ping

A builder function that creates a ping interaction to test connectivity to the Flow Access Node.

The ping interaction is a simple way to test if the Flow Access Node is reachable and responding. This is useful for health checks, connectivity testing, and debugging network issues.

Import

You can import the entire package and access the function:

_10

import * as fcl from '@onflow/fcl';

_10

_10

fcl.ping();

Or import directly the specific function:

_10

import { ping } from '@onflow/fcl';

_10

_10

ping();

Usage

_26

import * as fcl from '@onflow/fcl';

_26

_26

// Simple ping to test connectivity

_26

try {

_26

const response = await fcl.send([fcl.ping()]);

_26

console.log('Access Node is reachable');

_26

} catch (error) {

_26

console.error('Access Node is not reachable:', error);

_26

}

_26

_26

// Use ping for health checks

_26

const healthCheck = async () => {

_26

try {

_26

await fcl.send([fcl.ping()]);

_26

return { status: 'healthy', timestamp: new Date().toISOString() };

_26

} catch (error) {

_26

return {

_26

status: 'unhealthy',

_26

error: error.message,

_26

timestamp: new Date().toISOString(),

_26

};

_26

}

_26

};

_26

_26

const health = await healthCheck();

_26

console.log('Health status:', health);

Returns

_10

export type InteractionBuilderFn = (

_10

ix: Interaction,

_10

) => Interaction | Promise<Interaction>;

A function that processes an interaction object
