Description

A simple React custom hook for pull-to-refresh function that support NextJs SSR.

Purposes

Lots of web application needs custom scroll area for various reasons, however since we are not using browser native scroll, the native pull to refresh API is unusable since it's tied to the scroll event on html tag. This hooks is the solution to resolve this issue by recreating the native pull top behavior while also let you choose what proccess to run on each pull event end.

Prerequisites

This project requires NodeJS (version 16 or later) and React 17+

Getting Started

What's the different to other similar packages?

• react-pull-to-refresh : will run into error 'window' is not defined when using with NextJs SSR.
• react-hooks-pull-to-refresh, react-pull-updown-to-refresh, react-web-pull-to-refresh : Either being unmaintained or doesn't support Typescript, or newer version of React.
• react-native-pull-refresh-android : solution only available for react native.
