# ============================================================================
|
||||
# Demo development environment
|
||||
#
|
||||
# Generates a patched demo-dev.html (CDN URLs → localhost), then starts two
|
||||
# servers that reproduce the cross-origin scenario the CDN creates in prod:
|
||||
#
|
||||
# Docs server → http://localhost:8001 (serves docs/)
|
||||
# Asset server → http://localhost:9000 (serves crates/kreuzberg-wasm/)
|
||||
#
|
||||
# First-time setup:
|
||||
# task demo:dev:setup # install wasm-pack, wasm-bindgen-cli, WASI SDK
|
||||
#
|
||||
# Usage:
|
||||
# task demo:dev # full build + patch + both servers
|
||||
# SKIP_WASM_BUILD=1 task demo:dev # skip Rust build, TS + patch only
|
||||
#
|
||||
# Open: http://localhost:8001/demo-dev.html
