Tiny ~1Kb JS size
Website performance matters, and our tiny web SDK won't even be noticeable.
What does the code look like?
Step 1: Initiate Authentication from Front End
await
jam
.
initAuth
(
"someone@example.com"
)
;
After this call from your front end javascript, the user will receive an email with a magic link to log in.
Step 2: Receive and Verify the Token
const
email
=
await
jam
.
verify
(
req
.
params
.
idToken
)
;
When the user clicks the link, you get a request that you can verify is a valid user - that's it!
