React Native components for Engine by MoneyLion. This implements a turnkey flow for gathering user information and submitting them to the Engine service to find financial products.

Getting Started

Please reference Engine by MoneyLion's Developer Center for instructions and details to integrate the React Native Mobile SDK into your mobile app.

Development workflow

This project is managed using Yarn workspaces. It contains the following packages:

• The library package in this directory.
• An example app in the example/ directory.

To get started with the project, run yarn in this directory to install the required dependencies for each package:

yarn

Since the project relies on Yarn workspaces, you cannot use npm for development.

The example app demonstrates usage of the library. You need to run it to test any changes you make.

It is configured to use the local version of the library, so any changes you make to the library's source code will be reflected in the example app. Changes to the library's JavaScript code will be reflected in the example app without a rebuild, but native code changes will require a rebuild of the example app.

You can use various commands from this directory to work with the project.

To start the packager:

yarn example start

To run the example app on Android:

yarn example android

To run the example app on iOS:

yarn example ios

To run the example app on Web:

yarn example web

Make sure your code passes TypeScript and ESLint. Run the following to verify:

yarn typecheck
yarn lint

To fix formatting errors, run the following:

yarn lint:fix

Remember to add tests for your change if possible. Run the unit tests by:

yarn test

Scripts

The package.json file contains various scripts for common tasks:

• yarn: setup project by installing dependencies.
• yarn typecheck: type-check files with TypeScript.
• yarn lint: lint files with ESLint.
• yarn test: run unit tests with Jest.
• yarn example start: start the Metro server for the example app.
• yarn example android: run the example app on Android.
• yarn example ios: run the example app on iOS.

"Unable to boot simulator"

Sometimes you might encounter a problem where the iOS simulator refuses to start. This can present with an error message like Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding.

You might be able to fix it by clearing the simulator caches. Navigate to ~/Library/Developer/CoreSimulator/Caches and remove the files in there.
