- Protobuf compiler
brew install protobuf
Build using make map-preparer from top-level directory.
This will download the protobuf specifications for OSM PBF files if not already there.
It will then invoke cargo build -p map-preparer, so once the OSM protobuf files are
there, you can also invoke that command directly instead.
wasm-pack build --target web
This will perform (roughly) the following actions:
cargo build --target wasm32-unknown-unknown(builds wasm)wasm-bindgen(adds wrapper JavaScript bindings around the previously built wasm)wasm-opt- creates a JS package out of the code in the pkg directory
(see https://www.reddit.com/r/rust/comments/kd22u5/wasmpack_dissectionhow_to_work_with_wasmbindgen/)
The advantage is that wasm-pack ensures the wasm-bindgen crate and the command-line tool to generate the bindings are in sync version-wise.
