Stardew Valley Game Integration Extension

This Extension was built for the Twitch Dev Tour 2019 and showcases how viewers can vote on the in-game weather instead of relying on the game’s default weather algorithm. It has three main components: a frontend UI for the viewer and broadcaster, backend code (EBS) to manage voting and a game mod to manipulate the game state.

Building the Frontend

The frontend is written in Vue.js.

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

# build for production with minification
npm run build

# build for production and view the bundle analyzer report
npm run build --report

Building the Backend

The backend is written in Python and designed for a serverless setup via AWS Lambda. We’ve provided a Cloud Formation script if you’d like to deploy on AWS. First, you need install the SAM toolkit

Then run sam deploy -t databases.yaml followed by sam deploy -t functions.yaml within the templates folder.

The Game Mod

The interaction between Stardew valley running on the computer and our backend is controlled by a game mod. This mod handles polling the backend to check if a new weather condition is available, as well as forcing the weather change. The mod can be downloaded on Curse Forge.
