json-item-selector v1.1.3

json-item-selector

A package that allow you to create choice logic based on a json file. It helps with choice implementations which depend on an external json file and are heavily nested, mostly for use cases like location selection or game dialog mapping. A basic example below

// ESM
import {JsonItemSelector} from "json-item-selector";
// CommonJS
const {JsonItemSelector} = require("json-item-selector");


const galaxy = {
    // Depth: 0
    "milky-way": {
        // Depth: 1
        "earth": [
            // Depth: 2
            "africa",
            "asia",
            "aurope",
        ],
        // Depth: 1
        "venus": [
            // Depth: 2
            "valnaes",
        ],
    },
    // Depth: 0
    "andromeda": {
        // Depth: 1
        "pegasus":[
          // Depth: 2
          "perg",
          "gaort"
        ],
        // Depth: 1
        "cassopia":[
           // Depth: 2
          'epian',
          'siltron'
        ]
    }
}



const JIS = new JsonItemSelector(galaxy);

console.log(JIS.list(0)); // ["milky-way", "andromeda"] --> List options at 0 depth 

JIS.select("milky-way", 0); // --> Selects from options at 0 depth

console.log(JIS.list(1)); // ["earth", "venus"] --> List options at depth 1

JIS.select("earth", 1); // --> Selects from options at depth 1

console.log(JIS.list(2)); // ["africa", "asia", "europe"]

JIS.select("africa", 2);

console.log(JIS.get_all_selected()); // ["milky-way", "earth", "africa"]
