DOM Templating and Interpolation



bson2json: just a quick & dirty converter, BSON→JSON, and rudimentary schema analysis, for preparing to migrate a MongoDB dump to LevelDB.


Hacked Teacup: Double Macchiato

Teacup (HTML templating in CoffeeScript) is a fantastic DSL (domain specific language). Less “specific” than Jade, but it’s a programming language, so the potential for extending is exciting! I’ve been writing “helpers” to abstract HTML details, make my templates a higher level DSL.

But, although Teacup has nice facilities for extendibility, it’s restricted by its rendering architecture: a single pass, depth first recursion, immediately rendering CS→HTML. This limitation obviously prevents post-processing of nested contents by wrappers higher up the call stack, given, of course, we don’t want to manipulate/parse rendered HTML — that would smell wrong, and require a complex and slow full parser… which really misses the point.

Two use cases I’m sorely missing: patching any nested content to, eg, provide defaults, and freely composing helpers, eg:

# Allow wrapping immediate calls:
mockup initially_hidden screen '#home'
# But also support wrapping callbacks:
mockup ->initially_hidden ->screen '#home'

(First form calls inner, then wrapper; second form — reversed order.)

Thus, Teacup must be hacked!


Constitution: a Method

Systematic web apps development (notes towards…). The method I follow with my still work in progress Constitution stack.

Bmeter: Pure Client Side Single Page App

Hackathon, yay!

I was tasked with upgrading the Bchirometer, a simple single page app (SPA), to a narrow (first?) UI, given a bunch of sketches in PNGs.

Rewriting, really. Repo was a mess of drafts, and… nu.

App uses Open Knesset‘s data, but otherwise it’s independent — separate (sub)domain. Not even same servers: it’s on S3, because pure client side, aka static.

(I still (it’s 2015!) can’t understand why open/activist projects use obsolete technologies: Django, Bootstrap, and other, unmentionable, crap. What would Ivan Illich have said? I’m still revolting against “worse is better“.)


Stepping Into Node Streams Twice

CLI for transforming some JSON — Chromium’s bookmarks, specifically — into HTML, for quick (and dirty) publishing here.

And while we’re at it, let’s ponder Node streams again?


LevelUP: Promises, Promises…

Promisifying LevelDB in Node to escape callback hell…



Notes towards…


Express Authentication

Authentication (and authorization?) with Express for RESTful APIs.

As usual with Node, too many existing solutions — and their documentation sucks.
