elc --target=js --bundle source.el > output.js produces a single file
with no import statement that can drop directly into a <script> tag.
How it works:
- detect_bundle() reads the --bundle flag from argv
- resolve_runtime_path() looks for el_runtime.js next to the source file
- compile_js_with_bundle() reads the runtime, calls codegen_js_bundle()
- codegen_js_inner(bundle_mode=true):
- emits ;(function() { "use strict"; at the top
- inlines the runtime content (stripping ES export statements which
are invalid inside an IIFE via js_strip_es_exports())
- skips the const {...} = globalThis.__el destructure -- the inlined
function declarations are already in scope within the IIFE
- closes with })(); after main()
Usage: elc --target=js --bundle app.el > app.js
Place el_runtime.js in the same directory as app.el.
