How it works...

We've set everything up; now, let's see our code working:

> npm run build> node out/middleware.js

We can use some curl requests to test this; let's use GET, POST, and DELETE:

> curl "http://127.0.0.1:8080/some/path/to/get?value=9" Server alive, with Express!> curl -X POST "http://127.0.0.1:8080/a/post/to/a/path" Server alive, with Express!> curl -X DELETE "http://127.0.0.1:8080/try/to/delete?key=22" INTERNAL SERVER ERROR

The logged output will be as follows:

Logger... 2018-05-08T00:22:20.192Z GET /some/path/to/getLogger... 2018-05-08T00:22:44.282Z POST /a/post/to/a/pathLogger... 2018-05-08T00:23:01.888Z DELETE /try/to/deleteError.... DELETEs are not accepted!

Now, we now know how to write our own middleware, but it so happens ...
