I Built a Server Library for Bun (and got carried away)

I wanted a server library built for Bun, not ported from Node.js. Couldn't find one. So I built it.

What is Verb?

Express-style API, zero dependencies:

import { createServer } from "verb"

const app = createServer()

app.get("/", (req, res) => {
  res.json({ message: "Hello from Verb!" })
})

app.listen(3000)

One API, Many Protocols

HTTP, WebSocket, gRPC, TCP, UDP - same API:

import { server } from "verb"

const http = server.http()
http.get("/api/users", getUsers)

const ws = server.websocket()
ws.on("connection", handleConnection)

const grpc = server.grpc()
grpc.addService(userService, userHandlers)

Zero Dependencies

Verb uses only Bun's built-in APIs. No external packages. Clean node_modules, simple supply chain.

The Ecosystem

Then I needed more stuff. So I built that too:

Hull - Ecto-inspired database toolkit:

const User = schema("users")
  .uuid("id", { primaryKey: true })
  .string("email", 255)
  .timestamps()

const users = await all(repo, whereEq(from(User), "active", true))

Allow - Authentication (JWT, OAuth, local):

const allow = createAllow({
  secret: process.env.JWT_SECRET,
  strategies: [{ name: "local", type: "local", config: {} }]
})

app.get("/dashboard", requireAuth, dashboardHandler)

Hoist - Self-hosted deployment:

hoist deploy

Shelves - S3-compatible object storage you can self-host.

Getting Started

bunx @verb-js/create-verb my-app
cd my-app
bun run dev

Performance

~93k req/sec, ~0.5ms latency. Hybrid router with O(1) static lookups.
