Preconditions is a Node.js library that provides Guava-like precondition error checking, enabling developers to create a fail-fast development environment by immediately throwing errors when invariants fail. It offers multiple interfaces including errr for building error objects, singleton for chainable validations, instance for nested object validation, and constructor for extending the library.
