md-notes

An open-source online pastebin for markdown notes that supports password-protected notes. See it in action at md-notes-bay.vercel.app.

Made with TailwindCSS, Prisma, PlanetScale, Next.js, React, Vercel, and TypeScript.

How do I deploy this?

Initialize the database

1. Create a PlanetScale account.
2. Create a database.
3. Copy the connection string.
4. Copy the DATABASE_URL from the .env.example file and paste it into a new .env file.
5. Replace the DATABASE_URL in the .env file with the connection string from step 3.
6. Run npx prisma init to initialize the database.
7. Run npx prisma migrate dev to create the tables from the Prisma schema.
8. Run npm run dev to start the development server.
9. Go to http://localhost:3000 to see the app.

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
   

4. Create a Dockerfile with the following contents:

   Dockerfile

   ########################

   RUN apk add --no-cache libc6-compat openssl
   WORKDIR /app
   
   # Install Prisma Client - remove if not using Prisma
   COPY prisma ./

   COPY package.json yarn.lock* package-lock.json* pnpm-lock.yaml* ./
   RUN \
     if [ -f yarn.lock ]; then yarn --frozen-lockfile; \
     elif [ -f package-lock.json ]; then npm ci; \
     elif [ -f pnpm-lock.yaml ]; then yarn global add pnpm && pnpm i; \
     else echo "Lockfile not found." && exit 1; \
     fi

     elif [ -f package-lock.json ]; then npm run build; \
     elif [ -f pnpm-lock.yaml ]; then yarn global add pnpm && pnpm run build; \

   USER nextjs
   
   EXPOSE 3000
   
   ENV PORT 3000
   
   CMD ["node", "server.js"]

5. 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

6. 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.
