# Rex Json
> A simple cross-target JSON library for Reason/OCaml
Works with both native and js targets (compiled with bsb-native).
Why would you want this library?
- you want minimal dependencies
- you want forgiving json parsing (comments, trailing commas allowed)
- you're fine with "good enough" performance
## Installation
Add `rex-json` to your `package.json` and your `bsconfig.json`.
## Usage:
```reason
let data = {|
{
"some": "json", // with a comment!
"more": [1,3,],
/* also
multi-line comment */
"this": {
"object": {
"is": {
"really": "nested"
}
}
},
"nested": [{
"and": [1,2,{"stuff": 5}]
}], // trailing commas!
}
|};
let json = Json.parse(data);
let simple = Json.get("some", json); /* == Some(String("json")) */
open Json.Infix;
let stuff = json
|> Json.get("nested")
|?> Json.nth(0)
|?> Json.get("and")
|?> Json.nth(2)
|?> Json.get("stuff")
|?> Json.number; /* == Some(5.) */
/** Using a json path for nested objects */
let nestedString = json
|> Json.getPath("this.object.is.really")
|?> Json.string; /* Some("nested") */
let str = Json.stringify(json); /* back to a string */
Js.log2(stuff, nestedString)
```
