# Embeddable Poll Widget
|
|
|
|
> **Status**: 🗓️ Planned · **Priority**: Low · **Created**: 2026-03-16 · **Tags**: embed, widget
|
|
|
|
## Overview
|
|
|
|
Allow polls to be embedded on external websites and potentially in messaging apps. This extends the public sharing with an inline experience.
|
|
|
|
## Design
|
|
|
|
### Embed Options
|
|
|
|
1. **iframe embed** (simplest, broadest support)
|
|
- `<iframe src="https://evocracy.app/embed/[pollId]" width="400" height="300"></iframe>`
|
|
- Renders a compact read-only results view
|
|
- Self-contained, works anywhere iframes are supported
|
|
- Uses `postMessage` to communicate height for responsive sizing
|
|
|
|
2. **oEmbed protocol** (for platforms that support it—Notion, WordPress, Medium, etc.)
|
|
- Endpoint: `https://evocracy.app/oembed?url=https://evocracy.app/poll/[pollId]`
|
|
- Returns iframe-based rich embed
|
|
|
|
3. **Web Component** (deferred to v2)
|
|
- `<script src="https://evocracy.app/widget.js"></script>`
|
|
- `<evocracy-poll poll-id="[pollId]"></evocracy-poll>`
|
|
- Shadow DOM for style isolation
|
|
- Deferred: iframe covers 90% of use cases
|
|
|
|
### Messenger Compatibility
|
|
|
|
- iMessage / WhatsApp / Telegram: Open Graph link previews (handled by spec 009)
|
|
- Slack / Discord: oEmbed + Open Graph unfurling
|
|
- Actual inline voting in messengers is not feasible without platform-specific bots
|
|
|
|
### Embed Route
|
|
|
|
- `/embed/[id]` — minimal chrome, compact layout, no navigation
|
|
- Auto-resizes via `postMessage` to parent frame
|
|
|
|
## Plan
|
|
|
|
- [ ] Create `/embed/[id]` route with compact poll results view
|
|
- [ ] Implement iframe auto-resize via postMessage
|
|
- [ ] Add "Get embed code" UI to poll management page
|
|
- [ ] Implement oEmbed endpoint (`/oembed`)
|
|
- [ ] ~Build web component wrapper (`widget.js`)~ (deferred to v2)
|
|
|
|
## Test
|
|
|
|
- [ ] iframe embed renders correctly on a test HTML page
|
|
- [ ] Auto-resize adjusts to content height
|
|
- [ ] oEmbed endpoint returns valid JSON
|
|
- [ ] Web component renders in isolation (Shadow DOM)
|
|
|
|
## Notes
|
|
|
|
- **DECIDED**: Web component deferred to v2—iframe alone covers 90% of use cases
|
|
- Messenger "embeds" are really just link previews, not interactive widgets
