Install depot_tools, then:
fetch https://chromium.googlesource.com/catapult cd catapult/netlog_viewer/netlog_viewer
cd catapult/netlog_viewer ./bin/serve_static
The Net Log viewer has no server-side dependencies, so it can be loaded through index.html using any static HTTP server (provided components/ is also mapped). See the serve_static script above for an example.
This is convenient for development using an edit/reload cycle, however this is not quite what is deployed to https://netlog-viewer.appspot.com/.
cd catapult ./bin/run_dev_server --no-install-hooks --port 8111
Now navigate to http://localhost:8111/netlog_viewer/tests.html to run the tests and see their results.
Note that running the tests in headless mode does not currently work (i.e. netlog_viewer/bin/run_dev_server_tests).
cd catapult/netlog_viewer ./netlog_viewer_build/build_for_appengine.py
This command will package all the HTML/JavaScript/CSS into a single vulcanized.html file under catapult/netlog_viewer/appengine/static/ (the build outputs will show up as an untracked files by git, and should not be committed).
The bundled app can be served by any static server. To test it using Flask, serve it with:
cd catapult/netlog_viewer/appengine pip3 install -r requirements.txt python3 main.py
You may want to use venv to install Flask in a virtual environment.
Only certain project OWNERS can publish the checked in code to https://netlog-viewer.appspot.com/.
For those members, here are the internal instructions.
File a bug using this chromium bug template which will add the component Internals>Network>Logging. Please also prefix the title with [NetLogViewer].
Changes should be proposed using a Gerrit code review, with the reviewer set to one of the NetLog OWNERS. For instructions on how to use the code review system, see catapult/CONTRIBUTING.md.
This viewer code was extracted from Chromium and has not yet been modernized.
