Issue: Avoid Using any Type for MONGODB_URI in connectDB

Open Uneebbhat opened this issue 7 months ago • 0 comments

FIle: db.config.ts

Description: The connectDB function currently accepts MONGODB_URI with the type any: export const connectDB = (MONGODB_URI: any) => {}

Using any defeats the purpose of TypeScript’s static type checking and may lead to unexpected runtime behavior. Since MONGODB_URI is expected to be a connection string, the appropriate type should be string.

Recommended Fix Change the function signature to: export const connectDB = (MONGODB_URI: string) => { ... } This improves type safety and aligns with TypeScript best practices.

Benefit

  • Enforces type correctness
  • Prevents runtime errors
  • Improves code readability and maintainability

Additional Suggestion To prevent errors from an empty or undefined connection string, introduce a guard clause: if (!MONGODB_URI || MONGODB_URI.trim() === "") { throw new Error("MONGODB_URI is required and must be a non-empty string."); }
