jwt-claims-fhir

This is a trial implementation of the proposal to use jwt claims for fhir

Use

claims

Evaluate claims against a proposed action

//claims made in json web token
var scope_claims = ['Foo/12345'];
var action_claims = ['read:Foo', 'read:Bar'];

//scope and action to evaluate
var scope = '*';
var action = {op: 'read', type: 'Bar'};

if (lib.claims
    .authorise()
    .access(scope, scope_claims)
    .action(action, action_claims)
    .isAuthorised)
{
    console.log('authorised');
}

parser

Determine action from a request with url and method

var options = {
    base: 'https://fhir.example.net/svc/fhir'
};

var req = {
    url: 'https://fhir.example.net/svc/fhir/Foo/123',
    method: 'GET'
};

var action = lib.parser.parse(req, options);

console.log(action);

convert

Convert claims to SMART on FHIR scopes

var options = {
    read: ['$foo'],
    write: ['$bar'],
    '*': ['$anything']
};

var smart_scopes = lib.convert(options).toSMARTonFHIRscopes(claims);

console.log(smart_scopes);
