無需node-gyp和安裝後腳本的快速TypeScript/JavaScript轉換器。

用法

使用節點執行 TypeScript，無需編譯或類型檢查：

npm i -D @swc-node/register
node -r @swc-node/register script.ts
node --import @swc-node/register/esm-register script.ts # for esm project with node>=20.6
node --loader @swc-node/register/esm script.ts # for esm project with node<=20.5, deprecated

將--enable-source-maps傳遞給 esm 專案的節點

當您想要載入 .swcrc 檔案時，設定環境變數 SWCRC=true

SWCRC=true node -r @swc-node/register script.ts

#!/usr/bin/env -S node --import @swc-node/register/esm-register

// your code

使用 shebang 運行，新增TS_NODE_PROJECT=null ( #!/usr/bin/env TS_NODE_PROJECT=null node --import @swc-node/register/esm-register ) 以使用ignore tsconfig.json

性能一覽

在純TypeScript專案中測試，編譯目標是ES2018 。使用npx jest --no-cache運行， ts-jest配置為isolatedModules: true
