# bhvr 🦫

![cover](https://cdn.stevedylan.dev/ipfs/bafybeievx27ar5qfqyqyud7kemnb5n2p4rzt2matogi6qttwkpxonqhra4)

A full-stack TypeScript monorepo starter with shared types, using Bun, Hono, Vite, and React.

## Why bhvr?

While there are plenty of existing app building stacks out there, many of them are either bloated, outdated, or have too much of a vendor lock-in.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.

## Features

- **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 with Turbo for build orchestration

- **Modern Stack**:

  - [Bun](https://bun.sh) as the JavaScript runtime and package manager

  - [Hono](https://hono.dev) as the backend framework

  - [Vite](https://vitejs.dev) for frontend bundling

  - [React](https://react.dev) for the frontend UI

  - [Turbo](https://turbo.build) for monorepo build orchestration and caching

## Project Structure

```

.

├── client/               # React frontend

├── server/               # Hono backend

├── shared/               # Shared TypeScript definitions

│   └── src/types/        # Type definitions used by both client and server

├── package.json          # Root package.json with workspaces

└── turbo.json            # Turbo configuration for build orchestration

```

### Server

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.

```

server

├── bun.lock

├── package.json

├── README.md

├── src

│   └── index.ts

└── tsconfig.json

```

```typescript src/index.ts

import { Hono } from 'hono'

import { cors } from 'hono/cors'

import type { ApiResponse } from 'shared'

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 app

```

If you wanted to add a database to Hono you can do so with a multitude of Typescript libraries like [Supabase](https://supabase.com), or ORMs like [Drizzle](https://orm.drizzle.team/docs/get-started) or [Prisma](https://www.prisma.io/orm)

### Client

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](https://ui.shadcn.com) or routing using [React Router](https://reactrouter.com/start/declarative/installation).

  )

}

export default App

```

### Shared

The 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

├── package.json

├── src

│   ├── index.ts

│   └── types

│       └── index.ts

└── 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

```typescript

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`

```typescript

import { ApiResponse } from 'shared'

```

## Getting Started

### Quick Start

You can start a new bhvr project using the [CLI](https://github.com/stevedylandev/create-bhvr)

```bash

bun create bhvr

```

### Installation

```bash

# Install dependencies for all workspaces

bun install

```

### Development

```bash

# Run all workspaces in development mode with Turbo

bun run dev

# Or run individual workspaces directly

bun run dev:client    # Run the Vite dev server for React

bun run dev:server    # Run the Hono backend

```

### Building

```bash

# Build all workspaces with Turbo

bun run build

# Or build individual workspaces directly

bun run build:client  # Build the React frontend

bun run build:server  # Build the Hono backend

```

### Additional Commands

```bash

# Lint all workspaces

bun run lint

# Type check all workspaces

bun run type-check

# Run tests across all workspaces

bun run test

```

### Deployment

Deplying 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.

## Type Sharing

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:

```typescript

import { ApiResponse } from 'shared/types';

```
