aidbox-react

Build Status Coverage Status

TypeScript library consisting of set of utils, functions and React hooks to work with Aidbox's FHIR API. Based on axios.

So basically it is a javascript/typescript Aidbox FHIR-client. The main difference between FHIR and Aidbox data structure in our case is Reference's format. Aidbox uses two separate fields: resourceType and id while FHIR uses resourceType/id. Read more

Install

Clone this repository into src/contrib/aidbox-react and provide type definitions for aidbox in src/contrib/aidbox (see example/basic set of Aidbox typings)

Introduction

RemoteData

RemoteData is a wrapper over data.

It could have four statuses:

  • Success
  • Failure
  • Loading
  • NotAsked

RemoteDataResult is a subset of RemoteData and it could have two statuses:

  • Success
  • Failure

When we make a request to a server with any of library's methods, we'll probably get RemoteData as a result. Then we can easily check what've got.

Simplified example
import React from 'react';
// Your Aidbox typings. Read above in Install section of this Readme
import { Patient } from 'contrib/aidbox';  
import { getFHIRResource } from 'aidbox-react/lib/services/fhir';
import { isFailure, isSuccess } from 'aidbox-react/lib/libs/remoteData';

async function loadPatientGender() {
    const patientResponse = await getFHIRResource<Patient>({
        resourceType: 'Patient',
        id: 'patient-id',
    });
    if (isSuccess(patientResponse)) {
        return `Patient name is ${patientResponse.data.gender ?? 'unknown'}`;
    }
    if (isFailure(patientResponse)) {
        return `
            Failed to request patient,
            status: ${patientResponse.status},
            error : ${patientResponse.error}
        `;
    }
}

Content

We consider service as a function that returns RemoteDataResult<S, F> (RemoteDataSuccess<S> | RemoteDataSuccess<F>). For details, see RemoteData interface in aidbox-react/libs/remoteData.ts

Available functions (services)

  • service({...axiosConfig})
  • FHIR-specific:
    • getFHIRResource(reference)
    • getFHIRResources(resourceType, params)
    • getAllFHIRResources(resourceType, params)
    • findFHIRResource(resourceType, params)
    • saveFHIRResource(resource)
    • createFHIRResource(resource)
    • updateFHIRResource(resource, params)
    • patchFHIRResource(resource, params)
    • saveFHIRResources(resources, bundleType)
    • deleteFHIRResource(resources)
    • forceDeleteFHIRResource(resource)

service({...axiosConfig})

Basic function for making requests.

import { service } from 'aidbox-react/lib/services/service';
import { formatError } from 'aidbox-react/lib/utils/error';
import { isFailure, isSuccess } from 'aidbox-react/lib/libs/remoteData';

async function deleteAccount() {
    const result = await service({
        url: '/User/$delete-account',
        method: 'POST',
    });
    if (isSuccess(result)) {
        await logout();
    } else if (isFailure(result)) {
        console.error(formatError(result.error));
    }
}

getFHIRResource

Get resource by reference (resource type and id).

import { getFHIRResource } from 'aidbox-react/lib/services/fhir';
// ...

const observationResponse = await getFHIRResource<Observation>(makeReference('Observation', 'observation-id'));

getFHIRResources

Get resources using Search API Returns only first page of resources.

import { getFHIRResources } from 'aidbox-react/lib/services/fhir';
// ...

const qrBundleResponse = await getFHIRResources<QuestionnaireResponse>('QuestionnaireResponse', {
    subject: subject.id,
    questionnaire: 'intake',
    status: 'completed',
});
if (isSuccess(qrBundleResponse)) {
    // Iterate over found resources
    qrBundleResponse.data.entry?.forEach((bundleEntry) => {
        console.log(bundleEntry.resource?.status);
    });
}

getAllFHIRResources

Get all found resources from all pages.

import moment from 'moment';
import { getAllFHIRResources } from 'aidbox-react/lib/services/fhir';
import { formatFHIRDateTime } from 'aidbox-react/lib/utils/date';
// ...

const observationsResponse = await getAllFHIRResources<Observation>('Observation', {
    _sort: '-date',
    _count: 500,
    patient: 'patient-id',
    status: 'final',
    date: [`ge${formatFHIRDateTime(moment())}`],
});

findFHIRResource

Uses Search API to find exactly one resource and return in (not bundle). It throws Error('Too many resources found') if more than one resources were found and Error('No resources found') if nothing were found.

import { findFHIRResource } from 'aidbox-react/lib/services/fhir';

const roleResponse = await findFHIRResource<PractitionerRole>('PractitionerRole', {
    practitioner: 'practitioner-id',
});

saveFHIRResource

Saves resource. If resource has id – uses PUT method (updates), otherwise POST (creates). If you want to have more control, you can use createFHIRResource or updateFHIRResource functions.

