Use the following commands to quickly start a Remix v2 app with a basic Express server:

• CommonJS + server.js: npx create-remix --template https://github.com/xHomu/remix-v2-server/tree/cjs-server.js
• CommonJS + server.ts: npx create-remix --template https://github.com/xHomu/remix-v2-server/tree/cjs-server.ts
• ES Modules + server.js: npx create-remix --template https://github.com/xHomu/remix-v2-server/tree/esm-server.js
• ES Modules + server.ts: npx create-remix --template https://github.com/xHomu/remix-v2-server/tree/esm-server.ts

If updating from a v1 Remix app, the following files probably needs to be adjusted:

• package.json
• remix.config.js
• tsconfig.json
• server.ts or server.js

What changes will depend on whether your repo is ESM/CJS, and whether you're using a typescript or javascript server:

• CommonJS + server.js
• CommonJS + server.ts
• ES Modules + server.js
• ES Modules + server.ts

Development

Start the Remix development asset server and the Express server by running:

npm run dev

This starts your app in development mode, which will purge the server require cache when Remix rebuilds assets so you don't need a process manager restarting the express server.

Deployment

First, build your app for production:

npm run build

Then run the app in production mode:

npm start

Now you'll need to pick a host to deploy it to.

DIY

If you're familiar with deploying express applications you should be right at home just make sure to deploy the output of remix build

• server.js
• build/
• public/build/

Using a Template

When you ran npx create-remix@latest there were a few choices for hosting. You can run that again to create a new project, then copy over your app/ folder to the new project that's pre-configured for your target server.

cd ..
# create a new project, and pick a pre-configured host
npx create-remix@latest
cd my-new-remix-app
# remove the new project's app (not the old one!)
rm -rf app
# copy your app over
cp -R ../my-old-remix-app/app app
