What's the difference between the Builder.isEditing and the Builder.isPreviewing flags?

[neri]

I see in the Docs these 2 flags, but i can’t find any explanation or an API reference of them.

So what does isEditing mean?

What does isPreviewing mean?

And what’s the difference between them?

Enabling on-site previewing and editing in Builder.io - Builder.io

isEditing only applies when the site is loaded inside the editor iframe. isPreviewing applies in this case, as well as when looking at a draft preview outside the editor (i.e. Preview → View current draft).

This works by reading specific search params from the URL, you can see this in the implementation of the Builder class (node_modules/@builder.io/sdk/dist/src/builder.class.js:1656)
