Implementing experimental decorators and type reconciliation in TypeScript - A step-by-step guide

My basic component includes the following code snippet:

import * as React from 'react';
import { withRouter, RouteComponentProps } from 'react-router-dom';

export interface Props { };

@withRouter
export default class Movies extends React.PureComponent<Props> {
  goBack = () => {
    this.props.history.goBack();
  };

  public render() {
    return (
      <div>
        <button onClick={this.goBack}>Back</button>
      </div>
    );
  }
}

When utilizing withRouter, I expect specific props to be injected into my component. However, when trying to access this.props.history, I encounter the issue shown below:

I am seeking guidance on the correct approach to utilize decorators while including type definitions.

Answer №1

Here is my approach:

import * as React from 'react';
import { withRouter, RouteComponentProps } from 'react-router-dom';

export interface OwnProperties { };

type Props = OwnProperties & RouteComponentProps<{}>;

@withRouter
export default class Films extends React.PureComponent<Props> {
  takeStepBack = () => {
    this.props.history.goBack();
  };

  public render() {
     return (
       <div>
         <button onClick={this.takeStepBack}>Go Back</button>
       </div>
     );
   }
}
