sketch-module-web-view

A Sketch module for creating a complex UI with a webview.

Installation

To use this module in your Sketch plugin you need a bundler utility like skpm and add it as a dependency:

npm i -S sketch-module-web-view

Usage

import WebUI from 'sketch-module-web-view'

const options = {
  identifier: 'unique.id', // to reuse the UI
  x: 0,
  y: 0,
  width: 240,
  height: 180,
  background: NSColor.whiteColor(),
  blurredBackground: false,
  onlyShowCloseButton: false,
  title: 'My ui',
  hideTitleBar: false,
  shouldKeepAround: true,
  resizable: false,
  frameLoadDelegate: { // https://developer.apple.com/reference/webkit/webframeloaddelegate?language=objc
    'webView:didFinishLoadForFrame:': function (webView, webFrame) {
      context.document.showMessage('UI loaded!')
      WebUI.clean()
    }
  },
  uiDelegate: {}, // https://developer.apple.com/reference/webkit/webuidelegate?language=objc
  onPanelClose: function () {
    // Stuff
    // return `false` to prevent closing the panel
  }
}

const webUI = new WebUI(context, require('./my-screen.html'), options)

Communicating with the webview

Executing JS on the webview from the plugin

const res = webUI.eval('someJSFunction()')

Executing JS in the plugin from the webview

On the plugin:

options.handlers = {
  nativeLog: function (s) {
    context.document.showMessage(s)
  }
}

On the webview:

import pluginCall from 'sketch-module-web-view/client'

pluginCall('nativeLog', 'Called from the webview')

⚠️ When using options.handlers, the webView:didChangeLocationWithinPageForFrame: method of the frameLoadDelegate will be overwritten.
