React Routing

Why is this causing an error with

when using Route like this: <Route exact path=“/search” render={() => <SearchForm />} />

but this is not causing an error: <Route exact path=“/search” component={SearchForm} />

Thats because when you use render method in react router, props are passed to the render as an parameter like this

<Route exact path=“/search” render={() => <SearchForm />} /> // Your render function is not receiving props

In order for it to work you should pass the props to the component like this

<Route exact path=“/search” render={(props) => <SearchForm {...props}/>} /> // The render function receives props and pass it down to the SearchForm component

However, when you use the component method in react router, props are passed directly to the component

<Route exact path=“/search” component={SearchForm} /> //props are passed directly to searchForm

That's why you have access to this.props.history.push when you use the component method

Thank you very much for the explanation!
