webpack-validator

Validate your webpack configs using joi schema. Provides static type checking, spell checking, and semantic validations (e.g., preventing simultaneous use of loader and loaders). Current stable version is 3.0.1. The package is in maintenance mode: webpack v2+ has built-in validation, so this package only supports webpack v1. Last update in 2017, with no active development. Key differentiator: it catches errors like misspelled loader names or incorrect plugin usage via a schema-based validation.
