# User Middleware
|
||
|
|
|
||
|
|
- Your middleware is defined in bb user sources.
|
||
|
|
- Middleware is a function in wrap-middleware style.
|
||
|
|
|
||
|
|
# Example
|
||
|
|
|
||
|
|
Middleware should be a function in the form of:
|
||
|
|
|
||
|
|
```clojure
|
||
|
|
(defn my-middleware [handler]
|
||
|
|
(fn [request]
|
||
|
|
;; ...
|
||
|
|
(handler request)
|
||
|
|
;; ...
|
||
|
|
))
|
||
|
|
```
|
||
|
|
|
||
|
|
# Usage
|
||
|
|
|
||
|
|
```shell
|
||
|
|
bb nrepl-server --middleware [my.middleware/println-middleware]
|
||
|
|
```
|
||
|
|
|
||
|
|
--middleware is a vector of fully qualified function symbols.
|
||
|
|
They are required to be located on the babashka classpath.
|
||
|
|
|
||
|
|
This will start babashka with a nrepl server with the middlware defined in `user_middleware/my_middleware/src/my/middleware.clj`.
|
||
|
|
|
||
|
|
You can now connect to the nrepl like usual.
|
||
|
|
|
||
|
|
It is possible to redefine the middleware function from within the running nrepl, because we keep a reference
|
||
|
|
to the sci-var of the middlware.
