Production Risk
Build will fail; resolve before shipping.
What this means
A TypeScript diagnostic (TS95040): Implement all inherited abstract classes. This diagnostic is emitted by the TypeScript compiler when implement all inherited abstract classes.
Why it happens
- 1A concrete class extends an abstract class but does not implement all abstract members
How to reproduce
TypeScript compiler reports TS95040 during type checking.
trigger — this will error
trigger — this will error
// Triggers TS95040 // Implement all inherited abstract classes
expected output
error TS95040: Implement all inherited abstract classes
Fix
Implement all abstract members
WHEN Extending an abstract class
Implement all abstract members
abstract class Base {
abstract doWork(): void;
}
class Derived extends Base {
doWork(): void { /* implementation */ }
}Why this works
All abstract members must be implemented in concrete subclasses.
