Codespace Templates

GitHub Codespaces with included free usage is now rolling out to all GitHub Free and Pro accounts. We've added experiences to quickly start new projects in a codespace using many of the frameworks you know and love. These templates are a prebuilt development environment all boxed up to work with one click, without the need to configure your development environment.

Codespace templates come with a pre-configured devcontainer. Using a forwarded port you can see your running web application. The configuration of the devcontainer enables the necessary files to be open by default, run the services necessary, and preview the output of the application in your web editor.

Do you want to start developing in Codespaces, but you're unsure what framework to start with? Use the Blank Template to jump right into a brand new codespace! We've also included a set of starter templates for you on the Codespaces index page. You can even make your own your template for developers to use by creating your own repository template! By creating your own codespace template from a repo template, you can create a one-click, prebuilt development environment for others to use your projects.

We hope you take Codespace Templates out for a spin, and join us in the community discussion space to share your templates and collaborate with us!

Last year, we launched Ruby analysis support in beta for GitHub code scanning. Today, we're announcing the general availability of this feature — covering even more vulnerabilities in Ruby code.

Ruby is part of the top 10 most popular languages on GitHub today. In the past year alone, code scanning (powered by the CodeQL engine) helped Ruby developers resolve more than 4,000 security issues. Set up code scanning on your repositories today and receive actionable security alerts right on your pull-requests.

Since shipping in beta, our Ruby analysis has more than doubled the number of common weaknesses (CWEs) that it can detect. A total of 30 rules check your code for a range of vulnerabilities, including cross-site scripting (XSS), regular expression denial-of-service (ReDoS), SQL injection, and more. Additional library and framework coverage for Ruby-on-Rails ensures that web service developers get even more precise results. We currently support all common Ruby versions, up to and including 3.1. Check out the documentation for more details on compatibility.

Ruby support is available by default in GitHub.com code scanning, the CodeQL CLI, and the CodeQL extension for VS Code. GitHub Enterprise Server (GHES) version 3.4 shipped with Ruby (beta) support, and GHES 3.8 will include this GA release.

Workflows using the ubuntu-latest runner label will soon run on Ubuntu-22.04.

Ubuntu 22.04 became generally available on GitHub-hosted runners in August 2022. Now Ubuntu-22.04 is ready to be the default version for the ubuntu-latest label in GitHub Actions workflows. This change will be rolled out over a period of 8 weeks beginning on October 1, 2022.

If you see any issues with your workflows when they are transitioned to Ubuntu-22.04:

  • File an issue in the runner-images repository
  • Switch back to Ubuntu 20.04 by specifying the ubuntu-20.04 runner label. We will continue to support Ubuntu 20.04.

Note that image software between Ubuntu-20.04 and Ubuntu-22.04 differs by the pre-installed and default versions versions of some tools. See the full list.
