har-recorder

Use this package to capture HAR recordings from Chrome sessions or Selenium tests.

Selenium usage example

const { startRecording, endRecording } = HarRecorder();
 
// enable chrome remote debugging on port 9223
let chrome_options = new chrome.Options()
    .addArguments("--remote-debugging-port=9223");
 
driver = await new Builder()
    .setChromeOptions(chrome_options)
    .forBrowser('chrome')
    .build();
 
// start the recording on port 9223
await startRecording({ port: 9223 });
 
// do Selenium stuff 
await driver.navigate().to('http://www.google.com');
await driver.wait(until.elementLocated(By.name('identification')));
 
// save recording to file
endRecording('create-blog-post.har');
driver.quit();    

Installation

npm install har-recorder

Setup

An instance of either Chrome itself or another implementation needs to be running on a known port in order to use this module (defaults to localhost:9222).

API

The API consists of three parts:

• The constractor function which creates a new HarRecorder.

• startRecording([options]) which starts recording a given Chrome instance. The recording defaults to localhost:9222. Overide this by passing a CDP options object.

• endRecording(filePath) which saves the HAR recording to a file and resets the stored requests.
