Usepip to installroute-detect:

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

You can check thatroute-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.

route-detect provides theroutes CLI command and usessemgrep to search for routes.

Use thewhich subcommand to pointsemgrep at the correct web application rules:

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

Use theviz 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 specialall 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 copyroute-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

route-detect usespoetry for dependency and configuration management.

Before proceeding, install project dependencies with the following command:

$ poetry install --with dev

Lint all project files with the following command:

$ poetry run pre-commit run --all-files

Run Python tests with the following command:

$ poetry run pytest --cov

Run Semgrep rule tests with the following command:

$ poetry run semgrep --test --config routes/rules/ tests/test_rules/
