FastComments in React and Next.js

Two packages, and picking the wrong one is the usual first mistake:

• fastcomments-nextjs - use in a Next.js app. Components already declare 'use client', so you can render them straight from a server component with no wrapper.
• fastcomments-react - use in plain React, Vite, CRA, Remix, or anywhere without Next's app router.

Next.js

npm install fastcomments-nextjs

// app/blog/[slug]/page.tsx
import { FastComments } from 'fastcomments-nextjs';
