webUtils
A utility layer to interact with Web API objects (Files, Blobs, etc.)
Process: Renderer
Methoden
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This method superseded the previous augmentation to the File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 (renderer)
const oldPath = document.querySelector('input[type=file]').files[0].path
// After
// Renderer:
const file = document.querySelector('input[type=file]').files[0]
electronApi.doSomethingWithFile(file)
// Preload script:
const { contextBridge, webUtils } = require('electron')
contextBridge.exposeInMainWorld('electronApi', {
doSomethingWithFile (file) {
const path = webUtils.getPathForFile(file)
// Do something with the path, e.g., send it over IPC to the main process.
// It's best not to expose the full file path to the web content if possible.
}
