Where can I find the lwc developer guide?
Initially Lightning Web Components was announced with a blog post. There is also a trailhead project and sample apps. But I don't see anything in the developer documentation portal if I just want to read through the documentation.
The developer guide for lightning web components is located in the component library. There is a public URL for this here:
https://developer.salesforce.com/docs/component-libraryIn addition to the developer guide, new LWC features in the component library also include a new JS playground tool for prototyping LWC code and a resources tab to quickly take you to common resources. There is currently no plan to house the LWC developer guide in the docs portal going forward.
