contacts

What is contacts and what is it for?

contacts is a small reusable Holochain module that lets an application keep a list of the other agents it has added or blocked. It is distributed as a zome and a JavaScript package of Web Components, so other Holochain projects can include it rather than writing their own contact handling.

contacts belongs to holochain-open-dev, a community organisation that builds and shares reusable open-source building blocks for Holochain applications. Its own documentation — which describes the project as of its most recent update — presents contacts as one of those building blocks rather than as a finished application: a module other Holochain projects can pick up and include in their own DNA. Nothing in the README records when or why the work was started.

In plain terms, the module keeps a list of the other agents a Holochain application has added or blocked — the contacts an app decides to remember about. It is deliberately small and assumes as little as possible about the DNA it is dropped into, so a project can add contact handling without adopting a larger framework. The same work is also packaged as an npm module of browser-friendly Web Components for the interface side.

A developer building a Holochain app that needs to track which agents it trusts or has blocked can add contacts as a dependency, register it in the DNA's dna.yaml, and compile, following the numbered steps in the README. That README is the fullest maintainer documentation reachable today; it marks its 'Including the UI' section as still to be written, so the JavaScript package is described but has no documented usage.
