BetterDB Monitor CLI

Monitor and observe your Valkey/Redis databases from the command line.

Installation

Quick Start (npx)

Global Installation

npm install -g @betterdb/monitor

Package Manager

# pnpm
pnpm dlx @betterdb/monitor

# yarn

Usage

First Run

On first run, BetterDB will launch an interactive setup wizard to configure:

• Database connection (host, port, type, credentials)
• Storage backend (SQLite, PostgreSQL, or in-memory)
• Application settings (port, anomaly detection)
• Optional security settings (encryption key, license)

Configuration is saved to ~/.betterdb/config.json.

Commands

# Start the monitor (runs setup if no config exists)
betterdb

# Run the setup wizard
betterdb setup
betterdb --setup

# Skip setup wizard (uses defaults or exits if no config)
betterdb --no-setup

# Show version
betterdb --version

# Show help
betterdb --help

CLI Flags

Override configuration with command-line flags:

betterdb --port 8080           # Custom server port
betterdb --db-host 192.168.1.5 # Custom database host
betterdb --db-port 6380        # Custom database port
betterdb --storage-type memory # Use in-memory storage

Configuration

Configuration is stored at ~/.betterdb/config.json:

{
  "database": {
    "host": "localhost",
    "port": 6379,
    "username": "default",
    "password": "",
    "type": "auto"
  },
  "storage": {
    "type": "sqlite",
    "sqlitePath": "~/.betterdb/data/audit.db"
  },
  "security": {},
  "app": {
    "port": 3001,
    "anomalyDetection": true
  }
}

Storage Options

SQLite (Default)

Requires better-sqlite3 to be installed:

npm install better-sqlite3

PostgreSQL

Provide a connection URL:

{
  "storage": {
    "type": "postgres",
    "postgresUrl": "postgresql://user:password@localhost:5432/betterdb"
  }
}

In-Memory

No persistence, data is lost on restart:

{
  "storage": {
    "type": "memory"
  }
}

Access Points

After starting, the following endpoints are available:

• Web UI: http://localhost:3001
• API: http://localhost:3001/api
• API Docs: http://localhost:3001/api/docs

Requirements

• Node.js >= 20.0.0
• Valkey or Redis instance to monitor
• (Optional) better-sqlite3 for SQLite storage

Security

When an encryption key is configured, database passwords are encrypted at rest using AES-256-GCM envelope encryption. Set the encryption key during setup or via the ENCRYPTION_KEY environment variable.

Publishing (Maintainers)

The CLI is published automatically via GitHub Actions when a version tag is pushed:

# Update version in root package.json and packages/cli/package.json
# Then tag and push
git tag v0.6.0
git push origin v0.6.0

This will:

1. Build the CLI package
2. Publish to npm with provenance
3. Create a GitHub Release with the tarball

Required secrets:

• NPM_TOKEN - npm automation token with publish access

Manual publishing:

pnpm cli:build
cd packages/cli
npm publish --access public
