tsc-watch
Advanced tools
Package description
The tsc-watch npm package is a utility that allows you to run the TypeScript compiler (tsc) in watch mode and execute custom scripts when certain events occur, such as when compilation starts, succeeds, or fails. This is particularly useful for automating tasks during development, such as running tests or restarting a server.
Run TypeScript compiler in watch mode
This feature allows you to run the TypeScript compiler in watch mode, which means it will automatically recompile your TypeScript files whenever they change. The `--onSuccess` flag specifies a command to run whenever the compilation succeeds. In this example, it runs a Node.js script located at `./dist/index.js`.
tsc-watch --onSuccess "node ./dist/index.js"Run custom scripts on compilation failure
This feature allows you to specify a command to run whenever the TypeScript compilation fails. In this example, it simply echoes 'Compilation Failed!' to the console.
tsc-watch --onFailure "echo Compilation Failed!"Run custom scripts on compilation start
This feature allows you to specify a command to run whenever the TypeScript compilation starts. In this example, it echoes 'Compilation Started!' to the console.
tsc-watch --onCompilationStarted "echo Compilation Started!"Nodemon is a utility that monitors for any changes in your source and automatically restarts your server. It is language-agnostic and can be used with any executable, not just TypeScript. Unlike tsc-watch, nodemon does not handle TypeScript compilation by itself; you would need to use it in conjunction with the TypeScript compiler.
ts-node-dev is a development tool that combines ts-node and nodemon. It watches for changes in TypeScript files and restarts the Node.js process automatically. Unlike tsc-watch, ts-node-dev directly executes TypeScript files without needing a separate compilation step.
Webpack is a module bundler that can be configured to watch for changes in your files and recompile your project. With the appropriate loaders, it can handle TypeScript files. Webpack is more complex and powerful than tsc-watch, offering features like code splitting and hot module replacement.

Readme
tscw starts the tsc (TypeScript compiler) with --watch parameter, it also adds a new argument --onSuccess COMMAND. this COMMAND will be executed on every successful TypeScript compilation.
Notes:
COMMAND will not run if the compilation failed.COMMAND) will be terminated before creating a new one.tscw is using the currently installed TypeScript compiler.tscw is not changing the compiler, just adds the new arguments, compilation is the same, and all other arguments are the same.tscw was created to allow an easy dev process with TypeScript. Commonly used to restart a node server.FAQs
