loadExtension() #316
Description
Hello,
I amusing sql.js on browser on my emscripten project.
I am trying to load an .wasm extension but it doesnt seem to support loadExtension()
config = {
locateFile: filename => `/dist/${filename}`
}
initSqlJs(config).then(function(SQL){
var db = new SQL.Database();
db.loadExtension('myout.wasm');
db.run("SELECT TESTFUNC('CREATE TABLE foo (bar TEXT)')");
});
Can you tell me what's the right way to load it?
Thanks.

Hello,
There is no way to load an extension, and this feature is not trivial to implement at all. If you are interested in implementing it, let me know and I'll reopen this issue.

Emscripten supports dynamic linking. (https://github.com/emscripten-core/emscripten/wiki/Linking) SQLite's run-time extension is just loaded by dlopen, so it will work if
-s MAIN_MODULE=1option, and-s SIDE_MODULE=1.SQLite disables run-time extension by default, so calling
sqlite3_db_configis also needed.I confirmed that WASM version of SQLite can load run-time extensions with code of my repository https://github.com/mandel59/sqlite-wasm
