GraphQL Subscriptions at Scale for Real time Monitoring Dashboard

Building a Campaign Data GraphQL API

Create an efficient GraphQL API for campaign monitoring by following these steps:

Creating the Campaign Metrics Schema

Start by defining the structure of your marketing data using the schema below:

Here are some tips for designing your schema:

• Use camelCase for field names (e.g., clickThroughRate).
• Apply PascalCase for type names (e.g., CampaignMetrics).
• Include only the fields you truly need.
• Base your design on how the data will be used.

Once your schema is ready, move on to linking your API with data sources.

Setting Up Data Source Links

Connect your API to marketing platforms by following these key steps:

• Configure Connection Pooling: Set up connection pooling to efficiently manage multiple database requests at the same time.
• Establish Authorization Framework: Use tools like AWS SDK to ensure secure authorization for each data source.
• Implement Error Handling: Build mechanisms to handle failed connections and issues with data retrieval gracefully.

With these connections in place, you can now focus on building query resolvers.

Building Real-Time Query Resolvers

Resolvers should return only the fields requested by users, minimizing data transfer and processing. Use these strategies to optimize performance:

• Use batching techniques to avoid the N+1 query problem.
• Implement resolver-level caching for frequently accessed data.
• Control data demands with tools like pagination.
• Monitor resolver performance using OpenTelemetry.

Here’s an example of how your resolvers might look:

type Campaign {
  id: ID!
  name: String!
  metrics: CampaignMetrics!
  performance: Performance!
}

type CampaignMetrics {
  impressions: Int!
  clicks: Int!
  conversions: Int!
  roi: Float!
}

Setting Up Live Campaign Updates

With your GraphQL API in place, you can integrate live subscriptions to keep tabs on campaign metrics in real-time. This allows for quick adjustments based on performance data.

Understanding GraphQL Subscriptions

Subscriptions create a persistent connection between the client and server, enabling real-time updates. For campaigns, this means you can monitor metrics like impressions, clicks, conversions, and ROI as they happen.

Here’s an example of a subscription query:

subscription CampaignMetricsUpdate {
  onMetricsChange(campaignId: "camp_123") {
    impressions
    clicks
    conversions
    roi
  }
}

You’ll need to define queries that update these metrics as new events occur.

Creating Metric Update Queries

Design your subscription queries to capture key campaign events. For instance:

type Subscription {
  onMetricsChange(campaignId: ID!): CampaignMetrics!
  onConversionEvent(campaignId: ID!): ConversionUpdate!
  onBudgetThreshold(campaignId: ID!, threshold: Float!): BudgetAlert!
}

When setting this up, focus on these important features:

• Timestamp tracking: Keep a record of when updates occur.
• Filtering options: Allow users to focus on specific metrics or campaigns.
• Batch updates: Group multiple updates to improve efficiency.

Configuring the Update Server

Here’s how you can configure your server for live updates:

const server = new ApolloServer({
  schema,
  subscriptions: {
    keepAlive: 30000,
    onConnect: (connectionParams) => {
      if (connectionParams.authToken) {
        return validateToken(connectionParams.authToken);
      }
      throw new Error('Missing auth token');
    }
  }
});

To ensure a secure and efficient setup, consider these measures:

Additionally, use data loaders to reduce database queries, set query depth limits, enable HTTPS for secure connections, and implement strong error handling and monitoring systems. This will help keep your system efficient and secure.

Building the Live Dashboard

Use GraphQL subscriptions to create a dashboard that updates in real-time, displaying campaign metrics dynamically.

Linking the Frontend to GraphQL

To connect your frontend to GraphQL, follow this setup:

import { ApolloClient, split, HttpLink } from '@apollo/client';
import { GraphQLWsLink } from '@apollo/client/link/subscriptions';
import { getMainDefinition } from '@apollo/client/utilities';

const httpLink = new HttpLink({
  uri: 'https://your-api.example/graphql'
});

const wsLink = new GraphQLWsLink({
  uri: 'wss://your-api.example/graphql',
  options: {
    reconnect: true,
    connectionParams: {
      authToken: 'user-token'
    }
  }
});

const splitLink = split(
  ({ query }) => {
    const definition = getMainDefinition(query);
    return (
      definition.kind === 'OperationDefinition' &&
      definition.operation === 'subscription'
    );
  },
  wsLink,
  httpLink
);

Once the connection is established, you can transform raw campaign metrics into visual data for easier analysis.

Adding Data Visualizations

Choose the best chart type for each metric to make the data more understandable:

For implementation, frameworks like Chart.js are a great choice. Here's an example:

import { useSubscription } from '@apollo/client';
import { Line } from 'react-chartjs-2';
import { gql } from '@apollo/client';

const METRICS_SUBSCRIPTION = gql`
  subscription CampaignMetrics($campaignId: ID!) {
    onMetricsChange(campaignId: $campaignId) {
      timestamp
      conversions
      revenue
    }
  }
`;

function CampaignChart({ campaignId }) {
  const { data } = useSubscription(METRICS_SUBSCRIPTION, {
    variables: { campaignId }
  });
  // Chart configuration and data transformation
  return <Line data={/* transformed data */} />;
}

Implementing Live Updates

AWS AppSync handles the real-time updates using WebSocket connections .

function Dashboard() {
  const { data, loading } = useSubscription(METRICS_SUBSCRIPTION, {
    onData: ({ data }) => {
      // Update chart data
      updateChartData(data.onMetricsChange);
    },
    onError: (error) => {
      console.error('Subscription error:', error);
    }
  });

  return (
    // Render the dashboard using the updated data
  );
}

To optimize performance, use GraphQL fragments to limit the data fetched. You can also apply client-side or backend-defined filters with AWS AppSync to ensure only relevant updates are received .

Performance Tips for Live Monitoring

Once you've set up your API and live dashboard, it's crucial to fine-tune performance and security to maintain effective real-time monitoring.

Schema Design Tips

A well-structured GraphQL schema is key to efficient real-time campaign monitoring. Here's how you can structure your schema:

Use SDL descriptions to document your schema, making it easier for your team to collaborate and use the API effectively. For example, include specific fields like dailyConversions, hourlyEngagement, and realtimeRevenue instead of relying on generic data structures. These strategies improve the responsiveness of live queries, which is discussed further below.

Query Performance Methods

To deliver real-time data efficiently, you need to optimize query performance. A well-designed schema sets the stage, but tools like Apollo Client's InMemoryCache can take it further. Here's an example configuration:

const cache = new InMemoryCache({
  typePolicies: {
    CampaignMetrics: {
      fields: {
        conversions: {
          merge: false,
          read(existing) {
            return existing || 0;
          }
        }
      }
    }
  }
});

Selective batching is another powerful tool - it reduces network overhead while ensuring that resource-heavy queries are not delayed.

Data Security Steps

Securing your campaign data is non-negotiable. Use JWT authentication combined with field-level access control to manage who can access what data. Additionally, set query complexity limits to guard against denial-of-service attacks:

const complexityLimit = {
  maxDepth: 3,
  maxCost: 50,
  costPerField: 1
};

Rate limiting is also essential. Here's a simple setup for different operation types:

"GraphQL APIs benefit from the same standard methods you use to reduce the attack surface of any API. In addition, there are GraphQL-specific actions your organization should take to limit your graph's exposure to potential threats." – Apollo GraphQL Docs

For production, disable introspection and use error masking to avoid leaking sensitive implementation details. Persisted queries can also help by ensuring only pre-approved operations can access your campaign data.
