|
+## When will Electron upgrade to latest Chrome?
|
|
|
+
|
|
|
+The Chrome version of Electron is usually bumped within one or two weeks after
|
|
|
+a new stable Chrome version gets released.
|
|
|
+
|
|
|
+Also we only use stable channel of Chrome, if an important fix is in beta or dev
|
|
|
+channel, we will back-port it.
|
|
|
+
|
|
|
+## When will Electron upgrade to latest Node.js?
|
|
|
+
|
|
|
+When a new version of Node.js gets released, we usually wait for about a month
|
|
|
+before upgrading the one in Electron. So we can avoid getting affected by bugs
|
|
|
+introduced in new Node.js versions, which happens very often.
|
|
|
+
|
|
|
+New features of Node.js are usually brought by V8 upgrades, since Electron is
|
|
|
+using the V8 shipped by Chrome browser, the shiny new JavaScript feature of a
|
|
|
+new Node.js version is usually already in Electron.
|
|
|

|
|
|
+## My app's window/tray disappeared after a few minutes.
|
|
|
+
|
|
|
+This happens when the variable which is used to store the window/tray gets
|
|
|
+garbage collected.
|
|
|
+
|
|
|
+It is recommended to have a reading of following articles you encountered this
|
|
|
+problem:
|
|
|
+
|
|
|
+* [Memory Management][memory-management]
|
|
|
+* [Variable Scope][variable-scope]
|
|
|
+
|
|
|
+If you want a quick fix, you can make the variables global by changing your
|
|
|
+code from this:
|
|
|
+
|
|
|
+```javascript
|
|
|
+app.on('ready', function() {
|
|
|
+ var tray = new Tray('/path/to/icon.png');
|
|
|
+})
|
|
|
+```
|
|
|
+
|
|
|
+to this:
|
|
|
+
|
|
|
+```javascript
|
|
|
+var tray = null;
|
|
|
+app.on('ready', function() {
|
|
|
+ tray = new Tray('/path/to/icon.png');
|
|
|
+})
|
|
|
+```
|
|
|
+
|
|
|
+## I can not use jQuery/RequireJS/Meteor/AngularJS in Electron.
|
|
|
+
|
|
|
+Due to the Node.js integration of Electron, there are some extra symbols
|
|
|
+inserted into DOM, like `module`, `exports`, `require`. This causes troubles for
|
|
|
+some libraries since they want to insert the symbols with same names.
|
|
|
+
|
|
|
+To solve this, you can turn off node integration in Electron:
|
|
|
+
|
|
|
+```javascript
|
|
|
+// In the main process.
|
|
|
+var mainWindow = new BrowserWindow({
|
|
|
+ webPreferences: {
|
|
|
+ nodeIntegration: false
|
|
|
+ }
|
|
|
+});
|
|
|
+```
|
|
|
+
|
|
|
+But if you want to keep the abilities of using Node.js and Electron APIs, you
|
|
|
+have to rename the symbols in the page before including other libraries:
|
|
|
+
|
|
|
+```html
|
|
|
+<head>
|
|
|
+<script>
|
|
|
+window.nodeRequire = require;
|
|
|
+delete window.require;
|
|
|
+delete window.exports;
|
|
|
+delete window.module;
|
|
|
+</script>
|
|
|
+<script type="text/javascript" src="jquery.js"></script>
|
|
|
+</head>
|
|
|
+```
