npm install fastcomments-react-native-sdk --save


This library is a complete webview-free react-native implementation of FastComments.

It supports live commenting, chat, threads, emoticons, notifications, SSO, skins, and full customization by passing in a stylesheet object. All assets can also be customized, and it supports toggling different assets based on dark mode. It only has three direct dependencies (react, hookstate, and a library to render HTML).

It all runs on the FastComments backend, so you only have to incorporate the UI:

    <FastCommentsLiveCommenting config={config} styles={styles} callbacks={callbacks} assets={assets}/>

See example/src for more examples.

Add live chat to your existing React Native application, or even build a social network!

Native WYSIWYG Editor with Image Support!

Native WYSIWYG Editor with Image Support

No WebViews!

This library incorporates its own WYSIWYG editor written in native React, so that we do not depend on loading a WebView to type text.

Configuration Options

This library aims to support all configuration options defined in fastcomments-typescript, just like the web implementation.

FastComments Concepts

The main concepts to be aware of to get started are tenantId and urlId. tenantId is your account identifier. urlId is where comment threads will be tied to. This could be a page URL, or a product id, an article id, etc.

User Notifications

FastComments supports notifications for many scenarios. Notifications are configurable, can be opted-out globally or at a notification/comment level, and supports page-level subscriptions so that users can subscribe to threads of a specific page or article.

For example, it is possible to use Secure SSO to authenticate the user and then periodically poll for unread notifications and push them to the user.

See the example AppNotificationSecureSSO for how to get and translate unread user notifications.

Gif Browser

By default, no image or gif selection is enabled. See example/src/AppCommentingImageSelection.tsx for how to support image and gif uploads. There is a Gif Browser that anonymizes searches and images provided in this library, you simply have to use it.


Please open a ticket with an example to reproduce, including device used, if you identify any performance problems. Performance is a first-class citizen of all FastComments libraries.


Contributions are welcome. Please open a GitHub issue first and tag @winrid to confirm it is not something we are already working on (or not able to accept). Keep in mind that most features should be opt-in by default to maximize flexibility and performance.
