TypeScript Strict Mode Errors After Refactoring

After enabling or upgrading TypeScript strict mode, Cursor's refactored code now has many type errors. The strict rules catch null/undefined issues and type mismatches that were previously ignored.

Code needs proper typing to satisfy strict mode requirements.

Error Messages You Might See

Object is possibly 'null' Type 'any' is not assignable Property does not exist on type Argument of type 'unknown' not assignable
Object is possibly 'null'Type 'any' is not assignableProperty does not exist on typeArgument of type 'unknown' not assignable

Common Causes

  1. Variables not initialized, inferred as 'any' type
  2. Null/undefined not handled, accessing properties on potentially null values
  3. Function return type not specified
  4. Parameters not typed, defaulting to 'any'
  5. Using 'any' type to bypass checks

How to Fix It

Add types: const value: string = 'hello'. Function returns: function getName(): string { }. Handle null: value?.property || default. Use NonNullAssert if sure: value!. Enable strict in tsconfig: "strict": true.

Frequently Asked Questions

What does !mean in TypeScript?

Non-null assertion operator. Tells compiler you know value isn't null. Use sparingly - usually fix the root cause.

How do I fix 'possibly null' errors?

Add null check: if (value) { ... }. Or optional chaining: value?.property. Or default: value || defaultValue.
