The difference is documented [here](http://pm2.keymetrics.io/docs/usage/cluster-mode/#reload):

&gt; As opposed to `restart`, which kills and restarts the process, `reload` achieves a 0-second-downtime reload.

The latter means (found [here](https://pm2.io/docs/runtime/guide/load-balancing/#0-seconds-downtime-reload)):

&gt; With reload, `pm2` restarts all processes one by one, always keeping at least one process running.

It also states that:

&gt; If the reload system hasn’t managed to reload your application, a timeout will fallback to a classic restart.

I&#39;m getting the following **runtime error**:

     checkParameterIsNotNull, parameter oneClickTokens
        at com.info.app.fragments.Fragment_Payment_Profile$fetchMerchantHashes$1.onPostExecute(Fragment_Payment_Profile.kt:0)
        at com.info.app.fragments.Fragment_Payment_Profile$fetchMerchantHashes$1.onPostExecute(Fragment_Payment_Profile.kt:1543)


Here&#39;s **my code**:

     private fun fetchMerchantHashes(intent: Intent) {
        // now make the api call.
        val postParams = &quot;merchant_key=$key&amp;user_credentials=$var1&quot;
        val baseActivityIntent = intent
        object : AsyncTask&lt;Void, Void, HashMap&lt;String, String&gt;&gt;() {
    
            override fun doInBackground(vararg params: Void): HashMap&lt;String, String&gt;? {
                    ...
            }
    
            override fun onPostExecute(oneClickTokens: HashMap&lt;String, String&gt;) {
                super.onPostExecute(oneClickTokens)
                ...
    
            }
        }.execute()
    }


It seems that the function call seems to be invalid. However, I don&#39;t know how to fix this problem. Is there anything Kotlin specific I&#39;ve missed?

I tried to create account on [aws.amazon.com][1]. But it needs credit card information to complete the login process. 

As I do not intend to use AWS for any commercial purpose but for academic/self-learning purpose, is there way to create a trial account ( probably a limited version say limited functionalities or limited time period )

I have a nodejs app running on server.

When should I use **pm2 restart**,and when should **pm2 reload** be used?

Referred to the [pm2 documention][1] here,but couldn&#39;t figure out the difference in use case of the two.

What is the difference between pm2 restart and pm2 reload

I have a nodejs app running on server.
When should I use pm2 restart,and when should pm2 reload be used?
Referred to the <a href="https://github.com/Unitech/pm2#reloading-without-downtime" target="_blank" rel="noopener noreferrer">pm2 documention</a> here,but couldn't figure out the difference in use case of the two.

Either I don&#39;t understand `dependencies` vs. `devDependencies` in node 100% yet or eslint is just wrong here (not capable of analyzing this correctly):

       3:1   error  &#39;chai&#39; should be listed in the project&#39;s dependencies, not devDependencies              import/no-extraneous-dependencies
       4:1   error  &#39;chai-enzyme&#39; should be listed in the project&#39;s dependencies, not devDependencies       import/no-extraneous-dependencies
       5:1   error  &#39;enzyme&#39; should be listed in the project&#39;s dependencies, not devDependencies            import/no-extraneous-dependencies
       7:1   error  &#39;sinon&#39; should be listed in the project&#39;s dependencies, not devDependencies             import/no-extraneous-dependencies
       9:1   error  &#39;redux-mock-store&#39; should be listed in the project&#39;s dependencies, not devDependencies  import/no-extraneous-dependencies



These are test dependencies, so why is it saying that they should be listed in `dependencies`?  

Additional note: We&#39;re using Travis as our CI so I don&#39;t know if it makes a difference for that at all either.

eslint should be listed in the project&#39;s dependencies, not devDependencies

## Failed at Connecting `Node.js Server` to `MySQL-Database`
________

&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; 
I had **MariaDB&quot;** installed on a **&quot;Node.js Server&quot;**, but decided that I wanted to use a SQL Database instead. I uninstalled, and completely removed **&quot;MariaDB&quot;**, after which, I proceeded to install the _&quot;Community Ed.&quot; **&quot;MySQL Database&quot;**. After going through the entire *_&#39;MySQL Setup Process&#39;_**, I made several attempts to connect to the database via a JavaScript document that implemented the de facto code snippet for a JS DB Connection — _my DB-connection document is posted as a code snippet bellow_ — shown in the code snippet bellow_. Disappointingly, the JS/SQL connection failed at each attempt.

