- [Fetch - Basic Usage](https://zaplib.gitbook.io/zaplib2/fetch/fetch.md): Fetch API 的靈感來自 JavaScript，它就像瀏覽器中的 AJAX 功能一樣，提供您方便地進行 HTTP Request 網路存取
- [Fetch - Call API](https://zaplib.gitbook.io/zaplib2/fetch/fetch-get-json-response.md): Fetch 提供簡易的設定，讓串接 API 的工作變得更直覺、更輕鬆
- [Fetch - Customized](https://zaplib.gitbook.io/zaplib2/fetch/custom-fetch.md): Fetch 允許你全權控制並決定該怎麼發送 HTTP Request
- [Fetch - Reference](https://zaplib.gitbook.io/zaplib2/fetch/reference.md): Fetch 可視為進階版的 HttpClient 類別，原先繁複的呼叫都簡化為簡單的高階函數，但也允許自行控制底層物件
