Waves node is a host connected to the blockchain network with the next functions:

Learn more about Waves Node in the documentation.

🚀️ Getting started

A quick introduction of the minimal setup you need to get a running node.

Prerequisites:

Linux systems:

sudo apt-get update
sudo apt-get install openjdk-8-jre
java -jar node/target/waves-all*.jar path/to/config/waves-{network}.conf

Mac systems (assuming already installed homebrew):

brew cask install adoptopenjdk/openjdk/adoptopenjdk8
java -jar node/target/waves-all*.jar path/to/config/waves-{network}.conf

Windows systems (assuming already installed OpenJDK 8):

java -jar node/target/waves-all*.jar path/to/config/waves-{network}.conf

Using docker image:

docker run -p 6869:6869 -p 6868:6868 -e WAVES_NETWORK=MAINNET -e WAVES_LOG_LEVEL=DEBUG -e WAVES_HEAP_SIZE=2g -v YOUR_LOCAL_PATH_HERE:/waves wavesplatform/node

More details on how to install a node for different platforms you can find in the documentation.

🔧 Configuration

The best starting point to understand available configuration parameters is the this article.

The easiest way to start playing around with configurations is to use default configuration files for different networks, they're available here.

Logging configuration with all available levels and parameters is described here.

👨‍💻 Development

The node can be built and installed wherever Java can run. To build and test this project, you will have to follow these steps:

Show instructions *1. Setup the environment.* - Install Java for your platform: ```bash sudo apt-get update sudo apt-get install openjdk-8-jre # Ubuntu # or # brew cask install adoptopenjdk/openjdk/adoptopenjdk8 # Mac ``` - Install SBT (Scala Build Tool) Please follow the SBT installation instructions depending on your platform ([Linux](https://www.scala-sbt.org/1.0/docs/Installing-sbt-on-Linux.html), [Mac](https://www.scala-sbt.org/1.0/docs/Installing-sbt-on-Mac.html), [Windows](https://www.scala-sbt.org/1.0/docs/Installing-sbt-on-Windows.html)) *2. Clone this repo* ```bash git clone https://github.com/wavesplatform/Waves.git cd Waves ``` *3. Compile and run tests* ```bash sbt checkPR ``` *4. Run integration tests (optional)* Create a Docker image before you run any test: ```bash sbt node-it/docker ``` - Run all tests. You can increase or decrease number of parallel running tests by changing `SBT_THREAD_NUMBER` ```bash SBT_THREAD_NUMBER=4 sbt node-it/test ``` - Run one test: ```bash sbt node-it/testOnly *.TestClassName # or # bash node-it/testOnly full.package.TestClassName ``` *5. Build packages* ```bash sbt packageAll # Mainnet sbt -Dnetwork=testnet packageAll # Testnet ``` `sbt packageAll` ‌produces only `deb` package along with a fat `jar`. *6. Install DEB package* `deb` package is located in target folder. You can replace '*' with actual package name: ```bash sudo dpkg -i node/target/*.deb ``` *7. Run an extension project locally during development (optional)* ```bash sbt "extension-module/run /path/to/configuration" ``` *8. Configure IntelliJ IDEA (optional)* The majority of contributors to this project use IntelliJ IDEA for development, if you want to use it as well please follow these steps: 1. Click on `Add configuration` (or `Edit configurations...`) 2. Click on `+` to add a new configuration, choose `Application` 3. Specify: - Main class: `com.wavesplatform.Application` - Program arguments: `/path/to/configuration` - Use classpath of module: `extension-module` 4. Click on `OK` 5. Run this configuration
