express-init

Express middleware initialization utility that allows middleware to perform asynchronous setup before the server starts. Version 1.1.2 supports Express 4.x. It calls a user-defined `init` function on each middleware serially before invoking a final callback. Unlike other async setup patterns (e.g., Promises), it uses callbacks and is tightly coupled to Express middleware structure. Maintenance is low; last release was several years ago. Differentiating factor: lightweight, no additional dependencies, and middleware-based initialization pattern.
