Risteys

The project is based on the Phoenix web framework. This framework is written in elixir, which is also used to do data pre-processing and import into the database. The front-end interactions are using Vue.js. Communication between Vue.js and the backend is done using Phoenix Channels (which runs on Websockets).

Setting up a development environment

Requirements

• elixir

• node.js

• PostgreSQL database

Configuration

Create a file dev.secret.exs in the config/ directory, with the following content and replacing the <VAR>:

dev.secret.exs

use Mix.Config

# Configure your database
config :risteys, Risteys.Repo,
  username: "<USER>",
  password: "<PASSWORD>",
  database: "<DBNAME>",
  hostname: "<HOSTNAME>",
  pool_size: 10

First time dependency initialization

From a terminal in the project root directory (i.e. risteys_elixir), run:

• mix deps.get to get the Elixir dependencies

• mix ecto.setup to create the DB and apply the migrations

• change directory to assets/ and then npm install to install the Javascript dependencies

Running

First, generate a secret key that will be used for storing cookies: mix phx.gen.secret

This should start a development server that will watch for any changes in the code that you are working on and compile / bundle it. You can now access Risteys from http://localhost:4000

Importing data

Import scripts should be run in this order:

1. import_icd10.exs

2. import_icd9.exs

3. import_endpoint_csv.exs

4. import_ontology.exs

5. import_aggregated_data.exs

6. import_coxhr.exs
