Quickstart for GitHub Codespaces

Try out GitHub Codespaces in 5 minutes.

GitHub Codespaces está disponible para las organizaciones que usen GitHub Team o GitHub Enterprise Cloud. GitHub Codespaces también está disponible como versión beta limitada para usuarios individuales en los planes GitHub Free y GitHub Pro. Para más información, vea "Productos de GitHub".


In this guide, you'll create a codespace from a template repository and explore some of the essential features available to you within the codespace.

From this quickstart, you'll learn how to create a codespace, connect to a forwarded port to view your running application, use version control in a codespace, and personalize your setup with extensions.

For more information on exactly how GitHub Codespaces works, see the companion guide "Deep dive into GitHub Codespaces."

Creating your codespace

  1. Navigate to the template repository and select Use this template.

  2. Elige un propietario para el repositorio nuevo, escribe el nombre del repositorio, selecciona la configuración de privacidad que prefieras y haz clic en Crear repositorio a partir de plantilla.

  3. En la página principal del repositorio recién creado, haga clic en el botón del Código y selecciona la pestaña Codespaces.

    Si no ves esta opción, entonces los GitHub Codespaces no están disponibles para tu proyecto. Para obtener más información sobre el acceso a los datos GitHub Codespaces, consulta "Crear un codespace".

  4. En la pestaña Codespaces, haz clic en Crear codespace en main.

Running the application

Once your codespace is created, your repository will be automatically cloned into it. Now you can run the application and launch it in a browser.

  1. When the terminal becomes available, enter the command npm run dev. This example uses a Node.js project, and this command runs the script labeled "dev" in the package.json file, which starts up the web application defined in the sample repository.

    npm run dev in terminal

    If you're following along with a different application type, enter the corresponding start command for that project.

  2. When your application starts, the codespace recognizes the port the application is running on and displays a prompt to let you know it has been forwarded.

  3. Click Open in Browser to view your running application in a new tab.

Edit the application and view changes

  1. Switch back to your codespace and open the haikus.json file by double-clicking it in the Explorer.

  2. Edit the text field of the first haiku to personalize the application with your own haiku.

  3. Go back to the running application tab in your browser and refresh to see your changes.

    If you've closed the tab, open the Ports panel and click the Open in browser icon for the running port.

Committing and pushing your changes

Now that you've made a few changes, you can use the integrated terminal or the source view to commit and push the changes back to the remote.

  1. En la barra de actividad, haga clic en la vista Control de código fuente. Vista de control de código fuente

  2. To stage your changes, click + next to the file you've changed, or next to Changes if you've changed multiple files and you want to stage them all.

  3. Type a commit message describing the change you've made.

  4. To commit your staged changes, click the check mark at the top the source control side bar.

    Click the check mark icon

    You can push the changes you've made. This applies those changes to the upstream branch on the remote repository. You might want to do this if you're not yet ready to create a pull request, or if you prefer to create a pull request on GitHub.

  5. At the top of the side bar, click the ellipsis (...).

  6. In the drop-down menu, click Push.

  7. Go back to your new repository on GitHub and view the haikus.json file. Check that the change you made in your codespace has been successfully pushed to the repository.

Personalizing with an extension

Within a codespace, you have access to the Visual Studio Code Marketplace. For this example, you'll install an extension that alters the theme, but you can install any extension that is useful for your workflow.

Note: If you have Settings Sync turned on, any changes you make to your editor setup in the current codespace, such as changing your theme or keyboard bindings, are automatically synced to any other codespaces you open and any instances of Visual Studio Code that are signed into your GitHub account.

  1. In the left sidebar, click the Extensions icon.

  2. In the search bar, enter fairyfloss and install the fairyfloss extension.

    Add an extension

  3. Click Install in Codespaces.

  4. Select the fairyfloss theme by selecting it from the list.
