You need to use [**Electron Packager**](https://github.com/electron-userland/electron-packager).

**Install** it using:

    # for use in npm scripts
    npm install electron-packager --save-dev
    
    # for use from cli
    npm install electron-packager -g

And package or deploy using:

    electron-packager &lt;sourcedir&gt; &lt;appname&gt; --platform=win32 --arch=x86_64

If you would like to keep it with the Electron Installation, see [**Application Distribution**](https://github.com/electron/electron/blob/master/docs/tutorial/application-distribution.md#packaging-your-app-into-a-file).

**Update :**

Above command might throw an error
&gt; Unsupported arch=x86_64 (string); must be a string matching: ia32, x64, armv7l, arm64, mips64el

Suggested to use one of the options from ia32, x64, armv7l, arm64, mips64el

    electron-packager &lt;sourcedir&gt; &lt;appname&gt; --platform=win32 --arch=x64

I try to shorten my imports in typescript

from `import {Hello} from &quot;./components/Hello&quot;;`

to `import {Hello} from &quot;Hello&quot;;`

For that I found out you can use `resolve.alias` in webpack thus I configured that part as following

    resolve: {
        root: path.resolve(__dirname),
        alias: {
            Hello: &quot;src/components/Hello&quot;
        },
        extensions: [&quot;&quot;, &quot;.ts&quot;, &quot;.tsx&quot;, &quot;.js&quot;]
    },

Webpack builds, and the output bundle.js works. However typescript&#39;s intellisense complain it `cannot find the module`


So my question is whether or not webpack&#39;s resolve.alias works with typescript?

I found following [issue][1] but there&#39;s no answer to it.

I&#39;ve been learning how to create applications in [Electron][1] and I need help compiling a simple project to a Windows executable. The program is a clone from this Github repo: [https://github.com/electron/electron-quick-start][2]. On the repo readme it shows how to run the program:

    # Clone this repository
    git clone https://github.com/electron/electron-quick-start
    # Go into the repository
    cd electron-quick-start
    # Install dependencies
    npm install
    # Run the app
    npm start

This works fine, but I can&#39;t figure out how to simply compile it. I&#39;ve looked all over google, you would think that something as simple as deploying an application would be well known information.

I have been using the YouTube IFrame Player API without problem for months and started to see this exception recently when the player loads:
`Uncaught ReferenceError: ytcfg is not defined`
Inspecting the iframe, I see a successful call to `yt.setConfig`, but `ytcfg.set` fails later. Was the API changed recently? Any player parameter could cause this problem?

I have an object called `this.props` which contains

    {
     actions: Object,
     dirty: false,
     form: &quot;Statement&quot;,
     autofill: function(),
     **statement: Object**
    }

`statement` contains

    {
     firstName: &quot;John&quot;
     lastName: &quot;Peter&quot;
     isConfirmed: true
    }

I would like to extract `statement` object and the `isConfirmed` property in the same line using es6 destructuring

I&#39;ve tried 

    const { statement: isConfirmed, isAdmin } = this.props

which I get an error when I do `let a = isConfirmed, b = statement`

ES6 deep nested object destructuring

I have some code that is iterating over a list that was queried out of a database and making an HTTP request for each element in that list.  That list can sometimes be a reasonably large number (in the thousands), and I would like to make sure I am not hitting a web server with thousands of concurrent HTTP requests.

An abbreviated version of this code currently looks something like this...

    function getCounts() {
      return users.map(user =&gt; {
        return new Promise(resolve =&gt; {
          remoteServer.getCount(user) // makes an HTTP request
          .then(() =&gt; {
            /* snip */
            resolve();
          });
        });
      });
    }
    
    Promise.all(getCounts()).then(() =&gt; { /* snip */});

This code is running on Node 4.3.2.  To reiterate, can `Promise.all` be managed so that only a certain number of Promises are in progress at any given time?

What is the best way to limit concurrency when using ES6&#39;s Promise.all()?

I&#39;m super new to React and I&#39;m trying to get it set up for Meteor and piecing stuff together from other sources too. One of these other sources set up console logging for the app, but I&#39;m going the ES6/JSX way so just using their code wouldn&#39;t work for me (or it doesn&#39;t seem like it does).

Some code I found for logging is

    import Logger from &#39;simple-console-logger&#39;;
    Logger.configure({level: &#39;debug&#39;});

but I&#39;m seeing this error
[![cannot find module &#39;./dumy&#39;][1]][1]

I also tried using `react-logger` and `react-console-logger` to no avail. Here&#39;s my code for the latter, which I believe should work.

    import {Logger, ConsoleLogger} from &#39;react-console-logger&#39;;
    const myLogger = new Logger();
    export default class App extends Component {
        render() {
            myLogger.info(&#39;something witty&#39;);
        }
    }

However, `myLogger.info(&#39;...&#39;)` is making a call to `node_modules/react-console-logger/lib/Logger.js` which has it defined as

[![picture of code since copy-paste doesn&#39;t work][2]][2]

And `this.logger` is undefined, although I see it be defined above?