&lt;br&gt;
&lt;br&gt;


#### Here is the Failed Connection Error Message that I received:
--------

```txt

&quot;ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication
protocol requested by server. Consider upgrading MariaDB client.&quot;

```

&lt;br&gt;&lt;br&gt;


#### JS/SQL Connection Snippet that I am using:
--------


```JS

    var mysql = require(&#39;mysql&#39;);
    
    var connection = mysql.createConnection({
        host     : &#39;localhost&#39;,
        user     : &#39;root&#39;,

When I run gulp I get the following error:
    
    [12:54:14] { [GulpUglifyError: unable to minify JavaScript]
    cause:
    { [SyntaxError: Unexpected token: operator (&gt;)]
     message: &#39;Unexpected token: operator (&gt;)&#39;,
     filename: &#39;bundle.js&#39;,
     line: 3284,
     col: 46,
     pos: 126739 },
    plugin: &#39;gulp-uglify&#39;,
    fileName: &#39;C:\\servers\\vagrant\\workspace\\awesome\\web\\tool\\bundle.js&#39;,
    showStack: false }

The offending line contains an arrow function:
    
    let zeroCount = numberArray.filter(v =&gt; v === 0).length

I know I can replace it with the following to remedy the minification error by abandoning ES6 syntax:
        
    let zeroCount = numberArray.filter(function(v) {return v === 0;}).length

How can I minify code containing ES6 features via gulp?

Today, while working through some basic AngularJS introduction, I ran into a problem.

I opened PowerShell to get going on the project. NPM worked. 

I was able to install Angular using:

    npm install -g @angular/cli

Anytime I tried to run *ng*, I would get: 

&gt; the term &#39;ng&#39; is not recognized as the name of a cmdlet

I have installed webpack in this way:

    npm install -g webpack

Now want to uninstall it:

    npm uninstall -g webpack

Check it again, it didn&#39;t been uninstalled:

    webpack -v
    3.1.0

Why?

---

And, I use this way can&#39;t find `webpack`:

    npm list -g | grep webpack

---

This also didn&#39;t work:

    npm uninstall -g webpack --save

---

After run this under a directory which included `package.json`:

    npm uninstall webpack
    npm WARN babel-loader@6.4.1 requires a peer of webpack@1 || 2 || ^2.1.0-beta || ^2.2.0-rc but none was installed.
    npm WARN uglifyjs-webpack-plugin@0.3.1 requires a peer of uglify-js@^2.8.0 but none was installed.

How to uninstall global package with npm?

I have an electron app which uses pm2 to start some apps using the pm2 module.Everything is fine.However I am trying to implement the following feature:Renaming an app you have started.I know that using the cli I can do the following:

`pm2 restart app --name&quot;New name&quot;`;

So I found the `pm2.restart` function which takes an Object and a callback as a parameter.So I tried this:



    var options = {app:&quot;Blogsport App&quot;,name:&quot;New name&quot;};
    var callback = function(err){
       if(err) {console.log(&#39;Failed&#39;)}
       else {console.log(&#39;App renamed&#39;)}
    };
    
    pm2.restart(options,callback);

This will always log &quot;App renamed&quot;.However If I do `pm2 list` I see that the app has not be renamed.Is there anything I can do to rename an app without deleting it and start it again with a different name?

We have been using pm2 quite successfully for running apps on our servers. We are currently moving to docker and we saw http://pm2.keymetrics.io/docs/usage/docker-pm2-nodejs/

But what is the point of actually using both together? Does not docker provide everything pm2 does?
