SMART on FHIR JavaScript Library
================================

This is a JavaScript library for connecting SMART apps to FHIR servers.
It works both in browsers (IE 10+) and on the server (Node 10+).

## Browser Usage

In the browser you typically have to create two separate pages that correspond to your
`launch_uri` (Launch Page) and `redirect_uri` (Index Page).

### As Library

```html
<!-- launch.html -->
<script src="./node_module/fhirclient/build/fhir-client.js"></script>
<script>
FHIR.oauth2.authorize({
    "client_id": "my_web_app",
    "scope": "patient/*.read"
});
</script>

<!-- index.html -->
<script src="./node_module/fhirclient/build/fhir-client.js"></script>
<script>
FHIR.oauth2.ready()
    .then(client => client.request("Patient"))
    .then(console.log)
    .catch(console.error);
</script>
```

### As Module
```js
import FHIR from "fhirclient"

// Launch Page
FHIR.oauth2.authorize({
    "client_id": "my_web_app",
    "scope": "patient/*.read"
});

// Index Page
FHIR.oauth2.ready()
    .then(client => client.request("Patient"))
    .then(console.log)
    .catch(console.error);
```

## Server Usage
The server is fundamentally different environment than the browser but the
API is very similar. Here is a simple Express example:
```js
const fhirClient = require("fhirclient");

// This is what the EHR will call
app.get("/launch", (req, res) => {
    fhirClient(req, res).authorize({
        "client_id": "my_web_app",
        "scope": "patient/*.read"
    });
});

// This is what the Auth server will redirect to
app.get("/", (req, res) => {
    fhirClient(req, res).ready()
        .then(client => client.request("Patient"))
        .then(res.json)
        .catch(res.json);
});
```