Does anyone know what I&#39;m doing wrong? It looks to me like the library has it wrong, but maybe it has something to do with me using JSX files instead of js?

I have a React + Webpack/Babel + Node/Express application and I want to deploy it on AWS.

I would like to deploy an application cluster by managing my deployment via k8s Deployment object. The documentation has me extremely confused. My basic layout has the following components that scale independently:

 1. API server
 2. UI server
 3. Redis cache
 4. Timer/Scheduled task server

Technically, all 4 above belong in separate pods that are scaled independently. 

My questions are:

 1. Do I need to create `pod.yml` files and then somehow reference them in `deployment.yml` file or can a deployment file also embed pod definitions?
 2. K8s documentation seems to imply that the `spec` portion of `Deployment` is equivalent to defining *one* pod. Is that correct? What if I want to declaratively describe multi-pod deployments? Do I do need multiple deployment.yml files?

I&#39;ve heard both used to describe the idea of deploying an update on new machines while keeping old machines active, ready to rollback if an issue occurs. I&#39;ve also heard it used to describe sharing load between updated services and old service, again for the purpose of a rollbacks —sometimes terminating inactive older patches and sometimes not.

My understanding also is that it is strictly for cloud services. 

Can someone help to demystify these terms?

We have an Angular 6 application. It’s served on Nginx. And SSL is on.

When we deploy new codes, most of new features work fine but not for some changes. For example, if the front-end developers update the service connection and deploy it, users have to open incognito window or clear cache to see&#160;the new feature.

What&#160;type of changes are not updated automatically? Why are they different from others?

I have a script I run to deploy 2 web services and a front-end application. The script calls a method that checks to see if the 2 back-end services are up and running. If so, deem the deploy successful, otherwise revert.

The 2 services sometimes take longer than the front-end to start up. Currently I put in a sleep call to delay the web service check. This allows them time to start up.

I want to remove this sleep and add in a retry mechanism so that if a service is down, just retry the check repeatedly until I get a response.

Tp check if the device is up, I use curl. I&#39;ve read that curl has a retry mechanism but I&#39;ve never used it.

Have any of you solved this problem before? I want to understand the things I must consider when solving it, e.g. do I retry until i get a HTTP 200 from my service?

Anyone any suggestions how I&#39;d test this? I&#39;d need to find a service that was down.

EDIT: I see that -retry only reacts to transient errors &#39;Transient error means either: a timeout, an FTP 4xx response code or an HTTP 5xx response code&#39;. My service can return a 404 therefore curl&#39;s retry is not my solution.

I am currently working on a standard Windows desktop application (standard meaning no fancy stuff: just buttons, text, sliders, etc.), and have decided to write a GUI framework on my own, after looking into some GUI frameworks and being repelled by all of them. Since it’s a hobby project, I am also willing to experiment, and decided to make the GUI immediate-mode, not retained-mode, as I really like the way it simplifies the code. Here is the question, though:

**What are the performance implications of using an immediate-mode GUI compared to a retained-mode GUI, when using it for a typical desktop application?**

I always hear that an IMGUI performs worse, since it has to redraw every frame (or, if it somehow caches, it still has to do the logic every frame). But of how much more are we talking here? Am I burning twice the CPU time? More? If I hypothetically ran 20&#160;IMGUI programs, would it max out the CPU (presuming I already optimized it)? I just want to know the ballpark and whether the tradeoffs are still viable in a non-game environment, where there is no need to redraw every frame.

There is also one more implication concerning latency that I don’t understand. In the [chapter discussing IMGUI][johno-chapter] in a [work-in-progress book][johno-book] by [Johannes Norneby][johno], it is explained as follows:

&gt; ### Frame shearing
&gt; 
&gt; One aspect of IMGUI to be aware of in the context of real-time
&gt; applications (constantly rendering new frames many times per second)
&gt; is that user interactions will always be in response to something that
&gt; was drawn on a previous frame. This is because the user interface must
&gt; be drawn at least once for the user to be aware that there are widgets
&gt; there to be interacted with. Most of the time this doesn’t cause any
&gt; problems if the frame rate is high enough, but it is something to be
&gt; aware of.

How is this any different in a retained-mode GUI? Does it mean that I have one more frame of input lag over a retained-mode GUI?

Evening,&lt;br&gt;
I&#39;m looking into using [electron][1] to package an existing angular2 build. I thought I had a dry run working but the actual packaging seems to be failing (see final step below) and I want to understand why. Here&#39;s what I&#39;m doing...

**Create Project**&lt;br&gt;
Use [angular-cli][2] to start a new project `ng new electron-ng2-cli --style=scss`

Install electron and [electron-builder][3]

**Edit package.json**&lt;br&gt;Make the following additions...&lt;br&gt;
 `&quot;main&quot;: &quot;main.js&quot;`

    &quot;build&quot;:
    {
      &quot;appId&quot;: &quot;com.electrontest.testapp&quot;,
      &quot;mac&quot;: {
        &quot;category&quot;: &quot;your.app.category.type&quot;
      }
    }
and add the following to the `scripts`...

