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()
},
})
Develop, run and deploy your Node.js code in Pipedream workflows, using it between no-code steps, with connected accounts, or integrate Data Stores and File Stores.
This includes installing NPM packages, within your code without having to manage a package.json
file or running npm install
.
Below is an example of installing the axios
package in a Pipedream Node.js code step. Pipedream imports the axios
package, performs the API request, and shares the response with subsequent workflow steps:
// To use previous step data, pass the `steps` object to the run() function
export default defineComponent({
async run({ steps, $ }) {
// Return data to use it in future steps
return steps.trigger.event
},
})
