The vendored icons

What icons devpage can draw — the Lucide set, plus GitHub's mark — where they came from, their versions and licences, how devpage draws them, and how to upgrade them. It is a mechanism page under the viewer, for someone about to replace the set; using icons in a site's navbar is in Organizing navigation.

What is in the repository

File What it is
assets/vendor/lucide.json Every Lucide icon — 1,877 of them — from lucide-static 1.55.0 (published 2026-10-10): its icon-nodes.json, minified. Each icon is a list of SVG elements on a 24 × 24 grid, drawn with strokes.
assets/vendor/lucide.LICENSE Lucide's licence: ISC, with the MIT notice for the icons derived from Feather.
src/icons.rs GitHub's mark, one filled path, from Simple Icons 16.34.0 under CC0 1.0 — Lucide carries no brand marks.

How devpage uses them

src/icons.rs compiles lucide.json into the binary with include_str! and reads it once, on first use. An icon is drawn on the server, as inline SVG in the page — <svg class="icon">, in the text color (currentColor) — so a page carries only the icons it shows and they follow the theme. A name the set doesn't have is a problem (Checking links). devpage draws icons in a site's navbar and in the theme selector (moon and sun, and menu and chevron-down for the navbar's own controls).

Upgrading them

  1. Fetch the icons and the licence Pick a lucide-static version published at least two weeks ago.

    curl -so nodes.json https://cdn.jsdelivr.net/npm/lucide-static@<version>/icon-nodes.json
curl -so assets/vendor/lucide.LICENSE https://cdn.jsdelivr.net/npm/lucide-static@<version>/LICENSE
python3 -c 'import json; json.dump(json.load(open("nodes.json")), open("assets/vendor/lucide.json", "w"), separators=(",", ":"))'

  2. Check every icon devpage names still exists Lucide renames icons now and then; the icons test names devpage's own, and the docs check covers the docs' navbars.

    $ cargo test $ cargo run -- check docs

  3. Update this page The version, count and date.

GitHub's mark changes rarely; to replace it, copy the d of the path in Simple Icons' icons/github.svg into BRANDS in src/icons.rs.
