This is a modification of the Todo MVC app for Reagent demonstrated here. This version of the app has been modified to use a PostgreSQL database to store the Todos and to provide realtime synchronization of changes to that data to any number of users currently viewing the app.

This example app uses a PostgreSQL database. The SQL script to create it is in create_db.sql.

A Docker compose file pgsql.docker-compose.yml is provided and pre-configured to allow you to quickly spin up a PostgreSQL database that will be pre-initialized via create_db.sql through Docker.

$ docker-compose -f pgsql.docker-compose.yml up

Alternatively, if you already have a PostgreSQL database available, you can run the create_db.sql via psql easily enough:

$ psql < create_db.sql

(Of course, add any username/host parameters you might need)

To build everything and run in one step:

$ lein rundemo

Then open up a web browser or two and head to http://localhost:8080/ to see the web app in action.

If you want to run this application in a REPL, just be sure to build the ClojureScript:

$ lein cljsbuild once

And then in the REPL you can just run:

(-main)

to start the web app (you should be put in the correct namespace immediately).
