forum

This is a basic Holochain training, with step by step exercises and their tests.

It consists of a forum hApp that has already been implemented, both its backend and a small UI. You can boot up the UI at first to see what are their functionalities.

Your goals

Your goal is to re-implement this forum happ, one step at a time.

To do that, go into EXERCISES.md and follow its instructions. Have fun!

Environment Setup

1. Install the holochain dev environment: https://developer.holochain.org/docs/install/

2. Clone this repo and cd inside of it.

3. Enter the nix shell by running this in the root folder of the repository:

nix develop
npm install

This will install all the needed dependencies in your local environment, including holochain, hc and npm.

Run all the other instructions in this README from inside this nix develop shell, otherwise they won't work.

Starting an agent

Start a forum agent with:

npm start

You should be able to see all the posts that other participants have created in this DHT.

Bootstrapping a network

Create a whole network of nodes connected to each other and their respective UIs with.

AGENTS=3 npm run network 

Substitute the "3" for the number of nodes that you want to bootstrap in your network.

This will also bring up the Holochain Playground for advanced introspection of the conductors.

Documentation

This repository is using this tooling:

• NPM Workspaces: npm v7's built-in monorepo capabilities.
• hc: Holochain CLI to easily manage Holochain development instances.
• @holochain/tryorama: test framework.
• @holochain/client: client library to connect to Holochain from the UI.
• @holochain-playground/cli: introspection tooling to understand what's going on in the Holochain nodes.
