This is the version that is especially used when you start `deno`. Versions are not necessarily [already installed](/en/docs/web-hosting/languages#versions). ## Environment Your Deno environment starts off empty, with no ready installed libraries. ## HTTP deployment To deploy an HTTP application with Deno, create a *Deno* type site in the **Web > Sites** section. ![](images/deno.png) You need to specify the command that will start your Deno application, for example: ``` deno run --allow-env --allow-net /home/[account]/myapp/index.ts ``` > [!WARNING] > Your application must absolutely listen to IP and the port shown in the site configuration in the *Command* field. The `IP` / `HOST` and `PORT` environment variables can also be used.
