+# Node.js & React & PostgreSQL
+
+[![1-click-deploy](https://raw.githubusercontent.com/DefangLabs/defang-assets/main/Logos/Buttons/SVG/deploy-with-defang.svg)](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-nodejs-react-postgres-template%26template_owner%3DDefangSamples)`
+
+This sample project demonstrates how to deploy a full-stack application using React for the frontend, Node.js for the backend, and PostgreSQL for the database. 
+
+In this sample, we have set up the essential files you need to deploy in production using [Neon](https://neon.tech/) to host your database. We use a connection string to connect Neon to your code. By replacing the pre-configured connection string at .env and at the compose file to yours, you will be ready to deploy this sample with Neon.
+
+## Prerequisites
+
+1. Download [Defang CLI](https://github.com/DefangLabs/defang)
+2. (Optional) If you are using [Defang BYOC](https://docs.defang.io/docs/concepts/defang-byoc) authenticate with your cloud provider account
+3. (Optional for local development) [Docker CLI](https://docs.docker.com/engine/install/)
+
+## Development
+
+To run the application locally, you can use the following command:
+
+```bash
+docker compose -f compose.dev.yaml up --build
+```
+Or run without using Docker by doing the following:
+
+1. run `npm install` to install the nodejs dependencies in both the `client` directory and the `server` directory
+2. create or modify the .env file in both the `client` directory and the `server` directory with localhost, or create a .env.local to override the .env file.
+3. run `npm start`
+
+## Configuration
+For this sample, you will need to provide the following [configuration](https://docs.defang.io/docs/concepts/configuration): 
+
+> Note that if you are using the 1-click deploy option, you can set these values as secrets in your GitHub repository and the action will automatically deploy them for you.
+
+### `DATABASE_URL`
+A connection to the database, which should be in the format of `postgres://username:password@host:port/dbname`.
+```bash
+defang config set DATABASE_URL
+```
+
+### `REACT_APP_API_URL`
+A URL for the React App. For this, you will need to update the `compose.yaml` file to replace `<YOUR_USERNAME>` with your username, which you can get by running `defang whoami`.
+
+## Deployment
+
+> [!NOTE]
+> Download [Defang CLI](https://github.com/DefangLabs/defang)
+
+### Defang Playground
+
+Deploy your application to the Defang Playground by opening up your terminal and typing:
+```bash
+defang compose up
+```
+
+### BYOC (AWS)
+
+If you want to deploy to your own cloud account, you can [use Defang BYOC](https://docs.defang.io/docs/tutorials/deploy-to-your-cloud):

+# Getting Started with Create React App
+
+This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
+
+## Available Scripts
+
+In the project directory, you can run:
+
+### `npm start`
+
+Runs the app in the development mode.\
+Open [http://localhost:3000](http://localhost:3000) to view it in your browser.
+
+The page will reload when you make changes.\
+You may also see any lint errors in the console.
+
+### `npm test`
+
+Launches the test runner in the interactive watch mode.\
+See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
+
+### `npm run build`
+
+Builds the app for production to the `build` folder.\
+It correctly bundles React in production mode and optimizes the build for the best performance.
+
+The build is minified and the filenames include the hashes.\
+Your app is ready to be deployed!
+
+See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+
+### `npm run eject`
+
+**Note: this is a one-way operation. Once you `eject`, you can't go back!**
+
+If you aren't satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+
+Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.
+
+You don't have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
+
