A Node.js library for persisting app or module configuration as a JSON file, handling storage location and atomic writes automatically. It supports JSON Schema validation via AJV, dot-notation access, and defaults.

Use cases

• persist user settings for a CLI tool
• store app preferences in a JSON file
• validate config values with a JSON schema
• save and load small key-value config data
• manage nested config options with dot notation

When to choose

• you need simple, small-scale config persistence for a Node.js app or CLI
• you want schema-validated settings with defaults and atomic writes
• you're building an Electron app and want the underlying store behind electron-store

When to avoid

• multiple processes need to write to the same config store concurrently
• you need to persist large datasets (use SQLite or a real database)
• you need a full database with queries or indexing
