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.
npm install express-initVerified import paths — ran on the pinned version, not inferred.
Demonstrates defining an Express middleware with an init function and using express-init to initialize all middleware before starting the server.
Ensure your Express version is 4.x.
Consider wrapping initialization in a Promise or using alternative libraries that support async/await.
Ensure that your init function does not rely on being called multiple times.
Always call callback with an error if initialization fails; do not throw.
Ensure your middleware explicitly defines an `init` method if async initialization is needed.
Use `const initialize = require('express-init');` instead of `import initialize from 'express-init';`Add an `init` function to your middleware: `middleware.init = function(app, callback) { ... }`Call `initialize(app, function(err) { ... })` with a valid callback.No dependency data recorded yet.
