Promisification

The Electron team recently underwent an initiative to convert callback-based APIs to Promise-based ones. See converted functions below:

• app.getFileIcon(path[, options], callback)
• contents.capturePage([rect, ]callback)
• contents.executeJavaScript(code[, userGesture, callback])
• contents.printToPDF(options, callback)
• contents.savePage(fullPath, saveType, callback)
• contentTracing.getCategories(callback)
• contentTracing.startRecording(options, callback)
• contentTracing.stopRecording(resultFilePath, callback)
• contentTracing.getTraceBufferUsage(callback)
• cookies.flushStore(callback)
• cookies.get(filter, callback)
• cookies.remove(url, name, callback)
• cookies.set(details, callback)
• debugger.sendCommand(method[, commandParams, callback])
• desktopCapturer.getSources(options, callback)
• dialog.showOpenDialog([browserWindow, ]options[, callback])
• dialog.showSaveDialog([browserWindow, ]options[, callback])
• inAppPurchase.purchaseProduct(productID, quantity, callback)
• inAppPurchase.getProducts(productIDs, callback)
• dialog.showMessageBox([browserWindow, ]options[, callback])
• dialog.showCertificateTrustDialog([browserWindow, ]options, callback)
• netLog.stopLogging([callback])
• protocol.isProtocolHandled(scheme, callback)
• ses.clearHostResolverCache([callback])
• ses.clearStorageData([options, callback])
• ses.setProxy(config, callback)
• ses.resolveProxy(url, callback)
• ses.getCacheSize(callback)
• ses.clearAuthCache(options[, callback])
• ses.clearCache(callback)
• ses.getBlobData(identifier, callback)
• shell.openExternal(url[, options, callback])
• webFrame.executeJavaScript(code[, userGesture, callback])
• webFrame.executeJavaScriptInIsolatedWorld(worldId, scripts[, userGesture, callback])
• webviewTag.capturePage([rect, ]callback)
• webviewTag.executeJavaScript(code[, userGesture, callback])
• webviewTag.printToPDF(options, callback)
• win.capturePage([rect, ]callback)
