This repository contains the core infrastructure for policyengine.org. Namely:

• policyengine, a Python package which contains the server-side implementations, and
• policyengine-client, a React library containing high-level components to build the client-side interface.

NOTE: requires Python 3.7

First, ensure you have pnpm installed: https://pnpm.io/installation.

Then, install using make install. Then, to debug the client, run make debug-client, or to debug the server, run make debug-server.

If your changes involve the server, change useLocalServer = false; to useLocalServer = true; in policyengine-client/src/countries/country.jsx. Otherwise, change usePolicyEngineOrgServer = false; to usePolicyEngineOrgServer = true; in policyengine-client/src/countries/country.jsx.

If you don't have access to the UK Family Resources Survey, you can still run the UK population-wide calculator on an anonymised version. To do that, instead of running make debug-server, run UK_SYNTHETIC=1 make debug-server
