External Website

The external website is comprised of two parts:

• A reactjs/D3js website hosted on Apache
• An API that supplies the website with the json data it needs

Reactjs/D3js Website

The source code for the website is currently available here: https://github.com/raubreywhite/sykdomspuls_reactjs

This will be updated soon to:

1. Transfer ownership to https://github.com/folkehelseinstituttet
2. Use http://parceljs.org as a bundling tool instead of webpack
3. Improve D3js code

API On External Webserver {#api}

The external website's API is powered by plumber. Briefly, this is an R package that can convert R data into json and serve it through http requests.

This is done through the RunAPI.R which is run by an R instance on the external webserver.

Signal Processing On SMHB

This R package is triggered via cron. The cronjob calls 0_run.sh which is the enterance point for this package.

When 0_run.sh is called, it firstly uses flock to determine if another instance of sykdomspuls is already running - if so, 0_run.sh exits. Otherwise, RunProcess.R is run, which:

• Checks for unprocessed data
• If there is no unprocessed data, then quits with status=21
• Processes all unprocessed data
• If successful, quits with status=0

0_run.sh then checks the exit code of RunProcess.R. If it is 0 and the computer name is smhb (i.e. production computer) then all data in /data_app/sykdomspuls/*.RDS is uploaded to the folder /data/ on sykdomspulsen.fhi.no (i.e. uploading results to the external webserver). The file 1_delete_website_token.sh is then run, which deletes the file /data/.deleteThisToRestartR on sykdomspulsen.fhi.no, which triggers a script on the external webserver to restart R on the external webserver. After R is restarted, RunAPI.R is automatically run, loading in the new data for the API.
