A virtual table top (VTT) web-based battle map editor and viewer for playing role-playing games remotely, specificially targetting Fate Core (but works with any rpg).
This repo contains a web application that supports people playing any kind of Fate Core based role playing game remotely using whatever video conferencing tool they like. This app provides a battle map for easier handling of combat situations.
The app allows the Game Master (GM) to draw a scene (with support for touch devices and stylus pens), draw "zones" (which are important in Fate) and place tokens which can be moved around. The drawing canvas has infinite size so the combat can evolve in whatever direction the story advances. Players can join the map and view it allowing them to move the scene and zoom in/out. All changes made by the GM are reflected in the players view.
The backend is implemented using Golang. The frontend is implemented using TypeScript and the wecco framework. Almost all CSS is coming from Tailwind with minimal CSS being written to embed the Fate Core font for displaying dice results. The battlemap editor and viewer are created as a separate module and are published as web components for easy embedding in other apps. The canvas drawing is handled by `@halimath/scenic which is contained in this repo but intentions are to move it to its own repo once feature set and maturity are relatively stable.
For being able to develop the app, you should have a local install of
- Golang >= 1.18beta2
- Node v16
- NPM (>=8.1)
You should also have an IDE which supports TypeScript. VSCode works perfectly, IntelliJ IDEA works, too. I haven't tried other IDEs, but the should work the same.
To start development, you need to open four terminal (tabs) for each of the following directories:
- scenic
- battlemap
- app
- backend
Run the following command in each of the first three terminals:
$ npm i
$ npm startand run
$ go run .in the third one. This will start the dev server and bring up the app on localhost:3000. The backend runs on
localhost:8080 but only the rest api backend part is needed.
All parts of the application are wrapped in a single OCI container build with docker. The container build
uses multiple stages and builds the whole app as part of the container build. The final container will only
contain the compiled application, though.
We use Github Actions to build the application, run the tests, build the container image and publish it to https://ghcr.io.
