# Atju Backend

[![Deploy](https://www.herokucdn.com/deploy/button.svg)](https://heroku.com/deploy)

Atju is a project for monitoring pollen readings in Denmark. Data is obtained from DMI. The application polls DMI for new pollen readins and stores them in a database. The readings are exposed through a tiny API. The readings can be viewed using the [Atju iOS app](https://github.com/simonbs/atju), which is also open source.

## Installation

You can deploy to Heroku by pressing the above button or you can deploy manually using the following steps.

1. Install the necessary dependencies by running `npm install`.

2. Make sure that you have PostgreSQL running. 

3. Create a database named "atju". The database can typically be created by running `createdb atju`.

4. Modify `config/default.json` as necessary.

5. Set the environment variable `DATABASE_URL` to the a URL pointing to your PostgreSQL or MySQL database.

6. Set the environment variable `URBAN_AIRSHIP_APP_KEY` to the Urban Airshp app key.

6. Set the environment variable `URBAN_AIRSHIP_APP_SECRET` to the Urban Airshp app secret.

6. Set the environment variable `URBAN_AIRSHIP_MASTER_SECRET` to the Urban Airshp master secret.

### Configuring tasks

If you deployed to Heroku, you'll want to add the following two tasks to Heroku Scheduler, otherwise you'll want to configure the two tasks as cronjobs.

1. Run `npm run refresh` to check for new pollen readings. Doing this every hour should be sufficient. This will also notify the users when new readings become available in their area.

2. If you want to receive the prognose for a a day, run `npm run sendprognose` at the time you wish to receive the prognose, e.g. at 7 in the morning.

## Running the application

Run the app in a development environment using `npm run start-dev` and in a production environment using `npm start`.

The app will poll DMI for new pollen readings every 15 minute when run in a production environment. When running in a development environment, you can run `npm run refresh` to poll for new readings.
