Refactoring Login Flow and Handling Errors

[gemanor]

Before attempting this issue, review the code, try the feature, and understand the requirements. Attemptemt requires a detailed design proposal for the refactoring work. There’s no first come, first serve for this bounty; the maintenance team will select the best design proposal.

ATM, the login flow and select environment in Permit is written in a long spaghetti component that needs to be broken into the following pure components:

• Login flow (open browser or validate API key)
• Environment selection
  • Select workspace
  • Select project
  • Select environment
• Store the key to the relevant environment in the keychain

The login flow should be kept as it is today. Start with the login flow and end with storing the API key from the selected environment.

Acceptance criteria:

• Login flow works the same way as it now, but with refactored, clean code
• Possible errors are handled with proper description
• Add e2e test for the flow (use mock for the API calls)

@gemanor Here is my proposal

Hello Gabriel, this is my proposal for https://github.com/permitio/permit-cli/issues/13,

We break the current login.tsx in to 6 components, namely:

• LoginFlow - Handles opening the browser for authentication or validating the API key.
• EnvironmentSelection - Selects the organization, project, and environment.
• SelectWorkspace - Selects the workspace if needed.
• SelectProject - Selects the project.
• SelectEnvironment - Selects the environment.
• StoreKeychain - Stores the key in the keychain.

The new login.tsx component would look something like this:

  return (
    <>
      {state === 'login' && (
        <LoginFlow 
          apiKey={key} 
          onSuccess={handleLoginSuccess} 
          onError={handleLoginError} 
        />
      )}

      {state === 'selectEnvironment' && accessToken && cookie && (
        <EnvironmentSelection 
          accessToken={accessToken} 
          cookie={cookie} 
          workspace={workspace} 
          onComplete={handleEnvironmentSelectionComplete} 
        />
      )}

      {state === 'done' && secret && (
        <>
          <StoreKeychain secret={secret} />
          <Text>Login complete and API key stored!</Text>
        </>
      )}

      {state === 'done' && authError && (
        <Text color="red">{authError}</Text>
      )}
    </>
  );

I also found a bug while working on Windows,

netsh interface ipv4 show excludedportrange protocol=tcp

Protocol tcp Port Exclusion Ranges

Start Port    End Port

     62492       62591
     62592       62691
     62696       62795

* - Administered port exclusions.

We currently use 62419 in browser auth0 authentication (redirection_uri) which leads to this error

⠋ Logging in...
node:events:497
      throw er; // Unhandled 'error' event
      ^

    at Server.setupListenHandle [as _listen2] (node:net:1881:21)

  code: 'EACCES',
  errno: -4092,
  syscall: 'listen',
  address: '::1',
  port: 62419
}

I'll also include a solution in my PR to solve this issue. My proposal is to choose another port, like 62692, for Windows. This will also require you to add this URL to the whitelist in auth0.

I've played around with the code I can ensure a quick turnaround time for this project.
