Full stack software development course in the Netherlands

An example makes the layers concrete. Imagine a small feature: members of a sports club book a court for an hour. On the front end there is a form with a date, a time and a court, which must work on a phone at the side of a pitch. It sends a request to the back end, which checks that the member exists, that the court is free and that nobody else booked it a second earlier.

The database holds courts, members and bookings in tables designed so that a double booking cannot be stored even if two requests arrive together.

Around all of that sit the practices: the change lives on its own branch in Git, a test tries to book the same court twice and expects to be refused, and the feature is deployed only when the tests pass. A developer who can build that feature end to end, and explain each decision, is a full stack developer.

Our learners build features like this one many times over, each a little harder than the last, and they are examples, not a specific client project.

A learner does not need every technology in the table. They need one path through every layer, learned well: for example JavaScript and React at the front, Node.js at the back, and one SQL database.

AI coding tools can now write much of the code in each layer. That makes understanding the whole stack more valuable, not less, because someone has to judge whether the generated code fits together and holds up.
