注目すべき変更​

ハイライト​

  • Added a new top-level webUtils module, a renderer process module that provides a utility layer to interact with Web API objects. The first available API in the module is webUtils.getPathForFile. Electron's previous File.path augmentation was a deviation from web standards; this new API is more in line with current web standards behavior.

累積的変更​

Electron 29 upgrades Chromium from 120.0.6099.56 to 122.0.6261.39, Node from 18.18.2 to 20.9.0, and V8 from 12.0 to 12.2.

新機能​

  • Added new webUtils module, a utility layer to interact with Web API objects, to replace File.path augmentation. #38776
  • Added net module to utility process. #40890
  • Added a new Electron Fuse, grantFileProtocolExtraPrivileges, that opts the file:// protocol into more secure and restrictive behaviour that matches Chromium. #40372
  • Added an option in protocol.registerSchemesAsPrivileged to allow V8 code cache in custom schemes. #40544
  • Migrated app.{set|get}LoginItemSettings(settings) to use Apple's new recommended underlying framework on macOS 13.0+. #37244

破壊的変更​

Behavior Changed: ipcRenderer can no longer be sent over the contextBridge​

Attempting to send the entire ipcRenderer module as an object over the contextBridge will now result in an empty object on the receiving side of the bridge. This change was made to remove / mitigate a security footgun. You should not directly expose ipcRenderer or its methods over the bridge. Instead, provide a safe wrapper like below:

contextBridge.exposeInMainWorld('app', {
  onEvent: (cb) => ipcRenderer.on('foo', (e, ...args) => cb(args)),
});

Removed: renderer-process-crashed event on app​

The renderer-process-crashed event on app has been removed. Use the new render-process-gone event instead.

// Removed
app.on('renderer-process-crashed', (event, webContents, killed) => {
  /* ... */
});

// Replace with
app.on('render-process-gone', (event, webContents, details) => {
  /* ... */
});

Removed: crashed event on WebContents and <webview>​

The crashed events on WebContents and <webview> have been removed. Use the new render-process-gone event instead.

// Removed
win.webContents.on('crashed', (event, killed) => {
  /* ... */
});
webview.addEventListener('crashed', (event) => {
  /* ... */
});

// Replace with
win.webContents.on('render-process-gone', (event, details) => {
  /* ... */
});
webview.addEventListener('render-process-gone', (event) => {
  /* ... */
});

Removed: gpu-process-crashed event on app​

The gpu-process-crashed event on app has been removed. Use the new child-process-gone event instead.

// Removed
app.on('gpu-process-crashed', (event, killed) => {
  /* ... */
});

// Replace with
app.on('child-process-gone', (event, details) => {
  /* ... */
});

次回予告​

Did you know that Electron recently added a community Request for Comments (RFC) process? If you want to add a feature to the framework, RFCs can be a useful tool to start a dialogue with maintainers on its design. You can also see upcoming changes being discussed in the Pull Requests. To learn more, check out our Introducing electron/rfcs blog post, or check out the README of the electron/rfcs repository directly.

短期的には、Chromium、Node、V8 といった Electron を構成する主要コンポーネントの開発に遅れないでチームが注力し続けるでしょう。
