This is an attempt at defining arbitrary data lineage graph via small composable specification files which can describe data (:data), transformations (:data-transformations) and data types (:data-types) in any combination and then visualize it in some meaningful way. Then for each piece of data you can trace all incoming and outcoming nodes, which can help you understand the lineage better. For now graph is renderd using GraphViz, but maybe I'll come with proper visualization (D3, maybe) in future.
To start the Figwheel compiler, navigate to the project folder and run the following command in the terminal:
lein figwheel
Figwheel will automatically push cljs changes to the browser. The server will be available at http://localhost:3449 once Figwheel starts up.
Figwheel also starts nREPL using the value of the :nrepl-port in the :figwheel
config found in project.clj. By default the port is set to 7002.
The figwheel server can have unexpected behaviors in some situations such as when using websockets. In this case it's recommended to run a standalone instance of a web server as follows:
lein do clean, run
The application will now be available at http://localhost:3000.
Start the browser REPL:
$ lein repl
The Jetty server can be started by running:
(start-server)and stopped by running:
(stop-server)lein do clean, uberjar
