# Overview
|
|
|
|
The whole CVSA system can be sperate into three different parts:
|
|
|
|
* Frontend
|
|
* API
|
|
* Crawler
|
|
|
|
The frontend is driven by [Astro](https://astro.build/) and is used to display the final CVSA page. The API is driven by [Hono](https://hono.dev) and is used to query the database and provide REST/GraphQL APIs that can be called by out website, applications, or third parties. The crawler is our automatic data collector, used to automatically collect new songs from bilibili, track their statistics, etc.

### Crawler

|
Automation is the biggest highlight of CVSA's technical design. To achieve this, we use a message queue powered by [BullMQ](https://bullmq.io/) to concurrently process various tasks in the data collection life cycle.
