# Javalin Sample
2+
3+
[1-click deploy](https://portal.defang.dev/redirect?url=https%3A%2F%2Fgithub.com%2Fnew%3Ftemplate_name%3Dsample-javalin-template%26template_owner%3DDefangSamples)
4+
5+
This sample demonstrates how to deploy a very basic Javalin sample with Defang. The sample simply outputs "Defang x Javalin" on the webpage.
6+
7+
## Prerequisites
8+
9+
1. Download [Defang CLI](https://github.com/DefangLabs/defang)
10+
2. (Optional) If you are using [Defang BYOC](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html) authenticated with your AWS account
11+
3. (Optional - for local development) [Docker CLI](https://docs.docker.com/engine/install/)
12+
13+
## Deploying
14+
15+
1. Open the terminal and type `defang login`
16+
2. Type `defang compose up` in the CLI.
17+
3. Your app will be running within a few minutes.
18+
19+
## Development
20+
21+
For development, we use a local container. This can be seen in the compose.yaml file. To run the sample locally use the following command:
22+
23+
```bash
24+
docker compose up --build
25+
```
