What is the best way to create an express web service using Selenium method with JavaScript?

I have been experimenting with a simple method using Selenium and JavaScript. My goal is to execute this method when I invoke a basic web service created with Express. Here is the Selenium method:

async function example()
{
    try{
        let driver = await new Builder().forBrowser("firefox").build();
        await driver.get("https://accounts****.com/login")
        await driver.manage().window().setRect(814, 705)
        await driver.findElement(By.name("email")).sendKeys("*******")
        await driver.findElement(By.name("password")).sendKeys("*****", Key.RETURN)firefox
    }catch(error){
        console.log(">>>error: "+error)
    }
}

I attempted to use this web service, but unfortunately it did not work for me:

server.get('/login', (req, res) => {
  res.send(example())
})

Therefore, my aim is to trigger the Selenium method when I access this web service at http://localhost:3000/login. Any assistance in achieving this would be greatly appreciated!

Answer №1

If you're looking to execute a function through an express call, it's actually quite straightforward.


server.get('/login', (req, res) => {
  res.sendStatus(202) // This status code means the request was Accepted, but might not be handled yet, or might not even succeed.
  example()
})

After informing the client that the request is being processed, we proceed to execute the example function.

It's important to note that the client making the request won't receive any information about what happens next. That's why we respond with 202:Accepted. You can learn more about this status code and its significance here.
