This example is to be used with the Browserless template

Create two reference variables on your Railway service that you deploy your app to -

BROWSER_WEBDRIVER_ENDPOINT=${{Browserless.BROWSER_WEBDRIVER_ENDPOINT}}
BROWSER_TOKEN=${{Browserless.BROWSER_TOKEN}}

Then use process.env.BROWSER_WEBDRIVER_ENDPOINT and process.env.BROWSER_TOKEN in code

Before

constchromeCapabilities=webdriver.Capabilities.chrome();// Set args similar to puppeteer's for best performancechromeCapabilities.set('goog:chromeOptions',{args: ['--window-size=1920,1080','--disable-background-timer-throttling','--disable-backgrounding-occluded-windows','--disable-breakpad','--disable-component-extensions-with-background-pages','--disable-dev-shm-usage','--disable-extensions','--disable-features=TranslateUI,BlinkGenPropertyTrees','--disable-ipc-flooding-protection','--disable-renderer-backgrounding','--enable-features=NetworkService,NetworkServiceInProcess','--force-color-profile=srgb','--hide-scrollbars','--metrics-recording-only','--mute-audio','--headless','--no-sandbox',],});constdriver=newwebdriver.Builder().forBrowser('chrome').withCapabilities(chromeCapabilities).build();

After

constchromeCapabilities=webdriver.Capabilities.chrome();chromeCapabilities.set('browserless:token',process.env.BROWSER_TOKEN);// Set args similar to puppeteer's for best performancechromeCapabilities.set('goog:chromeOptions',{args: ['--window-size=1920,1080','--disable-background-timer-throttling','--disable-backgrounding-occluded-windows','--disable-breakpad','--disable-component-extensions-with-background-pages','--disable-dev-shm-usage','--disable-extensions','--disable-features=TranslateUI,BlinkGenPropertyTrees','--disable-ipc-flooding-protection','--disable-renderer-backgrounding','--enable-features=NetworkService,NetworkServiceInProcess','--force-color-profile=srgb','--hide-scrollbars','--metrics-recording-only','--mute-audio','--headless','--no-sandbox',],});constdriver=newwebdriver.Builder().forBrowser('chrome').withCapabilities(chromeCapabilities).usingServer(process.env.BROWSER_WEBDRIVER_ENDPOINT).build();

The rest of your JS/TS code remains the same with no other changes required.
