Issue: Avoid Using any Type for MONGODB_URI in connectDB

[Uneebbhat]

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."); }
