Deployment of a targets pipeline to RStudio Connect

Setup

You have to set your environment variables in the environment. If you are developing locally you do this by executing:

Sys.setenv("CONNECT_SERVER" = "XXXXX")
Sys.setenv("CONNECT_API_KEY" = "XXXXX")

Then you need to install the renv package and restore the snapshot so that you have all of the packages you need available.

install.packages("renv")
renv::restore()

When you are publishing the pipeline to RStudio Connect, you deploy the content and the necessary environment variables will be in the environment without any human intervention.

Running the pipeline

The driver.Rmd file drives the whole infrastructure build. One you knit that document the pipeline gets built. This file will generate an HTML report that is uploaded to RStudio Connect.

Architecture & Files

• driver.Rmd executes the pipeline and acts as the parent environment
• _targets.R lays down the pipeline and the settings for it
• report/report.Rmd contains the report that will be published to RStudio Connect
• R/connect_helpers.R hosts the function to publish content to RStudio Connect
• config.yml specifies where to store the cache
