intlayer-preact

A guide for adding multiple languages to Preact applications, which are web apps built with the Preact user-interface library. It keeps each component's translated text beside that component.

In plain words
What is it for?
Use it to configure Intlayer in Preact, declare translations, create translated components, and read their content with the useIntlayer hook.
Why use it?
It avoids putting all translations into one large, difficult-to-maintain file and shows components how to load their own language-specific content.

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

intlayer-preact 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 2d 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.

What it actually says

Intlayer Preact Usage

Core Philosophy

Intlayer promotes Component-Level Content Declaration. Instead of a massive global translation file, content is declared in *.content.ts files adjacent to the Preact components that use them.

Workflow

To create a translated component, you need two files:

  1. Declaration: A content file (e.g., myComponent.content.ts) defining the dictionary.
  2. Implementation: A Preact component (e.g., MyComponent.tsx) using the useIntlayer hook.

Declare Content

Create a content file using t() for translations. File: src/components/MyComponent/myComponent.content.ts

import { t, type Dictionary } from "intlayer";

const content = {
  // The 'key' must be unique and matches what you pass to useIntlayer()
  key: "my-component",
  content: {
    text: t({
      en: "Welcome",
      fr: "Bienvenue",
      es: "Hola",
    }),
  },
} satisfies Dictionary;

export default content;

Setup

useIntlayer Hook

import { useIntlayer } from "preact-intlayer";

const MyComponent = () => {
  const content = useIntlayer("my-component");

  return (
    <div>
      <h1>
        {/* Return content */}
        {content.text}
      </h1>
      {/* Return string (.value) */}
      <img src={content.text.value} alt={content.text.value} />
    </div>
  );
};

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
