# Tutorial - User Guide

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference.

So you can come back and see exactly what you need.

## Run the code

	// handle each one separately so that they all have the leading "go: " prefix.
	// A plain interface check is not good enough because there might be
	// other kinds of structured errors that are logically one unit and that
	// add other context: only handling the wrapped errors would lose
	// that context.
	if err != nil && reflect.TypeOf(err).String() == "*errors.joinError" {

     * The set chosen is based on a) the name of the configuration that declared this dependency and b) the {@link #confs} mapping for this dependency.
     *
     * The `confs` mapping is structured as `fromConfiguration -> [targetConf...]`. Targets are collected for all configurations in the `fromConfiguration` hierarchy.
     *   - '*' is a wildcard key, that matches _all_ `fromConfiguration values.

`buildSrc` is a Gradle-recognized and protected directory which comes with some benefits:

1. *Reusable Build Logic*:
+
`buildSrc` allows you to organize and centralize your custom build logic, tasks, and plugins in a structured manner.
The code written in buildSrc can be reused across your project, making it easier to maintain and share common build functionality.

2. *Isolation from the Main Build*:
+
