Sero is a modular TypeScript toolchain for FHIR (and friends) sponsored by Automate Medical Inc.

Serotinous trees like the sequoia only spread when they are exposed to the heat of fire:

These serotinous cones may remain green and closed for over twenty years (Buchholz 1938).

Health data is spreading everywhere. FHIR is a big part of that. Sero is built for developers who need tools in the languages they know, with opinionated answers to solve common problems.

Features:

• Multiple feature-specific composable modules - including http clients and servers
• A minimal HTTP client for FHIR RESTful API operations as wrapper for Fetch
• A conformant (1.0 and 1.1) CDS Hooks Service implementation
• An unfinished REST API implementation for FHIR with base R4 resources
• Alpha In-memory Store design for persisting FHIR as a log
• Out of box typings support for FHIR R3 and R4 with generics, CDS Hooks

Roadmap:

• Resource specific routing engine
• GraphQL API implementation of base resources
• SMART Apps/Launching
• Access control
• Building a TS native Validator
• Executing CQL
• Profile support
• Deployment configurations
• Subscriptions/Streams

• Quick Start
• Docs
• Client
• CDS Hooks
• FHIR REST API
• Development
• License

Install node 14.x on your platform.

The default example will boot at port 8080. You can see the full example at example/full-server.ts

git clone https://github.com/automate-medical/sero
npm install
npm start

Documentation built from code is available on the gh-pages branch and at docs.sero.run

A Fetch-ful FHIR client. Easily read a Patient resource or most other FHIR operations as a thin wrapper over Fetch.

  const { read } = Client("https://r4.smarthealthit.org", {})
  await read("Patient", "87a339d0-8cae-418e-89c7-8651e6aab3c6").json() as fhir4.Patient;

Serotiny exposes Service and Card classes which can be used from the @sero/cds-hooks module.

"CDS Hooks" are a protocol separate from FHIR proper, but involve the use of its data structures.

Serotiny automatically scaffolds all of the necessary API routes in the spec when you create a new Service, and exposes a simple, typed function that executes on hookRequest events.

Building support for this protocol as a distribution/access channel for novel clinical decision making techniques is super easy with Serotiny. Because of its modular design, CDS Hooks can be run as a totally standalone service: example/cds-hooks.ts shows an instance of Serotiny in this configuration.

• Implements Discovery service call
• Implements HookRequest call, and invoking a service
• Implements Feedback call
• Loading Services from PlanDefinition is not currently possible
• Currently passes Touchstone with a warning

• https://www.hl7.org/fhir/clinicalreasoning-cds-on-fhir.html
• https://cds-hooks.org/

Sero exposes a Rest service that adds routes for batch, capabilityStatement, instanceOperations, and typeOperations routes and handlers.

It consomes an instance of http and appends the configurable list above.

We currently target the Node 14.x runtime. You can use nodemon to watch + compile on file system events with npm run watch + npm run dev.

npm install
npm run watch
npm run dev
