Quickstart

  1. Install Node.js v8.0.0 or higher.
  2. On Ubuntu, install git and build-essential: sudo apt-get install -y git build-essential.
  3. Install gulp globally: sudo npm install -g gulp or yarn global add gulp.
  4. Clone this repository git clone https://github.com/nimiq-network/core.
  5. In the core directory, run npm install or yarn.
  6. In the core directory, run npm run build or yarn build.
  7. Open clients/browser/(full|light|nano).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 Browser client

Open clients/browser/(full|light|nano).html in your browser.

Run Node.js client

To run a Node.js 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 <ssl-key> --cert <ssl-certificate> [--wallet-seed <seed>] [--wallet-address <address>] [--miner [<threads>]] [--statistics[=<interval>]]
Argument Description
host Hostname of the Node.js client.
port Port used to communicate with the peers.
key SSL private key for your domain.
cert SSL certificate of your domain.
wallet-seed Your wallet seed (optional).
wallet-address Your wallet address for mining (optional, can only be used without wallet-seed).
miner The number of threads to start for mining (optional).
statistics The interval in seconds to output miner statistics (optional, default: 10).

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)

  • Node.js latest version (> 8.0.0)

  • Dependencies: npm install

  • Node.js dependencies:

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

Installation for Core Developers (using yarn)

  • Node.js latest version (> 8.0.0)

  • Dependencies: yarn

  • Node.js 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>
