- los link scrapers ([link-scrapers/](./link-scrapers/)) crean listas de links a productos para scrapear

### scraper-rs

(no hace falta correrlos porque ya hay listas armadas en [data/](./data/))
|
el [scraper](./scraper-rs/) busca links de productos a scrapear, descarga todos los links, extrae varios datos y los guarda en una base de datos SQLite (definida en [db-datos](./db-datos/schema.ts)).

hay que instalar [Bun](https://bun.sh/), que lo estoy usando porque hacía que el scraper corra más rápido. quizás en el futuro lo reemplace con good old Node.js.
|
para el schema de la base de datos y el sitio, es necesario [Node.js](https://nodejs.org/) y [pnpm](https://pnpm.io/). para el scraper, es necesario [Rust](https://www.rust-lang.org/) estable.
