SDK Specifications

Methods and properties

You can include the following methods and properties in your custom application or web page.

Init

The init method is optional. It returns the IRobotSDK instance, which enables you to store it as a variable for later use.

const robot = UiPathRobot.init();

Settings

The settings property of type Settings allows you to change the default port number, the poll interval time in milliseconds, or to disable sending telemetry data.

const robot = UiPathRobot.init();
robot.settings.portNumber = 1234;
robot.settings.pollTimeInterval = 1000;
robot.settings.disableTelemetry = true;

On

The on method is used to attach event handlers to the SDK.

The available SDK events are consent-prompt and missing-components.

consent-prompt

The UiPath JavaScript SDK comes with a built-in consent overlay displayed every time your custom application or web page needs to connect to the Robot.

This consent overlay can be overridden with a custom handler.

const robot = UiPathRobot.init();
robot.on('consent-prompt', consentCode => console.log(consentCode));

missing-components

The missing-components event is raised when the Robot JS Service is not running. In this case, the SDK displays an error, which can be overridden with a custom handler.

const robot = UiPathRobot.init();
robot.on('missing-components', () => console.log('Missing Components'));

Get Processes

The getProcesses method retrieves the list of available processes. Returns a Promise to an array of RobotProcess objects. If the Robot is connected to Orchestrator, it retrieves the processes from the environment and folder the Robot is a part of. Otherwise, local processes are retrieved.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
for(let i=0; i<processes.length; i++){
    console.log(processes[i].name + " (" + processes[i].description + ") - Id=" + processes[i].id);
}

Get Input Arguments Schema

Using the inputArgumentsSchema property of an installed process, you can retrieve the input arguments of a process. Before using the inputArgumentsSchema property, you need to first install the process.

The installProcess method installs a process and returns a Promise to an object of type InstallProcessResult, which contains an array of InputArgumentSchema objects.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const installedProcess = await robot.installProcess(processes[0].id);
for(let i=0; i<installedProcess.inputArgumentsSchema.length; i++){
    console.log("Argument " + i + ":");
    console.log("  name: " + installedProcess.inputArgumentsSchema[i].name)
    console.log("  type: " + installedProcess.inputArgumentsSchema[i].type)
    console.log("  isRequired: " + installedProcess.inputArgumentsSchema[i].isRequired)
    console.log("  hasDefault: " + installedProcess.inputArgumentsSchema[i].hasDefault)
}

Note: In TypeScript, the method install of a RobotProcess object can be used to install a process.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const myProcess = processes.find(p => p.name === "MyProcess");
const installedProcess = await myProcess.install();

Start Job

The startJob method receives an already created Job and starts it. It returns a Promise to an object of type JobResult, which contains the output arguments.

The createJob method creates a robot Job using the Process Id. It can optionally receive the job input arguments. It returns a Job object.

Note: Starting with v2022.10, the process list is refreshed in parallel with the process execution, prior to this, the process list was refreshed before the process started. This means that when running a process for which an update is available, the job might run with the older version of the process.

robot = UiPathRobot.init();
processes = await robot.getProcesses();
const calculatorProcess = processes.find(p => p.name.includes('Calculator'));
const arguments = {
    "input1" : 23,
    "input2" : 42,
    "operation" : "add"
};
const job = robot.createJob(calculatorProcess.id, arguments);
const result = await robot.startJob(job);
console.log(result.Sum);

Note: In TypeScript, a Job can be created by using the Job class constructor.

robot = UiPathRobot.init();
processes = await robot.getProcesses();
const calculatorProcess = processes.find(p => p.name.includes('Calculator'));
const arguments = {
    "input1" : 23,
    "input2" : 42,
    "operation" : "add"
};
const job = new Job(calculatorProcess.id, arguments);
const result = await robot.startJob(job);
console.log(result.Sum);

Job On

The on method of the Job object is used to attach event handlers to the job . The events available are status and workflow-event.

status

The status event is raised during the job execution each time the status of the job has changed.

This event is also raised each time the ReportStatus activity is executed.

const robot = UiPathRobot.init();
const job = robot.createJob('processId');
job.on('status', robotStatus => console.log(robotStatus));
await robot.startJob(job);

workflow-event

The workflow-event event is raised during the job execution each time an activity that sends a workflow event is executed. It is the support for implementing partial results with the help of send interim results activity. The event handler has an argument of type WorkflowEventData.

const robot = UiPathRobot.init();
const job = robot.createJob('processId');
job.on('workflow-event', e => console.log(e.name));
await robot.startJob(job);

Start Process

The method start of the object RobotProcess is used to start a process by passing it input arguments, if available.

It returns an object of type JobPromise.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const myProcess = processes.find(p => p.name === "MyProcess");
const arguments = {
    "a" : 41,
    "b" " 27
};
const result = await myProcess.start(arguments);

Process On Status

The onStatus method is used to attach an event handler to the 'status' event of the Job.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const myProcess = processes.find(p => p.name === "MyProcess");
const result = await myProcess.start().onStatus(status => console.log(status));

Process On Workflow Event

The onWorkflowEvent method is used to attach an event handler to the 'workflow-event' event of the Job.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const myProcess = processes.find(p => p.name === "MyProcess");
const result = await myProcess.start().onWorkflowEvent(e => console.log(e.name));

Stop Process

The stopProcess method is used to stop an executing robot process.

It returns a promise which is resolved on successful cancellation of the running robot process.

const robot = UiPathRobot.init();
const processes = await robot.getProcesses();
const myProcess = processes.find(p => p.name === "MyProcess");
const result = await myProcess.start();
await robot.stopProcess(myProcess);
