The Robot JavaScript SDK is provided out-of-the box for Studio Community Edition v2020.2 and Enterprise v2020.4 and greater. For Enterprise v2019.10 LTS a stand-alone Add-On installer is also available.
If you upgrade from v2019.10 to v2020.2 and later, you need to manually uninstall the UiPath Robot JS Add-on before running the Studio and Robot installer.
Developer Guide 
To get started, make sure you have community 20.2 or later (or have downloaded the JS Enterprise Add-on). Also, make sure that you have some processes published and available on your local robot and that you can see them from the Agent Desktop (Robot Tray).
This user guide provides samples in JavaScript using ES6 Async-Await patterns and arrow functions. It also assumes that you’re using the provided code from within an async funciton.
Self invoking anonymous async function:
(async () => {
// Your code here...
})()
UiPathRobot.js uses Promises and the npm package provides TypeScript bindings - so this isn’t the only way to use the SDK!
Including the SDK
In order to use the SDK you’ll have to include it on a hosted webpage. You cannot use the SDK from the local filesystem (ie: file:///C:/path/to/index.html), but you can use localhost for development purposes (static server one-liners). There are a few options for including the SDK:
CDN - before the closing of your </ body> tag, include:
<script src="//download.uipath.com/js/1.2.1/UiPathRobot.js"></script>
You should always reference the most recent version of UiPathRobot.js in new projects.
You can find the latest hosted version on robotjs.uipath.com
Alternatively you can download the SDK and host it yourself.
NPM - Compatible with Webpack/Babel
npm install --save @uipath/robot
Then import UiPathRobot:
import {UiPathRobot} from '@uipath/robot';
Process list
Getting the process list is easy, just use .getProcesses(), which will return an array of available processes on your local robot.
const processes = await UiPathRobot.getProcesses()
Now processes is a list of avialalble processes on your local Robot.
Starting a process
To start a processes, you can call .start() on any of the processes returned by the .getProcesses() function. A call to .start() returns a Job Promise. In this example we start the first available process and pass in a single input argument. The key name that you use in this object should correspond to an exact string match for an ‘In’ argument for your process. Keys names that don’t correspond to an argument will be ignored. In this case we’re just using a string as the input value, but for complex arguments types (eg: DataTable) you can use JavaScript objects.
const job = processes[0].start({ SomeKey: "Custom Value" })
Monitor process status
The Job object represents an instance of a process and exposes process status via the onStatus function. This allows you to let users know what the process is doing, while it executes.
Custom Status Messages
When creating your process, use the ‘Report Status’ activity. When that activity executes in your process, the value passed into it will be injected into the callback you provide.
job.onStatus(status => { console.log(`Status: ${status}`) })
Visualize results
After a job is complete you can retrieve all of the process output arguments by name
const results = await job
console.log(results['SomeOutput'], results['AnotherOutput'])
Error handling
If at any time (while getting processes, running a process, etc) there is an error, UiPathRobot.js will throw an exception. To catch this exception you can wrap your code in a try/catch
try{
const processes = await robot.getProcesses()
const sample = processes[0]
const job = sample.start({ NumberToAdd: 6 })
job.onStatus(message => { console.log(`${sample.name}: ${message}`) })
const results = await job
console.log(`Sum: ${results.Sum}`)
} catch(e) {
// If anything goes wrong
console.log(`Exception: ${e}`)
}
Other useful shortcuts
A few other helpful code snippets!
// Get process by ID
const byID = processes.find(p => p.id == "c9973f8d-a46b-41cd-8436-f411cdba3355")
// Get process by Name
const byName = processes.find(p => p.name.includes("MyProcess_env"))
End to end
All together now 
(async () => {
try{
// Get the list of processes
const processes = await UiPathRobot.getProcesses()
// Find a specific process by name
const sample = processes.find(p => p.name.includes("MyProcess_env"))
// Start the process (creates a job)
const job = sample.start({ NumberToAdd: 0 })
// When the job status changes, log it to the console
job.onStatus(status => {console.log(`Status: ${status}`)})
// After the job completes log process results to the console
const results = await job
console.log(results)
} catch(e) {
// Handle any errors
console.error(e)
}
})()
