cdk-image-moderation

Event-driven image moderation and notification service with AWS CDK


Sample

This sample create a S3 bucket that will trigger image moderation check on object created and send notification to SNS when specific moderation labels are detected. The SNS2Telegram creates a Lambda function as the SNS topic subscription which fires the notification to a private Telegram chatroom with the image preview and moderation result.

``ts
import { Moderation, SNS2Telegram } from 'cdk-image-moderation';

const app = new cdk.App();
const env = {
region: process.env.CDK_DEFAULT_REGION,
account: process.env.CDK_DEFAULT_ACCOUNT,
};
const stack = new cdk.Stack(app, 'moderation-demo', { env });

// create the moderation
const mod = new Moderation(stack, 'Mod', {
moderationLabels: [
ModerationLabels.EXPLICIT_NUDITY,
ModerationLabels.DRUGS,
ModerationLabels.TOBACCO,
ModerationLabels.ALCOHOL,
ModerationLabels.VIOLENCE,
ModerationLabels.RUDE_GESTURES,
],
});

// send notification via sns to telegram
new SNS2Telegram(stack, 'SNS2TG', {
topic: mod.topic,
chatid: '-547476398',
});
`
