Add a flag query to Netlify Identity links

[erquhart]

This technically isn't an ask for this project, but I'm adding it here for community visibility as it's related to gatsbyjs/gatsby#9565.

Loading the identity widget on every page, especially in an SSG with auto code splitting like Gatsby, often adds unnecessary weight. We should consider adding some sort of flag query to Netlify Identity links so that the widget can be dynamically imported only when necessary. Something like netlify_identity_redirect=true rather than just confirmation_token=xxx, which could technically be from anywhere.

Can we determine if this is feasible or if an alternate approach should be recommended? The PR linked above is an example of what I'd like to help folks avoid, copying internal logic from this repo to determine if the url requires the widget.

who is "we" here? i dont know who would own this

[erquhart]

Netlify platform. We'd need to update various identity links, such as those in verification emails, to use the flag query, and supporting changes would also potentially occur in this repo. Again, raising here instead of internally because it's a community issue.

Any updates on this or anything I can contribute to? Would really want to solve this somehow so all the users don't have to load ~50kb (gzipped) extra JS for something they'll never use 😄

Merged your Gatsby PR as a stop gap 👍

@erquhart would this be solved if we didn't have to include the widget on the home page? e.g. if #171 is addressed, does that solve this problem?

[erquhart]

That would 100% make this request unnecessary 👍
