2. Run npm install or yarn
3. Run npm run build or yarn build
4. Open clients/browser/index.html in your browser to access the Browser Client.

Web Developers

Most simple Web Application on top of the Nimiq Blockchain

A good way to get started is to have a look at the most simple web application on top of the Nimiq Blockchain.

Installation for Web Developers

Follow the Quickstart guide or use our CDN:

<script src="https://cdn.nimiq.com/core/nimiq.js"></script>

Run Client

Run Browser Client

Open clients/browser/index.html in your browser.

Run NodeJs client

To run a NodeJs Client you will need a publicly routable IP, Domain and SSL Certificate (get a free one at letsencrypt.org). Start the client by running clients/nodejs/index.js.

cd clients/nodejs/
node index.js --host <hostname> --port <port> --key <privkey> --cert <certificate>

Argument	Description
host	Hostname of the NodeJs client.
port	Port used to communicate with the peers.
key	Private key for the client
cert	SSL certificate of your Domain.
wallet-seed	Your wallet seed (optional)

Build your own Browser client

Just include <script src="dist/nimiq.js"></script> in your project.

API

Visit the API Documentation.

Core Developers

Developers are free to choose between npm and yarn for managing the dependencies.

Installation for Core Developers (using npm)

• NodeJs latest version (> 7.9.0)

• Dependencies: npm install

• NodeJs dependencies:

   cd src/main/platform/nodejs/
   npm install
   cd clients/nodejs/
   npm install

Installation for Core Developers (using yarn)

• NodeJs latest version (> 7.9.0)

• Dependencies: yarn

• NodeJs dependencies:

   cd src/main/platform/nodejs/
   yarn
   cd clients/nodejs/
   yarn

Test and Build

Run Testsuite

• npm test or yarn test runs browser and NodeJS tests.
• npm run test-browser or yarn test-browser runs the testsuite in your browser only.
• npm run test-node or yarn test-node runs the testsuite in NodeJS only.

Run ESLint

npm run lint or yarn lint runs the ESLint javascript linter.

Build

Executing npm run build or yarn build concatenates all sources into dist/{web,web-babel,web-crypto,node}.js

Docker

A Dockerfile is provided which allows for creating your own backbone image using the following arguments.

Argument	Description
BRANCH	Defaults to master but can be any available git branch
PORT	Defaults to TCP port 8080
DOMAIN	Domain to be used for hosting the backbone node
KEY	Path to an existing certificate key for the DOMAIN
CRT	Path to an existing signed certificate for the DOMAIN
WALLET_SEED	Pre-existing wallet private key

Building the Docker image using the above arguments

docker build \
  --build-arg DOMAIN=<DOMAIN> \
  --build-arg BRANCH=<BRANCH> \
  --build-arg WALLET_SEED=<WALLET_SEED> \
  --build-arg KEY=<KEY> \
  --build-arg CRT=<CRT> \
  --build-arg PORT=<PORT> \
  -t nimiq .

Running an instance of the image

docker run -d -p 8080:8080 -v /etc/letsencrypt/:/etc/letsencrypt/ --name "nimiq" nimiq

Note that you can override any of the arguments which were baked into the image at runtime with exception to the BRANCH. The -v flag here allows for mapping a local system path into the container for the purpose of using the existing DOMAIN certificates.

Check status

docker logs -f <instance_id_or_name>
