This looks so expensive! I've been going in the same path (with centige.com, WIP) but then I stopped and refactored some stuff: - I had lots of lambdas written in TS. Things were going out of hands. So I refactored them into three lambdas only. A large one that has a switch statement to execute the correct function, and two other ones for some quite long-running processes. - The big lambda was executed too many times. Moving it to an actual server would cost me way less. So I did. Plus I could add more security features that would need AWS API Gateway if I chose to stick with lambdas, which is too expensive. - Initially I used Amplify. And while recently its bundle size has been reduced substantially, it's still big (see https://bundlephobia.com/result?p=aws-amplify@3.0.12 https://bundlephobia.com/result?p=aws-amplify@3.0.12). In my case, I only needed the Auth package, which is 50kb (https://bundlephobia.com/result?p=@aws-amplify/auth@3.2.7 https://bundlephobia.com/result?p=@aws-amplify/auth@3.2.7). However, my options were quite limited and I found myself changing things around to make my app compatible with the way AWS Cognito worked[1] (used by Amplify Auth). I ended up removing it and handling authentication on my own. A better stack for a serverless app would be Vercel for deploying the app (it's cheap, it has SSL, and it has automatic deployments) and either lambdas or a server, depending on your needs, for handling backend stuff. Also, use something like aws4fetch instead of the actual SDK if you can. It will save your visitors some kilobytes :) --- [1]: Email/password auth with Cognito is not the best thing out there. So I wanted to add Google Sign In. At the same time, I wanted to use DynamoDB's row-level access (similar to Firebase's write rules, but more limited). My plan didn't go too well, as I needed the user's Id (provided by Google) when writing to DDB. But Cognito wasn't returning the Id... I spent a couple of days on it, then I figured that I'm just wasting my time.
