Deploy and Host Bun Hono RESTful API 🔥 on Railway

Bun Hono RESTful API 🔥 is a lightweight, production-ready template for building HTTP/JSON APIs using the Bun runtime and the Hono web framework. It compiles your TypeScript server into a single, fast binary, includes basic routing, health checks, and environment-based configuration, and is optimized for container-based deployments such as Railway.

About Hosting Bun Hono RESTful API 🔥

Hosting Bun Hono RESTful API 🔥 on Railway means running a compact, compiled Bun binary inside a minimal container image. The provided Dockerfile handles installing dependencies, compiling src/server.ts into a standalone server binary, and defining the container entrypoint. On Railway, you typically connect your GitHub repository, enable automatic builds from the Dockerfile, and configure environment variables like PORT and NODE_ENV. Railway will then build the image, run the container, and expose your API over HTTPS, taking care of scaling, logs, and restarts for you.

How to Use

After deploying this template, the app is already running on Railway. You can open the generated Railway domain to test the starter app immediately.

If you want to customize the source code, use one of the workflows below.

Via Railway CLI

Use this workflow if you want to edit the project locally and redeploy changes directly from your machine using Railway CLI.

1. Deploy the template.
2. Clone the repository from Source Repo or Upstream Repo in the Railway dashboard.
3. Enter the project directory:

cd 

4. Link your local project directory to the deployed Railway project:

railway link

5. Check the linked project, environment, service, and repository information:

railway status

6. Edit the code locally.
7. Redeploy your local changes to Railway:

railway up

Railway will upload the current local directory and deploy it to the linked service.

Via Git / GitHub

Use this workflow if you want to manage changes through GitHub and let Railway automatically redeploy after every push.

1. Deploy the template.
2. Open Source Repo or Upstream Repo from the Railway dashboard.
3. Fork the repository to your own GitHub account.
4. Clone your fork locally:

git clone 
cd 

5. Edit the code locally.
6. Commit and push your changes to your fork:

git add .
git commit -m "Customize Node.js starter"
git push origin main

7. In Railway, change the service Source Repo to your fork if Railway does not automatically create or link it.
8. After the service is connected to your fork, future pushes to the repository can trigger automatic redeployments.

Common Use Cases

• Building small to medium REST APIs or microservices that need fast cold starts.
• Prototyping backend services for web or mobile apps with minimal infrastructure overhead.
• Hosting health-checked services (/health) and simple user-related endpoints (/users, /users/profile) as part of a larger distributed system.

Dependencies for Bun Hono RESTful API 🔥 Hosting

• Bun runtime & Hono framework – used at build time to compile the TypeScript API into a single binary.
• Docker-compatible container environment – Railway uses your Dockerfile to build and run the compiled server image.

Deployment Dependencies

• Bun documentation: https://bun.sh
• Hono documentation: https://hono.dev
• Railway documentation: https://docs.railway.app

Implementation Details

The template ships with a multi-stage Dockerfile:

FROM oven/bun:1 AS builder
WORKDIR /app
COPY package.json bun.lockb ./
RUN bun install --frozen-lockfile
COPY . ./
RUN bun build src/server.ts --compile --outfile server

FROM debian:bookworm-slim
WORKDIR /app
COPY --from=builder /app/server ./server
CMD ["./server"]

On Railway, this Dockerfile ensures that your service is built into a small, efficient image that starts the compiled ./server binary.
