Advice for Operating a Public-Facing API #Software @JCS
joshua stein has been operating Pushover’s public-facing API for over a decade now and thought to pass on advice for those creating a new API.
Serve your API at api.example.com, never at example.com/api. As your API’s usage grows, it will expand beyond your website/dashboard server and need to move to a separate server or many separate servers. You’ll want to be able to move things around by just pointing its IP somewhere else rather than trying to proxy things from your dashboard server.
Accepting a slightly non-conforming API request today from someone’s ESP8266 buried in a forest might mean you’ll have to keep accepting those same non-conforming requests being made years later, often at the cost of having to implement workarounds in your web framework or server code as it gets upgraded.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
