The old way
- Find a client library
- A good one is golden, however most are outdated or simply unavailable in your app’s programming language.
- Write your own client library
- Takes a lot of effort and must be updated when the API changes. You should be focused on your app, anyway.
- Read API data as dynamic, untyped values
- This is an unpleasant way to program and leaves your app vulnerable to API changes.
With quicktype
- Generate your client libraries
- Given sample API responses, quicktype will generate an easy-to-use client library in your app’s language.
- Spend more time on your app
- quicktype can regenerate types when APIs change, so you can simply update affected app code, if any.
- Access strongly typed API data with help
- Get more out of your editor or IDE (autocomplete, refactoring) when working with typed API data.
