Quick Start

Prerequisites and Installation

iCure can easily be used in the browser or with Node.

Node version 16 or higher is fully supported as it includes a webcrypto compatible implementation of the cryptography layer.

We recommend using yarn for package management but npm works fine as well.

The main dependency for using iCure is @icure/medical-device-sdk, two extra dependencies are required for node : isomorphic-fetch and node-localstorage.

mkdir healthcare-project
cd healthcare-project
yarn init -y
yarn add @icure/medical-device-sdk

#if you are using node two other dependencies are needed
yarn add isomorphic-fetch node-localstorage

Installing the backend or using iCure cloud

iCure can be installed locally or in the cloud.

The cloud version is available on and can be configured using our cockpit.

If, instead of using the cloud version, you want to install the iCure API locally, you can either use docker (recommended) or install it manually.

Using iCure Cloud

Head to and create an account. Create an app and create a new administrator in the app.

Note down the credentials of your administrator. You will need them later.

Using docker

Make sure you have docker installed and running on your machine.

Then, run the following command:

mkdir icure-api
cd icure-api
curl -O
docker compose up -d

The current version of iCure is called the Kraken. The docker compose file will start the Kraken and a CouchDB instance. Kraken connects to the couchdb database to store its data.


The docker compose file exposes the Kraken on port 16043. It also exposes the CouchDB instance on port 5984.

To connect to the Kraken, you will need credentials. If no user has ever been created in the database, an entry similar to the one below will appear in the docker logs:

2022-09-30 07:39:06.700 WARN 7 --- [ main] ication$$EnhancerBySpringCGLIB$$71ea0610 : Default admin user created with password d2217dd39238

The password is going to be used later. Please note them down.

Manual installation

You can also install the Kraken manually without relying on docker. This involves installing and configuring a local or remote instance of CouchDB and then installing and starting the Kraken jar.

Using the SDK

Now that we have credentials for a local or remote instance of the Kraken, we can use the SDK to connect to it.

You can either define the environment variables ICURE_USER_NAME and ICURE_USER_PASSWORD or directly modify the code below and replace the credentials loaded from the environment by the ones you noted down earlier.

If you use the cloud version, this is the credentials you got from the cockpit. If you use the local installation, the credentials are admin and the passwordyou got from the logs.

import 'isomorphic-fetch'
import { medTechApi } from '@icure/medical-device-sdk'
import { webcrypto } from 'crypto'
import * as process from 'process'

export const host = process.env.ICURE_URL ?? ''
export const username = process.env.ICURE_USER_NAME
export const password = process.env.ICURE_USER_PASSWORD

const api = await medTechApi()
.withCrypto(webcrypto as any)

Once logged in, you can check the user details.

const user = await api.userApi.getLoggedUser()

Congratulations, you are now ready to use the SDK to interact with the iCure API. You can now head to the Tutorial to learn how to use the SDK to create a simple application.
