# How-To – Rezepte { #how-to-recipes }

Hier finden Sie verschiedene Rezepte und „How-To“-Anleitungen zu **verschiedenen Themen**.

Die meisten dieser Ideen sind mehr oder weniger **unabhängig**, und in den meisten Fällen müssen Sie diese nur studieren, wenn sie direkt auf **Ihr Projekt** anwendbar sind.

Wenn etwas für Ihr Projekt interessant und nützlich erscheint, lesen Sie es, andernfalls überspringen Sie es einfach.

```
https://example.com/items/foo
```

...the path would be:

```
/items/foo
```

A "path" is also commonly called an "endpoint" or a "route".

While building an API, the "path" is the main way to separate "concerns" and "resources".
