How to run the demo

Run PostgreSQL

You need a version that has logical decoding enabled. Use docker:

docker run -p5432:5432 --name postgres94maps -d sebastianharko/postgres94

Connect to database

Connect to database using (some GUI).

port = 5432
host = localhost
database = pgdb1
user = pguser
password = pguser

Create table


DROP TABLE IF EXISTS "public"."users";
CREATE TABLE "public"."users" (
  "id" int4 NOT NULL,
  "lat" float8 NOT NULL,
  "lng" float8 NOT NULL
);

ALTER TABLE "public"."users" ADD CONSTRAINT "users_pkey" PRIMARY KEY ("id");

Look at map

sbt run

Open browser at http://localhost:8080/map.html

Insert Random Data

Insert a random user:

INSERT INTO users VALUES(floor(random()*1024), floor(random()*(40-25+1))+25, -1 * (floor(random()*(120-80+1))+80));
