deno task is slowly becoming my go-to way of running package.json#scripts, even in Node.js projects, because I don't need to worry whether my dependencies are all installed or if I first have to run npm install.

It works for basic scripts, but it breaks in the case of a script calling another one through npm run (if you want an example, try running deno task build-loose and deno task build in https://github.com/tc39/proposal-defer-import-eval/). It would be great if it worked in that case, and I can think of three ways to do so:

• blindly replace npm run with deno task in the executed command
• alias npm to some intermediate program, that dispatches npm run to deno task and everything else unchanged to the real npm
• create a .bin folder in the node_modules folder that Deno generates, so that the real npm is able to find the scripts it needs to run
