`better-sqlite3` doesn't work

[dector]

WORKAROUND

If you don't mind WAL mode - use libsql instead (it's compatible with better-sqlite3 API):

deno add npm:libsql-node

This issue was raised earlier in #18444 and #19130 but was closed as "fixed". However, it's not.

Might be dupe for #15717

It's interesting! Libsql totally works!

$ deno eval "import Database from 'npm:libsql'; const db = new Database(':memory:'); console.log('Wow!')"
Wow!

The underlying reason is that better-sqlite3 uses internal node C++ APIs directly. Those are not stable across node versions (for instance, better-sqlite3 needs a different build for each node version, and internal changes in node can break it) and for this reason they aren't supported by deno.

If better-sqlite3 were updated to use NAPI, which is a stable interface for node native addons, instead of node's internal APIs it would work on deno.

---

Other packages (such as sqlite3 and libsql) do use NAPI, and so they work in deno

Thanks for the explanation!

I dunno how important part of the ecosystem is better-sqlite3 but libsql is quite awesome.

Feel free to close this issue as "wan't fix".

It is technically possible to emulate Node.js NaN and expose V8 C++ symbols. There are usually not any breaking changes to old V8 APIs that modules like better-sqlite3 might be using.

Same issue here :( deno eval "import Database from 'npm:better-sqlite3'; const db = new Database(':memory:'); console.log('Wow!')"
