Lit Labs
Lit Labs is an umbrella for Lit packages under development that we are actively seeking feedback on. While we encourage real-world use in order to help the feedback process, please note:
- Lit Labs projects are published under the
@lit-labsnpm scope. - Breaking changes are likely to occur more frequently than in non-labs packages, but they will still respect standard semantic versioning guildelines and all changes will be published to the CHANGELOG files.
- While we strive to address all bugs in a timely fashion, bugs in non-labs projects typically receive higher priority than bugs in labs projects.
- When a Lit Labs project is ready to graduate out of labs, we'll begin publishing it under the
@litscope. (For example,@lit-labs/taskgraduated to@lit/task.) Once a package graduates, its first version under the@litscope will match that of the latest in@lit-labs—but only the@litversion will receive subsequent updates. - We may decide to deprecate a Lit Labs project. In such cases, we will notify the community, and a deprecation warning will be added to the npm package. The deprecated package will receive bug fix support for at least 6 months. A record of historical labs packages will be kept on this page.
