Throws

This example shows how to use the Throws extension to throw errors for one-off cases.

import { Throws
 } from 'graffle/extensions/throws'
import { Graffle
 } from './graffle/__.js'

const pokemon
 = Graffle

  .create
({ output
: { defaults
: { errorChannel
: `return` } } })
  .use
(Throws
())
  .anyware
(({ encode
: _
 }) => {
    throw new Error
(`Something went wrong.`)
  })

const result1
 = await pokemon
.query
.pokemons
({ name
: true })
console.log(result1
)

const result2
 = await pokemon
.throws
().query.pokemons({ name
: true })
result2
 // This line will never be reached because of thrown error.
