npm-scripts

问题 I noticed this strange behavior which is not a big deal, but bugging the heck out of me. In my package.json file, under the "scripts" section, I have a "start" entry. It looks like this: "scripts": { "start": "APPLICATION_ENV=development nodemon app.js" } typing npm start on a Mac terminal works fine, and nodemon runs the app with the correct APPLICATION_ENV variable as expected. When I try the same on a Windows environment, I get the following error: "'APPLICATION_ENV' is not recognized as

问题 Since it is not necessary to have package.json file with deno, how can I as a developer have a similar experience just as we have with npm scripts in package.json ? 回答1: deno install You can create executable, aliased scripts with deno install. It will provide a thin shell/cmd wrapper for the specified main module and CLI arguments. Example: deno install --root . -n serve --allow-read --allow-net https://deno.land/std@0.54.0/http/file_server.ts The result is a serve script, similar to npm
