Electron 31 Removes WebSQL and Adds the File System API

Electron 31 arrives

Electron 31.0.0 was released on June 11, 2024, upgrading Chromium from 124 to 126.0.6478.36, Node.js from 20.11.1 to 20.14.0 and V8 from 12.4 to 12.6. It brought a mix of new web platform support and removals that followed upstream Chromium.

The File System API and WebSQL removal

Electron 31 implemented support for the web standard File System API, giving apps a standardized way to read and write local files. At the same time it removed WebSQL support, following Chromium's upstream removal, which transitioned WebSQL to Android only.

Certificates and window handling

The release added support for Node's NODE_EXTRA_CA_CERTS environment variable, letting apps supply extra trusted certificate authorities. It extended WebContentsView to accept a pre-existing WebContents instance, and extended webContents.setWindowOpenHandler to support manual creation of a BrowserWindow.

Behavior changes

nativeImage.toDataURL now preserves PNG colorspace data, and win.flashFrame(true) flashes the dock icon continuously on macOS until flashFrame(false) is called, bringing macOS to parity with Windows and Linux. Electron 28 reached end-of-support with this release under the project's support policy.
