PureConfig is a Scala library that loads configuration files (HOCON, Java .properties, or JSON via Typesafe Config) into native Scala classes without boilerplate. It derives the deserialization code at compile time, supporting case classes, sealed traits, collections, and optional values out of the box.

Use cases

• load HOCON config into case classes in Scala
• deserialize Typesafe Config to sealed traits
• avoid writing boilerplate config parsing code
• load JSON or .properties files into typed Scala objects
• add custom type support for configuration loading
• validate configuration structure at compile time

When to choose

• you write Scala and use Typesafe Config/HOCON
• you want type-safe, boilerplate-free config loading into case classes
• you need extensible mapping for custom config types

When to avoid

• your project is not on the JVM/Scala
• you need dynamic, schema-less access to configuration
• you use a different config format like YAML or TOML without conversion
