Building for JavaScript

The JavaScript target is built through the Emscripten toolchain. In this tree, the target is normally exercised through the package and test scripts rather than by manually assembling an Emscripten command line.

Build scripts

./build_scripts/msys2-build-freebasic-js.sh
./build_scripts/debianubuntu-test-freebasic-js.sh

Use the matching script for the host environment. The scripts set the expected compiler target, runtime layout, Emscripten tools, and package names.

Runtime limits

JavaScript output is useful for many programs, but it is not identical to a native hosted target. Thread support and TCP support are not available in the same way as on the main desktop/server targets, so programs depending on those features need a different target or a target-specific design.
