package.json bin

【package.json bin】

1、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:

　　

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

2、run-scripts

　　npm run adds node_modules/.bin to thePATH provided to scripts. Any binaries provided by locally-installed dependencies can be used without the node_modules/.bin prefix. 

　　For example, if there is adevDependency on tap in your package, you should write:

　　

　　instead of "scripts": {"test": "node_modules/.bin/tap test/*.js"} to run your tests.
