The bug with our onboarding library integration was introduced in #8873
because of a change in when `completeOnboarding` was called. We hadn't
realized at the time that the onboarding integration relied upon the
onboarding completing event to know when the onboarding state should
be cleared. Because onboarding is now marked as completed earlier, the
state was cleared just as it was intended to be used.
The onboarding completed event has been moved back to where it was
before: after the user exits the "end of flow" page.
The original problem that #8873 was addressing was a routing issue,
where the user would be redirected back to the seed phrase confirmation
page despite already having confirmed their seed phrase. This was fixed
in a different way here, by updating the routing in the first time flow
switch to skip straight to the end of flow page if the seed phrase has
already been confirmed.
This does involve one user-facing change in behavior; if the user opens
any MetaMask UI before navigating away from the end-of-flow screen,
they will still be considered mid-onboarding so it'll redirect to the
end-of-flow screen. But we do mark onboarding as completed if the user
closes the tab/window while on the end of flow screen, which was
another goal of #8873.
* Add support for one-click onboarding
MetaMask now allows sites to register as onboarding the user, so that
the user is redirected back to the initiating site after onboarding.
This is accomplished through the use of the `metamask-onboarding`
library and the MetaMask forwarder.
At the end of onboarding, a 'snackbar'-stype component will explain to the
user they are about to be moved back to the originating dapp, and it will
show the origin of that dapp. This is intended to help prevent phishing
attempts, as it highlights that a redirect is taking place to an untrusted
third party.
If the onboarding initiator tab is closed when onboarding is finished,
the user is redirected to the onboarding originator as a fallback.
Closes#6161
* Add onboarding button to contract test dapp
The `contract-test` dapp (run with `yarn dapp`, used in e2e tests) now
uses a `Connect` button instead of connecting automatically. This
button also serves as an onboarding button when a MetaMask installation
is not detected.
* Add new static server for test dapp
The `static-server` library we were using for the `contract-test` dapp
didn't allow referencing files outside the server root. This should
have been possible to work around using symlinks, but there was a bug
that resulted in symlinks crashing the server.
Instead it has been replaced with a simple static file server that
will serve paths starting with `node_modules` from the project root.
This will be useful in testing the onboarding library without vendoring
it.
* Add `@metamask/onboarding` and `@metamask/forwarder`
Both libraries used to test onboarding are now included as dev
dependencies, to help with testing. A few convenience scripts
were added to help with this (`yarn forwarder` and `yarn dapp-forwarder`)
