Omni-file is a comprehensive file information extractor that provides language, icon, type, and MIME information for any file based on its name or extension. With **over 1000 icons**, support for **more than 700 programming languages**, and only **79.4 kB gzipped**, it's both **powerful and lightweight**!
> It leverages [GitHub Linguist](https://github.com/github/linguist) data and [Material Icon Theme](https://github.com/PKief/vscode-material-icon-theme) for up-to-date and accurate file type detection and icons. The data is regularly updated to ensure the latest language and icon information.

### Examples of `getIcon`
```typescript
import { getIcon } from "omni-file";
console.log(getIcon("example.js")); // Output: 'javascript'
console.log(getIcon("styles.css")); // Output: 'css'
console.log(getIcon("data.json")); // Output: 'json'
console.log(getIcon("package.json")); // Output: 'nodejs'
console.log(getIcon("Dockerfile")); // Output: 'docker'
console.log(getIcon(".gitignore")); // Output: 'git'
console.log(getIcon("src", { isFolder: true })); // Output: 'folder-src'
console.log(getIcon("node_modules", { isFolder: true })); // Output: 'folder-node'
console.log(getIcon("tests", { isFolder: true, isExpanded: true })); // Output: 'folder-test-open'
console.log(getIcon("vercel.json", { isLight: true })); // Output: 'vercel_light'
console.log(getIcon("example.test.js")); // Output: 'test-js'
console.log(getIcon("component.spec.ts")); // Output: 'test-ts'
console.log(getIcon(path.join("src", "components", "Button.tsx"))); // Output: 'react_ts'
console.log(getIcon(path.join("tests", "unit", "utils.test.js"))); // Output: 'test-js'
console.log(getIcon(".eslintrc.json")); // Output: 'eslint'
console.log(getIcon(".prettierrc")); // Output: 'prettier'
console.log(getIcon("tsconfig.json")); // Output: 'tsconfig'
console.log(getIcon("README.md")); // Output: 'readme'
console.log(getIcon("readme.md")); // Output: 'readme'
console.log(getIcon("DockerFile")); // Output: 'docker'
console.log(getIcon("dockerfile")); // Output: 'docker'
```
### Example with language
```typescript
import { getLanguage } from "omni-file";
console.log(getLanguage("folder/example.ts"));
```
**Output:**
```json
{
"type": "programming",
"color": "#3178c6",
"aliases": ["ts"],
"interpreters": ["deno", "ts-node", "tsx"],
"extensions": [".ts", ".cts", ".mts"],
"tm_scope": "source.ts",
"ace_mode": "typescript",
"codemirror_mode": "javascript",
"codemirror_mime_type": "application/typescript",
"language_id": 378,
"name": "TypeScript",
"icons": ["typescript", "javascript"]
}
```
> Note that you can also get icons from `getLanguage` by using `getLanguage(filename)?.icons` but the answer may be less accurate. (folder icons are not included this way)
### Example implementation of `getIcon`
```tsx
import { getIcon } from "omni-file";
const icon = getIcon("folder/example.ts"); // "typescript"
const svgUrl = `node_modules/omni-file/icons/${icon}.svg`;
<img src={svgUrl} alt={icon} />;
```
**Output:**
<img src="https://github.com/CodyAdam/omni-file/raw/main/public/icons/typescript.svg" alt="TypeScript" width="64" height="64">
### Example using raw data
```tsx
import { languages, icons } from "omni-file";
console.log(languages["JavaScript"].extensions); // -> [ ".js",".cjs",".es",".jsm", ... ]
console.log(icons.fileExtensions["js"]); // -> "javascript"
```

## Icon Themes
Omni-file provides two icon sets:
1. **Dark Theme**: Default icon set for dark-themed environments.
2. **Light Theme**: Optimized icon set for light-themed environments. Note that this set has fewer icons then the dark theme but the function will fallback to the dark theme if the light themed icon is not found.
You can switch between these themes based on your application's needs:
```typescript
import { getIcon, IconTheme } from "omni-file";
const darkIcon = getIcon("example.ts", { isLight: false });
const lightIcon = getIcon("example.ts", { isLight: true });
```