    &quot;pack&quot;: &quot;build --dir&quot;,
    &quot;dist&quot;: &quot;build&quot;,
    &quot;electron&quot;: &quot;electron main.js&quot;,
    &quot;postinstall&quot;: &quot;install-app-deps&quot;

**Create main.js**&lt;br&gt;I just copied the code from the [electron quick start][4]. The only change I make is to the location of `index.html` which I set to `/dist/index.html`

**Amend base**&lt;br&gt;In `index.html` change `&lt;base=&quot;/&quot;&gt;` to `&lt;base=&quot;./&quot;&gt;` 

**Pack code**&lt;br&gt;Run `ng build`. This puts all the packaged code in `/dist`

**Test Run**&lt;br&gt;Run `npm run electron`. This works fine. An Electron app fires up and I see the angular stuff running within it.

**Create App For Distribution**&lt;br&gt;Run `npm run pack` to create a packaged app. The packaging seems to go ok - I get a warning about a missing icon and a warning that my code is unsigned but I&#39;m guessing they shouldn&#39;t be fatal?&lt;br&gt;
The problem is that when I now run the app by double clicking in `Finder` I get an error in the console saying: `Not allowed to load local resource: file:///Users/&lt;username&gt;/Documents/development/electron-ng2-cli/dist/mac/electron-ng2-cli.app/Contents/Resources/app.asar/dist/index.html`
&lt;hr&gt;
So, can anyone explain what is different between the packaged app that fails and the one that runs ok when I use `npm run electron`?

What can I do to fix this issue and get the app running correctly?

Thank you for making it to the end. This got longer than I wanted but I hope I explained myself ok. If you can help or give any pointers that would be great - many good vibes will be thought in your general direction :)

Cheers all

Electron - Not allowed to load local resource

I&#39;m working on a project with Typescript, React and Redux (all running in Electron), and I&#39;ve run into a problem when I&#39;m including one class based component in another and trying to pass parameters between them. Loosely speaking, I&#39;ve got the following structure for the container component:

    class ContainerComponent extends React.Component&lt;any,any&gt; {
      ..
      render() {
        const { propToPass } = this.props;
        ...
        &lt;ChildComponent propToPass={propToPass} /&gt;
        ...
      }
    }
    
    ....
    export default connect(mapStateToProps, mapDispatchToProps)(ContainerComponent);

And the child component:

    interface IChildComponentProps extends React.Props&lt;any&gt; {
      propToPass: any
    }

    class ChildComponent extends React.Component&lt;IChildComponentProps, any&gt; {
      ...
    }
    
    ....
    export default connect(mapStateToProps, mapDispatchToProps)(ChildComponent);

Obviously I&#39;m only including the basics and there is much more to both of these classes but I&#39;m still getting an error when I try and run what looks to me like valid code. The exact error that I&#39;m getting:

&gt;     TS2339: Property &#39;propToPass&#39; does not exist on type &#39;IntrinsicAttributes &amp; IntrinsicClassAttributes&lt;Component&lt;{}, ComponentState&gt;&gt; &amp; Readonly&lt;{ childr...&#39;.

When I first encountered the error I thought it was because I wasn&#39;t passing in an interface defining my props, but I created that (as you can see above) and it still doesn&#39;t work. I&#39;m wondering, is there something I&#39;m missing? 

When I exclude the ChildComponent prop from the code in the ContainerComponent, it renders just fine (aside from my ChildComponent not having a critical prop) but with it in the JSX Typescript refuses to compile it. I think it might have something to do with the connect wrapping based on [this article](http://www.mattgreer.org/articles/typescript-react-and-redux/), but the problems in that article occurred in the index.tsx file and were a problem with the provider, and I&#39;m getting my problems elsewhere.

I&#39;m creating an Electron app for my own purpose. My problem is when I&#39;m using node functions inside my HTML page it throws an error of:

&gt;&#39;require()&#39; is not defined.

Is there any way to use Node functionalities in all my HTML pages? If it is possible please give me an example of how to do this or provide a link. Here are the variables I&#39;m trying to use in my HTML page:

      var app = require(&#39;electron&#39;).remote; 
      var dialog = app.dialog;
      var fs = require(&#39;fs&#39;);

and these are the values I&#39;m using in all my HTML windows within Electron.

I have an Electron app that I&#39;m trying to install node modules for. When I run `npm install`, it creates the `node_modules` folder but all the modules go into a subfolder called `.staging`. Each module also has `-xxxxx` appended to it, where the x&#39;s are some random alphanumerics.

Other Electron apps I&#39;ve created have never done this. All the node modules sit in the root of `node_modules` and don&#39;t have `-xxxxx` appended.

Any idea why this is happening?
