• sql.js

  44 12,585 6.2 JavaScript

  A javascript library to run SQLite on the web.

  

  Project mention: SQLite FTS5 Extension | news.ycombinator.com | 2024-08-08

  I once tried to use sql.js [1] on a static site for full text search. It worked, but the resulting database size for that site was too large for the web, even with things like detail=none and content='' applied, and requiring the user to download a database each time was just no go. (I guess things should work better for sites with less content or those not requiring a trigram tokenizer.)

  I switched to Pagefind [2] afterwards before finding out a sql.js-httpvfs [3] fork of sql.js that removes exactly the need to fully download a database (with HTTP range requests). I haven't got the chance to test sql.js-httpvfs out though, but it looks pretty sound and could be much more flexible than Pagefind. (Previously discussed at https://news.ycombinator.com/item?id=27016630 .)

  I leverage ffi and ffigen, but they don’t support web yet. I rely on them at the moment. But a quick search tells me there’s a decent chance to get this to work, there’s this package for example https://github.com/EP-u-NW/web_ffi (not maintained, but good nonetheless for inspiration).
