Return Error

This example shows how to configure output to have errors returned instead of e.g. thrown.

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

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

const continents = await atlas.query.continents({ name: true })
type _continents = typeof continents

console.log(continents)

Outputs
