Installing

Use pip to install route-detect:

$ python -m pip install --upgrade route-detect

You can check that route-detect is installed correctly with the following command:

$ echo 'print(1 == 1)' | semgrep --config $(routes which test-route-detect) -
Scanning 1 file.

Findings:

  /tmp/stdin
     routes.rules.test-route-detect
        Found '1 == 1', your route-detect installation is working correctly

          1┆ print(1 == 1)


Ran 1 rule on 1 file: 1 finding.

Using

route-detect provides the routes CLI command and uses semgrep to search for routes.

Use the which subcommand to point semgrep at the correct web application rules:

$ semgrep --config $(routes which django) path/to/django/code

Use the viz subcommand to visualize route information in your browser:

$ semgrep --json --config $(routes which django) --output routes.json path/to/django/code
$ routes viz --browser routes.json

If you're not sure which framework to look for, you can use the special all ID to check everything:

$ semgrep --json --config $(routes which all) --output routes.json path/to/code

If you have custom authn or authz logic, you can copy route-detect's rules:

$ cp $(routes which django) my-django.yml

Then you can modify the rule as necessary and run it like above:

$ semgrep --json --config my-django.yml --output routes.json path/to/django/code
$ routes viz --browser routes.json
