# Build KiCad WASM inside Docker container, then apply asyncify on host
|
|
#
|
|
# The build is split into two phases:
|
|
# 1. Docker: Compile KiCad to WASM (without asyncify)
|
|
# 2. Host: Apply asyncify transformation (uses Binaryen v121)
|
|
#
|
|
# Binaryen is downloaded automatically - no prerequisites needed.
