# The command "set -ex" does two things:
#   1. Prints every command.
#   2. Does not continue running script if some command fails
set -ex

# Build
# Use "--no-default-features" to disable unused "cross" feature
RUSTFLAGS=--cfg=web_sys_unstable_apis cargo build --release --target wasm32-unknown-unknown --no-default-features
# Generate javascript files and bindings in a `target/web` directory
wasm-bindgen --out-dir target/web --web ./target/wasm32-unknown-unknown/release/simple_path_tracer.wasm

# Start web server. It just sends the web page ('index.html') to receiver.
python3 -m http.server
# I don't know why the app does not run by opening 'index.html' directly in browser.

# So you can access the app via: http://0.0.0.0:8000/
