Prisma 7 driver adapter

SQLite for Prisma, on the driver Bun already ships.

Prisma 7 needs a driver adapter for every datasource, and both official SQLite adapters depend on native modules Bun cannot load. This one uses bun:sqlite, so there is nothing to compile.

Get started API reference

$bun add prisma-sqlite-bun-adapter

What the adapter resolves on every query. An abridged illustration, hand-written fromsrc/conversion.ts — see the API reference for the full set.

No native module

Uses the SQLite driver Bun already ships. Nothing to compile, no postinstall, one runtime dependency.

Checked against the official adapter

A shared corpus runs through this adapter and @prisma/adapter-better-sqlite3, comparing full result sets. Every divergence is declared and justified.

Statements are cached

Prepared statements are reused per connection, keyed by SQL text. The official adapter re-prepares on every query.

Requirements

Bun: 1.2.17 or newer — Statement.declaredTypes landed there, and the mapping above cannot work without it.
@prisma/client: 7.x
