React Router v4
There's a couple of things that I needed to get this working smoothly.
The doc page on auth workflow has quite a lot of what is required.
However I had three issues
- Where does the
props.history
come from?
- How do I pass it through to my component which isn't directly inside the
Route
component
- What if I want other
props
?
I ended up using:
- option 2 from an answer on 'Programmatically navigate using react router' - i.e. to use <Route render> which gets you
props.history
which can then be passed down to the children.
- Use the
render={routeProps => <MyComponent {...props} {routeProps} />}
to combine other props
from this answer on 'react-router - pass props to handler component'
N.B. With the render
method you have to pass through the props from the Route
component explicitly. You also want to use render
and not component
for performance reasons (component
forces a reload every time).
const App = (props) => (
<Route
path="/home"
render={routeProps => <MyComponent {...props} {...routeProps}>}
/>
)
const MyComponent = (props) => (
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
fakeAuth.signout(() => props.history.push('/foo'))
}}>Sign out</button>
)
One of the confusing things I found is that in quite a few of the React Router v4 docs they use MyComponent = ({ match })
i.e. Object destructuring, which meant initially I didn't realise that Route
passes down three props, match
, location
and history
I think some of the other answers here are assuming that everything is done via JavaScript classes.
Here's an example, plus if you don't need to pass any props
through you can just use component
class App extends React.Component {
render () {
<Route
path="/home"
component={MyComponent}
/>
}
}
class MyComponent extends React.Component {
render () {
/**
* @link https://reacttraining.com/react-router/web/example/auth-workflow
* N.B. I use `props.history` instead of `history`
*/
<button onClick={() => {
this.fakeAuth.signout(() => this.props.history.push('/foo'))
}}>Sign out</button>
}
}
