5.5 Seeing your changes faster
At most, you’ll create a few apps a day, but you’ll run apps hundreds of times, so mastering the development workflow is particularly important. - Hadley Wickham (author)
Avoid clicking the “Run App” button
Use keyboard shortcut:
Cmd/Ctrl + Shift + Enter
Turn auto reload on and run the app in the background as described here.
Gives faster workflow: write some code,
Cmd/Ctrl + S
to save the file and experiment interactively.Disadvantage: harder to debug because the app is running in a separate process.
Bigger apps: interactive testing >> automated testing (Chapter 21).
Demo starting an app as a local job.
