Chrome Android Dependency Analysis Visualization

Development Setup

Shell variables

This setup assumes Chromium is in a cr directory (~/cr/src/...). To make setup easier, you can modify and export the following variables:

export DEP_ANALYSIS_DIR=~/cr/src/tools/android/dependency_analysis
export DEP_ANALYSIS_JAR=~/cr/src/out/Default/obj/chrome/android/chrome_java__process_prebuilt.desugar.jar

Generate JSON

See ../README.md for instructions on using generate_json_dependency_graph.py, then generate a graph file in this directory (js/json_graph.txt) with that exact name:

cd $DEP_ANALYSIS_DIR
./generate_json_dependency_graph.py --target $DEP_ANALYSIS_JAR --output js/json_graph.txt

The following instructions assume you are in the dependency_analysis/js = $DEP_ANALYSIS_DIR/js directory.

Install dependencies

You will need to install npm if it is not already installed (check with npm -v), either from the site or via nvm (Node Version Manager).

To install dependencies:

npm install

(TEMP) Run visualization

To run the (highly temporary) Python server to serve the JSON at localhost:8888/json_graph.txt :

python3 -m http.server 8888

The visualization will make requests to this server for the JSON graph on load.

To view the visualization, open localhost:8888/index.html.

Miscellaneous

To run ESLint on the JS (and fix fixable errors) using npx (bundled with npm):

npx eslint --fix *.js
