inReplicatedExecution

Check if the code is running in replicated execution mode.

import { inReplicatedExecution, IDL, query, update } from 'azle';

export default class {
    @query([], IDL.Bool)
    isReplicated(): boolean {
        return inReplicatedExecution();
    }

    @update([IDL.Text], IDL.Text)
    conditionalOperation(data: string): string {
        if (inReplicatedExecution()) {
            // This code runs on all replicas
            console.log('Processing in replicated mode');
            return `Replicated: ${data}`;
        } else {
            // This code might run in local testing
            console.log('Processing in non-replicated mode');
            return `Local: ${data}`;
        }
    }
}

The inReplicatedExecution function determines whether the current execution is happening in the Internet Computer's replicated environment or in a local/testing context.

Returns: true if running in replicated execution, false otherwise

Use Cases:

• Conditional logic for production vs. testing
• Debug logging that only runs locally
• Feature flags based on execution context
• Performance optimizations for different environments

Important Notes:

• Returns true when running on the Internet Computer
• Returns false during local development/testing
• Useful for environment-specific behavior
• Helps distinguish between live and test environments
