Hono deploys, but the app is unreachable

If the build passes and the URL still fails, Hono is either not listening where the platform expects or it crashed while starting.

Check the logs

npx ezhst logs --tail 200

An exception here means the app crashed at boot. A missing variable is a common reason.

Check host and port

Pass port: Number(process.env.PORT) and hostname: "0.0.0.0" to serve from @hono/node-server.

src/index.ts

import { serve } from "@hono/node-server";
import { Hono } from "hono";

const app = new Hono();

app.get("/", (c) => c.text("Hello from EasyHost"));

serve({ fetch: app.fetch, port: Number(process.env.PORT), hostname: "0.0.0.0" });

Check the start command

Hono starts with scripts.start, then main, index.js or server.js.

npx ezhst build show

Known cause for Hono

Bindings from Cloudflare Workers, such as KV or D1, do not exist here. Use process.env, the Postgres database and the S3 bucket.

See the Hono hub for every Hono guide, or free Hono hosting for what is included.
