tsc-watch

tsc-watch is a utility that wraps the TypeScript compiler's --watch mode and adds lifecycle hooks to execute commands on compilation events such as success, failure, or first success. It is commonly used as a drop-in replacement for nodemon in TypeScript projects to restart a Node.js server after successful recompilations. The current stable version is 7.2.0, with a release cadence of several minor versions per year. Key differentiators include built-in support for debounced file emission events, signal handling, and the ability to run arbitrary commands without needing an additional process manager. Unlike plain tsc --watch, tsc-watch provides fine-grained control over development workflows and integrates seamlessly with TypeScript's existing compiler options.
