middleware injection

[ethicalvats]

Hey very nice article, I have been working as a freelancer developer for over 5 years on small and mid size web apps and was always wondering about the "enterprise patterns" for writing and maintaining code. I have been running my business solo picking on whatever new things come up on the way, be it any new technology or framework. I love the introduction to SOLID and getting to know the awesome InversifyJS.

While I kept your article bookmarked I landed on a client project for which I am willing to use the pattern suggested by you in that article. I have cleared the basics out and the app is running beautifully except I am stuck at a point from where I think you can only take me out.

Issue: I am trying to use an express middleware, multer which is used for multipart form-data parsing and allows to send over both the text fields and image files over the single request. I was able to work with body parser until file upload became a necessity.

I have searched a lot over the internet regarding injecting the middlewares into the controller needless to say I found a lot of approaches but no one is quite compatible to the architecture what you have suggested or may be I am missing out on something.

I would be thankful to you if you can include any example or a code snippet suggesting a way to inject the middleware into the controllers, thanks
