The TypeScript compiler with --watch and a new onSuccess argument

tsc-watch 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.

Install

npm install tsc-watch --save-dev

Usage

tsc-watch server.ts --outDir ./dist --onSuccess "node ./dist/server.ts"

Notes:

• The COMMAND will not run if the compilation failed.
• The child process (COMMAND) will be terminated before creating a new one.
• tsc-watch is using the currently installed TypeScript compiler.
• tsc-watch is not changing the compiler, just adds the new arguments, compilation is the same, and all other arguments are the same.
• tsc-watch was created to allow an easy dev process with TypeScript. Commonly used to restart a node server.
