I have a Next.js application that calls AWS functions. I want to add a login functionality to it though using a JWT token. I don't know how to do this. I want to publish the app as a static website so I don't want to have an express server.
I have looked at a whole lot of the solutions which all using a server to handle the JWT stuff. I would like to handle all of the authentication in an AWS Lambda function and then send through a JWT token to the Next.js app. Is this possible?
I would suggest you to have a look at AWS Cognito. Cognito User Pool is user directory with signin, signup, lost password, email verification and MFA flows and API. You can also federate identities from other Identity providers, such as Amazon, Google, Facebook, SAML or any OpenID compatible providers.
To make it easier to provision Cognito and use it in your client-side React App, have a look at the Amplify command line tool and SDK.
Adding Cognito to your project is as easy as : amplify add auth && amplify push
Amplify comes with a builtin user interface to implement the signin and signup flows, but of course you can choose to build your own.
The authentication part of Amplify documentation is available at https://aws-amplify.github.io/docs/js/authentication
