romulus
is a tool designed to provide structure and a set of patterns
for React Native applications.
It should help eliminate the time you spend bootstrapping each project and give you consistency between your application builds.
While this comes with some opinion, there’s no overarching framework on top of React Native; it’s purely a collection of commonly used modules and some sensible architecture to get you or your team off the ground.
- Features - adds a set of commonly required features (e.g. Redux setup, offline storage, environment variables and more) by taking advantage of great community driven packages
- Structure - provides a sensible structure for your applications that helps bring consistency within your team or just between your own applications
- Scaffolding - makes it easy to scaffold new components, reducers and scenes that follow the same style and structure
View the example application created with Romulus
to get an idea of what romulus init
does. The application is ready to be cloned down and ran
straight away onto a device or simulator.
npm install -g romulus-cli
yarn global add romulus-cli
Don’t want to install anything? You can run the commands directly using
npx
(available with npm@5.2.0
).
npx romulus-cli init
Create a new React Native project using their CLI tool.
npx react-native init MyApp --template react-native-template-typescript
cd MyApp
You need to ensure you have the correct cli installed for this command to succeed.
npm uninstall -g react-native-cli npm i -g @react-native-community/cli
Once this is complete, simply run the main generator command. This will rework
and add to the files that are generated by React Native and give you something
more akin to what you might find with rails new
.

log
helper to output coloured logs to the debug console- Visual display of your app’s environment while it’s running, this gets hidden in production
- Optional support for different locales using
react-native-i18n
- Environment variables available in JavaScript, Objective C and Java using
react-native-config

redux-saga
(optional, not available withreact-query
) - Initial setup for deep linking
- Requests are set up to be handled with
axios
with clear logging in the debugger provided - Automatic versioning of iOS and Android versions based on the
package.json
version - Generic app icon that can be processed through a separate generator to handle all your iOS and Android icons
After running the base
command, on top of the features above your application
will then receive this structure.
