Expose a lightning component to salesforce classic

I want to expose a lightning component to salesforce classic.

I know we expose the component using visualforce page (refer this link) but is there a way that we can directly expose it to the salesforce classic UI using some features. What is the lightning component in salesforce?

Answered by alex Duncan

The Lightning Component framework is a UI framework for developing web apps for mobile and desktop devices. It's a modern framework for building single-page applications with dynamic, responsive user interfaces for Lightning Platform apps. It uses JavaScript on the client side and Apex on the server side.


Now move to how to expose a lightning component to salesforce classic?

However,I have not attempted it, because to me it feels like using technology for technology sake, but I have mused about creating a Lightning app page and accessing it from the classic UI. It can be done in an iFrame via a custom web tab, or from a custom URL link button.

However I suspect the experience of such a cobbled approach would make for a crappy user experience without some kind of extreme UI acrobatics. So my own contempt-prior-to-investigation (and limited amount of time to experiment) has prevented me from attempting this to see how it might work.

But hey...feel free to give it a try. If it works and your users like it, write a blog post and tweet about it.

But for me, if I plan to build a custom UI for the classic UI, Visualforce gives me all kinds of tools to do this already. That's how I would do it.

Update: I just tested the web tab option, and it fails due to serving of lightning urls resources with the header: X-FRAME-OPTIONS:SAMEORIGIN. So give the custom button a try, maybe?
