Syndemicexplorer

A proof of concept for a COVID19 "syndemic" dashboard

Pre requisites

You need nodejs installed and a running instance of PostgreSQL.

To setup the database, you can use Docker:

docker run --name syndemicdb -e POSTGRES_PASSWORD=syndemic -p 5432:5432 -v /path/to/src/initsql:/docker-entrypoint-initdb.d -d postgis/postgis:13-3.1

change /path/to/src/initsql to the actual path.

This will create a running instance of Postgres with Postgis and preloaded maps for Sweden. The database name, username and password are specified inside the file /initsql/0_structure.sql Feel free to change them there.

Create a .env file inside the root folder of this project like the follwing:

PORT=5000
PG_HOST=localhost
PG_PORT=5432
PG_DATABASE=syndemic
PG_USER=syndemic
PG_PASSWORD=syndemic

Make sure the details for connecting to the database are correct.

Run

node ./src/app.js 

Develop

Dump of stuff I need later:

docker exec -it syndemicdb /bin/bash

latitude: ST_Y(ST_Centroid(geom))

longitude: ST_X(ST_Centroid(geom)),

docker run --name syndemicdb -e POSTGRES_PASSWORD=syndemic -p 5432:5432 -v /Users/aj6373/Documents/Research/Projects/covid19db/syndemicexplorer/src/initsql:/docker-entrypoint-initdb.d -d postgis/postgis:13-3.1
