Decode JSON with Functional Decoders

dcode

Note: this library is a work in progress. I'd love for you to try it! If you do find issues, please file an issue. Happy hacking!

This repository lets you decode JSON objects using a functional API. It aims to help you solve these two cases in your everyday programming life:

1. When you don't know the "shape" of the JSON ahead of time
2. When you know there's a huge JSON object coming in, but you only need to get a few values out of it

To accomplish the first case without dcode, you'd usually decode the JSON into a map[string]interface{}, and then deal with the untyped interface{} values as you traverse your way down into the map to get the value you want.

To accomplish the second case without dcode, you'd usually write a struct so that you can decode the values you want, and that's boilerplate code. If the value you want is deeply nested inside the object, this leads to a lot of boilerplate as you build nested structs out.

Interesting? Cool! Check out USAGE.md for details on using this library.

Notes

This library follows patterns from the Elm language JSON decoding library.
