Nowadays it’s unlikely that you do not know what Electron is, but we will explain to you briefly. Electron is a framework that uses web technologies to create desktop applications with JavaScript, HTML, and CSS. Along with a mix of NodeJS.

Many applications that are already part of our daily lives, such as Visual Studio Code or Twitch have been created with this framework. This shows us that it is a very reliable option to make our desktop applications.

Electron 9.0 features

With this release, Electron also leaves the support for branch 6. So you were still using it, you have to upgrade quickly.

The most important new feature of this new version is that they now use Chromium 83, NodeJS 12.14.1, and V8.3 so you can expect internal improvements of many kinds.

Moreover, Electron 9.0 restores the support for pdfium-based PDF viewer. A feature that will make life easier for many developers.

Also it has to be said that this new version has taken care of the performance in Linux. This is something that applications created with Electron suffer. Well, from now on applications created with Electron 9 should go much better.

Others important news are:

• Removed deprecated .getWebContents().
• Removed the deprecated ‘setLayoutZoomLevelLimits’ method.
• IPC between main and renderer processes now uses the Structured Clone Algorithm.
• Multiple improvements to the spellchecker feature.
