yaml-db

! Important !
Currently, the project is still in development, not all methods have been fully implemented yet and the API is subject to change. If you have a suggestion for improvement or a good idea - you can make a pull-request.

yaml-db is a simple YAML-based database with the ability to run as a service. It allows you to store data in the form of YAML files organized in folders. Each record is represented as a directory with meta.yaml and data.yaml files containing metadata and content.

Installation

To install yaml-db, you can use npm:

npm i -g @ruslankonev/yaml-db

Usage

After installation, you can use the yaml-db command-line interface to start the database server.

yaml-db start

Options

-c, --config [path]: Path to configuration file
-d, --dir [directory]: File storage path (default: ./data)
-p, --port [port]: The port on which the server is raised (default: 5701)

Configuration

You can provide a configuration file in YAML format to customize the database and server settings. The following fields are supported:

server:
  port: 5701 # The port on which the server is raised

database:
  dataPath: ./data # Path to the directory where data is stored

Programmatic Usage

In addition to running yaml-db as a standalone server, you can also use the Database module programmatically in your Node.js projects. This allows you to interact with the database functionality directly within your application code.

Example Usage

To use the Database module in your project, you can require it and create an instance of the database:

const fs = require('fs');
const { Database } = require('yaml-db');

const dataPath = './data/records'; // Change this to the appropriate data path
const db = new Database(dataPath);

// Initialize the database
db.init()
  .then(() => {
    // Create a new record
    const newRecordId = db.createRecord({ title: 'Sample Record' });

    // Upload a file to the record
    const fileBuffer = fs.readFileSync('path/to/your/file.pdf');
    db.uploadFile(newRecordId, fileBuffer, 'file.pdf');

    // Update a record
    db.updateRecord(newRecordId, { title: 'Updated Record Title' });

    // Retrieve record metadata
    const recordMeta = db.getRecordMeta(newRecordId);
    console.log('Record Metadata:', recordMeta);

    // Retrieve record data
    const recordData = db.getRecordData(newRecordId);
    console.log('Record Data:', recordData);
  })
  .catch((error) => {
    console.error('Error:', error.message);
  });

Remember to adjust the dataPath and the paths to your actual files accordingly. This example demonstrates creating records, uploading files, updating records, and searching records by directory.
