Structured metadata for programming languages, packaged as a typed, tree-shakeable TypeScript library.
code-languages is useful when you need a small source of truth for language names, slugs, file extensions, release metadata, websites, paradigms, logos, and reference colors in developer tools, docs sites, learning platforms, or editor-like interfaces.
- TypeScript-first data model
- Zero runtime dependencies
- ESM and CommonJS builds
- Subpath imports for per-language usage
- Tree-shakeable exports
- Localized content in English, Spanish, Italian, and French
- Works in Node.js and modern bundlers
npm install code-languagesImport only the language metadata you need:
import { typescript } from "code-languages/typescript";
import { localizeLanguage } from "code-languages/i18n";
const localized = localizeLanguage(typescript, "en");
console.log(localized.name);
console.log(localized.description);
console.log(typescript.extensions);
console.log(typescript.paradigms);Import multiple languages:
import { abap } from "code-languages/abap";
import { actionscript } from "code-languages/actionscript";
console.log(abap.version);
console.log(actionscript.extensions);Import from the package root when bundle size is not a concern:
import {
abap,
actionscript,
} from "code-languages";
console.log(localizeLanguage(abap).description);
console.log(localizeLanguage(actionscript, "es").description);Every language object satisfies the Language interface:
export type BaseLocale = "en" | "es" | "it" | "fr" | "de" | "pt";
export type Locale = BaseLocale | `${BaseLocale}-${string}` | string;
export interface LanguageContent {
name: string;
description: string;
longDescription: string;
}
export interface Language {
slug: string;
publishedDate: string;
extensions: string[];
author: string;
website: string;
paradigms: string[];
tooling?: {
runtimes?: string[];
packageManagers?: string[];
ecosystems?: string[];
};
version: string;
logo: string;
color: `#${string}`;
i18n: {
en: LanguageContent;
es?: LanguageContent;
it?: LanguageContent;
fr?: LanguageContent;
de?: LanguageContent;
pt?: LanguageContent;
};
}Use the fluent API when you want one entry point for localization, dynamic loading, and filename detection:
import { api } from "code-languages/api";
const astro = api.language("astro").locale("es-PE").get();
const vue = await api.language("vue").locale("en-US").load();
const detected = api.detect("src/App.vue").locale("es").get();
const ambiguous = await api.detectAll("include/config.h").locale("en").load();
console.log(astro?.resolvedLocale); // "es"
console.log(vue?.slug); // "vue"
console.log(detected?.name); // "Vue"
console.log(ambiguous.map((language) => language.slug)); // ["c", "cpp"]api.language(...) normalizes lookup values to the package slug format, so inputs
such as "Visual Basic" and "Jupyter Notebook!" resolve to visual-basic and
jupyter-notebook.
get() reads from the bundled in-memory catalog. load() uses explicit dynamic
imports so bundlers can lazy-load individual language modules when the consumer
build supports code splitting.
Use localizeLanguage to read localized display content with English fallback:
import { json } from "code-languages/json";
import { localizeLanguage } from "code-languages/i18n";
const language = localizeLanguage(json, "es-PE");
console.log(language.name);
console.log(language.longDescription);
console.log(language.resolvedLocale); // "es"localizeLanguage resolves locales in this order:
- Exact locale, for example
es. - Base language from a regional locale, for example
es-PE->es. - English fallback, for example
ja-JP->en.
English, Spanish, Italian, French, German, and Portuguese are supported base locales.
The current Italian, French, German, and Portuguese translations were initially
generated with translategemma:4b; translation reviews and corrections are welcome.
Use detectLanguage or detectLanguages to infer languages from filenames:
import { detectLanguage, detectLanguages } from "code-languages/detect";
console.log(detectLanguage("src/index.ts")?.slug); // "typescript"
console.log(detectLanguage("Dockerfile")?.slug); // "dockerfile"
console.log(detectLanguages("include/config.h").map((language) => language.slug)); // ["c", "cpp"]Use detectLanguageSlug or detectLanguageSlugs when you only need the slug
and want to avoid importing the full language catalog:
import { detectLanguageSlug, detectLanguageSlugs } from "code-languages/detect-slugs";
console.log(detectLanguageSlug("src/index.ts")); // "typescript"
console.log(detectLanguageSlugs("include/config.h")); // ["c", "cpp"]Use detectProjectLanguages to summarize a project file list by detected language:
import { detectProjectLanguages } from "code-languages/detect-slugs";
const files = ["src/index.ts", "src/app.ts", "README.md", "styles/main.css", "LICENSE"];
console.log(detectProjectLanguages(files));
// [
// { slug: "typescript", files: 2 },
// { slug: "css", files: 1 },
// { slug: "markdown", files: 1 }
// ]The catalog currently includes 203 language entries. Each row can be imported directly from its package subpath.
