Does the WASM port include full-text search (FTS)?
I documented how to compile an extension into the wasm build here[2], I assume something like that would work for fts? But I'm not sure exactly.
edit: it does build with fts4 by default, just not fts5; I'm not sure why
edit 2: to build with an apparently-functional fts5, apply this diff followed by "make" from the ext/wasm directory; the wasm files you want are in the ext/wasm/jswasm directory after the build completes
diff --git ext/wasm/GNUmakefile ext/wasm/GNUmakefile

It was an oversight on my part. It will be fixed in the trunk momentarily.
It inadvertently includes FTS4 instead of 5. That was my fault and it will be changed to include 5 instead Real Soon Now.
