I'm having a surprisingly hard time finding an answer to this. With plain Node.JS, you can run any js file with node path/to/file.js, with CoffeeScript it's coffee hello.coffee and ES6 has babel-node hello.js. How do I do the same with Typescript?
My project has a tsconfig.json which is used by Webpack/ts-loader to build a nice little bundle for the browser. I have a need for a build step run from the console before that, though, that would use some of the .ts files used in the project to generate a schema, but I can't seem to be able to run a single Typescript file without compiling the whole project.
You can leave tsc running in watch mode using tsc -w -p . and it will generate .js files for you in a live fashion, so you can run node foo.js like normal.
To run a single TypeScript file without compiling the whole project, there is ts-node that will compile the code on the fly and run it through Node:
npx ts-node src/foo.ts
