[Request] AWS Cognito Examples

[hypnoseal]

I am currently exploring using some AWS services in a Rust PoC. Quite a few of the AWS services I'm interested in this SDK have excellent examples on how to use/implement them. However, there is only one example for cognitoidentityprovider. Would it be possible to request additional examples or guidance on implementing cognitoidentityprovider?

For example, some additional examples on the following would be very helpful:

• User creation/sign-up (specifically: admin_create_user)
• User Pool and Group creation/listing/management (specifically: create_group, create_user_pool, delete_group, delete_user_pool, update_group, update_user_pool, list_groups, list_users_in_group, etc.)
• User authentication (specifically: admin_initiate_auth), to add to this the best practices for user auth with Cognito are not necessarily clear and how to properly incorporate SRP with the middleware and frontend is still a bit beyond my understanding with this library.

The general structure of this project is to develop, more-or-less, a Rust based middleware (pretty much Actix, Tera, and a few other crates) that ties together a variety of AWS services to deliver the intended functionality. As such the general structure is:

AWS < - > Rust Middleware/Server < - > Client Frontend

It would be very helpful and drastically reduce development time to have access to more examples for Cognito. The examples for other services, such as DynamoDB, are excellent and provide a great starting point.

Any additional examples, help or guidance would be greatly appreciated.

Thank you

Hey @hypnoseal, thanks for creating this thoughful request. I'm going to connect with our docs writer and let them know about this post. We're currently focusing on features and bugfixes so I don't yet have an estimate of when we'll get to this. Thank you for your patience.

Thank you @Velfi I appreciate it. I still plan on going forward with building the PoC with what is available. So, if there is any way I can contribute to the development of documentation/examples please let me know.

To follow up, another example or strategy that would be super helpful with Cognito is:

• How to implement a WASM payload with cognitoidentityprovider so that we can use sign_up and initiate_auth (with the USER_SRP_AUTH auth flow) for example in the user's browser which then allows for the user to authenticate directly with Cognito (no middleware involved, thus limiting MITMA) and have an appropriate token available for the middleware.

Thanks again for the consideration. I'm very much looking forward to seeing continued progress with this SDK and putting it to work!

We got this on our example writer's backlog.

Thanks for the update, @Velfi! I'm pushing through with the PoC and, in order to do that, must wrap my head around the SDK. Part of this is making some examples for myself of cognitoidentityprovider just to see how it works. Since I've already started that process I've put some simple examples in a public repository which I will continue to update as I add more examples.

The repository can be found here: cognitoidentityprovider-examples

I'm very happy to continue to contribute with these. If you'd like I can create an issue then a pull request with a fork including these examples in the appropriate spot, once the examples are a bit closer to AWS's documentation style. Also, please do pass this along to the example writer; hopefully, it will help speed along their progress and we can support each other in producing some excellent examples for your docs!

I'm outrageously excited to be building some AWS powered Rust apps. Excellent SDK so far!

Thank you

Hi,
I just wanted to let you know that I released a Rust library to authenticate to a cognito user pool using SRP.
https://crates.io/crates/cognito_srp
It is not production ready, I only did manual end-to-end tests but it might be helpful.

If you want to see a comprehensive example using the AWS SDK for Rust see https://github.com/lucdew/cognito-srp-auth

Examples for gust auth would be nice

@akashlama1998-icloud The best place to request this is in the examples repo.
