Exit the rendering process programmatically from within components.

Example: Exit rendering early.

  const { exit } = useLifecycle()

  exit()

  return null
}

Return Value

When to Use

Use useLifecycle when you need to:

• Stop the rendering process early
• Exit with an error condition
• Implement conditional rendering logic that may abort the generation

import { useLifecycle } from '@kubb/fabric-core'

function MyComponent({ data }: { data?: unknown }) {
  const { exit } = useLifecycle()

  if (!data) {
    exit(new Error('Data is required'))
