A full-stack TypeScript monorepo starter with shared types, using Bun, Hono, Vite, and React
While there are plenty of existing app building stacks out there, many of them are either bloated, outdated, or have too much of a vendor lock-in. bhvr is built with the opinion that you should be able to deploy your client or server in any environment while also keeping type safety.
- Full-Stack TypeScript: End-to-end type safety between client and server
- Shared Types: Common type definitions shared between client and server
- Monorepo Structure: Organized as a workspaces-based monorepo
- Modern Stack:

bhvr uses Hono as a backend API for its simplicity and massive ecosystem of plugins. If you have ever used Express then it might feel familiar. Declaring routes and returning data is easy.

import { Hono } from 'hono'

import type { ApiResponse } from 'shared/dist'
const app = new Hono()
app.use(cors())
app.get('/', (c) => {
return c.text('Hello Hono!')
})
app.get('/hello', async (c) => {
const data: ApiResponse = {
message: "Hello BHVR!",
success: true
}
return c.json(data, { status: 200 })
})
export default appIf you wanted to add a database to Hono you can do so with a multitude of Typescript libraries like Supabase, or ORMs like Drizzle or Prisma
bhvr uses Vite + React Typescript template, which means you can build your frontend just as you would with any other React app. This makes it flexible to add UI components like shadcn/ui or routing using React Router.

export default AppThe Shared package is used for anything you want to share between the Server and Client. This could be types or libraries that you use in both environments.
shared

└── tsconfig.json
Inside the src/index.ts we export any of our code from the folders so it's usable in other parts of the monorepo
export * from "./types"By running bun run dev or bun run build it will compile and export the packages from shared so it can be used in either client or server
import { ApiResponse } from 'shared'You can start a new bhvr project using the CLI
bun create bhvr# Install dependencies for all workspaces
bun install# Run shared types in watch mode, server, and client all at once
bun run dev
# Or run individual parts
bun run dev:shared # Watch and compile shared types
bun run dev:server # Run the Hono backend
bun run dev:client # Run the Vite dev server for React# Build everything
bun run build
# Or build individual parts
bun run build:shared # Build the shared types package
bun run build:client # Build the React frontendDeplying each piece is very versatile and can be done numerous ways, and exploration into automating these will happen at a later date. Here are some references in the meantime.
Client
Server
Types are automatically shared between the client and server thanks to the shared package and TypeScript path aliases. You can import them in your code using:
import { ApiResponse } from 'shared/types';
