Remix JS

Build modern web apps using Remix and built-in browser APIs without relying too much on deprecated dependencies.

About this Repository

This repository serves as a comprehensive guide to building Backend for Frontend (BFF) web applications using Remix, to help create high-performance and maintainable apps. It will cover a wide range of topics, from project setup and routing to data fetching, authentication, and deployment.

Development

From your terminal:

npm run dev

This starts your app in development mode, rebuilding assets on file changes.

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 node applications, the built-in Remix app server is production-ready.

Make sure to deploy the output of remix build

• 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 relevant code/assets from your current app to the new project that's pre-configured for your target server.

Most importantly, this means everything in the app/ directory, but if you've further customized your current application outside of there it may also include:

• Any assets you've added/updated in public/
• Any updated versions of root files such as .eslintrc.js, etc.

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
