Usage

Basic Usage

This is a basic example of how to use the client.

const { FreepbxGqlClient, gql } = require("freepbx-graphql-client");

const client = new FreepbxGqlClient("https://freepbx.hostname", {
	client: {
		id: "<client id>",
		secret: "<client secret>",
	}
});

const query = gql`
	query { 
		fetchHostname { 
			hostname
			frameworkVersion
		}
	}
`;
client.request(query).then((result) => console.log(result));

Async/Await Usage

This is an example of how to use the client with async/await.

const { FreepbxGqlClient, gql } = require("freepbx-graphql-client");

async function main() {
	const client = new FreepbxGqlClient("https://freepbx.hostname", {
		client: {
			id: "<client id>",
			secret: "<client secret>",
		},
	});

	const query = gql`
		query { 
			fetchHostname { 
				hostname
				frameworkVersion
			}
		}
	`;
	const result = await client.request(query);
	console.log(JSON.stringify(result, undefined, 2));
}

main().catch((error) => console.error(error));

Using Transaction

FreePBX GraphQL API supports transactions. This is an example of how to use the client with transactions. Once the query is executed, the client waits on the transaction to finish before resolving the promise and continuing.

Note: The status, message, and transaction_id query fields are required when using transactions.

const { FreepbxGqlClient, gql } = require("freepbx-graphql-client");

async function main() {
	const client = new FreepbxGqlClient("https://freepbx.hostname", {
		client: {
			id: "<client id>",
			secret: "<client secret>",
		},
	});

	const query = gql`
		mutation {
			upgradeAllModules(input: {}) {
				status
				message
				transaction_id
			}
		}
	`;
	const result = await client.requestTransactionAndWait(query);
	console.log(JSON.stringify(result, undefined, 2));
}

main().catch((error) => console.error(error));

Using GraphQL Document variables

It is possible to pass variables to the GraphQL document. This format should be used to properly escape any variables to protect the query from GraphQL-injection attacks.

const { FreepbxGqlClient, gql } = require("freepbx-graphql-client");

async function main() {
	const client = new FreepbxGqlClient("https://freepbx.hostname", {
		client: {
			id: "<client id>",
			secret: "<client secret>",
		},
	});

	const query = gql`
		mutation doActivateSystem($deploymentId: String!) {
			activateSystem(input: { deploymentId: $deploymentId }) {
				status
				message
				transaction_id
			}
		}
	`;

	const variables = {
		deploymentId: '123456789',
	};

	const result = await client.requestTransactionAndWait(query);
	console.log(JSON.stringify(result, undefined, 2));
}

main().catch((error) => console.error(error));

ESM/MJS support

This is an example of how to use the client with ESM scripts (aka MJS).

import { FreepbxGqlClient, gql } from 'freepbx-graphql-client'

async function main() {
	const client = new FreepbxGqlClient("https://freepbx.hostname", {
		client: {
			id: "<client id>",
			secret: "<client secret>",
		},
	});

	const query = gql`
		query { 
			fetchHostname { 
				hostname
				frameworkVersion
			}
		}
	`;
	const result = await client.request(query);
	console.log(JSON.stringify(result, undefined, 2));
}

main().catch((error) => console.error(error));
