It also helps prevent remote content to directly access desktop features using a feature called WebView Element which creates a fresh Chromium renderer process and assigns rendering of content for its hosting renderer. Electron functions on Chromium's multi-process model, with each Slack team signed into a separate process and memory space. The new desktop app is now based on an ES6 + async/await React application is currently being moved gradually to TypeScript.
But it was difficult to upgrade with new features only available to Apple's WKWebView and moving to this view called for a total application rewrite.Įlectron brings together Chromium's rendering engine with the Node.js runtime and module system. Slack's original desktop app was written using the MacGap v1 framework using WebView to host web content within the native app frame. Instead of adopting a complete-in-box approach taken by other apps, Slack prefers a hybrid approach where some of the assets are loaded as part of the app, while others are made available remotely. It was built using Electron for a faster, frameless look with a host of background improvements for a superior Slack experience. You’ll modify the code so that you can inject the first piece of dynamic data.Slack's new desktop application was launched for macOS. So now, you’ll use Mustache, a simple but flexible templating language. A better approach is to treat the HTML as a template that you can fill in with relevant data. Generating invoices won’t be useful if you need to modify HTML every time you need to issue an invoice. Great! You can see that the HTML file was correctly converted to PDF. Now, when you run this script using node generate.js, you can open the invoice.pdf file and see the result: The last step (line 25) saves the generation result on disk in the invoice.pdf file.
After that, you’re packaging all of this data in a multipart request (lines 14-16) and sending it to Processor to perform the actual generation (lines 20-22). Next (line 11), you’re reading the HTML template from disk. In this case, you just say you want the template.html file to be converted to PDF. First (lines 6-8), you’re preparing the PDF Generation schema that describes the HTML-to-PDF conversion.
