SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you set up and develop Holochain hApps by guiding you through key concepts, packaging, zome development, and conductor configuration so your distributed Rust/WASM code can be validated and tested reliably.

Core Features & Use Cases

  • Scaffold and package hApps: Create a new hApp, then pack DNA and the full application for running in a conductor or sandbox.
  • Implement Zomes with Rust/HDK: Define entries, link types, extern functions, and validation rules to store and query DHT data.
  • Configure and test locally: Use a conductor configuration pattern plus unit tests (SweetConductor) and integration tests (Tryorama) to verify behavior.

Use case example: You’re building a social app where users create posts (entries) and retrieve them via DHT queries and linked relationships.

Quick Start

Create a new hApp named my-happ, scaffold its DNA/zome structure, then pack the DNA and application so you can start writing and running zome code.

Frequently Asked Questions about Holochain Development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I scaffold and package a Holochain hApp for local testing?▼

To scaffold a Holochain hApp, create the project structure, implement Rust zomes, and pack the DNA and application files so the code can run in a local conductor or sandbox for testing.

How do I implement zomes in Rust to store and query DHT data?▼

Implement Rust zomes by using HDK entry and link definitions, extern functions, and validation rules to store entries, manage linked relationships, and query DHT data effectively within your hApp.

What is the best way to test Holochain zome behavior locally?▼

The best way to test Holochain zome behavior is using a conductor configuration pattern alongside unit tests with SweetConductor and integration tests with Tryorama to verify DHT-backed coordination.

Do I need lair-keystore configured to run a Holochain hApp conductor?▼

Yes, you need lair-keystore configured when setting up the conductor, because managing keystore and lair settings correctly is required to secure and run your Holochain hApp.

What are the limitations of building distributed applications with Holochain?▼

A key limitation is that you must strictly use HDK entry and link definitions, extern functions, and packing commands correctly, as improper conductor configuration or validation rules will prevent your hApp from running reliably.
