Passwordless Auth Core Profiler - Add source param when sending an email

[moon0326]

This PR adds source param to sendEmailLogin function.

This is needed in WPCOM to identify the JPC flow and its product (Jetpack, Woo Payments, and Woo Order Attribution). We use this value to use a different email template for the signup and magic link. I'll open a WPCOM PR soon.

Why are these changes being made?

• To identify JPC flow in WPCOM so we can use a different email template for the sign up and magic link.

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

App Entrypoints (~56 bytes added 📈 [gzipped])

name         parsed_size           gzip_size
entry-login       +153 B  (+0.0%)      +56 B  (+0.0%)

Common code that is always downloaded and parsed every time the app is loaded, no matter which route is used.

Sections (~73 bytes added 📈 [gzipped])

name             parsed_size           gzip_size
jetpack-connect       +245 B  (+0.0%)      +73 B  (+0.0%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

Async-loaded Components (~51 bytes added 📈 [gzipped])

name                      parsed_size           gzip_size
async-load-design-blocks       +153 B  (+0.0%)      +51 B  (+0.0%)

React components that are loaded lazily, when a certain part of UI is displayed for the first time.

Legend

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

Tests well for login and sign up!

One question, it seems the source field also exists on Jetpack Email me a login link flow, but it's empty. Is this expected?

Pre-approving!

I'm only see the send-login-email request made after the second "Send link" button is clicked and the payload has source: "". Is this normal?

I think you might be on a different page.

Where do you see Send link button 🤔 ?

You should see Connect your account first

then Check your email page.

Thanks!

I realized we never worked on Email me a link page as it's not on Figma. We don't have it on the sign up page either. For now, I've disabled it in Disable email me a link from the login page, as it's essentially performs the same function as the main form. I'll check with Veronica to see if we can style the page.
