I need one help. I need to fetch what the file type should be from the file content only using Node.js. I am exaplining the scenario below.
Lets say I have some content like below.
let fileContent = "The textContent property sets or returns the text content of the specified node, and all its descendants."
If we can see here the variable fileContent
has some text data and I want to write this data into one file. So for that I need to create the file with proper extension like abc.txt
. Similarly If fileContent
has some json
data then I will create the file like abc.json
and write the value inside it.
So here I need to fetch what should be the type
of file from this content only using Node.js
. If anybody has solution for this will be great help.
You can use popular file-type package for this. You can send buffer/file/stream/blob as an input and get file type as an output.
const FileType = require('file-type');
...
const { ext, mime } = await FileType.fromBuffer(your_data);
