papr, that makes a few things better, but it also isn't as typesafe as I wanted it to be. It also didn't work with our vite setup. I got plenty of errors when running the dev server. We now are using papr to https://plexinc.github.io/papr/#/schema?id=schema-updates

• Prisma

  442 37,151 9.9 TypeScript

  Next-generation ORM for Node.js & TypeScript | PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB and CockroachDB

  

We’ve been using prisma a lot lately, very happy with it’s typescript support.

• Superstruct

  26 6,802 5.7 TypeScript

  A simple and composable way to validate data in JavaScript (and TypeScript).

After switching to TS, I found mongoose (and alternatives like ts-mongoose) not very useful. Depending on how many of mongoose's features you're using, I found it much easier to use the MongoDb Driver directly which already has a fluent ORM-like API and it's typed very well, and then you can use something like superstruct if you need schema validation
