SHEATH - Ranvier World Viewer and Editor

This is an Electron/React/Redux app being developed alongside Ranvier, a MUD engine written in NodeJS. Eventually, Sheath will be a full-featured world-viewer and editor.

Planned features:

  • Viewing all loaded items, players, NPCs, rooms, and areas.
  • Viewing all definitions of items, NPCs, rooms.
  • Cloning/spawning items, NPCs, and room from definition files.
  • Creating new definitions that will be stored and persisted by the MUD server.
  • ???
  • Profit.

Built with electron-react-boilerplate

Electron application boilerplate based on React, Redux, React Router, Webpack, React Transform HMR for rapid application development


  • Note: requires a node version >= 6 and an npm version >= 3.
  • If you have installation or compilation issues with this project, please see our debugging guide

ProTip: Install with yarn for faster and safer installation

$ cd sheath-ranviermud && npm install


Run these two commands simultaneously in different console tabs.

$ npm run hot-server
$ npm run start-hot

or run two servers with one command

$ npm run dev

Optional Editor Configuration


apm install editorconfig es6-javascript atom-ternjs javascript-snippets linter linter-eslint language-babel autocomplete-modules




Toggle Chrome DevTools

  • OS X: Cmd Alt I or F12
  • Linux: Ctrl Shift I or F12
  • Windows: Ctrl Shift I or F12

See electron-debug for more information.

DevTools extension

This boilerplate is included following DevTools extensions:

You can find the tabs on Chrome DevTools.

If you want to update extensions version, please set UPGRADE_EXTENSIONS env, just run:

$ UPGRADE_EXTENSIONS=1 npm run dev

# For Windows
$ set UPGRADE_EXTENSIONS=1 && npm run dev

CSS Modules

This boilerplate out of the box is configured to use css-modules.

All .css file extensions will use css-modules unless it has .global.css.

If you need global styles, stylesheets with .global.css will not go through the css-modules loader. e.g.

If you want to import global css libraries (like bootstrap), you can just write the following code in .global.css:

@import "~bootstrap/dist/css/bootstrap.css";


To package apps for the local platform:

$ npm run package

To package apps for all platforms:

First, refer to Multi Platform Build for dependencies.


$ npm run package-all

To package apps with options:

$ npm run package -- --[option]

Further commands

To run the application without packaging run

$ npm run build
$ npm start

To run End-to-End Test

$ npm run build
$ npm run test-e2e


See electron-builder CLI Usage

Module Structure

This boilerplate uses a two package.json structure.

  1. If the module is native to a platform or otherwise should be included with the published package (i.e. bcrypt, openbci), it should be listed under dependencies in ./app/package.json.
  2. If a module is imported by another module, include it in dependencies in ./package.json. See this ESLint rule.
  3. Otherwise, modules used for building, testing and debugging should be included in devDependencies in ./package.json.

Static Type Checking

This project comes with Flow support out of the box! You can annotate your code with types, get Flow errors as ESLint errors, and get type errors during runtime during development. Types are completely optional.

Native-like UI

If you want to have native-like User Interface (OS X El Capitan and Windows 10), react-desktop may perfect suit for you.

Dispatching redux actions from main process

see discusses in #118 and #108

How to keep the boilerplate updated

If your application is a fork from this repo, you can add this repo to another git remote:

git remote add upstream

Then, use git to merge some latest commits:

git pull upstream master
