Goldly

• goldly is a vizualization tool for clojure
• inspired by R/shiny
• brings many vizualizers
  • vega and highcharts for 2d plotting
  • aggrid for tables/ grids
  • leaflet for geographic map
  • quil for 2d dynamic animations
  • vizualizers can be easily extended. you can access the entire npm + clojurescript ecosystem. An example for a simple ui extension is ui-binaryclock
• uses the sci clojurescript interpreter for dynamic ui interactions at runtime
• load data from clojure (from the frontend app)

usecases

• visualize edn datastructures (either from a repl or in the web-app (via sratchpad)
• quickly write a web dashboards (by using only clojure).
  • EDGAR uses it to vizualise mutual fund holdings
  • trateg uses it to vizualize swing charts
• goldly systems can be used in a Notebook.

How to setup goldly

You have two options:

• use goldly-bundel dependency, which ships a pre-built javascript budle and already includes many ui-renderers.
• use goldly to build javascript bundle from scratch. This takes more time (everything needs to be compiled), but it allows you to add custom ui renderers to your goldly app

Setup Goldly-Bundel

goldly-bundel is identical to goldly, it only brings the compiled javascript bundel as resources.

To start the goldly via goldly-bundel:

clojure -Sdeps '{:deps {org.pinkgorilla/goldly-bundel {:mvn/version "0.2.35"}}}' -m goldly-server-bundel.app

Setup Goldly with custom ui-renderers:

This configures goldly with your set of ui-renderers.

You have to include the goldly and ui-renderer dependencies, and then add the namespace of the ui-renderer to goldly/extensions. This allows goldly to add the ui extensions to the javascript bundle.

This example adds gorilla-ui to goldly:

for tools.deps Add this alias to your deps.edn:

 :goldly
  {:extra-deps {org.pinkgorilla/goldly {:mvn/version "0.2.39"}
                org.pinkgorilla/gorilla-ui {:mvn/version "0.3.21"}}
   :exec-fn goldly-server.app/goldly-server-run!
   :exec-args {:profile "watch"
               :config {:goldly {:extensions [[pinkgorilla.ui.goldly]
                                              ]}}}}

for leiningen Add the alias to project.clj

{:alias
   "goldly"
   ["with-profile" "+goldly" "run" "-m" "goldly-server.app" "watch" "goldly-gorillaui.edn"]}

Add a goldly-gorillaui.edn:

{:goldly {:extensions [[pinkgorilla.ui.goldly]]}}

run the demo (in this project)

run goldly without ui-extensions

clojure -X:goldly

• Then open browser http://localhost:8000
• In the browser window click on running systems and then snippet registry
• You are able to click on all the systems in he registry.

The source code of the registry systems is in src/systems. The snippets are in resources/snippets/

The snippets are primitive, but demonstrate certain features of goldly:

• hello: demonstrates the simplest hiccup rendering usecase
• click-counter demonstrates dynamic ui intteractions.
• greeter: shows how to create links from one system to another; this can be used for master-detail type of navigation.
• fortune: demonstrates how to load data from clojure (could be a database)
• time: demonstrates to push data from clojure

run goldly with bundel ui-extensions

clojure -X:goldly-bundel

This is the same config as in goldly-bundel, but the javascript bundel is generated on the fly.
