classAssignments

Reports reassigning class declarations.

✅ This rule is included in the ts javascript presets.

Reassigning a class declaration can lead to unexpected behavior and makes code harder to understand. Class declarations are typically intended to be immutable references, and reassigning them can cause confusion about which class is being used.

class 
class MyClass
MyClass {}
class MyClass
MyClass = 0;

class 
class Counter
Counter {}
class Counter
Counter++;

class 
class Data
Data {}
class Data
Data = null;

class 
class MyClass
MyClass {}
const 
const instance: MyClass
instance = new 
constructor MyClass(): MyClass
MyClass();

class 
class Counter
Counter {}
const 
const value: typeof Counter
value = 
class Counter
Counter;

class 
class MyClass
MyClass {}
const 
const derived: typeof derived
derived = class extends 
class MyClass
MyClass {};

This rule is not configurable.

When Not To Use It

If your project uses class reassignments as a design pattern, you might not be able to immediately enable this rule. Consider using differently-named variables instead to gain mutable references to classes.
