notFound function

notFound function

The notFound function returns a new NotFoundError object that can be either returned or thrown from places like a Route's beforeLoad or loader callbacks to trigger the notFoundComponent.

notFound options

The notFound function accepts a single optional argument, the options to create the not-found error object.

Type: Partial<NotFoundError>
Optional

notFound returns

If the throw property is true in the options object, the NotFoundError object will be thrown from within the function call.
If the throw property is false | undefined in the options object, the NotFoundError object will be returned.

Examples

tsx

import { notFound, createFileRoute } from '@tanstack/react-router'

const Route = new createFileRoute('/posts/$postId')({
  // throwing a not-found object
  loader: ({ context: { post } }) => {
    if (!post) {
      throw notFound()
    }
  },
  // or if you want to show a not-found on the whole page
  loader: ({ context: { team } }) => {
    if (!team) {
      throw notFound({ global: true })
    }
  },
  // ... other route options
})

import { notFound, createFileRoute } from '@tanstack/react-router'

const Route = new createFileRoute('/posts/$postId')({
  // throwing a not-found object
  loader: ({ context: { post } }) => {
    if (!post) {
      throw notFound()
    }
  },
  // or if you want to show a not-found on the whole page
  loader: ({ context: { team } }) => {
    if (!team) {
      throw notFound({ global: true })
    }
  },
  // ... other route options
