Add the skeleton of the web application It does nothing more than to server a single page that does nothing interesting. This time i do not use a router. Instead, i am trying out a technique i have seen in an article[0] that i have tried in other, smaller, projects and seems to work surprisingly well: it just “cuts off” the URI path by path, passing the request from handler to handler until it finds its way to a handler that actually serves the request. That helps to loosen the coupling between the application and lower handlers, and makes dependencies explicit, because i need to pass the locale, company, etc. down instead of storing them in contexts. Let’s see if i do not regret it on a later date. I also made a lot more packages that in Numerus. In Numerus i actually only have the single pkg package, and it works, kind of, but i notice how i name my methods to avoid clashing instead of using packages for that. That is, instead of pkg.NewApp i now have app.New. Initially i thought that Locale should be inside app, but then there was a circular dependency between app and template. That is why i created a separate package, but now i am wondering if template should be inside app too, but then i would have app.MustRenderTemplate instead of template.MustRender. The CSS is the most bare-bones file i could write because i am focusing in markup right now; Oriol will fill in the file once the application is working.

Convert the login variables to a struct with parsing and validation It is a lot of code having to check the login variables inside the POST handler, and i could not mark each input field individually as invalid because the generic errors array i was using did no identify which field had the error. Thus, i use more or less the same technique as with Numerus: a struct with the value and the error message. This time the input field does not have the label and extra attributes because i believe this belongs to the template: if i want do reuse the same form template, i should create a common template rather than defining everything in Go. The name is a bit different, however, because it has meaning both to the front and back ends, as it needs to be exactly the same. Writing it twice is error-prone, as with a rename i could easily forget to change one or the other, and here i see value in having that in Go, because it is also used in code.

Handle the login form I now actually handle the /login URL and check whether the email and password are valid, creating the session cookie if correct, but doing nothing else with that cookie, for now. The validation is done by hand for now, because i do not yet how i will actually do it without so much duplication.
