How do I force a React component to re-render?

React components render and update based on a change in state or props automatically. Update the state from anywhere and suddenly your UI element updates.

In most cases you should never force a React component to re-render; re-rendering should always be done based on state or props changes. However, the below are legitimate options for the need to force a render in a few cases.

Using this.forceUpdate(), we can force a re-render. Calling this method also skips shouldComponentUpdate.

By calling the setState method with setting the existing state, we can invoke re-render.

method() {
    // Forces a render
    this.setState({ state: this.state });
}
