Build Status

  • 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.

API Configuration

  • 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

Hosting

  • 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
