Call a Function - Web SDK

Overview

You can call a Function from a connected client application.

The examples in this section demonstrate calling a simple function named sum that takes two arguments, adds them, and returns the result:

// sum: adds two numbers
exports = function (a, b) {
  return a + b;
};

Usage

In the Node SDK you call Functions as a logged in user with the User.functions interface. There are two ways to call a function:

• You can call a function as if was a method defined locally on the User.functions interface.

• You can call the User.functions.callFunction() method to call a function by providing its stringified name and a list of arguments.

const result = await user.functions.sum(2, 3);

const functionName = "sum";
const args = [2, 3];
const result = await user.callFunction(functionName, ...args);
