CDK construct that creates a WebSocket endpoint for you for any EventBridge rule you are interested in. (Built for debugging + testing )
Home Page: https://boyney123.github.io/cdk-eventbridge-socket/
Some good comments here about how to build CDK packages.
https://dev.to/aws-builders/correctly-defining-dependencies-in-l3-cdk-constructs-45p
Also I noticed before that https://aws.github.io/jsii/ seems to be a popular way to build CDK constructs.
Here is an example of how it can work? https://github.com/nideveloper/CDK-SPA-Deploy
This is slightly related to #3 and you may want jsii anyway, but there's a more central issue of transitory dependencies as outlined https://dev.to/aws-builders/correctly-defining-dependencies-in-l3-cdk-constructs-45p. Switching to dev & peer dependencies is a good first step to allowing this construct to be more compatible with newer CDK releases.
By default the websocket is open for anyone to connect too.
Think it would be better practice if there was a basic lambda that maybe could verify a token of some sort? Like the example seen here https://docs.aws.amazon.com/apigateway/latest/developerguide/http-api-lambda-authorizer.html
exports.handler = async(event) => {
let response = {
"isAuthorized": false,
"context": {
"stringKey": "value",
"numberKey": 1,
"booleanKey": true,
"arrayKey": ["value1", "value2"],
"mapKey": {"value1": "value2"}
}
};
if (event.headers.authorization === "secretToken") {
response = {
"isAuthorized": true,
"context": {
"stringKey": "value",
"numberKey": 1,
"booleanKey": true,
"arrayKey": ["value1", "value2"],
"mapKey": {"value1": "value2"}
}
};
}
return response;
};Maybe the websocket could send a authorization header, then we could allow the connection if it matches....
Hi,
I have tried using this with latest CDK (version 2.29.0 (build 47d7ec4)) and Node 18.4 and I am always getting this error one way or the other:
/root/cdk-debug-evbridge/node_modules/ts-node/src/index.ts:843
return new TSError(diagnosticText, diagnosticCodes, diagnostics);

Here's my code:
import * as cdk from '@aws-cdk/core';
import { EventBridgeWebSocket } from 'cdk-eventbridge-socket';
export class CdkDebugEvbridgeStack extends cdk.Stack {
constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
super(scope, id, props);
new EventBridgeWebSocket(this, 'CdkDebugEvbridgeSockets', {
bus: 'default',
// This example shows how to listen for all events
eventPattern: {

},
stage: 'dev',
});
// The code that defines your stack goes here

// const queue = new sqs.Queue(this, 'CdkDebugEvbridgeQueue', {

}
