beat-jev

Penalty shootout game against Jev, run as a Render Workflows task with scores in Postgres, in TypeScript and Python versions.

Libraryprototype
View on GitHub ↗

Overview

Beat Jev is a penalty shootout where you take turns shooting and keeping goal against TypeSafe Jev. It is an example app for Render: one Render Workflows task owns each match and scores are saved in Render Postgres, with separate TypeScript and Python examples sharing a 3D frontend and game rules, each with a live game.

The README focuses on infrastructure details, such as how a lost reply when starting a match is recovered by reusing an idempotency key derived from the match, and the limits of that deduplication. How Jev picks shots and dives is in the per-language READMEs, not the top-level one.

What the decision model decides

TypeQuestionAnswers
ChoiceWhere should Jev shoot, or which way should it dive?(inferred)—

How it works

  1. Player starts a match; a Workflow run owns it
  2. Each turn, Jev picks a shot or save direction
  3. Result stored in Postgres
  4. Match continues until a winner

Strengths

  • Shows durable workflow patterns around a decision model
  • Two language implementations

Caveats

  • Each example deploys a paid Postgres database
  • Jev details are in sub-READMEs

Getting started

Follow the TypeScript or Python README to deploy the web service, workflow and database on Render.
