  • GitHub repo Electron

    :electron: Build cross-platform desktop apps with JavaScript, HTML, and CSS

    Project mention: Ask HN: What does the future hold for Electron? | news.ycombinator.com | 2021-10-15

    Microsoft owns Github. Github maintains Electron. Microsoft are moving Teams to use WebView2, sharing a single Chromium instance for all apps, reducing memory usage, which is the most common complaint for Electron.

    This architecture has been obvious to everyone for a long time. Every Electron app could essentially be a webpage but with enhanced native API access.

    Electron's future seems bleak. ESM support hasn't materialized (https://github.com/electron/electron/issues/21457). WebView2 will not be available on macOS until late 2022 [it seems](https://github.com/MicrosoftEdge/WebView2Feedback/issues/645#issuecomment-921551618).

    Seems we are in one of these awkward transition periods, where you are forced to start a project on technology that you know will be deprecated in the near future sigh.

    Anyone have insight/predictions?

    To practice, I worked on refactoring my dodo-SSG project in a new branch that I called refactoring. I started by fixing the code format from previous contributions using prettier. I then changed the code to get rid of global variables. To do that, I had to split up some code into separate smaller functions. At each of these steps, I created a new commit to make sure I could easily go back to the previous version if anything broke (And things broke a lot while doing this!).

    For my last two personal websites I used Svelte (not Sapper or SvelteKit), married up with Page.js for client-side routing and Tailwind (+ PostCSS) for styling stuff. The sites are hosted from AWS S3 buckets with CloudFront for the CMS stuff. And because these projects are entirely personal I've not had to do a lot of worrying about the toolchain: both codebases are in git repositories; testing (when I bother) is manual; building/deployment are handled using various shell scripts.
