GitHub Codespaces provides cloud-powered development environments for any activity - whether it's a long-term project, or a short-term task like reviewing a pull request. You can work with these environments from Visual Studio Code or in a browser-based editor.
An environment is the "backend" half of GitHub Codespaces. It's where all of the compute associated with software development happens: compiling, debugging, restoring, etc. When you need to work on a new project, pick up a new task, or review a PR, you can simply spin up a Cloud-hosted environment, and GitHub Codespaces takes care of configuring it correctly. It automatically configures everything you need to work on your project: the source code, runtime, compiler, debugger, editor, custom dotfile configurations, relevant editor extensions and more.
GitHub Codespaces are fully customizable on a per project basis. This is accomplished by including a
devcontainer.json file in the project's repository, similar to VS Code Remote Container development.
Example customizations include:
- Setting which Linux-based operating system to use.
- Automatically installing various tools, runtimes, and frameworks.
- Forwarding commonly used ports.
- Setting environment variables.
- Configuring editor settings and installing preferred extensions.
See the Configuring Codespaces documentation for codespace-specific
Dotfile per user configuration
Dotfiles are files whose filename begins with a dot (.). They typically contain configuration information for applications and can control how terminals, editors, source control, and various other tools behave.
.editorconfig are examples of dotfiles commonly used by developers.
You can specify a GitHub repo containing your dotfiles, a target location for the files, as well as install commands when creating a codespace.
See the Personalizing Codespaces documentation to learn how to add your dotfile configurations to a codespace.
There are getting started topics for both GitHub Codespaces clients. These will fast-track you through signing in to GitHub Codespaces, creating your first codespace, and connecting to it with your preferred client:
- Codespaces in VS Code - Use the GitHub Codespaces extension to connect and work in your environment.
- Codespaces in the browser - Connect to your codespace through a browser-based editor.
The VS Code extension API hides most of the implementation details of running remotely so many extensions will just work in GitHub Codespaces environments without any modification. However, we recommend that you test your extension in a codespace to be sure that all of its functionality works as expected. See the article on Supporting Remote Development and GitHub Codespaces for details.
How do I allow VS Code to access my clipboard for reading?
In certain cases, VS Code might ask you for permission to access the clipboard when reading from it. You should be able to grant access to the clipboard from your browser either through settings (search for "site permissions") or by looking for this option in the address bar on the right:
Once you have granted VS Code access to the clipboard, you can retry the operation.
