json-fusion v0.2.3

json-fusion

json-fusion is a Node.js library designed to streamline the process of loading, merging, and reflecting directory hierarchies in JSON files. With json-fusion, you can consolidate information scattered across different JSON files, and reflect your filesystem's structure directly in your data, all with just a few lines of code.

Moreover, json-fusion provides a special handling for index.json files. The contents of index.json files are expanded directly into the parent directory's key, rather than creating a separate index key. This allows more intuitive organization of your JSON files.

Features

• Load all JSON files from a specified directory
• Merge multiple JSON objects into one
• Incorporate the directory hierarchy as keys in the resulting JSON object
• Special handling for index.json files, which are expanded directly under the parent directory's key

Installation

npm install json-fusion

Usage

Here's a basic example of how to use json-fusion:

CommonJS

const jsonFusion = require('json-fusion');

const path = './path/to/your/json/files';
const result = await jsonFusion(path);

console.log(result);

ESModule

import jsonFusion from 'json-fusion';

const path = './path/to/your/json/files';
const result = await jsonFusion(path);

console.log(result);

Structure

Consider the following directory structure:

/path/to/your/json/files
├── config.json
├── users
│   ├── index.json
│   ├── john.json
│   └── jane.json
└── data
    ├── items.json
    └── purchases.json

Running jsonFusion('./path/to/your/json/files') would result in an object similar to:

{
  "config": {/** ./config.json */},
  "users": {
    /** index.json */
    "john": {/** ./users/john.json */},
    "jane": {/** ./users/jane.json */}
  },
  "data": {
    "items": {/** ./data/items.json */},
    "purchases": {/** ./data.purchases.json */}
  }
}

where {/** */} represents the contents of the corresponding JSON file.

API

jsonFusion(path, options)

• path - The path to the directory containing your JSON files.
• options - An optional object containing the following options:
  • exportType - The type of export to use. Defaults to json. Can be one of the following:
    • json - Exports the resulting object as a JSON string.
    • yaml - Exports the resulting object as a YAML string. required yaml package
    • object - Exports the resulting object as a JavaScript object.
  • ignore - An array of file names to ignore. Defaults to ['index.json'].
  • cwd - The current working directory to use. Defaults to process.cwd().
  • export - If you want to export the result to a file, you can set the path to the file to be exported.
  • extensions - An array of file extensions to include. Defaults to ['json'].
    • json - JSON files
    • yaml - YAML files. required yaml package
  • noSpreadIndex - If you want to disable the special handling for index.json files, set this to true. Defaults to false.