import { saveFHIRResource } from 'aidbox-react/lib/services/fhir';
// ...

const saveResponse = await saveFHIRResource({
    resourceType: 'Patient',
    gender: 'female',
});

if (isFailure(saveResponse)) {
    console.warn('Can not create a patient: ', JSON.stringify(saveResponse.error));
}

createFHIRResource(resource)

Creates resource via POST command. The difference with saveFHIRResource is that createFHIRResource always use POST, even if resource has id field.

const resource = {
    id: '1',
    resourceType: 'Patient',
};

await createFHIRResource(resource);

updateFHIRResource(resource, params)

Updates resource using PUT request.

It's required to have either resource's id or pass params.

const resource = {
    resourceType: 'Patient',
    name: [{text: 'Alex'}]
};
const searchParams = { identifier: 'alex-1' };

const updateResponse = await updateFHIRResource(resource, searchParams);

patchFHIRResource(resource, params)

Use PATCH method to patch a resource.

It's required to have either resource's id or pass params.

const resource = {
    resourceType: 'Patient',
    name: [{text: 'Jennifer'}],
    gender: 'female'
};

const createResponse = await createFHIRResource(resource);
if (isSuccess(createResponse)) {
    const patchResponse = await patchFHIRResource({
        id: createResponse.data.id,
        name: [{text: 'Monica'}]
    });
}

saveFHIRResources(resources, bundleType)

Save an array of resources using POST request.

Method for every resource will be either PUT (if resource's id presented) or

const bundleResponse = await saveFHIRResources([
    {
        id: 'jennifer-1',
        resourceType: 'Patient',
        name: [{text: 'Jennifer'}]
    },
    {
        resourceType: 'Patient',
        name: [{text: 'Monica'}]
    }
], 'transaction');

deleteFHIRResource(resources)

Actually it doesn't delete a resource, just mark it as deleted by altering its status (see inactiveMapping list in fhir.ts).

await deleteFHIRResource(makeReference('Patient', 'patient-id'));

forceDeleteFHIRResource(resource)

Deletes resource by calling DELETE method.

const createResponse = await createFHIRResource({
    resourceType: 'Patient',
    name: [{text: 'Max'}]
});
if (isSuccess(createResponse)) {
    const deleteResource = await forceDeleteFHIRResource(makeReference('Patient', createResponse.data.id));
}

Available hooks

  • useService(serviceFn)
  • usePager(resourceType, resourcesOnPage?, searchParams?)
  • useCRUD(resourceType, id?, getOrCreate?, defaultResource?) - WIP

Usage

Set baseURL and token for axios instance using setInstanceBaseURL and setInstanceToken/resetInstanceToken from aidbox-react/services/instance And use hooks and services

Examples

Pager hook

import * as React from 'react';

import { User } from 'shared/src/contrib/aidbox';
import { usePager } from 'src/contrib/aidbox-react/services/service';
import { isLoading, isSuccess } from 'src/contrib/aidbox-react/libs/remoteData';
import { extractBundleResources } from 'src/contrib/aidbox-react/services/fhir';

export function UserList(props: {}) {
    const [resourcesResponse, pagerManager] = usePager<User>('User', 2);

    if (isLoading(resourcesResponse)) {
        return <div>Loading...</div>;
    }

    if (isSuccess(resourcesResponse)) {
        const users = extractBundleResources(resourcesResponse.data).User || [];

        return (
            <div>
                <a onClick={() => pagerManager.loadNext()}>Load next</a>

                {users.map((user) => (
                    <div key={user.id}>{user.id}</div>
                ))}
            </div>
        );
    }

    return null;
}

CRUD hook

import * as React from 'react';

import { useCRUD } from 'src/contrib/aidbox-react/hooks/crud';
import { isLoading, isSuccess } from 'src/contrib/aidbox-react/libs/remoteData';
import { Patient } from 'shared/src/contrib/aidbox';

export function UserList(props: {}) {
    const [resourceResponse, crudManager] = useCRUD<Patient>('Patient', 'toggle', true, {
        resourceType: 'Patient',
        active: false,
    });

    if (isLoading(resourceResponse)) {
        return <div>Loading...</div>;
    }

    if (isSuccess(resourceResponse)) {
        // This is just an example
        const active = resourceResponse.data.active;

        return (
            <div>
                Active: {active ? 'Yes' : 'No'}
                <a
                    onClick={() =>
                        crudManager.handleSave({
                            ...resourceResponse.data,
                            active: !active,
                        })
                    }
                >
                    Toggle
                </a>
            </div>
        );
    }
    return null;
}
