When attempting to implement gray-matter
in an electron application, I encountered the error message
utils.js:36 Uncaught ReferenceError: Buffer is not defined
. Is there a method or workaround available to utilize Buffer

Although this information may be outdated for the original poster, I wanted to share my solution for those who come across a similar issue like I did.
In my project, I encountered a problem with exposing NodeJS's Buffer object for my Electron front-end (using React). The easiest way I found was by utilizing an Electron preload script.
Within the preload.js file:
const { contextBridge } = require('electron');
contextBridge.exposeInMainWorld('nodeAPI', {
createBuffer: (data) => Buffer.from(data)
});
Then, in your front end code, you can reference it as follows:
const buffer = window.nodeAPI.createBuffer(event.target.result);
If it helps someone else, here is a comprehensive example of using this method to retrieve a file from the frontend and pass it to a backend method for database storage:
const uploadFile = async (fileName, file) => {
if(file){
const reader = new FileReader();
reader.onload = async (event) => {
const buffer = window.nodeAPI.createBuffer(event.target.result);
try{
await window.electronAPI.addFile({
fileName: fileName,
file: buffer
});
}catch(err){
console.error('Error adding file: ', err);
}
};
reader.readAsArrayBuffer(file);
}else{
alert('Error saving file.');
}
};
