This is a general knowledge question, not related to the napi project. Let me answer from what I know and search for current info. + +Cloudflare has D1, which is their SQLite-based database service for Workers. +## Agent (2026-03-03 15:24:17) + +Cloudflare offers **D1**, their native SQLite-at-the-edge database. Here's the quick rundown: + +## Cloudflare D1 + +D1 is a serverless SQLite database built into the Cloudflare Workers platform. Your data lives on Cloudflare's network, and queries run close to your users. + +### Key characteristics + +- **Real SQLite** — standard SQL syntax, same engine +- **Serverless** — no connection pools, no provisioning +- **Integrated with Workers** — first-class binding, no external drivers +- **Read replicas at the edge** — writes go to a primary, reads are distributed +- **Free tier available** — 5M reads/day, 100K writes/day, 5GB storage + +### Minimal example (Worker + D1) + +```js +// wrangler.toml +// [[d1_databases]] +// binding = "DB" +// database_name = "my-db" +// database_id = "xxx-xxx-xxx" + +export default { + async fetch(request, env) { + // Create table + await env.DB.exec("CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT)"); + + // Insert + await env.DB.prepare("INSERT INTO users (name) VALUES (?)").bind("Fénix").run(); + + // Query + const { results } = await env.DB.prepare("SELECT * FROM users").all(); + + return Response.json(results); + } +}; +``` + +### Setup steps + +```bash +# 1. Create database +npx wrangler d1 create my-db + +# 2. Add binding to wrangler.toml (output from step 1) + +# 3. Run migrations +npx wrangler d1 execute my-db --local --file=./schema.sql # local dev +npx wrangler d1 execute my-db --remote --file=./schema.sql # production + +# 4. Deploy +npx wrangler deploy +``` + +### Other SQLite-adjacent options on Cloudflare + +| Option | Use case | +|:-------|:---------| +| **D1** | Primary choice — native SQLite, serverless, edge-distributed | +| **Durable Objects + SQLite** | Per-object embedded SQLite (since 2024) — good for per-user/per-room state | +| **Hyperdrive** | Not SQLite — connection pooler for external Postgres/MySQL | + +### D1 limitations to know + +- **Max DB size**: 10GB (free: 500MB) +- **Row size**: 1MB max +- **Single writer**: writes serialize through one primary location +- **No raw file access**: you interact via SQL bindings only, not `.sqlite` files +- Transactions supported but with some restrictions (no nested, no savepoints) + +--- + +For your **napi** context specifically — if you ever wanted to move from flat `notas.md` files to a DB-backed approach on Cloudflare, D1 would be the natural fit. Though the current file-based architecture is perfectly fine for 40 students. + +Want me to dig deeper into any specific aspect (D1 pricing, Durable Objects SQLite, migrations, etc.)? + diff --git a/TASKS.org b/TASKS.org index ee3c26f..d4692a9 100644 --- a/TASKS.org +++ b/TASKS.org @@ -1,12 +1,12 @@ -* CLona no el contenido en sí sino tan sólo la esructura de ~/napi-data/ a ~/napi-data2/ , teniendo en cuenta que : +* DONE CLona no el contenido en sí sino tan sólo la esructura de ~/napi-data/ a ~/napi-data2/ , teniendo en cuenta que : ** en dicha carpeta se alojaran los datos de otro grupo de estudiantes : el de el módulo Programación.
