This Skill solves inconsistent and risky MongoDB usage in Node.js codebases by enforcing a clean Mongoose architecture that prevents connection explosions and slow, unindexed queries.
mongoose.connect() in src/lib/db.ts and reuses the cached connection to avoid exhausting MongoDB connection limits.src/models/ and moves query logic into src/repositories/, with services validating input before repository calls..lean() for read queries where document methods aren’t needed, requires appropriate schema indexes for frequently queried fields, and mitigates NoSQL injection by validating inputs (e.g., ObjectId format).mongoose.connect() and queries are scattered across models. Use this Skill to reorganize into src/lib, src/models, src/repositories, and src/services while standardizing .lean(), .populate(), and indexed schema fields.Tell your agent: “Apply the Mongoose architecture rules to my repository: enforce a single cached MongoDB connection in src/lib/db.ts, move schema/model code into src/models, move queries into src/repositories using .lean() and .populate() appropriately, and ensure inputs are validated at the service boundary to prevent NoSQL injection.”

To prevent MongoDB connection exhaustion, standardize a single cached `mongoose.connect()` call in `src/lib/db.ts` and reuse that connection across all API routes and background jobs, avoiding multiple connection instances.
The best way to structure Mongoose ODM queries is to separate schema definitions into `src/models/` and move all query logic into `src/repositories/`, with services handling input validation before calling repository methods.
To mitigate NoSQL injection risks with Mongoose, enforce explicit input validation at the service boundary, such as checking ObjectId formats, before passing user input to repository query methods.
You need to use `.lean()` in Mongoose read queries when document methods are not required, as it returns plain JavaScript objects instead of full Mongoose documents to significantly improve read performance.
Yes, this Mongoose architecture refactoring approach applies to both JavaScript and TypeScript codebases, standardizing connection lifecycle, model/repository separation, and schema indexes safely across both environments.
