Create T3 App

This is an app bootstrapped according to the init.tips stack, also known as the T3-Stack.

Why are there .js files in here?

As per T3-Axiom #3, we take typesafety as a first class citizen. Unfortunately, not all frameworks and plugins support TypeScript which means some of the configuration files have to be .js files.

We try to emphasize that these files are javascript for a reason, by explicitly declaring its type (cjs or mjs) depending on what's supported by the library it is used by. Also, all the js files in this project are still typechecked using a @ts-check comment at the top.

What's next? How do I make an app with this?

We try to keep this project as simple as possible, so you can start with the most basic configuration and then move on to more advanced configuration.

If you are not familiar with the different technologies used in this project, please refer to the respective docs. If you still are in the wind, please join our Discord and ask for help.

How do I deploy this?

Vercel

We recommend deploying to Vercel. It makes it super easy to deploy NextJs apps.

  • Push your code to a GitHub repository.
  • Go to Vercel and sign up with GitHub.
  • Create a Project and import the repository you pushed your code to.
  • Add your environment variables.
  • Click Deploy
  • Now whenever you push a change to your repository, Vercel will automatically redeploy your website!

Docker

You can also dockerize this stack and deploy a container.

Please note that Next.js requires a different process for buildtime (available in the frontend, prefixed by NEXT_PUBLIC) and runtime environment, server-side only, variables. In this demo we are using two variables, DATABASE_URL (used by the server) and NEXT_PUBLIC_CLIENTVAR (used by the client). Pay attention to their positions in the Dockerfile, command-line arguments, and docker-compose.yml.

  1. In your next.config.mjs, add the standalone output-option to your config:

      export default defineNextConfig({
    reactStrictMode: true,
    swcMinify: true,
+   output: "standalone",
  });

  2. Remove the env-import from next.config.mjs:

    - import { env } from "./src/env/server.mjs";

  3. Create a .dockerignore file with the following contents:

    .dockerignore 
    .env
Dockerfile
.dockerignore
node_modules
npm-debug.log
README.md
.next
.git

  1. Create a Dockerfile with the following contents:

USER nextjs

EXPOSE 3000

ENV PORT 3000

CMD ["node", "server.js"]

  1. To build and run this image locally, run:

    docker build -t ct3a -e NEXT_PUBLIC_CLIENTVAR=clientvar .
docker run -p 3000:3000 -e DATABASE_URL="database_url_goes_here" ct3a

  2. You can also use a PaaS such as Railway's automated Dockerfile deployments to deploy your app.

Docker Compose

You can also use docker compose to build the image and run the container.

  1. Follow steps 1-4 above

  2. Create a docker-compose.yml file with the following:

    docker-compose.yml 
    version: "3.9"
services:
  app:
    platform: "linux/amd64"
    build:
      context: .
      dockerfile: Dockerfile
      args:
        NEXT_PUBLIC_CLIENTVAR: "clientvar"
    working_dir: /app
    ports:
      - "3000:3000"
    image: t3-app
    environment:
      - DATABASE_URL=database_url_goes_here

  3. Run this using docker compose up.
