@replayio/node

CLI tool for creating recordings using the Replay version of node.

Overview

The replay version of node is a replacement for the node executable which saves a recording of its behavior to disk that can be uploaded to the record/replay web service for viewing. replay-node is a CLI tool that allows the replay version of node to be selectively used when running node scripts.

Installation

npm i @replayio/node --global

Usage

replay-node can be used in the following ways to create recordings. Afterwards, use the @replayio/replay CLI tool to manage and upload the recordings.

replay-node script.js ...args

Use the replay version of node to record a specific script and arguments.

replay-node --exec executable ...args

Run an executable command with $PATH updated so that all node scripts will use the Replay version of node to record their behavior.

replay-node --update

Ensure the replay version of node is downloaded/updated.

Supported environment variables:

  • RECORD_REPLAY_DIRECTORY (defaults to $HOME/.replay)
  • RECORD_REPLAY_NODE_DIRECTORY (defaults to $RECORD_REPLAY_DIRECTORY/node) Allows to specify a folder in which the replay-patched node binary is to be found.
  • RECORD_REPLAY_DRIVER Allows you to specify the path to the recordreplay.so driver library.
