Why Cannot find my own custom module?

Question

I published my own npm module but it cannot find from my sample script.

This is my module

https://www.npmjs.com/package/kong-hmac

https://github.com/y-zono/kong-hmac-js

What I did.

$ mkdir /tmp/sample-myjs
$ cd /tmp/sample-myjs/
$ touch package.json
$ echo "{}" > package.json
$ npm install --save kong-hmac
$ npm install --save-dev babel-cli
$ npm install --save-dev babel-preset-es2015
$ touch test.js
$ echo 'const hmac = require("kong-hmac");' > test.js
$ babel-node --presets es2015 test.js 
module.js:327
    throw err;
    ^

Error: Cannot find module 'kong-hmac'

Any ideas? My module is written in ES2015.

Inside your node_modules look for the package kong-hmac you find lib folder not src and in the package.json of kong-hmac change "main": "src/index.js" to "main": "lib/index.js" .

I guess, while publish a package npm structures the program this way
