- I want to use
R to its advantages (data manipulation, modeling, viz, etc.) and then host my work on a website.
- I want to do this without recreating my work in
JS plotting libraries.
Plumber can be used to create REST API endpoints out of R objects/functions to be called from my website.
- This API will be hosted as a single backend service for all of my projects
- It is necessary to programmatically set up
Plumber as a mounted router due to all the different endpoints to manage

Plumber has integrations with DigitalOcean but building a Docker image allows for more flexibility in hosting options- Heroku is free (with caveats) so I have Dockerized the API, hosted it as a Heroku app, & integrated it into my Express app
Travis CI is then set up to automatically re-build the hosted API whenever I push changes to the master branch
