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.

    Hey Pete, thanks for spreading the good word on this feature. I realize "heck" is quite mild, but please refrain from cursing of any kind while on this site (or Meta) regardless. It is non-content, and both posts and their titles should be limited to only information which is actually relevant to what is being asked. Thanks! Keep up the good work!

  • The developer documentation portal now contains a link to the Lightning Web Components Developer Guide. If you're looking through the list of dev guides at developer.salesforce.com/docs, you will find Lightning Web Components Developer Guide. Commented Jan 22, 2019 at 21:11
  • Thanks for reminding me of this in the question. After reaching out to the docs team about this, they were able to add a stub in the docs portal so that it is reachable from everywhere.

The developer guide for lightning web components is located in the component library. There is a public URL for this here:


In 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.


You no longer need to be logged into a pre-release org to access the component library. The component library public URL now supports direct access to the lightning web component developer guide along with the new playground tool.

!!!!! Spring 19 Pre-Release Note !!!!!

During the pre-release period in order to see the LWC features of the component library, you must access the relative URL from an authenticated org session of a Spring 19 pre-release org. If you go directly to the public URL, you will see the component library of the current GA release, Winter 19:

Simply log into your pre-release org, then append the following onto the host-name of your org:


Once Spring 19 goes GA, in February, the LWC features will become available in all instances when accessing the component library.


The documentation is available on this URL
