Baseline's June updates: new features, Vite 7 support, and IDE adoption
June brought several Baseline developments worth noting, from new feature designations to growing tooling support. Here's a summary of what changed over the past month.
Newly available and widely available features
Two features reached Baseline Widely available status in June: small, large, and dynamic viewport units in CSS, and the OES_draw_buffers_indexed WebGL extension.
In related news, a post covering JSON module scripts was published recently, documenting a feature that became Baseline Newly available in late April.
Vite 7.0 sets Baseline Widely available as its default target
The Vite 7.0 release introduces a significant change: the bundler now targets Baseline Widely available by default. This is notable because Baseline Widely available generally reflects features supported across the core browser set for 30 months, making it a reasonable default for many projects.
The choice ultimately depends on the application and its audience. For most developers, Baseline Widely available is a solid benchmark—and Vite now enforces it out of the box. If you're unsure which Baseline tier is right for your project, the guide on choosing a Baseline target offers more detail.
Baseline messaging arrives in browser-based IDEs
Following the earlier announcement that Visual Studio Code would surface Baseline messaging for CSS and HTML features, that capability has now extended to related tools. The web-based version of Visual Studio Code, vscode.dev, now offers the same messaging, as does codesandbox.io, which builds on Visual Studio Code's architecture.
These adoptions reflect a broader trend of Baseline's integration into developer tooling. Expect further expansion into IDEs, linters, and other parts of the development workflow in the coming months.
Coverage and ongoing developments
Outside of tooling, The New Stack published a piece on Baseline, framing it not as prescriptive guidance on which features to use, but as an approach to modernize feature adoption decisions.
If you've spotted a Baseline-related development that wasn't covered here, let the team know and it may appear in a future digest.
