templui

templui is a skill for Claude Code, Codex from gopherguides/gopher-ai. It costs 120 tokens per session (920 once invoked), scanned A, original, MIT.

A set of interface patterns for templUI, a component library for Go web applications, using ordinary browser JavaScript instead of a JavaScript framework.

In plain words
What is it for?
Use it when building Go and Templ web pages with dropdowns, dialogs, tabs, sidebars, popovers, accordions, forms, or partial page updates.
Why use it?
It helps keep templUI components compatible with their intended setup and avoids adding unnecessary frontend framework dependencies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

templui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

templUI Best Practices

Apply templUI patterns when building Go/Templ web applications.

CRITICAL: templUI Uses Vanilla JavaScript (Zero JS Frameworks)

Per templui.io: "Zero JS frameworks — Just vanilla. Just fast." templUI components use vanilla JavaScript via Script() templates for all interactivity (popovers, dropdowns, dialogs, tabs, etc.). They do NOT depend on Alpine.js, React, Vue, or any other framework.

Earlier versions of templUI integrated with Alpine.js. That dependency has been removed. If you find documentation or code referencing x-data/x-show/x-if directives inside templUI components, it's stale.

The Frontend Stack

Tool Purpose Use For
templUI Pre-built UI components (vanilla JS) Dropdowns, dialogs, tabs, sidebars, popovers, accordions
HTMX Server-driven interactions AJAX, form submissions, partial page updates, live search
Alpine.js (optional) Lightweight client-side state Toggles, animations, client-side filtering, transitions — used alongside templUI, not as an integration. Skip if you don't need a reactive state layer beyond what HTMX + Script() provide.
Floating UI Positioning primitive (used internally by templUI) Tooltips, popovers, dropdowns — usually transparent to users

Reference Files

Read the relevant file for detailed patterns, code examples, and troubleshooting:

htmx-alpine-integration.md — HTMX + Alpine.js (optional, separate from templUI)

For apps that choose to add Alpine.js as a client-side state layer alongside templUI. Read only when Alpine is actually in use. Covers: when to use HTMX vs Alpine vs combined, Alpine-Morph extension for state preservation across swaps, htmx.process() for Alpine conditionals, triggering HTMX from Alpine. Skip if your app uses templUI + HTMX + Script() without Alpine — that's templUI's recommended setup.

templ-interpolation.md — CRITICAL: Templ Interpolation in JavaScript

Go expressions { value } do NOT interpolate inside <script> tags. Five patterns to solve this:

  1. Data attributes (recommended) — data-* attrs + this.dataset
  2. templ.JSFuncCall — auto JSON-encodes, prevents XSS
  3. Double braces{{ value }} inside <script> tags
  4. templ.JSONString — complex structs/maps via attributes or templ.JSONScript
  5. templ.OnceHandle — ensures scripts render once in loops

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

templui is a skill published in the GitHub repository gopherguides/gopher-ai (21 stars, last pushed today), licensed MIT. It adds 120 tokens to every session and 920 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
