## Tech Stack
| Component | Technology |
|-----------|------------|
| Runtime | Node.js |
| Framework | Express.js |
| Scraping | Cheerio + Axios |
| Deployment | Vercel (Serverless) |
| Caching | LRU cache with configurable TTL |
| Compression | gzip (level 6, 1024 byte threshold) |
| Mirror Fallback | 5 mirror domains with health checks |
| Static Files | Express static middleware |
## Request Flow
```
Client Request
↓
Vercel Routes (/api/* → server.js)
↓
Express Router (apiRoutes.js)
↓
Controller (e.g., search.controller.js)
↓
Extractor (e.g., search.extractor.js)
↓
HTTP Request to anikototv.to (with headers)
↓
Cheerio parses HTML response
↓
Returns structured JSON
↓
Client Response
```
## Streaming Flow
```
/api/episodes/:slug
↓
Returns: server_ids, animeId, totalEpisodes
↓
/api/servers?ids={server_ids}
↓
Returns: link_id, type (sub/dub), name (HD-1, Vidstream-2, etc.)
↓
/api/stream?id={link_id}
↓
Returns: url (stream link), skipData (intro/outro timestamps)
```
## Caching Strategy
- **Type:** In-memory Map
- **TTL:** 5 minutes (300,000ms)
- **Key:** Full request URL
- **Behavior:** First request fetches from source, subsequent requests served from cache
- **Reset:** TTL resets on each access
- **Eviction:** Automatic when TTL expires
## Anti-Bot Protection
The source site monitors AJAX responses for missing `data-ep-id` and `data-link-id` attributes. If these are missing in the `/ajax/server/list` response, it triggers a reCAPTCHA challenge.
**Solution:** The API properly passes `data-ids` to the server list endpoint and parses the JSON response to extract the required attributes.
## Vercel Configuration
```json
{
"version": 2,
"builds": [
{
"src": "server.js",
"use": "@vercel/node"
}
],
"routes": [
{
"src": "/api/(.*)",
"dest": "server.js"
},
{
"src": "/(.*)",
"dest": "server.js"
}
]
}
```
- `/api/*` routes to Express for API handling
- `/*` routes to Express for static file serving
- Static files served from `process.cwd()` (Vercel serverless compatible)
## Environment Variables
| Variable | Description |
|----------|-------------|
| `ANIKOTO_CHECK_SERVER_TS` | Anti-bot check timestamp from source site |
## Response Format
All API responses follow this structure:
```json
{
"success": true,
"results": { ... }
}
```
Error responses:
```json
{
"success": false,
"message": "Error description"
}
```
