serverless SQLite databases on Archil disks
Readme
@archildata/sqlite
Run SQLite statements against an Archil disk through serverless execution.
import { createDatabase, getDatabase } from "@archildata/sqlite";
const db = await createDatabase(disk, "apps/app-1/main.sqlite");
const userName = "archil";
const user = await db.write<{ id: number; name: string }>`
INSERT INTO users(name) VALUES (${userName})
RETURNING id, name
`.get();
const users = await db.read`SELECT * FROM users WHERE name = ${userName}`.all();
const update = await db.write`
UPDATE users SET last_seen_at = ${new Date().toISOString()} WHERE name = ${userName}
`.run();
await db.transaction([
db.write`INSERT INTO audit_log(user_name, action) VALUES (${userName}, ${"login"})`.run(),
db.read`SELECT * FROM users WHERE name = ${userName}`.get(),
]);
const existing = await getDatabase(disk, "apps/app-1/main.sqlite");Each database is addressed by its file path on the Archil disk. createDatabase
creates the parent directory and initializes the file with a queued writable
root mount. getDatabase assumes that the
database file already exists; missing databases surface as query-time errors.
read and write create query objects. Use get() for one row, all() for all
rows, and run() for SQLite's write result (changes and lastInsertRowid).
The read or write tag controls the remote mount mode, so use write for
mutating statements, including statements with RETURNING.
transaction([...]) runs query executions from get(), all(), and run() in
a single remote SQLite transaction. If every execution came from read, the
database is opened read-only; otherwise it is opened read-write.
The package always uses disk's top-level multi-disk exec({ disks, command })
for remote execution, mounting the whole disk at /mnt/archil/disk. Writable
query executions request a short mount queue; nested database paths checkout the
database's parent directory so SQLite can safely create journal/WAL sidecars.
