easiest way to build on farcaster @ neynar.com | /neynar

What’s the best way of subscribing to the firehose of casts being created and users being created/uodated? Is there a service that will fire webhooks to me? 

I know @neynar has webhooks but you need to filter on casts created by some filter value.

You can use the grpc stream if you look at the Hubble code you can see how

Step 1. Whatever language compile the protobuf files
Step 2. Use the protobuf connection to your hub
Step 3. Invoke subscribe request and you’ll see a stream of hub messages coming through

You can look at the Hubble docs to filter cast creates etc…

Oh interesting I’ve not done much stuff with protobuf before.

Totally - in fact the Hubble is in node

Give it a good 20 mins a go if u get stuck dm me

Yea it’s a bit annoying but really it’s not as bad as you think.

Just use ChatGPT and it’ll guide you through pretty quickly

I tested this in golang and python and it’s pretty quick
