 A tsc wrapper with many convenient features.
+
+## Highlight
+
+- Same usages as `tsc` with few additional options.
+- Remove output folder before before every compilation.
+- Copy non-ts files to output folder after every compilation.
+- Execute js file after compilation success.
+- Respect `tsconfig.json`.
+- ESM.
+
+## Install
+
+```sh
+npm install typescript @nrm/tscx
+```
+
+## Usages
+
+```sh
+# Equivalent to `npx tsc`
+$ npx tscx
+
+# Equivalent to `npx tsc --project tsconfig.build.json --watch`
+$ npx tscx --project tsconfig.build.json --watch
+
+# Remove output folder before before compilation and then compile ts code.
+$ npx tscx --remove
+
+# Compile ts code and then copy non-ts files to output folder after compilation.
+$ npx tscx --copyfiles
+
+# Compile ts code in watch mode and execute bootstrap.js after every compilation success.
+$ npx tscx --project tsconfig.build.json --watch --exec ./bootstrap.js
+
+# Remove => Compile => Copy => Execute => Edit files to repeat it
+$ npx tscx --project tsconfig.build.json --watch --remove --copyfiles --exec ./bootstrap.js
+```
