JsonR

A BuckleScript lib for handling JSON in Result favor, written in ReasonML.

Usage

Add json-r to your project's dependencies by yarn or npm, And add it to bs-dependencies for bsconfig.json, e.g.

{
    "name": "coolproj",
    "bs-dependencies": [
      "json-r"
    ]
}

Basic example

open JsonR.Json;
open Js_result;

let json = parse_result json_source;

/* Access a field and its value, return a Js_result type */

let title = json |> string_for "title";

/* or more verbose */
let title = json |> member "title" |> to_string;


/* you can also pass key path */
let age = json |> int_for "author.age";

/ * or */
let age = json |> member "author.age" |> to_int;

switch age {
| Ok a => DoWhatYouWant a
| Error e => HeyWeCantParseOutTheAge_CheckTheErrorMessage e
};
