Set up development environment
This section covers everything you need to get started with dapp development. It provided information about installing and configuring your local development environment for developing dapps on Chromia blockchain.
Rell needs PostgreSQL 16.3 for running nodes. Default setup: database 'postchain' with 'postchain' credentials.
Ensure PostgreSQL 16.3 and Java 21+ are set up. Install the Chromia CLI via package managers (e.g., Homebrew) or download directly. For Docker, use the provided image.
In VS Code, go to Extensions, search for 'Rell', and click Install.
In JetBrains IDE, go to File -> Settings -> Plugins, search for 'Rell' in the Marketplace, and click Install.
Install Postchain clients for JavaScript/TypeScript via npm (npm install postchain-client), Kotlin via
Maven/Gradle, or C# via NuGet or DLLs.
Use Github Dev Container to make the first steps with Chromia tools.
Use Docker with devcontainer support for a fully pre-configured development environment. Requires Docker, VS Code, and devcontainer extension.
