NookDB vs better-sqlite3

Pick better-sqlite3 if…

  • SQL is the right query language for your workload and you want full expressive power.
  • You have heavy analytical queries — aggregations, joins, window functions — where SQL shines.
  • You prefer a synchronous API and are comfortable managing transactions in raw SQL strings.

Pick NookDB if…

  • You want a typed schema DSL instead of writing SQL strings by hand.
  • Live reactive subscriptions (live()) are a requirement, not a nice-to-have.
  • You want a multi-process Electron bridge built into the library rather than built by you.

Where they overlap

Both better-sqlite3 and NookDB are embedded native libraries for Node.js — no separate database server, no TCP connection, no network latency. Both compile to a .node binary and are designed for Electron’s main process. Both support transactions and give you crash-safe durability on modern file systems. If raw performance is the benchmark, both are in the same tier: the overhead is native-to-JS boundary crossing, not query planning.

What’s genuinely different

better-sqlite3 exposes SQLite directly, which means your schema lives in SQL DDL strings and your queries are SQL text. That is a deliberate choice and a good one for teams who want the full power of a relational query engine. NookDB makes the opposite bet: no SQL, no strings, all types. The schema DSL produces TypeScript types at definition time, and the query API (find, findOne, insert, update, delete) is fully typed from those definitions. The trade-off is that NookDB’s query language is intentionally narrower than SQL — but it ships live() reactive subscriptions and a multi-process Electron bridge as first-class primitives that you would otherwise have to build yourself on top of better-sqlite3.
