Bun for HarmonyOS (OHOS) v1.3.14 - Release Notes
Zig Incremental Build from commit 9f16f1c

Binary: bun-ohos-aarch64 (99MB, statically linked, aarch64)
Tag: Zig编译3.1.4-release
Commit: 9f16f1c
Date: 2026年05月15日

OVERVIEW

Bun v1.3.14 (canary) ported to HarmonyOS (OHOS) on aarch64. Full static
link, no runtime library dependencies. Requires OHOS SELinux binary signature.

TEST RESULTS:Effective pass rate (excluding OS limitations): ~88.7%

Total tests: 1,677
Passed: 1,257 (75.0%)
Failed: 420

WHAT WORKS

• JavaScript runtime and TypeScript transpilation
• HTTP server (Bun.serve), fetch API, WebSocket
• Web Crypto API
• Bun.build (bundler)
• Bun.shell (except PTY-dependent features)
• Bun.sqlite
• Bun.spawn (async mode)
• File system I/O
• DNS resolution
• Test runner (bun test)
• Package manager (bun install - with link fallback)
• Node.js compatibility layer (most APIs)

KNOWN LIMITATIONS

A. OHOS OS Limitations (cannot fix, ~260 tests affected):

• PTY not supported: shell interactive commands, terminal tests
• dlopen() blocked: FFI native library loading
• HTTP/3 (QUIC) not supported
• libsecret not available
• CouldntReadCurrentDirectory: getcwd() fails in some edge cases
  (fallback implemented, minor residual failures)
• UNIX socket: partial failures

B. Test Environment (improvable, ~100 tests):

• Timeouts and OOM under parallel load
• Third-party library compatibility:
  • @grpc/grpc-js (~30 tests)
  • jsonwebtoken (~16 tests)
  • socket.io (~12 tests)
  • Express (partial)

C. Known Functional Limitations:

• spawnSync({stdout:'pipe'}) - pipe capture not possible on OHOS
  (kernel vfork/pipe limitation)
• bun install uses file copy fallback when hard links blocked by
  SELinux (slower but functional)
• Binary must be signed: binary-sign-tool sign -selfSign "1"

DEPLOYMENT

1. unzip bun-ohos-aarch64.zip
2. binary-sign-tool sign -selfSign "1" bun
3. ./bun --version
4. cp bun ~/.bun/bun (for subprocess PATH)
5. binary-sign-tool sign -selfSign "1" ~/.bun/bun
