nomadnet-rs

Rust library for NomadNet node hosting and browsing over the Reticulum Network Stack.

Zero-application-logic dependencies — works with any RNS-based project.

Features

• Node hosting — serve .mu (Micron) pages and binary files over RNS Link request/response
• Node discovery — track announced NomadNet nodes from RNS transport
• Node browsing — fetch pages and files from remote NomadNet nodes via [NomadBrowser]
• Micron markup — fluent builder for NomadNet page content, including tables and partials

nomadnet-serve Binary

The nomadnet-serve binary serves static .mu files from a folder as a NomadNet node. Enable the serve feature:

[dependencies]
nomadnet-rs = { version = "0.1", features = ["serve"] }

# Install from crates.io
cargo install nomadnet-rs --features serve --bin nomadnet-serve

# Run
nomadnet-serve -p ./my-pages --rns-config ~/.config/reticulum/config --watch

Drop .mu files in the pages directory. If no index.mu exists, one is auto-generated listing all available pages. Use --files-dir to serve binary files alongside pages.

Quick Start (Library)

[dependencies]
nomadnet-rs = "0.1"
rns-core = "0.1"
rns-crypto = "0.1"
rns-net = "0.5"

Serve pages and files

use std::sync::Arc;
use nomadnet_rs::{NomadNode, NodeConfig, PageCache, FileCache, MicronBuilder};
use rns_net::RnsNode;

let pages = ["/page/index.mu", "/page/about.mu"];
let files = ["/file/readme.txt", "/file/data.json"];
let nomad = NomadNode::new(node.clone(), config, &pages, &files)?;
let page_cache = nomad.page_cache();
let file_cache = nomad.file_cache();

let mut page = MicronBuilder::new();
page.heading(1, "Hello from NomadNet");
page.text("Served via Reticulum.");
page_cache.set("/page/index.mu", page.build().into_bytes());

Build a Micron page

use nomadnet_rs::{MicronBuilder, TableAlign};

let mut page = MicronBuilder::new();
page.cache_directive(300);
page.heading(1, "My Page");
page.divider();
page.bold("Status: ");
page.text("online");
page.blank_line();

// Table
page.table_start(Some(TableAlign::Center), Some(40));
page.table_row(&["Name", "Value"]);
page.table_row(&["----", "-----"]);
page.table_row(&["Users", "5"]);
page.table_end();

page.blank_line();

// Auto-updating partial
page.partial("aabbccdd:/page/stats.mu", Some(10.0), "channel=general");

// Truecolor
page.truecolor_fg("ff5500");
page.text("Bright orange text");
page.reset_fg();

Discover nodes

use nomadnet_rs::{NomadDirectory, directory::is_nomadnet_announce};

let mut directory = NomadDirectory::new();

// In your RNS callback:
fn on_announce(&mut self, announced: AnnouncedIdentity) {
    if is_nomadnet_announce(&announced) {
        directory.handle_announce(&announced);
    }
}

Browse remote nodes

use nomadnet_rs::{NomadBrowser, BrowseEvent};

let browser = NomadBrowser::new();
let mut events = browser.events();

browser.fetch(&node, dest_hash, sig_pub, "/page/index.mu")?;

// Fetch with request data
browser.fetch_with_data(&node, dest_hash, sig_pub, "/page/search.mu", b"query=hello")?;

// Fetch a file
browser.fetch_file(&node, dest_hash, sig_pub, "/file/readme.txt", None)?;

// In your event loop:
match events.recv().await {
    Some(BrowseEvent::PageReceived { content, .. }) => { /* handle page */ },
    Some(BrowseEvent::FileReceived { content, path, .. }) => { /* handle file */ },
    _ => {}
}

Modules

Architecture Notes

• NomadNet uses RNS Link request/response (not LXMF messaging) on aspect nomadnetwork.node
• Page handlers run synchronously on the RNS driver thread — use PageCache/FileCache to decouple async page generation from sync request handling
• A built-in /page/test.mu handler is always registered for connectivity debugging
• Cache misses for pages return auto-generated 404 pages; file cache misses return no response
• NomadBrowser distinguishes page vs file responses via the path prefix (/page/ vs /file/)
• URL field parsing (url\field=val) is supported via parse_url_fields()andfetch_with_data()`
