Binary file in npm package

Actually, you can put your myapp.js file into bin.
So, the bin key in package.json file should be like this :

"bin": { "myapp" : "<relative_path_to_myapp.js>/lib/myapp.js" }

At the first line in myapp.js, you must add this shebang line :

#!/usr/bin/env node

It tells the system to use node to run myapp.js.

---

... Or if you don't want to call myapp.js directly, you can create a script like this to be your executable file :

#!/usr/bin/env node

var myapp = require('<relative_path_to_myapp.js>/myapp.js');
myapp.doSth();

and in package.json :

"bin" : { "myapp" : "<relative_path_to_the_script>/script.js" }

By doing this either way, you can avoid finding the path to your nodemodule.

---

But... if you insist to use your old myapp bash script, then you can find the path to the module with this :

myapp_path=$( npm explore -g myapp -- "pwd" )

Hope these help :D

From the above link:

...

To use this, supply a bin field in your package.json which is a map of command name to local file name. On install, npm will symlink that file into prefix/bin for global installs, or ./node_modules/.bin/ for local installs.

For example, myapp could have this:

{ "bin" : { "myapp" : "./cli.js" } }

So, when you install myapp, it’ll create a symlink from the cli.js script to /usr/local/bin/myapp.
