eslint/no-useless-constructor Suspicious
What it does
Disallow constructors that can be safely removed without changing how the class works.
Why is this bad?
ES2015 provides a default class constructor if one is not specified. As such, it is unnecessary to provide an empty constructor or one that simply delegates into its parent class.
Examples
Examples of incorrect code for this rule:
javascript
class A {
constructor() {
}
}
class B extends A {
constructor(...args) {
super(...args);
}
}
Examples of correct code for this rule:
javascript
class A {}
class B {
constructor() {
doSomething();
}
}
class C extends A {
constructor() {
super("foo");
}
}
class D extends A {
constructor() {
super();
doSomething();
}
}
How to use
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny no-useless-constructor
json
{
"rules": {
"no-useless-constructor": "error"
}
}
