custom npm scripts

You can define your own scripts in package.json, like:

  "scripts": {
    "fix-tags": "node app.js tags/index.html"
  }

and you can run them like this:

npm run-script fix-tags

node javascript npm

install bower components on heroku build

Make sure you have bower added as a dependency in package.json, and then add the following script as postinstall:

}

asset digest in node.js

node-static-asset can help with this.

Like the docs say, add this to your app:

var express = require('express');
var app = express();
var staticAsset = require('static-asset');
app.use(staticAsset(__dirname + "/public/") );
app.use(express.static(__dirname + "/public/") );

And then in the view, use it like this:

script(type="text/javascript", src=assetFingerprint("/javascripts/jquery.min.js") )

node javascript asset
