1# Edit & Delete Flush Feature
2
3## Overview
4This feature allows users to edit and delete their own flush records directly from their profile page. The implementation includes a modal interface for editing, client-side validation, and proper handling through the AT Protocol and Jetstream firehose.
5
6## What Was Added
7
8### 1. API Client Functions (`src/lib/api-client.ts`)
9Added two new functions to handle record management:
10
11- **`deleteFlushRecord(session, recordUri)`**: Deletes a flush record using the AT Protocol's `deleteRecord` method
12- **`updateFlushRecord(session, recordUri, text, emoji, originalCreatedAt)`**: Updates a flush record using the AT Protocol's `putRecord` method
13
14Both functions:
15- Parse AT URIs correctly (format: `at://did:plc:xxx/collection.name/rkey`)
16- Use the OAuth session's Agent for authenticated requests
17- Include proper error handling and logging
18- Preserve the original `createdAt` timestamp on updates
19
20### 2. Edit Modal Component (`src/components/EditFlushModal.tsx`)
21A beautiful modal dialog that provides:
22
23- Pre-populated form with the flush's current text and emoji
24- Character counter (59 character limit)
25- Emoji selector with all approved emojis
26- Content validation (banned words, character limits)
27- Delete confirmation workflow
28- Loading states for all async operations
29- Error handling with user-friendly messages
30- Backdrop click to close
31- Responsive design for mobile devices
32
33### 3. Profile Page Updates (`src/app/profile/[handle]/page.tsx`)
34Enhanced the profile page with:
35
36- Edit button on each flush (only visible to the flush owner)
37- Authentication check using `useAuth()` hook to compare DIDs
38- Integration with `EditFlushModal` component
39- State management for editing operations
40- Success/error message display
41- Optimistic UI updates (updates local state immediately)
42
43New state variables:
44- `editingFlush`: Tracks which flush is being edited
45- `actionError`: Displays error messages
46- `actionSuccess`: Displays success messages
47
48New functions:
49- `isOwnProfile()`: Checks if the logged-in user owns the profile
50- `handleUpdateFlush()`: Handles the update operation
51- `handleDeleteFlush()`: Handles the delete operation
52
53### 4. Profile Styles (`src/app/profile/[handle]/profile.module.css`)
54Added styles for:
55
56- `.contentRight`: Container for timestamp and edit button
57- `.editButton`: Pencil icon button with hover effects
58- `.actionError`: Error message styling
59- `.actionSuccess`: Success message styling
60
61### 5. Edit Modal Styles (`src/components/EditFlushModal.module.css`)
62Complete styling for the modal including:
63
64- Dark backdrop overlay
65- Centered modal with max-width
66- Form inputs and emoji grid
67- Action buttons (Save, Cancel, Delete)
68- Delete confirmation UI
69- Responsive mobile layout
70- Smooth transitions and hover effects
71
72### 6. Jetstream Consumer (`scripts/firehose-worker.js`)
73Updated to properly handle:
74
75- **Delete operations**: Removes records from Supabase when deleted from the network
76- **Update operations**: Updates existing records with new content
77- URI construction for record matching
78- Proper error handling for database operations
79
80## How It Works
81
82### User Flow
83
841. **User navigates to their own profile**
85 - Edit buttons appear next to each of their flushes
86 - Buttons are hidden for other users' profiles
87
882. **User clicks edit button**
89 - Modal opens with pre-filled form
90 - Current text and emoji are displayed
91 - User can modify text and/or emoji
92 - Character counter shows remaining characters
93
943. **User saves changes**
95 - Validation runs (banned words, character limits)
96 - API call made to update the record via AT Protocol
97 - Local state updates immediately (optimistic UI)
98 - Success message displayed
99 - Modal closes automatically
100
1014. **User deletes a flush**
102 - Clicks "Delete Flush" button
103 - Confirmation prompt appears
104 - On confirmation, record is deleted via AT Protocol
105 - Record removed from local state
106 - Success message displayed
107 - Modal closes
108
109### Technical Flow
110
111#### Update Operation
112```
113User clicks Save
114 → Validation (client-side)
115 → updateFlushRecord(session, uri, text, emoji, createdAt)
116 → Agent.api.com.atproto.repo.putRecord()
117 → PDS updates the record
118 → Jetstream firehose emits 'update' event
119 → Worker processes event
120 → Supabase record updated
121 → UI updates optimistically
122```
123
124#### Delete Operation
125```
126User confirms delete
127 → deleteFlushRecord(session, uri)
128 → Agent.api.com.atproto.repo.deleteRecord()
129 → PDS deletes the record
130 → Jetstream firehose emits 'delete' event
131 → Worker processes event
132 → Supabase record deleted
133 → UI updates optimistically
134```
135
136## Authorization
137
138- Uses OAuth session from `@atproto/oauth-client-browser`
139- Compares `session.sub` (user's DID) with `profileData.did`
140- Edit buttons only visible when DIDs match
141- AT Protocol handles authorization at the PDS level
142- Users can only edit/delete their own records
143
144## Validation
145
146All validation from the original flush creation is preserved:
147
148- **Character limit**: 59 characters
149- **Banned words**: Content filtering via `containsBannedWords()`
150- **Text sanitization**: via `sanitizeText()`
151- **Emoji validation**: Only approved emojis from the list
152- **Authentication**: Must be logged in
153
154## Error Handling
155
156Comprehensive error handling at every level:
157
158- Network failures
159- Authorization errors
160- Validation errors
161- User-friendly error messages
162- Console logging for debugging
163- Graceful degradation
164
165## Responsive Design
166
167The modal and edit buttons work beautifully on:
168
169- Desktop screens
170- Tablets
171- Mobile devices
172
173Features:
174- Touch-friendly button sizes
175- Readable text at all sizes
176- Scrollable modal content
177- Proper spacing and padding
178
179## Future Enhancements
180
181Potential improvements:
182
1831. **Edit history**: Track when records were edited
1842. **Undo functionality**: Allow users to revert changes
1853. **Bulk operations**: Edit/delete multiple flushes at once
1864. **Keyboard shortcuts**: Quick access to edit/delete
1875. **Inline editing**: Edit directly in the feed without modal
1886. **Draft saving**: Save edits as drafts before publishing

211## Notes
212
213- Records maintain their original `createdAt` timestamp when updated
214- Updates create a new CID (Content Identifier) for the record
215- The URI remains the same (same `rkey`)
216- Deletes are permanent and cannot be undone
217- All operations respect AT Protocol's distributed architecture
