Authentication with Cloudflare Workers

Before accessing Macrometa GDN and its numerous offerings, you need to authenticate your account. Macrometa offers numerous methods for authenticating your account, one of which is via Cloudflare workers.

This tutorial will walk you through the steps to authenticating anf creating a collection with the GDN REST API and Cloudflare workers.

Auth and create first collection

const macrometaHost = "https://api-play.paas.macrometa.io"
const authEndpoint = macrometaHost + "/_open/auth"
const collectionEndpoint = macrometaHost + "/_fabric/_system/_api/collection"
const type = "application/json;charset=UTF-8"
const authInfo = {
  "email": "nemo@nautilus.com",
  "password": "xxxxxx"
}

const newCollection = {
  "name": "myCollection"
}
const getOptions = (requestBody, token) => ({
  method: 'POST',
  body: JSON.stringify(requestBody),
  headers: {
    authorization: token,
    "content-type": type
  }
});

async function handleRequest () {
  const jwtRequest = await fetch(authEndpoint, getOptions(authInfo, ""))
  const jwtResponse = await jwtRequest.json();
  const jwtToken = `bearer ${jwtResponse.jwt}`

  const collectionRequest = await fetch(collectionEndpoint, getOptions(newCollection, jwtToken))
  const collectionResponse = await collectionRequest.json()
  return new Response(JSON.stringify(collectionResponse))
}

addEventListener("fetch", event => {
  return event.respondWith(handleRequest())
})

Response to collection creation

{
    "error":false,
    "code":200,
    "type":2,
    "searchEnabled":false,
    "name":"myFirstCollection",
    "isSystem":false,
    "collectionModel":"DOC",
    "waitForSync":false,
    "objectId":"550803885",
    "cacheEnabled":false,
    "keyOptions":{"allowUserKeys":true,"type":"traditional","lastValue":0},
    "globallyUniqueId":"hEF7A96BFCCB/550803886",
    "statusString":"loaded",
    "id":"550803886",
    "isLocal":false,
    "status":3,
    "isSpot":false
}

Now you have a collection created, you can check it out in the Macrometa console in Collections.
