Using JavaScript Libraries from ClojureScript

Using JavaScript libraries from ClojureScript involves two distinct concerns:

Packaging the code and delivering it to the browser
Making ClojureScript code that accesses JavaScript libraries safe for advanced optimization

Right now, the only single tool that solves these probems reliably, optimally, and with minimal configuration is shadow-cljs, and so that is what I favor. In paricular, shadow-cljs lets you install npm modules using npm or yarn and uses the resulting package.json to bundle external dependencies. Below I describe why, what alternatives there are, and what solutions I disfavor at this time.

Packaging and Delivering Code

1. Load and transform `TietoaKuntajaosta_2017_4500k.zip` from `kartat.kapsi.fi`

wget "http://kartat.kapsi.fi/files/kuntajako/kuntajako_4500k/etrs89/shp/TietoaKuntajaosta_2017_4500k.zip"
unzip TietoaKuntajaosta_2017_4500k.zip
ogr2ogr -f GeoJSON -t_srs crs:84 SuomenKuntajako_2017_4500k.geo.json SuomenKuntajako_2017_4500k.shp

2. Transform and enhance GeoJSON

Send docker logs to ELK through gelf log driver

There's so many way to send logs to an elk... logspout, filebeat, journalbeat, etc.

But docker has a gelf log driver and logstash a gelf input. So here we are.

Here is a docker-compose to test a full elk with a container sending logs via gelf.

	(ns text-field
	(:require
	[goog.object :as gobj]
	[reagent.core]
	;; Note that this particular `:require` vector is for shadow-cljs.
	;; Other build tools might use different conventions.
	["@material-ui/core/TextField" :default TextField]))

	;; Copied from `re-com.util`.
	(defn deref-or-value

	(require '[clojure.set :as set])
