While we don't officially support Shadow DOM, we make a "best effort" to keep the components working in applications that do use Shadow DOM. This may change in the future based on the evolving browser landscape.
Some labels are hopefully obvious, such as "feature" and "a11y". Other issues should all have descriptions on GitHub that outline how they're used. See our labels page for the full descriptions.
Any issue updates will appear on the issue. Due to the large volume of issues and feature requests recieved by the team, we aren't able to regularly comment on all open issues and PRs.
For every pull request, we run a presubmit against Google's internal test suite. This includes tests for all of the projects that use Angular CDK and Angular Material inside Google. As you might imagine, this process can be slow. Once this presubmit passes, PRs can generally be merged quickly. When tests fail, however, the team has to spend time investigating before the PR can be merged. Google uses a single monolithic code repository for its code, which everything at head. Because of this, we cannot merge any PRs that would break an existing project. If a PR has extensive failures, it may be put on the backburner until the team can schedule time to debug the full extent of the issue. If a PR seems ready to merge, but has been inactive, it has very likely encountered some test failures inside Google that must be resovled first.
Like any software team, we have limited time and resources. On top of the work we do in this repo, our team builds and maintains a smaller suite of Google-internal UI components and provides support to product teams inside Google using our components. We do our best to balance our time between bug fixes, support, and new feature work, but ultimately there will always be requests low on the priority queue.
We can generally answer quick or straightforward questions. However, our team doesn't have the resources to provide more hands-on support. We recommend using StackOverflow and Gitter for more help.
Our team is focused on UI components and has decided to be agnostic to how those components are
laid out. We suggest looking at existing layout systems in the front-end ecosystem, as well as
using native CSS Flexbox and CSS Grid. For an Angular-oriented layout library,
angular/flex-layout is a community-maintained project under the Angular umbrella.
What's your relationship to MDC Web?
MDC Web and Angular Material were created independently by two different teams inside Google. The Angular team is now working with the MDC team to share more code to reduce duplication. To that end, we are developing new, API-compatible versions of the Angular Material components backed by MDC Web. See @jelbourn's 2019 ng-conf talk for more details.
