library1.5.11jsnpmunverified

Slayer.DB is a lightweight, easy-to-use database module for Node.js offering two backends: JSON-file-based (slayersDBJSON) and MongoDB (slayersDBMongo). Version 1.5.11 supports CRUD operations, nested key access, array manipulation, and table partitioning. It is designed for small-to-medium projects where simplicity is prioritized over scalability, with automatic save cooldowns to prevent corruption. Unlike heavier ORMs, it provides a minimal API with no complex schemas.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

slayersDBMongo

✓ import { slayersDBMongo } from 'slayer.db'

✗ const slayersDBMongo = require('slayer.db').slayersDBMongo

Named export; CommonJS require works with destructuring.

slayersDBJSON

✓ import { slayersDBJSON } from 'slayer.db'

✗ import SlayersDBJSON from 'slayer.db'

Not a default export; must use named import.

default import (entire module)

✓ import * as slayer from 'slayer.db'

✗ import slayer from 'slayer.db'

No default export; use namespace import.

Demonstrates basic CRUD operations with slayersDBJSON: set, get, has, delete, save, and clear.

import { slayersDBJSON } from 'slayer.db'; const db = new slayersDBJSON({ name: 'test' }); db.set('user.name', 'Alice'); db.set('user.age', 30); console.log(db.get('user.name')); // 'Alice' console.log(db.has('user.age')); // true db.delete('user.age'); console.log(db.has('user.age')); // false db.save(); db.clear();

Debug

Known issues

gotchaSaving too frequently can corrupt JSON data. Built-in save cooldown may not prevent all corruption.

fix

Avoid calling save() in rapid loops; rely on internal cooldown or batch updates.

affects: >=1.0.0

gotchaThe slayersDBMongo class requires a running MongoDB instance. No built-in connection pooling or retry logic.

fix

Ensure MongoDB is available and provide correct connection options.

affects: >=1.0.0

gotchafindOneAndUpdate default upsert: true may create documents unintentionally.

fix

Set option { upsert: false } if you do not want automatic document creation.

affects: >=1.0.0
