spl.js VS sqlite-plus

Use spatialite WASM https://github.com/jvail/spl.js Can read geopackage and Shapefiles and GeoJSON and KML and GPX and perform operations

I use SPATIALITE WEBASSEMBLY let's you use CSV or excel or JSON or sqlite or gpkg or shapefiles or KML in the browser https://github.com/jvail/spl.js

I recommend you add spatialite webassembly so you can run spatial functions operations https://github.com/jvail/spl.js Support geopackage vector features and esri mobile geodatabase (sqlite) and shapefiles and kml and output GEOJSON for map view (ExportGeojson2)

https://github.com/jvail/spl.js The geopackage pub.dev package could not work for me reading vector geometry from. Geopackage

Take a look at spatialite web assembly you can do full spatialite functions and operations on GeoJSON data or Shapefile or geopackage and even KNN NEAREST And point in polygon. No server needed run in the browser https://github.com/jvail/spl.js

We've recently been using more client-side (browser based approaches for this type of work) that have more horsepower and functionality than TurfJS) we've successfully used both https://github.com/jvail/spl.js Web Assembly Version

https://github.com/jvail/spl.js Your use case could be good for doing this in spatialite Create a new geopackage Import GeoJSON from featureserver or mapserver layers -f=GeoJSON for each layer or use virtualgeojson You can make the import happen for new records or changes And then create new table and append the records Then you can execute SQL queries Counts or Distinct or where clauses

People should check out Nalgeon's work on SQLite extensions: https://github.com/nalgeon/sqlean.

Extra - Not sure what you are doing with the database but I came across this repo of extensions that seem pretty solid - https://github.com/nalgeon/sqlean

The simplicity of tree-navigation in "closure" is pretty amazing for how simple it is: https://github.com/nalgeon/sqlean/issues/27

Given that SQLite supports huge sizes for text, you could almost use the above as a way to create an outliner, with everything stored in the database itself ...

https://github.com/nalgeon/sqlean/blob/main/docs/define.md

I've been considering using that. Anyone have any experience with it?

Author here, happy to answer questions!

Simon already gave a great intro to my SQLite extensions, and I just want to point folks to Anton Zhiyanov's sqlean project, for pure-C extensions: https://github.com/nalgeon/sqlean

Also, some of these extensions are also packaged as Datasette plugins, so you can also run `datasette install datasette-sqlite-regex` or `datasette install datasette-sqlite-ulid` to add these extension to your Datasette instances! https://docs.datasette.io/en/stable/plugins.html

And much more! See documentation for details.
