nextjs-flash-message

A Next.js library for sending temporary messages from server functions to the client, displaying them as toast notifications.

This project is a port of sveltekit-flash-message by Andreas Söderlund. Credit goes to the original author for the concept and implementation.

Features

• Send flash messages from server-side functions
• Display messages as toast notifications on the client-side
• Supports success and error message types
• Seamless integration with Next.js applications

Installation

To install nextjs-flash-message, run the following command in your project directory: npm i nextjs-flash-message

Usage

The usage of nextjs-flash-message consists of two main steps:

1. Setting up the FlashMessage component
2. Sending flash messages from server actions

1. Setting up the FlashMessage component

First, you need to add the FlashMessage component to your layout or page where you want the toast notifications to appear. Typically, this would be in your root layout file.

2. Sending flash messages from server actions

In your server actions or server-side functions, you can use the setFlash function to send messages that will be displayed as toast notifications on the client side.

Here's an example of how to use setFlash in a server action:

'use server';
import { setFlash } from 'nextjs-flash-message';

export async function action(prevData: any, formData: FormData) {
    // do something in this actions...
    setFlash({ type: 'success', message: 'Item added successfully!' });
}
