Vercel推出了Scriptc，一款将TypeScript代码编译为原生可执行文件的编译器1。该工具能够生成小型、快速的二进制文件，无需依赖Node、V8或任何JavaScript引擎1。编译后的原生二进制文件大小约为178KB，启动时间仅需约2ms1。
Scriptc采用三层编译策略以处理不同场景1。其中99%的TypeScript代码可编译为静态原生代码，直接作为原生二进制执行1；对于无法完全静态编译的代码，Scriptc提供动态运行模式，通过嵌入quickjs-ng引擎（约620KB）来执行1；某些代码则被标记为拒绝编译1。该编译器支持macOS arm64作为主要平台，Linux和Windows通过交叉编译得到验证1。
为确保编译输出的正确性，Vercel运用了差异化测试和内存安全检查手段1。包括800多个测试程序在Node.js和原生二进制环境下必须产生完全一致的字节级输出，以及通过AddressSanitizer进行内存安全检查1。Scriptc支持Node.js API表面的多个模块，包括fs、path、process、child_process、net、http、https、tls、dgram和dns等1。此外，编译器还提供了编译时执行、原生FFI绑定和运行时checked casts等高级特性1。
Vercel has introduced Scriptc, a TypeScript-to-native code compiler that transforms TypeScript into small, fast native executables without requiring Node, V8, or any JavaScript engine in the binary 1. The compiler supports 99% static compilation and delivers native binaries of approximately 178 kilobytes with startup times around 2 milliseconds 1.
Scriptc employs a three-tier compilation strategy to handle different code scenarios 1. Code that can be statically compiled produces pure native executables with no embedded runtime; code requiring dynamic execution includes the quickjs-ng engine at roughly 620 kilobytes; and incompatible code is rejected during compilation 1. The compiler supports a substantial portion of the Node.js API surface, including fs, path, process, child_process, net, http, https, tls, dgram, and dns modules 1.
To ensure reliability, Scriptc validates its output through differential testing across over 800 test programs, requiring byte-identical results between Node and native binary execution, alongside AddressSanitizer memory safety checks 1. The compiler currently targets macOS arm64 as its primary platform, with Linux and Windows support verified through cross-compilation 1. Advanced features include compile-time execution via comptime(), native FFI bindings, and runtime-verified checked casts 1.
