Dojo Porting Guide: 0.4.x to 0.9

Submitted by leesakcp on Fri, 03/02/2007 - 05:51.

Dojo 0.9 is the future of Dojo. It is backwards-incompatible with all previous Dojo releases. This guide outlines all public API changes between 0.4.x and 0.9. In some cases, functions or modules might have been removed. In these cases, alternative ways to achieve the same goal with 0.9 APIs is outlined.

How To Help

This porting guide is a living thing. If you're a Dojo committer and you're working on a module, please get your changes listed here so that others can benefit from them. If you're porting an application and discover things that aren't yet documented (or documented well) in this guide, don't hesitate to ping me (alex at dojotoolkit.org) for editing permissions on the guide to help improve it. In the mean time, please file comments on the guide pages so we don't lose your discoveries and hard-won helpful hints to your fellow Dojo users.

One of the Dojo contributors wrote a very useful blog on this subject you may find helpful, as well: http://wolfram.kriesing.de/blog/index.php/2007/dojo-migration-04-to-09

dojo.declare

Submitted by tjcrowder on Wed, 07/11/2007 - 11:03.

Folks,

Need to mention the change to dojo.declare.

The 0.4.x way: The initializer is an element in the class body's associative array using the special key "initializer":

dojo.declare("ClassName", null, {
initializer: function() {
// Your initializer code here
},

someMethod: function() {
// Your code for "someMethod" here
}
});

The 0.9 way: It's a third parameter to dojo.declare, not in the class body's associative array, and so it doesn't have a key (as it's not in the array):

dojo.declare("ClassName", null,
function() {
// Your initializer code here
},
{
someMethod: function() {
// Your code for "someMethod" here
}
});

The initializer param is optional. Refer to dojo.declare's documentation for details.

Really?

I just ported an app to 0.9 and I get warnings if I dont do it like this:

dojo.declare("ClassName", null, {
constructor: function() {
// Your initializer code here
},
someMethod: function() {
// Your code for "someMethod" here
}
});

is the above comment wrong or is it because I am using the svn-head?

It changed

Hiya,

Good catch, it changed between the beta and the release. :-) In 0.9Beta, the initializer was a new third param, but apparently (I've been on holiday and buying a house, so I've been out of the loop lately) before release it went back to being a "constructor" method in the props.

Thanks for pointing that out!

on dojo.declare

Submitted by patb23 on Wed, 10/31/2007 - 15:21.

Hi,
I am a newbie and started with dojo 0.9. I am also using aptana IDE.
The problem I have is that I am not able to import rpc package. dojo.require("dojo.rpc.*") gives me an error in firebug console that __package__.js is not found. I tried the same thing with dojo 0.4 - it is working.

I looked at the porting guide and I do not see any change related to this import. I have also read the short cut from orielly but could not find any information related to this.

Could anyone let me know what is the mistake?

note: The dojo structure has a src subfolder.
