HTTP Adapters

Adapters connect Nevr to HTTP frameworks.

What Are Adapters?

Adapters convert HTTP framework requests to Nevr's internal format and vice versa.

Express Request → Adapter → NevrRequest → Core → NevrResponse → Adapter → Express Response

Available Adapters

Adapter	Framework	Best For
toNextHandler	Next.js	Full-stack React apps
expressAdapter	Express.js	REST APIs, traditional Node.js
honoAdapter	Hono	Edge, Cloudflare Workers

Usage

Next.js

// app/api/[...nevr]/route.ts
import { toNextHandler } from "nevr/adapters/nextjs"
import { api } from "@/lib/nevr"

export const { GET, POST, PUT, PATCH, DELETE } = toNextHandler(api)

Express

import express from "express"
import { expressAdapter } from "nevr/adapters/express"
import { api } from "./config"

const app = express()
app.use(express.json())
app.use("/api", expressAdapter(api))
