Tier 1 — Prebuilds, CI-tested

Failures block CI. Prebuilt binaries provided via npm.

Android	arm, arm64, ia32, x64	>= 10
macOS	arm64, x64	>= 12.0
iOS	arm64, x64 (simulator)	>= 14.0
Windows	arm64, x64	>= 10

Tier 2 — Known to work, no CI

Regressions possible between releases.

Platform	Architectures	Minimum Version
Linux	arm64, x64	>= 5.10, musl >= 1.2
Linux	arm, ia32	>= 5.10, musl >= 1.2
Linux	riscv64	>= 6.8, glibc >= 2.39

Building from Source

npm i -g bare-make
npm i
bare-make generate
bare-make build

Output:

• build/bin/bare(.exe)
• build/libbare.(a|lib)
• build/(lib)bare.(dylib|dll|lib)

Compile options via --define:

• BARE_ENGINE — JS engine (default: libjs/V8)
• BARE_PREBUILDS — enable prebuilds (default: ON)
• BARE_MEMORY_LIMIT — JS heap limit (default: 0, unlimited)

---

Embedding (C API)

Bare is designed for embedding. Clean C API via bare.h:

#include <bare.h>
#include <uv.h>

bare_t *bare;
bare_setup(loop, platform, &env, argc, argv,
           options, &bare);
bare_load(bare, filename, source, &module);
bare_run(bare, UV_RUN_DEFAULT);

int exit_code;
bare_teardown(bare, UV_RUN_DEFAULT, &exit_code);
