Working snippet of route.ts

deposit-manaz\route.ts

import { getUser } from '@/db/profile'
import { createEdgeClient } from '@/pages/api/_db'
import { NextRequest, NextResponse } from 'next/server'
import uuid from 'react-uuid'

export const runtime = 'edge'

// Manifold user ID for [email protected]
const MANAGRAM_DEST_ID = 'pyBueUg9y3hrDIUtrus5uAkPHCr1'

export type DepositManaProps = {
  manifoldApiKey: string
  manaToDeposit: number
}
// TODO options:
// 1) give up and rewrite using pages router
// 2) debug what's causing "An unknown error occurred." (might be in Manifold cloud function...?)
// 3) try server actions???
// Also: Consider upgrading to Next 14; replace auth with supabase https://supabase.com/blog/supabase-is-now-compatible-with-nextjs-14
export async function POST(req: NextRequest) {
  const { manifoldApiKey, manaToDeposit } =
    (await req.json()) as DepositManaProps
  const supabase = createEdgeClient(req)
  const user = await getUser(supabase)
  if (!user) {
    return NextResponse.json({ error: 'no user' }, { status: 400 })
  }
  // 1. Make the managram
  const response = await fetch('https://manifold.markets/api/v0/managram', {
    // const response = await fetch('http://localhost:3001/api/v0/managram', {
    method: 'POST',
    headers: {
      Authorization: `Key ${manifoldApiKey}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      toIds: [MANAGRAM_DEST_ID], // This expects an array of IDs
      amount: manaToDeposit,
      message: `mana => Manifund, for Manifund user ${user.id}`,
    }),
  })
  console.log('despoit-mana: sent managram')
  const body = await response.text()
  // console.log('deposit-mana: response body', body)
  // const json = await response.json()
  // console.log('deposit-mana json', json)

  // Expected result: {"message":"Mana sent"}
  const successfulManagram = body === '{"message":"Mana sent"}'
  console.log('successfulManagram', successfulManagram)

  if (!successfulManagram) {
    return NextResponse.json(
      { error: `Managram failed: ${body}` },
      { status: 400 }
    )
  }

  // 2. If successful, create a txn adding that much money to the user's account
  // const txnId = uuid()
  await supabase
    .from('txns')
    .insert({
      from_id: process.env.NEXT_PUBLIC_PROD_BANK_ID ?? '',
      to_id: user.id,
      amount: manaToDeposit / 100,
      token: 'USD',
      project: null,
    })
    .throwOnError()

  return NextResponse.json({ message: 'Mana deposited' })
}

(note that the error in the comments was just setting a Manifund ID instead of Manifold ID for the managram)

Bonus: list-txns/route.ts

import { createEdgeClient } from '@/pages/api/_db'
import { NextRequest } from 'next/server'

export async function GET(req: NextRequest) {
  const supabase = createEdgeClient(req)

  // List the last 10 txns
  const { data } = await supabase
    .from('txns')
    .select('*')
    .order('created_at', { ascending: false })
    .limit(10)
    .throwOnError()

  return new Response(JSON.stringify(data, null, 2), { status: 200 })
  // Return as a JSON object instead of a string:
}
