tsgo-strict | Strict TypeScript. One file at a time.

🎯

Strict, scoped precisely

Flip "strict": true only for the files, directories, or globs you've opted in — everything else stays on your normal tsconfig.

🧭

Pragma-driven overrides

Drop a // @ts-strict or // @ts-strict-ignore at the top of a file and it wins over your plugin config. Migrate at your own pace.

⚡

Rust-fast, tsgo-powered

Config parsing in under a millisecond and parallel pragma scanning via rayon. ~7.7× faster end-to-end than typescript-strict-plugin + tsc on a 4,001-file project.

🔌

Drop-in for typescript-strict-plugin

Reads the same compilerOptions.plugins block and the same // @ts-strict-ignore pragma. Keep your config, swap tsc-strict for tsgo-strict.

🛠️

CLI + programmatic API

Use it from your scripts, your CI, or a Node process via the run() API that returns structured diagnostics and per-phase timings.

📦

Prebuilt native binaries

Ships as an npm launcher with per-platform packages — Linux (gnu/musl, x64/arm64), macOS (x64/arm64), Windows x64. No build step on install.

Install

bash

npm install --save-dev @coralogix/tsgo-strict typescript@^7
# or
pnpm add -D @coralogix/tsgo-strict typescript@^7

Requires a native TypeScript compiler — TypeScript 7+, or @typescript/native-preview if your app isn't on v7 yet (install that instead and tsgo-strict uses it without touching your app's typescript).

Quickstart

Add a plugin block to your tsconfig.json:

jsonc

{
  "compilerOptions": {
    "plugins": [
      {
        "name": "typescript-strict-plugin",
        "paths": ["./src/strict", "./src/shared"],
        "excludePattern": ["**/*.test.ts"]
      }
    ]
  }
}

Then run the checker:

bash

npx tsgo-strict

Files under paths are checked under strict mode. Everything else stays on your normal tsconfig — and its diagnostics are filtered out of the output. Drop a // @ts-strict or // @ts-strict-ignore at the top of any file to override the config for that single file.
