webpack-config

Helps to load, extend, and merge webpack configurations. Current stable version is 7.5.0, released October 2017. Last release was v7.5.0. The package provides a chainable API with `extend()`, `merge()`, and `defaults()` methods supporting environment variables and shareable configs via npm. It is maintained by Fitbit, released under Apache-2.0. Key differentiator: simplifies composing multiple webpack config files with merge semantics and variable interpolation. Be aware: the package has been in maintenance mode since 2017 and may not be actively updated; webpack 2+ compatibility is supported but the API was revamped in v7.0.0.
