A year or so ago I spent a few hours writing an IPv4 subnet calculator in javascript. I didn’t have any real goal, just a desire to play with javascript. I promptly forgot about it. Then a month or so ago I found it again and dusted it back off. I had a lot of fun rewriting it and then… forgot about it again.<\/p>\n
After remembering it yet again last night, I decided enough was enough, filed the roughest edges off of it, and posted it:<\/p>\n
Ippsy, The Experimental Javascript Application<\/a><\/strong><\/p>\n <\/p>\n There’s not a lot of use to the internet at large in this tool (no one needs yet another IP Calculator), but the core of this app is written such that other screens\/functions\/pages\/tools can be added to it. At some point I’ll get a wild hair to add something new and this frame will be available to do it.<\/p>\n There are a couple of design rules that I think make this project interesting. The first is that I intend it to never grow beyond a single HTML page with Javascript and CSS embedded directly in it. This is not the greatest design choice for manageability, but my goal is that this tool is not a “website”, it’s an application that runs in a browser. By making it a single HTML page app distribution is as simple as “save as”.<\/p>\n The second design choice, which is really driven by the first, is that I won’t use any external frameworks. No jQuery, no ExtJS, etc. I want to build this in relatively pure HTML\/Javascript\/CSS, while still making the site as pretty as possible (which it is not right now, I admit).<\/p>\n One specific goal I have not set it legacy browser version support. There’s nothing in the tool right now that’s especially troublesome for older browsers, but I won’t much care if I introduce a problem in the future. The app is very specifically targeted at “the browser I am using right now”, and more loosely targeted at “the last version or two of the bigger browsers”.<\/p>\n There, I published it. Now I can forget about it again for another year and see if anyone finds it…<\/p>\n","protected":false},"excerpt":{"rendered":" A year or so ago I spent a few hours writing an IPv4 subnet calculator in javascript.
