Browserless is a service that allows you to run headless Chrome instances in the cloud.
The Browserless API on Pipedream allows you to automate browser actions without the overhead of managing your own browser infrastructure. This service provides a way to run Chrome browser sessions programmatically, making it ideal for web scraping, automated testing, and screenshot capture. Leveraging this on Pipedream, you can create serverless workflows that interact with web pages, extract data, and perform actions as a human would, all in a scalable and efficient manner.
import puppeteer from 'puppeteer-core@14.1.0';
export default defineComponent({
props: {
browserless: {
type: "app",
app: "browserless",
}
},
async run({steps, $}) {
// See the browserless docs for more info:
// https://www.browserless.io/docs/
const browser = await puppeteer.connect({
browserWSEndpoint: `wss://chrome.browserless.io?token=${this.browserless.$auth.api_key}`
})
const page = await browser.newPage()
const url = "https://example.com"
const type = "png"
await page.goto(url)
const screenshot = await page.screenshot()
// export the base64-encoded screenshot for use in future steps,
// along with the image type and filename
$.export("screenshot", Buffer.from(screenshot, 'binary').toString('base64'))
$.export("type", type)
$.export("filename",`${url.replace(/[&\/\\#, +()$~%.'":*?<>{}]/g, '_')}-${+new Date()}.${type}`)
await browser.close()
},
})
The Delay API in Pipedream is a built-in function that allows you to pause a workflow for a specified amount of time. This can be incredibly useful when you need to stagger API calls to avoid rate limits, wait for an external process to complete, or simply introduce a delay between actions in a sequence. With precision up to milliseconds, the Delay API provides a simple yet powerful tool for managing timing in automation workflows.
export default defineComponent({
async run({steps, $}) {
// Specify the amount of time to delay your workflow in milliseconds
return $.flow.delay(5000)
},
})
