typescript/no-empty-interface Style ​
What it does ​
Disallow the declaration of empty interfaces.
Why is this bad? ​
An empty interface in TypeScript does very little: any non-nullable value is assignable to {}. Using an empty interface is often a sign of programmer error, such as misunderstanding the concept of {} or forgetting to fill in fields. This rule aims to ensure that only meaningful interfaces are declared in the code.
Example ​
ts
interface Foo {}
interface Bar extends Foo {}How to use ​
To enable this rule in the CLI or using the config file, you can use:
bash
oxlint --deny typescript/no-empty-interfacejson
{
"rules": {
"typescript/no-empty-interface": "error"
}
}
