$3

`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"],

"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)

$3

`tsx
import { getIcon } from "omni-file";

const icon = getIcon("folder/example.ts"); // "typescript"
const svgUrl = node_modules/omni-file/icons/${icon}.svg;

;
`

Output:

$3

`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 });
`
