For more information, see Using GitHub Codespaces in Visual Studio Code. Learn how to get started with GitHub Codespaces, then find out more about how a codespace works. If you want to make changes to your codespace that will be more robust over rebuilds and across different codespaces, you have several options. If you work on codespaces in Visual Studio Code, you can enable Auto Save to ensure that your changes are always saved. Save changes to files in the normal way, depending on the editor you are using.
Working in a codespace in the browser
You can edit code, debug, and use Git commands while developing in a codespace with VS Code. Alternatively, you can see any of your codespaces for a specific repository by navigating to that repository, clicking the Code button and selecting the Codespaces tab. The dropdown menu will display all active codespaces for the repository. Using Codespaces in the browser provides you with a fully featured development experience. You can edit code, debug, use Git commands, and run your application. Learn how to develop in a GitHub Codespaces environment, and maintain your data throughout the entire codespace lifecycle.
Folders and files
For more information, see Personalizing GitHub Codespaces for your account. Outside /workspaces, with the exception of the /tmp directory, the directories in a codespace are tied to the lifecycle of the container. This means any changes you make are preserved when you stop and start your codespace, but are not preserved when you rebuild the container. For more information on the /tmp directory, see Persisting environment variables and temporary files. When an application running inside GitHub Codespaces outputs a port to the console, GitHub Codespaces detects the localhost URL pattern and automatically forwards the port. You can click on the URL in the terminal, or the link in the «toast» notification message that pops up at the bottom right corner of VS Code, to open the port in a browser.
After trying out this quickstart you can use Codespaces in other editors, and you can change the default editor. If you already use VS Code, you can use Settings Sync to automatically sync extensions, settings, themes, and keyboard shortcuts between your local instance and any codespaces you create. Because GitHub Codespaces is designed to be ephemeral, you can use it as an isolated environment to experiment, check a teammate’s pull request, or fix merge conflicts. In this example, replace owner/repo with the repository identifier.
verb (used with object)
You can use GitHub CLI to create a new codespace, or start an existing codespace, and then SSH to it. Once connected, you can work on the command line using your preferred command-line tools. Running your application when you first land in your codespace can make for a fast inner dev loop. As you edit, your changes are automatically saved and available on your forwarded port.
When you create a codespace from a template, you can start from a blank template or choose a template suitable for the work you’re doing. Regardless of your local operating system, your codespace will run in a Linux environment. Windows and macOS are not supported operating systems for the remote development container. If you want to use Git hooks in your codespace and apply anything in the git template directory to your codespace, then you must set up hooks during step 4 after the container is created.
- This Primer makes it easy by giving you the templates, videos and step-by-step resources you need to get you started running, testing, debugging and pushing code using this instant cloud developer environment.
- If you create a codespace from an organization-owned repository, use of the codespace will either be charged to the organization (if the organization is configured for this), or to your personal account.
- If you create a codespace from a template, you might start with some initial configuration on top of the default image.
However, it is important to recognize that while avoiding certain circumstances can be beneficial, there are situations where facing challenges head-on is necessary for growth and progress. Thus, understanding when to avoid and when to engage is essential in making balanced, thoughtful decisions. Build all the skills you need to start coding in the cloud in less than an hour. With no installation of software or environment setup required, you can do more with just a few clicks while using the best tools and taking advantage of free benefits for students.

Opening an existing codespace
As a non-root user, you may not automatically have write access to certain directories, but most images allow root access to these directories with the sudo command. You can customize the codespaces that are created for a repository by creating or updating the dev container configuration for the repository. After you change a dev container configuration, you can apply the changes to the current codespace by rebuilding the Docker container for the codespace.
About development with GitHub Codespaces
You can enable Settings Sync to sync extensions and other settings across devices and instances of VS Code. 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. You’ll work in the browser version of Visual Studio how to avoid slippage in trading Code, which is initially the default editor for GitHub Codespaces.
If you want to use Git hooks in your codespace, set up hooks using the devcontainer.json lifecycle scripts, such as postCreateCommand. A shallow clone is then made of your repository, or of the template repository if you’re creating a codespace from a template. This is cloned into the /workspaces directory of the VM and subsequently mounted into the dev container. For more information, see About the directory structure of a codespace below. When you create a codespace, a virtual machine (VM) is created using either the stable or public preview release of the VM host image. For more information, see Choosing the stable or beta host image.
Primer: Codespaces
The host image defines the version of Linux that is used for the VM. Having a dedicated VM ensures that you have the entire set of compute resources from that machine available to you. If necessary, this also allows you to have full root access to your container. The names of user-defined secrets may be displayed on the advanced options page when you create a codespace.
- Outside /workspaces, with the exception of the /tmp directory, the directories in a codespace are tied to the lifecycle of the container.
- You can create a codespace for a branch in a repository to develop online.
- For more information, see About the directory structure of a codespace below.
- Owners of organizations on GitHub Team and GitHub Enterprise plans can pay for their members’ and collaborators’ use of GitHub Codespaces.
Once your codespace is created, the template repository will be automatically cloned into it. Clearing the directories outside /workspaces helps to ensure the rebuilt container is in the same state as it would be in a newly created codespace. When you create a codespace, your repository is cloned into the /workspaces directory in your codespace. This is a persistent directory that is mounted into the container.
GitHub Codespaces is an instant, cloud-based development environment that uses a container to provide you with common languages, tools, and utilities for development. GitHub Codespaces is also configurable, allowing you to create a customized development environment for your project. By configuring a custom development environment for your project, you can have a repeatable codespace configuration for all users of your project. Create, customize and deploy your own portfolio website in minutes. In this template repository we have the development environment and base set and ready to go so that you can immediately launch the Codespace to customize with no setup.
