    request-capture-har

    Wrapper for request module that saves all network traffic data as a HAR file.

    Build Status NPM request-capture-har package

    Compatibility

    request >= 2.81.0 recommended, as it has much more detailed timings via timingPhases.

    request >= v2.75.0 required, at a minimum.

    Usage

    // wrap around your request module
    const RCH = require('request-capture-har');
    const requestCaptureHar = new RCH(require('request'));
     
    // ...
    // `requestCaptureHar.request` is your `request` module's API.
    // ...
    requestCaptureHar.request(uri, options, callback);
     
    // Save HAR file to disk
    requestCaptureHar.saveHar(`network-waterfall_${new Date().toISOString()}.har`);
     
    // You can also clear any collected traffic
    requestCaptureHar.clearHar();

    This repo is a fork of larsthorup's node-request-har-capture. Instead of monkey-patching request-promise, the API allows you to pass in the general request module. We also added better support for transfer timings.

    image Above is a HAR captured by using request-capture-har from within npm to capture an npm install.

    Background

    This is especially useful for capturing all test traffic from your back-end test suite, for doing auto mocking in your front-end test suite. See this project for an example: https://github.com/larsthorup/http-auto-mock-demo. Blog post about this technique: http://www.zealake.com/2015/01/05/unit-test-your-service-integration-layer/

    Install
