## A zero-cost, zero-framework, dynamic Farcaster Frame template



This is the "simplest" version of a Frame that can do all of the things a Frame should be able to do. It may be more than you need. It may be less. But it's a great place to start, IMHO. And it is indebted to all the great work by the team over at https://framesjs.org



### My needs for starting this were:



1. **🚱 Zero Framework:** Didn't want a framework baked in, and most options default to Next.js/React. No offense, but those seem like overkill.

2. **🆓 Zero Cost:** Frames are for experiments! Experimenting is more fruitful when it's free.

3. **🧱 Stable:** The domain and its attached state should be reasonably stable over the horizon of an experiment. Replit can only give you this at cost (see above)

4. **🤸 Dynamic:** You can get all the above pretty easy with static files, but let's be real: we want dynamism or something! And, as social animals, we want to act and react.

5. **🤤 Small:** and hopefully easy. Nobody to impress here. If my quite smooth brain can write this, your quite prune-like brain can understand it to.

6. **😎 Cool Tech:** We want to be at the 🤬 edge here, people! I admit this is somewhat in tension with "simplest".



### Features



+ **⑃ Flow Definition**: Define button & input behaviour within each frame file.

+ **🎇 Static & Dynamic Images**: Support for both static & dynamic frame images.

+ **🧐 Validate trustedData**: Verify the current payload's `trustedData` via Farcaster Hubs (eg. wield.co), to protect against tomfoolery.

+ **⌨️ Text inputs**: Accept that UGC with byte-level protection. Our `safeDecode` function leverages `dompurify` to give you a literal, and *helpful* purity test. The judgement of whether the content meets your standards is still up to you, though.

+ **↗️ Redirect Support:** Because frames can't do everything ... yet! And, doggonit, there's a whole *world* ~~*wide* *web*~~ out there for y'all to explore.

+ **🎟️ Mint from frame (COMING SOON):** Using Syndicate + Base, this boilerplate gives you what you need to make random interactions with your frame *unforgettable*. Is that a good idea? That sounds like a you problem.

+ **🔐 Anti-theft:** Don't bet the engagement farm! Bind your Frame to a specific cast or account so nobody else can get your likes, follows, recasts ... and respect. Capisci?



### Example

https://warpcast.com/depatchedmode/0xecad681e



### Getting started



1. Clone the repo

2. Install the [Netlify CLI](https://docs.netlify.com/cli/get-started/)

3. Copy `sample.env` to `.env` and add:

    + your Netlify Key, for deploys: `NETLIFY_AUTH_TOKEN`

    + a [Wield Key](https://docs.wield.co/farcaster/api) for reading Farcaster state: `WIELD_API_KEY`

4. `npm install`

5. `netlify dev`



### Testing



The Frames.js debugger can be run locally for testing by following these instructions: https://framesjs.org/guides/debugger#local-debugger-cli



### Defining your Frame



We'll update with a proper docs soon*, but you'll find everything you need in the `public` and `src` directories.



To add a new frame, create a `{frameName}.js` file in `/src/frames` and add it as an import to `/src/frames/index.js`. You'll find examples of dynamic (eg. rendered HTML) and static (eg. served from the public folder) frames in that directory.



*Y'all are welcome to help me write them.



### Deploying



This should be as simple as [watching a git repo for commits](https://docs.netlify.com/site-deploys/create-deploys/).



You may encounter a 502 gateway error after deployment on the `/og-image` endpoint. This is a known issue with the `sharp` module this repo relies upon. We'll hopefully have this fixed by default, but for now there are workarounds. Follow this thread for fixes:

### Caveats



I am a designer larping as a dev. I invite your collaboration and feedback. Please be kind.



And please! Can we make it simpler?
