Deploy a Fastify App
Fastify is a high-performance, low-overhead web framework for Node.js, designed to deliver an exceptional developer experience.
This guide covers how to deploy a Fastify app on Railway in four ways:
One-Click Deploy From a Template
We highly recommend that you eject from the template after deployment to create a copy of the repo on your GitHub account.
Note: You can also choose from a variety of Fastify app templates created by the community.
Deploy From a GitHub Repo
To deploy a Fastify app on Railway directly from GitHub, follow the steps below:
- Fork the basic fastify GitHub repo.
- If you already have a GitHub repo you want to deploy, you can skip this step.
- Create a New Project.
- Click Deploy from GitHub repo.
- Select the
fastify
repo or your own GitHub repo.- Railway requires a valid GitHub account to be linked. If your Railway account isn't associated with one, you will be prompted to link it.
- Click Deploy Now.
Once the deployment is successful, a Railway service will be created for you. By default, this service will not be publicly accessible.
To set up a publicly accessible URL for the service, navigate to the Networking section in the Settings tab of your new service and click on Generate Domain.
Note: Railway requires that Fastify's .listen
method for the host
be set to ::
. This allows the app to be available over the public and private network.
You can find this in the sample Fastify GitHub repo.
If you don’t set it correctly, you may encounter a 502 error page.
Deploy From the CLI
- Install and authenticate with the CLI.
- Clone the forked fastify GitHub repo and
cd
into the directory.- You can skip this step if you already have an app directory or repo on your machine that you want to deploy.
- Run
railway init
within the app directory to create a new project. - Run
railway up
to deploy.- The CLI will now scan, compress and upload our fastify app files to Railway's backend for deployment.
Use a Dockerfile
- Clone the forked
fastify
repo andcd
into the directory.- You can skip this step if you already have an app directory or repo on your machine that you want to deploy.
- Create a
Dockerfile
in thefastify
or app's root directory. - Add the content below to the
Dockerfile
:# Use the Node.js 18 alpine official image # https://hub.docker.com/_/node FROM node:18-alpine # Create and change to the app directory. WORKDIR /app # Copy local code to the container image. COPY . . # Install project dependencies RUN npm ci # Run the web service on container startup. CMD ["npm", "start"]
- Either deploy via the CLI or from GitHub.
Railway automatically detects the Dockerfile
, and uses it to build and deploy the app.
Note: Railway supports also deployment from public and private Docker images.
