使用别名调用 JavaScript 或 Node.js 程序

Question

I am writing a JavaScript program that needs to invoked on the command line using a special command/alias. Instead of typing node fileName.js , I need to be able to just type newFile to run it. My understanding (correct me if I'm wrong) is that I could create a Bash script to run the JavaScript and use an alias to run that. But I would like to avoid using a Bash script if I can.

I looked into Node to see if I can do this. All I found was information about putting the name of the program in the package.json file, as a value for "start", under "scripts." But then to run the program I would have to type npm start . I looked for a way that I could create an alias for npm start within Node itself, but I didn't find one.

Is there a way to do what I want, with or without Node, without using an external script?

Answer 1

No you can't... It might possible with shell script. But in your machine node js run with help of npm.

Every javascript project has a package.json file which is managed package file for your project. So you can not do what you want.

What I suggest: Use nodemon.

npm i nodemon

then in package.json add another script "dev" or whatever you want or you can write under start script.

"dev":"nodemon app.js",

Then everytime you save your application your server will restart automatically

Note: Each time you copy or select something from command prompt while using nodemon; dont forge to press rs
