To install:

npm install ensure-latest --save

Add the script hook to your package.json:

"scripts": {
    "preinstall": "[ -e ./node_modules/ensure-latest/index.js ] && node ./node_modules/ensure-latest || echo"
},

Finally, mark the modules that you want to ensure are latest in your package.json:

"ensureLatest": [ "grunt", "mocha" ],
"ensureLatestAlpha": [ "titanium" ]

Now whenever you run npm install, you will see logging from ensure-latest!

If everything is up to date:

> npm install

> node ./node_modules/ensure-latest/run.js

Making sure we are using the latest versions of certain modules...
Ensured modules are up to date!
> 

Or, if an update is available:

> npm install

> node ./node_modules/ensure-latest/run.js

Making sure we are using the latest versions of certain modules...
- Updating arrow from 0.3.35 to 0.3.38
Updated package.json with new module versions!

Followed by npm installing the new version.

Enjoy!
