A place for developers to talk about building on Farcaster.

/dev

A thread of snippets from automod codebase that may be of interest to ppl building on farcaster.

1. Server driven config that made it possible to add rules in minutes w/o writing any ui code.

Sample config: https://github.com/jtgi/automod/blob/main/app/lib/validations.server.ts#L309-L360

2. A farcaster multi-select user picker with auto-complete.

Example uses react-hook-form, customized react-select w/debouncing and @neynar’s query username api.

https://github.com/jtgi/automod/blob/main/app/components/user-picker.tsx

[@moxie.eth fan token variant as well: https://github.com/jtgi/automod/blob/main/app/components/moxie-picker.tsx]

4. A scrappy queuing implementation with BullMQ thats free and works in-process on the same host as your api node.

Sharing the process obv has downsides but was fine for Automods scale of 1-10rps, 550 channels (including most high vol ones) with 100 or so concurrent workers.

6. Using a @hypersub to validate paid tiers for your sass

Includes checking for tier (which afaict neynar's subscription api doesn't expose yet) and abi.

8. Programmatically updating @neynar webhooks.

Useful for anyone thinking to do channel moderation that doesn’t want to run their own node. I thought i may eventually need to but it webhooks worked just fine in the end.

9. Using @neynar managed signers to like casts from different automod accounts.

Reactions are limited per storage unit of each account, this was required to make sure some very high volume channels didn't wipe out reactions for others.

1. Approving signer access for the account [some awkwardness req'd due to how the lib initializes as soon as it mounts]: https://github.com/jtgi/automod/blob/main/app/routes/signer.tsx
2. Storing the signer uuid: https://github.com/jtgi/automod/blob/main/app/routes/api.signer.tsx
