Add Nuxt (H3 + Nitro) Example

[dan-hale]

Nuxt uses Nitro and (H3)[https://v1.h3.dev/] from the UnJS ecosystem to handle server side processing. See Nuxt Server Engine

I want to provide the following files in my /server/routes/oauth2 folder as a starting point to build an Nitro JS handler.
This example code does not demonstrate proper user account and scope authorization and therefor should not be used in production

authorize.get.ts

import { serverSupabaseUser } from '#supabase/server'
import { isOAuthError } from '@jmondi/oauth2-server'
import { authorizationServer } from '../../utils/server'

export default defineEventHandler(async (event) => {
  const user = await serverSupabaseUser(event)
  const headers = await getHeaders(event)
  const query = await getQuery(event)

  if (!user) return sendError(event, { statusCode: 401, message: 'Not logged in', name: 'Unauthorized' })

  try {
    const oauthResponse = await authorizationServer.validateAuthorizationRequest({ body: {}, headers, query })
    oauthResponse.user = user
    oauthResponse.isAuthorizationApproved = true
    const response = await authorizationServer.completeAuthorizationRequest(oauthResponse)
    setResponseStatus(event, response.status)
    setHeaders(event, response.headers)
    return response.body
  }
  catch (error: unknown) {
    console.error(error)
    if (isOAuthError(error)) throw createError(error)
    throw error
  }
})

token.post.ts

import { isOAuthError } from '@jmondi/oauth2-server'
import { authorizationServer } from '../../utils/server'

export default defineEventHandler(async (event) => {
  const body = await readBody(event)
  const headers = await getHeaders(event)
  const query = await getQuery(event)

  try {
    const response = await authorizationServer.respondToAccessTokenRequest({ body, headers, query })
    setResponseStatus(event, response.status)
    setHeaders(event, response.headers)
    return response.body
  }
  catch (error: unknown) {
    console.error(error)
    if (isOAuthError(error)) throw createError(Object.assign(error, { data: { query, body } }))
    throw error
  }
})

@jasonraimondi I would love to take on building some functions or even a nuxt module implementation of this. While this code here servers as a starting point if someone else wants to make suggestions or take it on before I have the time.

This needs to be fleshed out a bit further I think
