aws-appsync-community VS draw.io

For context; the web application is built with React and TypeScript which makes calls to an AppSync API that makes use of the Lambda and DynamoDB datasources. We use Step Functions to orchestrate the flow of events for complex processing like purchasing and renewing policies, and we use S3 and SQS to process document workloads.

AWS AppSync I'm keeping this section a bit shorter for you all, since AppSync is not something I have actually used personally, but have heard great things about. AppSync is another API option AWS has made available specifically for applications that want to take advantage of GraphQL or a Publish/Subscribe model. The GraphQL model may be of interest to front end developers that need to query multiple sources of data from one API endpoint, like databases or microservices. The Pub/Sub model I am more familiar with in the IoT hardware-communicates-with-software aspect, however this is also powerful for frontend developers looking to take advantage of real-time updates with serverless WebSocket connections. With AppSync, you also have caching, offline data synchronization, and real-time updates. You can learn more and check out the developer docs on the AWS Website.

Amplify is a set of tools that allows full-stack web and mobile developers to create and build apps. It makes using AWS services, like our Cognito identity and access management service, or our managed GraphQL service AppSync, much simpler and straight forward to use.

This was the top-voted, long-awaited request for AppSync.

Appsync is the AWS service focus on creating flexible APIs, and Amplify is the framework that combines multiple AWS tools to help you build any type of Application.

If you're building an AppSync/GraphQL API for that, yeah, that's a problem, better to use relational like Postegres.

AWS AppSync is a serverless GraphQL and Pub/Sub API service that many developers love. Turing the complex job of creating and managing a GraphQL API with real-time capabilities into a few lines of IaC (or clicks in the console) is a great win for AWS serverless developers.

A: AWS Amplify and AppSync

In the case of microservices/Lambdas required to respond to GraphQL/AppSync, they have to follow the GraphQL contract and provide all data. So they'll often end up making multiple calls, mapping these DTO's to their own VO's that have all the data they need.

At first I thought this was drawio: https://www.drawio.com/ with which you can generate a schema diagram from SQL. Is this the other way around.

For anyone who is willing to use a webapp, I like drawio[0]. You can download locally[1] and self host (I just use the python webserver).

While finding the Github, I see they now actually package an Electron application, so that is probably worth exploring[2].

There are also mockups with more features, so ignore weird UI at first.

Answer:

With such phrasing, for now, I'll consider drawio proprietary with some parts in Apache 2 (even if it's actually the majority of the code).

It might be possible to have a fork with some optional features related to these non provided files removed, if by luck no critical feature is impacted.

Nah, they took the bulk of the renderer behind closed doors a while ago. Behold: https://github.com/jgraph/drawio/blob/dev/src/main/webapp/mx...

Never heard of Backlight Gem, sounds like a flashlight up your ass... Use this, it's free: https://www.drawio.com/

Just wanted to mention this here. You don't need a PC with lots of resources these days. Anything that can run a browser can also be used to edit images, create graphics, or even resumes. I think with those tools, you could even use a crappy library PC as long as it has a modern browser running.
