olizilla / withCanvas.js
Created January 3, 2011 09:05
olizilla gets up close and functional with javascript. withCanvas provides a temporary canvas to another function, and always remembers to clean up after itself.
// Provide a function with a temporary canvas, encapsulating the creation and clean up code.
function withCanvas(/*canvas => Any*/ use) {
var b = document.body;
// create canvas
var canvas = document.createElement("canvas");
// canvas doesn't draw well unless it's added to the page
b.appendChild(canvas);

How to Node, NPM, Grunt, Git and Heroku

Problem: I'd prefer not to commit compiled resources to my repository, but I've still gotta deploy the thing.

Simple solution: Commit compiled resources...

Bonus credit solution: npm postinstall task runs grunt, grunt creates the compiled resources, heroku can then automagic on git push, rainbows and unicorns ensue.1,2

Your milage may vary, but on the happy path a git push heroku can deploy and run your node app.

Getting grunt to do your bidding is covered elsewhere. GRUNTEND is a fine bootstrap to getting your HTML5 Boilerplate app rolling on grunt: https://github.com/alanshaw/gruntend

From webapp sludge to a working Eclipse project deployed to local Tomcat

How to eclipsify a bad webapp

Assumptions

  • Tomcat 7 is available and imported into eclipse
  • Eclipse Juno, EE flavour.

Any mismatch between these assumptions and reality may result in failures and face-palm.
