A full blown web application with Node.js 8
The application stack
Let’s dissect our application. Which parts need to be imple-
mented in order to fulfill the use cases?
• We want to serve web pages, therefore we need an HTTP
server
• Our server will need to answer differently to requests,
depending on which URL the request was asking for, thus
we need some kind of router in order to map requests to
request handlers
• To fullfill the requests that arrived at the server and have
been routed using the router, we need actual request
handlers
• The router probably should also treat any incoming POST
data and give it to the request handlers in a convenient
form, thus we need request data handling
• We not only want to handle requests for URLs, we also
want to display content when these URLs are requested,
which means we need some kind of view logic the request
handlers can use in order to send content to the user’s
browser
• Last but not least, the user will be able to upload images,
so we are going to need some kind of upload handling
which takes care of the details
Let’s think a moment about how we would build this stack with
PHP. It’s not exactly a secret that the typical setup would be an
Apache HTTP server with mod_php5 installed.
Which in turn means that the whole “we need to be able to serve
