Datanautics

Datanautics is a lightweight key-value storage system with support for nested property access and persistent dumps to disk.

It uses string-based paths (like user[0].profile.name) to get/set deeply nested data, and saves the current state to the dump file for durability.

Features

• Dot/bracket notation access (a.b[0]['call me as u wish'])
• Persistent JSON file storage (auto-saves at configurable intervals)
• Configurable verbosity and custom logger
• Simple API: .get(key), .set(key, value)
• Built on top of property-accessor

Installation

npm install datanautics

Usage

const { Datanautics } = require('datanautics');

const store = new Datanautics({
  dumpPath: './data.json',
  verbose: true,
  logger: console,
});

await store.init();

store.set('users[0].name', 'Alice');
console.log(store.get('users[0].name')); // Output: Alice

Configuration Options

You can pass the following options to the constructor:

| Option | Type | Description | Default | | ---------- | ------------------- | ------------------------------------------------- | ----------------------------------------- | | dumpPath | string, optional | Path to the JSON file for persistent data storage | node_modules/datanautics/data/data.json | | verbose | boolean, optional | Log errors during reading/writing | false | | writer | boolean, optional | master mode if true | true | | logger | object, optional | Custom logger (console, winston, etc.) | console |

store(key: string): Promise<void>

Asynchronously stores data into file defined in options.pathToDumpFile
