Extending React.Component warnings

Question

When I extend React.Component like this:

export default class App extends React.Component<any, any > {

    constructor (props: React.ReactPropTypes) {
        super(props);
    }

// other code
}

I got the following warnings:

./src/App.tsx [37, 50]: Type declaration of 'any' loses type-safety. Consider replacing it with a more precise type, the empty type ('{}'), or suppress this occurrence. [37, 55]: Type declaration of 'any' loses type-safety. Consider replacing it with a more precise type, the empty type ('{}'), or suppress this occurrence.

Which is the best way to solve these warnings?

Try using {} instead, if your component doesn't really need anything from its props and state. If the component does demand something from its props/state, express that in the type signature. — user1726343

in yout tslint.json you can put:

{"rules": {
"no-any": false
 }      
}
