💁File Info
Use file info API to get metadata of your file stored at Lighthouse.
const fileInfo = async() => {
/*
@param {string} cid - cid of file.
*/
const cid = "QmeMsykMDyD76zpAbinCy1cjb1KL6CVNBfB44am15U1XHh"
const fileInfo = await lighthouse.getFileInfo(cid)
/* Sample Response

data: {
fileSizeInBytes: '95077',
cid: 'QmeMsykMDyD76zpAbinCy1cjb1KL6CVNBfB44am15U1XHh',
encryption: false,
fileName: 'itachi.jpg',
mimeType: 'image/jpeg',
txHash: ''
}
}
