+# Redis & JavaScript
+[![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-redis-js-template%26template_owner%3DDefangSamples)
+
+This is a Redis and JavaScript application, deployed with Defang. 
+
+Note that Defang supports the use of managed Redis in production deployments. You can enable this feature by adding the `x-defang-redis` tag to your Redis service in the `compose.yaml` file. 
+
+## 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 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.
+
+### `REDISX_URL`
+A Redis connection string of the form `rediss://<username>:<password>@<host>:<port>`. Note that `REDISX` is a prefix which should match of the name of the Redis service (in this case, `redisx`).
+
+```bash
+defang config set REDISX_URL
+```
+
+## 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
+
+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).
