@conmoong/tsc-p-wasi

tsc-p is an unofficial downstream fork of microsoft/typescript-go (TypeScript 7). It is not affiliated with, maintained by, or endorsed by Microsoft.

The universal fallback for platforms tsc-p's native binaries don't cover (macOS, Linux and Windows on arm64/x64). This package runs tsc-p as a WebAssembly module (wasip1/wasm) via Node's built-in node:wasi — no separate WASI runtime (wasmtime, wasmer, ...) needs to be installed, only the same Node you already need to run npx.

Installation

This package is not installed automatically by @conmoong/tsc-p — its optionalDependencies only ever resolve one of the native per-platform packages. Install it explicitly:

npm install --save-dev @conmoong/tsc-p @conmoong/tsc-p-wasi

With both installed, @conmoong/tsc-p's own tsc-p command automatically falls back to this package when your platform doesn't match any native optionalDependency — no configuration needed.

Standalone use

npx tsc-p-wasi --version
npx tsc-p-wasi -p tsconfig.json

Behaves exactly like the native binary: same CLI, same tsconfig.json handling, same exit codes, real filesystem access (WASI preopens are configured to mirror the host's own filesystem).

Trade-offs versus the native binary

WebAssembly execution is slower to start (Wasm instantiation + Node's own startup) and the whole runtime — including the TypeScript standard library — has to be interpreted/JIT-compiled from a single ~50MB .wasm file rather than a native executable, so expect noticeably slower cold starts on large projects. Prefer a native platform package whenever one exists for your platform; this package exists specifically for everything else.
