Quickstart

1. Install Node.js v8.0.0 or higher.
2. On Ubuntu and Debian, install git and build-essential: sudo apt-get install -y git build-essential.
   • On other Linux systems, install git, python2.7, make, gcc and gcc-c++.
   • For MacOS or Windows, check here for git and here for compilation tools.
3. Install yarn globally: sudo npm install -g yarn.
4. Install gulp globally: yarn global add gulp.
5. Clone this repository: git clone https://github.com/nimiq-network/core.
6. Build the project: cd core && yarn && yarn build.
7. Open clients/browser/index.html in your browser.

Web Developers

Simple Web Application on top of Nimiq

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

Getting Started

Follow the Quickstart guide or make use of our CDN:

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

Browser client

Open clients/browser/index.html in your browser or include <script src="dist/nimiq.js"></script> in your project.

Node.js client

To run a Node.js client you will need a publicly routable IP, Domain, and SSL Certificate (get a free certificate at letsencrypt.org). Start the client by running clients/nodejs/nimiq with the respective configuration.

Test and Build

Run Testsuite

• yarn test runs browser and Node.js tests.
• yarn test-browser runs the testsuite in your browser only.
• yarn test-node runs the testsuite in Node.js only.

Run ESLint

yarn lint runs the ESLint javascript linter.

Build

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

Build binary packages for Linux distributions

After completing the Quickstart, follow the steps below to build a Linux package. After the build process:

• the package will be located in the dist/ directory,
• once the package has been installed,
  • a configuration file will be located in /etc/nimiq/nimiq.conf and
  • a systemd service will be avialable which you can manage with systemctl start|stop|restart nimiq.

Debian/Ubuntu (deb package format)

1. Make sure you have dpkg, jq and fakeroot installed (otherwise, install with apt).
2. Run yarn run build-deb.
3. The deb package will be located in the dist/ directory.

Note: creating deb packages only works on Debian-based distributions and has been tested extensively on Ubuntu and Debian.

Fedora/CentOS/RHEL (rpm package format)

1. Make sure you have rpm-build installed (otherwise, install with yum or dnf).
2. Run yarn run build-rpm.
3. The rpm package will be located in the dist/ directory.

Note: creating rpm packages only works on rpm-based distributions and has been tested extensively on Fedora only.
