React is the new Dojo

2017-10-20T00:22:01+00:00

In which Mikeal Rogers provides his perspective on the history of Dojo, the earliest break-out JavaScript framework, how jQuery eclipsed it and contemplates the same thing eventually happening to React.

Why do so few companies use the Dojo Toolkit?

2010-10-11T17:14:00+00:00

My answer to Why do so few companies use the Dojo Toolkit? on Quora

Dojo is fantastic software, but it does a lot more than the other libraries and consequently has a much higher learning curve. It's advanced features may serve as something of a disadvantage for achieving more widespread adoption - most developers don't need the more advanced abstractions provided by Dojo when they start their projects, and by the time they DO need that stuff they've already written a ton of code using another library!

node-v0.1.30

2010-02-22T19:00:47+00:00

node-v0.1.30

A very significant new release of Node.js: the Twisted/Dojo-style Promise abstraction has been removed entirely, causing backwards incompatible changes to a bunch of core APIs. This means the pseudo-blocking Promise.wait() method is gone too, making it even harder to accidentally block your event loop. Instead, user-level libraries are encouraged to add Promise-style abstractions. I’m pleased to see Node sticking to the low-level stuff.

Dojo: Still Twice As Fast When It Matters Most

Dojo: Still Twice As Fast When It Matters Most

Alex Russell shows how Dojo out-performs jQuery on the TaskSpeed benchmark, which attempts to represent common tasks in real-world applications and has had code that have been optimised by the development teams behind each of the libraries.

It’s interesting to me how much [Closure] feels like a more advanced version of Dojo in many ways. There's a familiar package system, the widgets are significantly more mature, and Julie and Ojan's Editor component rocks. The APIs will feel familiar (if verbose) to Dojo users, the class hierarchies seem natural, and Closure even uses Acme, the Dojo CSS selector engine.

Coupling asynchronous scripts

More from Steve Souders, this time discussing methods to cause externally loaded scripts to execute in the correct order, obeying dependencies. Surprisingly there’s no mention of YUI loader or the Dojo packaging system.

Dojo 1.3 now available

2009-04-01T00:19:25+00:00

Dojo 1.3 now available

Looks like an excellent release. dojo.create is particularly nice—I’d be interested to know why something similar has never shipped with jQuery (presumably there’s a reason) as it feels a lot more elegant than gluing together an HTML-style string. Also interesting: you can swap between Dojo’s Acme selector engine and John Resig’s sizzle.

Secure mashups with dojox.secure

2008-09-24T16:08:56+00:00

Secure mashups with dojox.secure

dojox.secure is brilliant and terrifying at the same time. It provides a full featured API for running untrusted JavaScript in a sandbox, by parsing and validating that code against a variant of Douglas Crockford’s ADsafe JavaScript subset. It could be fantastically useful, but it’s difficult to judge how secure this approach really is.

Making queries faster isn't in the critical path for improving the real-world performance of any Dojo apps I know of, and I bet the same is true for JQuery users. Reducing the size of the libraries, on the other hand, is still important. Now that we're all fast enough, it's time that we stopped beating on this particular drum lest we lose the plot and the JavaScript community continue to subject itself to endless rounds of benchmarketing.

Google AJAX Libraries API

Google AJAX Libraries API

Google are hosting copies of jQuery, Prototype, mooTools and Dojo on their CDN, with a promise to permanently host different versions and an optional JavaScript API to dynamically load the most recent version of a library. I wish they’d stop capitalising Ajax though.

AOP aspect of JavaScript with Dojo

AOP aspect of JavaScript with Dojo

Fantastic post—concisely explains Aspect Oriented Programming, then shows how Dojo’s dojox.lang.aspect brings AOP to JavaScript, including some really useful built-in aspects for logging, profiling and more. Aspects are like Python decorators on steroids.

Embedding custom non-visible data in HTML 5

2008-04-19T22:58:23+00:00

Embedding custom non-visible data in HTML 5

“Every HTML element may have any number of attributes starting with the string ’data-’ specified, with any value.”—this will be incredibly useful for unobtrusive JavaScript where there’s no sensible place to store configuration data as HTML content. It will also mean Dojo has an approved method for adding custom attributes to declaratively instantiate Dojo widgets.
