+# Node.js & REST API
+
+[![1-click-deploy](https://defang.io/deploy-with-defang.png)](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-nodejs-rest-api-template%26template_owner%3DDefangSamples)
+
+This is a simple Node.js application that uses Express.js to create a REST API. It has two endpoints: one that returns a status message, and another that fetches and returns average interest rates data from the U.S. Department of the Treasury's Fiscal Data API.
+
+## 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 up --build
+```
+
+## Configuration
+
+For this sample, you will not need to provide [configuration](https://docs.defang.io/docs/concepts/configuration). 
+
+If you wish to provide configuration, see below for an example of setting a configuration for a value named `API_KEY`.
+
+```bash
+defang config set API_KEY
+```
+
+## 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):
