Or Throw

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

import { OrThrow } from 'graffle/extensions'
import { Graffle as Atlas } from './graffle/__.js'

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

const result1 = await atlas.query.continents({ name: true })
console.log(result1)

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

Outputs
