webpack-virtual-modules

Webpack plugin that allows you to create virtual (in-memory) modules at compile time. Current stable version 0.6.2. Updated sporadically; last release Nov 2023. Key differentiator: enables injecting custom modules that don't exist on disk, useful for runtime-generated code or mocking, without modifying the filesystem. Supports webpack 4 & 5. Alternatives like virtual-module-webpack-plugin or inline-source-map have different APIs or less maintenance.
