Is it possible to use third-party standard Web Components with Lightning Web Components? I have seen the documentation about third-party libraries. But what about web components? Has anyone tried to integrate those into your own Lightning Web Components?

  • Do you mean using react in LWC? Mar 26, 2019 at 17:58
  • Not React, Web Components. E.g. there's a growing repository of these: webcomponents.org and many more published through npm. And I can't wrap my head around integrating them with LWC. First, they are usually published as ES6 modules, with a lot of dependencies, so I can't import them from Static Resources (or can I?). Mar 26, 2019 at 21:16

It's impossible to use standard web components in LWC nor in Aura. The customElement.defines API to define a native custom element is currently blocked by Locker because of the security implications this API has.

  • That's a pity. But thank you for confirming this. But I imagine we can still build a web component application and place it inside an Aura lightning:container? Mar 27, 2019 at 12:03

    Locker doesn't run in ligthning:container so native web components should work as expected.
