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 Filter API in Pipedream allows for real-time data processing within workflows. It's designed to evaluate data against predefined conditions, enabling workflows to branch or perform specific actions based on those conditions. This API is instrumental in creating efficient, targeted automations that respond dynamically to diverse datasets. Using the Filter API, you can refine streams of data, ensuring that subsequent steps in your Pipedream workflow only execute when the data meets your specified criteria. This cuts down on unnecessary processing and facilitates the creation of more intelligent, context-aware systems.
export default defineComponent({
async run({ steps, $ }) {
let condition = false
if (condition == false) {
$.flow.exit("Ending workflow early because the condition is false")
} else {
$.export("$summary", "Continuing workflow, since condition for ending was not met.")
}
},
})
