Js. body to gain access to the items we POST in a request. We then validate the request that returns a 400 Bad Request if it is invalid. post; if we get an error, we return 500 Internal Server Error, and if the project already exists, we return a 409 Conflict response. js.

Json, which returns a 404 status code and the message Not Found. The next parameter is not called as our 404 middleware ends the request by returning a response. exports = app; Logging middleware Express comes with a logger middleware via Connect; it's very useful for debugging an Express application. exports = app; The immediate option will write a log line on request instead of on response. The dev option provides concise output colored by the response status. The logger middleware is placed high in the Express stack in order to log all requests.
If we get an error, we return it; if we cannot find the project, we return null. If we find the project, we delete it and return an empty response. js. We start by defining a route called del. del and passing the id. If we get an error, we return 500 Internal Server Error; if the project does not exist, we return a 404 Not Found. If we find the project, we return a 204 No Content response. js for our feature List projects. This resource will GET all projects from route /project and return a 200 Ok status.
