SMART Launcher

This server acts as a proxy that intercepts requests to otherwise open FHIR servers and requires those requests to be properly authorized. It also provides a SMART implementation that is loose enough to allow for apps to launch against this server without having to register clients first.

Installation

Make sure you have git and NodeJS 16 or higher, and then run:

git clone https://github.com/smart-on-fhir/smart-launcher-v2
cd smart-launcher-v2
npm i

Configuration

Although this server is designed to work without any configuration, one might want to customize a few things. To do so, create a file named .env in the root folder of the project. There is a file named example.env containing some default settings which you can copy and rename to .env:

mv example.env .env

Then read the comments above each environment variable and decide what you would like to change.

NOTE: The .env file is included in .gitignore and cannot be pushed with git. If you want to deploy this to remote server, you will have to create another .env file on the server, or set those environment variables in some other way.

Usage

There are two major ways to start the launcher:

Starting in production mode

Use when you want to run the launcher normally, either locally or deployed online.

1. Set NODE_ENV = "production" in your .env file (unless it is already set in your environment)
2. Set PORT in your .env file (unless it is already set in your environment)
3. Make sure LAUNCHER_PORT env variable is not set
4. Run npm run build
5. Run npm start

Starting in development mode

Use when you want to modify the source code.

1. Set NODE_ENV = "development" in your .env file
2. Run npm run start:server:watch to start the backend
3. In another terminal run npm start to start the frontend
4. Optionally, in another terminal run npm npm run test:server:watch to test changes

Testing

• To execute the backend tests run test:server
• To execute the backend tests continuously run test:server:watch
• To check the code coverage, after executing the tests open coverage/lcov-report/index.html

Key generation

To generate new certificates for your ssl server:

1. Make sure you have openssl (comes pre-installed on Mac)
2. cd to the project root
3. Execute npm run cert Then (re)start the server and it will use the new keys.

Using Docker

The launcher is also available as a Docker image. To use that simply run

docker run -t -p 8080:80 smartonfhir/smart-launcher-2:latest

and open http://localhost:8080
