Process: Renderer

Methods

The webUtils module has the following methods:

webUtils.getPathForFile(file)

• file File - A web File object.

Returns string - The file system path that this File object points to. In the case where the object passed in is not a File object an exception is thrown. In the case where the File object passed in was constructed in JS and is not backed by a file on disk an empty string is returned.

This method superseded the previous augmentation to the File object with the path property. An example is included below.

// Before
const oldPath = document.querySelector('input').files[0].path

// After
const { webUtils } = require('electron')
const newPath = webUtils.getPathForFile(document.querySelector('input').files[0])
