Cloudevent SDK for Angular

[shaheer-k]

I want to use standard cloudevent format for sending events from frontend applications to the backend API.

I came to know about the following package which conform to the standard cloudevent format.

https://github.com/cloudevents/sdk-javascript

But I want to use it in angular application. Are there any cloudevent package exists for angular 12.

@shaheer-k there aren't any packages that i know of that wrap this sdk in an angular component(or whatever it is called in Angular land).

But this is just a regular javascript library that should be able to be integrated into any JS framework

@lholmquist
thank you for the response.

I installed cloudevent sdk in Angular 12.0.0 application.
npm install cloudevents

Installation completed successfully.

I tried the following code in my .ts file

import { CloudEvent, CloudEventV1, CloudEventV1Attributes } from "cloudevents";

const ce: CloudEventV1<string> = {
  specversion: "1.0",
  source: "/some/source",
  type: "example",
  id: "1234"
};
const event = new CloudEvent(ce);

The line const event = new CloudEvent(ce); is causing the following error

./node_modules/cloudevents/dist/transport/http/index.js:11:31-46 - Error: Module not found: Error: Can't resolve 'http' in '\node_modules\cloudevents\dist\transport\http'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "http": require.resolve("stream-http") }'
        - install 'stream-http'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "http": false }

./node_modules/cloudevents/dist/transport/http/index.js:12:32-48 - Error: Module not found: Error: Can't resolve 'https' in '\node_modules\cloudevents\dist\transport\http'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.

If you want to include a polyfill, you need to:
        - add a fallback 'resolve.fallback: { "https": require.resolve("https-browserify") }'
        - install 'https-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
        resolve.fallback: { "https": false }

Could you please help me in solving the above error.

@shaheer-k hi - you need to configure webpack to handle the fact that we do not ship polyfills for the https and http modules. The most straightforward way to do this is with the suggestion provided by the error message. Add this to your webpack config.

resolve: {
  fallback: {
    https: false,
    http: false
  }
}

@shaheer-k I am going to close this, assuming you've had some success. If you have not been able to get this to work, please re-open this issue or create a new one. Thanks.
