    Hazel

    Hazel

    Lightweight update server for Electron apps

    This project lets you deploy an update server for Electron apps with ease: You only need to click a button. The result will be faster and more lightweight than any other solution out there! Once it's deployed, paste the deployment address into your code (please keep in mind that updates should only occur in the production version of the app, not while developing). Since Hazel routes all the traffic for downloading the actual application files to GitHub Releases, you can use their API to determine the download count for a certain release. Display an overview page showing the cached repository with the different available platforms and file sizes. Links to the repo, releases, specific cached version and direct downloads for each platform are present. Automatically detects the platform/OS of the visitor by parsing the user agent and then downloads the appropriate copy of your application.
