Prember Middleware for Ember CLI Development

prember-middleware is an Ember CLI addon designed to facilitate the testing of pre-rendered Ember applications during local development. It provides an `ember-cli` middleware that correctly serves statically pre-rendered HTML files (e.g., `about/index.html` for the `/about` route) from the `dist` directory when running `ember serve`. This is crucial because `ember serve` typically expects dynamic rendering. The package is currently at version 0.1.0, with its last known update around 2017. Given its low version number and explicit Node.js engine constraints (`6.* || >= 7.*`), it is considered abandoned. While the core `prember` addon is actively maintained (last published July 2024, v6.0.0), `prember-middleware` itself has not seen updates. Its primary differentiator is enabling a development environment that mirrors `prember`'s production output without requiring a separate static file server. It integrates directly into the `ember-cli` build pipeline, leveraging Express middleware.
