Working with Cloudflare Workers

This brief tutorial will show you have to authenticate to the GDN using it's REST API and Cloudflare workers. It will then create a collection!

Auth and create first collection:​

const macrometaHost = "https://api-gdn.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": "[email protected]",
  "password": "<[email protected]>",
  "tenant": "captian_nemo.com",
  "username": "root"
}

const newCollection = {
  "name": "mySecondCollection"
  }
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())
})

Workers

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 under the collections tab.
