To acquire AspectJS, click on the link below to download the code as a Zip file. Alternatively, the code that defines the AJS and AJS_HP objects can be copied and pasted from the Copy & Paste AJS and Copy & Paste AJS_HP pages respectively. See the end of this page, the reference listings in the zip file, or the Copy & Paste pages for the licence terms.

Download Aspect_JS v1.0

Note that, while the product is available here in 'minified' form (ie. without redundant white-space) it is not provided in obfuscated (or 'scrunched') form, where all objects and functions that do not form part of the documented API are renamed using (ideally) single alphabetic-characters. Nor is it available in 'gzipped' form (modern browsers will accept scripts as .gz files).

Scrunching 'script-oriented' code expedites download to the client, and the parsing process thereon. Moreover, applying gzip to a scrunched listing improves the first factor still further. However, and by definition, scrunching also makes the code extremely difficult to understand, and gzip renders it unreadable. Given this, it would be possible for a malign version of AspectJS to originate here and find its way ultimately onto users' machines (thus contradicting the third term in the licence under which the product is made available).

Given this, and if you are seeking minimal overhead in the deployment of your applications (and good on you for that), you alone are responsible for any obfuscation/compression that you apply before deploying AspectJS as part of a bigger application.

The upside, however, is that experiments with various scrunchers on the code for the AJS object indicate an average reduction in size of around 55%. Moreover, gzipping a scrunched version yields a total size-reduction of around 90%, and similar reduction ratios can be expected with the code for the AJS_HP object. These figures are impressive and make the trouble of a scrunching/compression deployment-phase worth considering. Do note, however, that obfuscators/scrunchers can introduce bugs into a given script.
