This package contains Express-compatible middleware and helpers for deploying Node.js apps on Fly.io.

Requirements

You should have setup a postgres cluster on Fly. Then:

• ensure that your Postgresql and application regions match up
• ensure that no backup regions are assigned to your application
• attach the Postgres cluster to your application with fly postgres attach

Finally, set the PRIMARY_REGION environment variable in your app fly.toml to match the primary database region.

Installation

yarn add fly-node

Configuration

Insert the request handler middleware as high as possible in the stack, before your controllers, and the error handler after them.

import express from "express"
import { requestHandler, errorHandler } from "@fly/node"

const app = express()

app.use(requestHandler)

app.get("/", function rootHandler(req, res) {
  res.end("Root!");
});

app.use(errorHandler)

TODO

• Mention that Express users with async route handlers will need to wrap them to correctly capture exceptions
