How publish and use the npm packages

My module

npmpublicrepo -- package.json -- test.js

package.json

   {
  "name": "npmpublicrepo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

test.js 

exports.testMessage = function() {
   console.log("test");  
};

npm publish

This got successfully published and I can see the page in npm

https://www.npmjs.com/package/npmpublicrepo

My normal project to use above package

npmpublicrepousage -- package.json -- index.js

package.json

{
  "name": "npmpublicrepousage",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "npmpublicrepo": "^1.0.0"
  }
}

after doing npm install, I can see the folder in ./node_modules/npmpublicrepo and I am able to see the module's code properly.

Running a script which use the module

Then, I use the previous module in the script ./index.js :

var test = require("npmpublicrepo");
test.testMessage();

But, running the script fails :

node ./index.js

...with the error :

module.js:472
    throw err;
    ^

Error: Cannot find module 'npmpublicrepo'
    at Function.Module._resolveFilename (module.js:470:15)

    at tryModuleLoad (module.js:447:12)
    at Function.Module._load (module.js:439:3)

I don't know what i am missing.

My node version : v7.4.0

My NPM version : 4.0.5

In your npmpublicrepo package.json you expose a wrong primary entry point to your program. You set a file that does not exist:

"main": "index.js"

You could rename test.js to index.js or you could expose the test.js file as the primary entry point to your program with:

"main": "test.js"
