Intlayer Content Nodes

Define rich and dynamic content using Intlayer functions. Use the reference below for each node type.

Translation (t)

Define multilingual content mapped to locales.

Doc

import { t } from "intlayer";

const content = t({
  en: "Hello",
  fr: "Bonjour",
  es: "Hola",
});

Find locales to declare in config file. Supported configuration files:

• intlayer.config.{ts|js|json|json5|jsonc|cjs|mjs}
• .intlayerrc

Enumeration (enu)

Map content to specific keys, numbers, or ranges (useful for pluralization).

Doc

import { enu } from "intlayer";

const carCount = enu({
  "0": "No cars",
  "1": "One car",
  ">1": "Multiple cars",
  fallback: "Unknown amount",
});

Condition (cond)

Define content based on a boolean condition.

Doc

import { cond } from "intlayer";

const isLoggedIn = cond({
  true: "Welcome back!",
  false: "Please log in",
  fallback: "Status unknown", // Optional
});

Markdown (md)

Define rich text using Markdown syntax.

Doc

import { md } from "intlayer";

const article = md("# Title\n\nSome **bold** text.");

HTML (html)

Define HTML content, optionally with custom components.

Doc

import { html } from "intlayer";

const richText = html("<p>Hello <strong>World</strong></p>");

Nesting (nest)

Reuse content from another dictionary.

Doc

import { nest } from "intlayer";

// Reference entire dictionary
const fullRef = nest("other_dictionary_key");

// Reference specific path
const partialRef = nest("other_dictionary_key", "path.to.value");

Function Fetching

Execute logic to generate content (synchronous or asynchronous).

Doc

const computed = () => `Current time: ${new Date().toISOString()}`;

const fetched = async () => {
  const data = await fetch("/api/data").then((res) => res.json());
  return data.message;
};

Insertion (insert)

Define dynamic content with variables.

Doc

import { insert } from "intlayer";

const welcome = insert("Hello {{name}}!");

File (file)

Reference external files as content.

Doc

import { file } from "intlayer";

const myFile = file("./path/to/file.txt");

Gender (gender)

Define content based on gender (‘male’, ‘female’, etc.).

Doc

import { gender } from "intlayer";

const greeting = gender({
  male: "Welcome sir",
  female: "Welcome madam",
  fallback: "Welcome",
});

Example Directory Structure (react)

src/
├── components/
│   ├── MyComponent/
│   │   ├── index.content.ts          # Content declaration
│   │   └── index.tsx                 # Component
│   ├── myOtherComponent.content.ts   # Content declaration
│   └── MyOtherComponent.tsx          # Component

Content Templates

TypeScript (.content.ts)

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

const content = {
  key: "my-component-key",
  content: {
    title: "...",
  },
} satisfies Dictionary;

export default content;

TypeScript with React (.content.tsx)

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

const content = {
  key: "my-component-key",
  content: {
    title: <>My React Node</>,
  },
} satisfies Dictionary;

export default content;

{
  "key": "my-component-key",
  "content": {
    "title": "..."
  }
}

import { t } from "intlayer";

/** @type {import('intlayer').Dictionary} **/
const content = {
  key: "my-component-key",
  content: {
    title: "...",
  },
};

export default content;

Content declaration combination

Nodes can be imbricated for complex logic.

import {
  cond,
  enu,
  file,
  gender,
  insert,
  html,
  md,
  nest,
  t,
  type Dictionary,

      "0": "No cars",
      "1": "One car",
      ">19": "Many cars",
      ">5": "Some cars", // Will never will triggered, because >5 is included between 1 and >19
      fallback: "Fallback value", // Optional but avoid undefined type
    }),

Type validation of dictionary

Dictionary<{ title: string; description?: string }>; // Generic describing content type for formatted data (metadata, etc)

Key Dictionary Fields for AI Management

Core Metadata

• key: The identifier for the dictionary (e.g., about-page-meta). AI can ensure consistent naming conventions.
• title: A human-readable name for identification in the CMS or editor.
• description: Provides context for the dictionary. AI uses this to understand the purpose and generate better translations or content.
• tags: Categorization strings (e.g., metadata, SEO) to help organize and filter dictionaries.

Content & Localization

• locale: Specifies the language of the content for (per-locale file)[references/concept_per-locale-file.md]
• contentAutoTransformation: A toggle to automatically convert raw strings into specialized formats like Markdown, HTML, or Insertions (variables).
• fill: An instruction indicating whether the dictionary should be automatically populated by AI/automation tools.

Behaviorals Settings

• priority: A numeric value used to resolve conflicts during merge of dictionaries under a same key.
• importMode: Defines how content is loaded (static, dynamic, or live). AI can recommend the best mode based on performance needs.
• location: Controls CMS synchronization (hybrid, remote, local). AI can manage where the source of truth resides.
• schema: string that use zod schema declared in config file to validate data
