Overview

Browserless.io strategy to request websites.

Provide the WebSocket URL and your API token via environment variables:

  • BROWSERLESS_IO_WEBSOCKET_URL

  • BROWSERLESS_IO_API_TOKEN

To use this strategy, you need to have a Browserless.io account or run a local Browserless.io instance.

To run a local Browserless.io instance, you can use the following Docker command:

“‘sh docker run \

--rm \
-p 3000:3000 \
-e "CONCURRENT=10" \
-e "TOKEN=6R0W53R135510" \
ghcr.io/browserless/chromium

“‘

When running locally, you can skip setting the environment variables, as above commands are aligned with the default values.
