Watching and restarting

ts-node focuses on adding first-class TypeScript support to node. Watching files and code reloads are out of scope for the project.

If you want to restart the ts-node process on file change, existing node.js tools such as nodemon, onchange and node-dev work.

There's also ts-node-dev, a modified version of node-dev using ts-node for compilation that will restart the process on file change. Note that ts-node-dev is incompatible with our native ESM loader.
