The Bun.file() function accepts a path and returns a BunFile instance. The BunFile class extends Blob, so use the .type property to read the MIME type. 
const file = Bun.file("./package.json"); file.type; // application/json  const file = Bun.file("./index.html"); file.type; // text/html  const file = Bun.file("./image.png"); file.type; // image/png
Refer to API > File I/O for more information on working with BunFile.
