Installation

npm install fuming

Quick Start

import { connect, collection } from 'fuming';

// Connect to database
const db = await connect('mydb');

// Create a collection
collection.create('users');

// Insert data
await collection.insert('users', {
  name: 'John Doe',
  email: '[email protected]',
  age: 30
});

// Find all documents
const users = collection.find('users');
console.log(users);

API Reference

Connection

connect(dbname: string): Promise<string[]>

Connects to a database. Creates the database directory if it doesn't exist.

const collections = await connect('mydb');
// Returns array of existing collection names

Collections

collection.create(collection: string)

Creates a new collection.

collection.create('users');

collection.find(collection: string)

Retrieves all documents from a collection.

const users = collection.find('users');

collection.insert(collection: string, newData: any)

Inserts a new document into a collection. Automatically generates a unique _id.

await collection.insert('users', {
  name: 'Jane Doe',
  email: '[email protected]'
});

collection.update(collection: string, { key, value }, newData)

Updates a document in a collection based on a key-value pair.

await collection.update('users', 
  { key: 'email', value: '[email protected]' },
  {
    name: 'John Smith',
    email: '[email protected]'
  }
);

collection.remove(collection: string, { key, value })

Removes a document from a collection based on a key-value pair.

await collection.remove('users', {
  key: 'email',
  value: '[email protected]'
});

collection.destroy(collection: string)

Deletes an entire collection.

await collection.destroy('users');

Data Structure

Each document in a collection automatically receives a unique _id field when inserted:

{
  "_id": "lqr1k3j4x9ab2m5n",
  "name": "John Doe",
  "email": "[email protected]"
}

Example Usage

Creating a User Management System

import { connect, collection } from 'fuming';

async function initializeDatabase() {
  // Connect to database
  await connect('userdb');
  
  // Create users collection
  collection.create('users');
}

async function addUser(userData: any) {
  return await collection.insert('users', userData);
}

async function updateUserEmail(oldEmail: string, newData: any) {
  return await collection.update('users', 
    { key: 'email', value: oldEmail },
    newData
  );
}

async function deleteUser(email: string) {
  return await collection.remove('users', {
    key: 'email',
    value: email
  });
}

// Usage
initializeDatabase()
  .then(() => addUser({
    name: 'John Doe',
    email: '[email protected]',
    role: 'admin'
  }))
  .catch(console.error);

Notes

• All collection operations are file-based and synchronous
• Data is stored in JSON format
• Each database is a directory containing JSON files for each collection
• The database name is stored in the environment variables
• Collection names map directly to JSON files
