Is there any tool for parsing raw network data which is collected by Chrome remote debugging protocol?

[Chen Yang]

I want to parse the raw network data collected by Chrome remote debugging protocol. But it's too complicated. 

Is there any tool to parse it ? Just like what https://github.com/paulirish/devtools-timeline-model do for raw timeline data.

Maybe make an extension?

You kind of need devtools-network-manager. Lighthouse folks, have you extracted it for reuse similarly to timeline?

Yup!

It's pretty straightforward to reuse front_end/sdk/NetworkManager.js

Here's what we did in Lighthouse:

• lighthouse/network-recorder.js is what initalizes the WebInspector.networkManager, which what you want.
  
• lighthouse/web-inspector.js has our mocked WebInspector object, with a few stubs for our "headless" use.
  
• lighthouse/driver.js has the basic protocol bindings
  

It's not yet extracted cleanly into a standalone module like devtools-timeline-model, but it'd look something like these files.

(web-inspector.js would just be a bit cleaner with fewer stubs).

Thanks for your answer.

Actually,I want to do performance benchmark test among different versions of our app.So it's necessary to get the readable performance data.But there isn't a convenient way to parse raw data.I have spent a lot of time to read the source code of Chrome devtools and try to parse it by myself.But it's not enough.Especially for network data.

https://github.com/paulirish/devtools-timeline-model is really helpful for my current work. 

Hope to see more tools like this.
