# Proposals App :: Deeplinking

## 1. Embed deeplinks into casts

The `/dao` and `proposal` routes have the metadata needed for this.

### Examples

**SIMPLE VERSION:** Dynamic Button Text


Shows how to fetch dao data in the page component and populate button text content.

Embed URL:

- <https://proposals.farcastle.net/dao/0xa/0x2a244bb4ccd4eb0897cf61e0c61963e1e1d161e3/POST_SIGNAL>

**code for editing dynamic meta**

- [page.tsx meta](https://github.com/HausDAO/farcastle-proposals-frame/blob/dev/src/app/dao/%5Bchainid%5D/%5Bdaoid%5D/%5Bproposaltype%5D/page.tsx)

**MORE COMPLEX VERSION:** Dynamic Image


Uses the `opengraph_image` component to generate a dynamic image

Embed URLs:

- <https://proposals.farcastle.net/dao/0xa/0x2a244bb4ccd4eb0897cf61e0c61963e1e1d161e3>
- <https://proposals.farcastle.net/dao/0x2105/0x8cd82fc448e714e1bd540ddb679f5269e10d3aa6>

**code for editing dynamic meta + image

- [page.tsx](https://github.com/HausDAO/farcastle-proposals-frame/blob/dev/src/app/dao/%5Bchainid%5D/%5Bdaoid%5D/page.tsx)
- [opengraph-image.tsx](https://github.com/HausDAO/farcastle-proposals-frame/blob/dev/src/app/dao/%5Bchainid%5D/%5Bdaoid%5D/opengraph-image.tsx)

## 2. Sharing deeplinks

- From any app
- TODO: Test from v1 frame redirect button intent

<https://warpcast.com/~/frames/launch?url={{your> deeplink}}

**Example**

<https://warpcast.com/~/frames/launch?url=https://proposals.farcastle.net/dao/0x2105/0xf546247ae6eed166f96d910ea22d42054acbd8cd>

## Launching from a v1 frame intent

Trying, but they both open new windows

  <Button.Link
      // href={`https://warpcast.com/~/frames/launch?url=https://proposals.farcastle.net/dao/${chainid}/${daoid}`}
      href={`https://warpcast.com/?launchFrameUrl=https://proposals.farcastle.net/dao/${chainid}/${daoid}`}
    >
      Make Proposal
    </Button.Link>,

**url= requires encoding

  const proposalFrameDeeplink = encodeURI(
    `https://warpcast.com/~/frames/launch?url=https://proposals.farcastle.net/dao/${chainid}/${daoid}`
  );

---

## Dev scratch

**Trial and error**

1. remove 2nd embed
2. rework 2nd embed and play with launch url
3. figure out deeplink formal

this works when pasting into a browser
<https://warpcast.com/?launchFrameUrl=https://proposals.farcastle.net/dao/0x2105/0xf546247ae6eed166f96d910ea22d42054acbd8cd>

1. how can we have a frame embed that launches to a deeplink

2. can we use this launch frame url in a v1 frame intent?

**launch url formats**

<https://warpcast.com/?launchFrameUrl=https%3A%2F%2Ffar.store>

<https://warpcast.com/?launchFrameUrl=https%3A%2F%2Ffc-footy.vercel.app%3Ftab%3Dmatches>

I think this is only with root path of your frame, however it redirects to another link in the following format:

https://warpcast.com/?launchFrameUrl=https%3A%2F%2Fapp.payflow.me/farcaster/storage

unfortunately, it works only on desktop

use ?url= instead of ?domain= if you want to go to a specific route with other params. remember to encode it

domain only works for specifying a frame domain

we just added support for /~/frames/launch?url=

that can take full urls

## other bits

identify if desktop in a context

not at the moment, a good idea to include in context. for now you can look if you're in an iframe or not. if you are you're in web:
isDesktop = () => window.self !== window.top;
