### Technical setup details (local testing):

1. Run the `dev_init()` function found in the `scripts/dev_init.R` file:

```
    source("scripts/dev_init.R"); dev_init()
    ```

A SQLite database `cranalerts.sqlite3` will be created.

2. If you have an SMTP server settings and would like to send emails, create a `config.yml` file in the root directory using the template of [`config.yml.sample`](./config.yml.sample), and edit all the values to match your settings.

### Technical setup details (production):

1. Create a SQLite database

```
    sqlite3 cranalerts.sqlite3 < init_cranalerts_db.sql
    ```
    
    Make sure to make the database file readable/writeable to the owner and group, so that both shiny and cronjobs will be able to write to it

2. Create a `config.yml` file in the root directory using the template of [`config.yml.sample`](./config.yml.sample), and edit all the values to match your email server settings.

3. Install `rJava` package (for email sending using `mailr`) and configure it. I was having a lot of trouble getting it to work, it seems that it was not working with Java 11. I had to follow these steps after already having Java 11 installed:

- Run `apt install openjdk-8-jdk openjdk-8-jre`
   - Run `update-alternatives --config java` (since I already had java 11 and I wanted to downgrade)
   - Add java paths to environment `/etc/environment`: `JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64` and `JRE_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre`
   - (Reboot machine so that the envvars get loaded or set the environment variables temporarily)
   - Make sure the path is set and java 8 is used: `printenv JAVA_HOME` and `java -version`
   - Run `R CMD javareconf` to set up java with R
   - Now installing `rJava` pacakge should work, and sending emails with `mailR` should work

4. Set up a cron job (`crontab -e`) to run the update script (the following results in the script running daily at 13:00)

```
    0 13 * * * /srv/shiny-server/cranalerts/scripts/run_cranalerts_script.sh > /srv/shiny-server/cranalerts/scripts/run_cranalerts_script.log 2>&1
    ```
