oxc/no-redundant-constructor-init Correctness

✅ This rule is turned on by default.

🚧 An auto-fix is still under development.

What it does

Prevents redundant initialization of class members within a constructor.

Why is this bad?

Arguments marked as public within a constructor are automatically initialized. Providing an explicit initialization is redundant and can be removed.

Examples

Examples of incorrect code for this rule:

class Foo {
  constructor(public name: unknown) {
    this.name = name;
  }
}

Examples of correct code for this rule:

class Foo {
  constructor(public name: unknown) {}
}

How to use

To enable this rule in the CLI or using the config file, you can use:

CLI

Config (.oxlintrc.json)

  "rules": {
    "oxc/no-redundant-constructor-init": "error"
