Developer experience

Douglas Pereira

The happy path has to be obvious

• Setup in one command, or you already lost people
• Errors should say what to do next
• If seniors still need a wiki to run the app, the app is the problem

Speed is respect

• Slow tests get skipped
• Slow deploys get batched into risk
• Fast feedback is how taste develops

Docs are the product

• README is the front door
• If you answered the question twice, write it down
• Examples beat adjectives

Remove steps

• Every extra flag is a chance to quit
• Defaults should match how people actually work
• The best DX is the one you stop noticing
