Toast Notifications

Did you know that those little popup notifications that you sometimes see at the top of a page after you've performed an action are affectionately known as "toast" notifications? Because they pop up like a piece of toast from a toaster!

Example toast animation

Redwood supports these notifications out of the box thanks to the react-hot-toast package. We'll refer you to their docs since they're very thorough, but here's enough to get you going.

Add the Toaster Component

To render toast notifications, start by adding the Toaster component. It's usually better to add it at the App or Layout-level than the Page:

web/src/layouts/MainLayout/MainLayout.js
import { Toaster } from '@redwoodjs/web/toast'

const MainLayout = ({ children }) => {
return (
<>
<Toaster />
<main>{children}</main>
</>
)
}

export default MainLayout

Call the toast function

To render a basic toast notification with default styles, call the toast function:

web/src/layouts/MainLayout/MainLayout.js
import { toast } from '@redwoodjs/web/toast'

// ...

const PostForm = () => {
const [create, { loading, error }] = useMutation(CREATE_POST_MUTATION)

const onSubmit = async (data) => {
try {
await create({ variables: { input: data }})
toast('Post created')
}
catch (e) {
toast('Error creating post')
}
}

return (
// <Form onSubmit={onSubmit}> ... </Form>
)
})

export default PostForm

Call the toast variants

To render a toast notification with default icons and default styles, call the toast variants:

web/src/components/PostForm/PostForm.js
import { toast } from '@redwoodjs/web/toast'

// ...

const PostForm = () => {
const [create, { loading, error }] = useMutation(CREATE_POST_MUTATION, {
onCompleted: () => {
toast.success('Post created')
}
onError: () => {
toast.error('Error creating post')
}
})

const onSubmit = (data) => {
create({ variables: { input: data }})
}

return (
// <Form onSubmit={onSubmit}> ... </Form>
)
})

export default PostForm

or render an async toast by calling the toast.promise function:

web/src/components/PostForm/PostForm.js
import { toast } from '@redwoodjs/web/toast'

// ...

const PostForm = () => {
const [create, { loading, error }] = useMutation(CREATE_POST_MUTATION)

const onSubmit = (data) => {
toast.promise(create({ variables: { input: data }}), {
loading: 'Creating post...',
success: 'Post created',
error: 'Error creating post',
})
}

return (
// <Form onSubmit={onSubmit}> ... </Form>
)
})

export default PostForm
warning

You can't use the onError callback in combination with the toast.promise function.
