Template for backend take home test #1

Pre-Requisites

1/ You will need to have docker compose v2: https://docs.docker.com/compose/install/

2/ You will need to have installed sqd cli: https://docs.subsquid.io/squid-cli/installation/#0-install-and-setup-squid-cli

3/ indexer folder in this repo is a typescript codebase. We recommend you use node v18.6.0. You can use nvm to manage node versions. cd into this folder and npm install deps. It's crucial that you use npm!

4/ poetry to manage python dependencies. You can install it here: https://python-poetry.org/docs/#installation

Repo Overview

• indexer - subsquid boilerplate for your indexing needs
• api - your python graphql server boilerplate

To install python dependencies, run poetry install. This will create a virtual environment in .venv in current workspace directory. Now you can run poetry shell and it will activate this virtual environment for you. Note, you will need to use python ^3.11 for this assignment. A neat way to manage multiple python versions at the same time is with pyenv.

Development

To start all the services, simply run:

docker compose up --build

This will start the following services:

• db
• api

Notes

You will have noticed that subsquid is serving indexed data via its very own GraphQL API server. Proxying into it from Python will be considered a fail. You must write your own Python GraphQL server over postgresql db tables.
