&gt; Is it good to list as many as possible keywords for a package (hundred?) or this is a bad approach?

You should only use keywords that are relevant to your module and that you would expect people to use while searching for a module like yours.

So if you have a module that uses twitter and has a promise-based api then you may use keywords like &quot;twitter&quot; and &quot;promise&quot; but you shouldn&#39;t use irrelevant keywords just to spam the search results.

I cannot think of any legitimate reason to need that many keywords.

&gt; How to list keywords properly?

This is an example from my own module, [caught](https://www.npmjs.com/package/caught) - which, as you can see, uses 4 keywords:

    {
      &quot;name&quot;: &quot;caught&quot;,
      &quot;version&quot;: &quot;0.1.1&quot;,
      &quot;description&quot;: &quot;Avoids UnhandledPromiseRejectionWarning and PromiseRejectionHandledWarning&quot;,
      &quot;main&quot;: &quot;index.js&quot;,
      &quot;types&quot;: &quot;index.d.ts&quot;,
      &quot;scripts&quot;: {
        &quot;test&quot;: &quot;bash test.sh&quot;
      },

        &quot;url&quot;: &quot;git+https://github.com/rsp/node-caught.git&quot;
      },
      &quot;keywords&quot;: [
        &quot;promise&quot;,
        &quot;async&quot;,

Using Spark 1.6, I have a Spark `DataFrame column` (named let&#39;s say `col1`) with values A, B, C, DS, DNS, E, F, G and H and I want to create a new column (say `col2`) with the values from the `dict` here below, how do I map this? (so f.i. &#39;A&#39; needs to be mapped to &#39;S&#39; etc..)

    dict = {&#39;A&#39;: &#39;S&#39;, &#39;B&#39;: &#39;S&#39;, &#39;C&#39;: &#39;S&#39;, &#39;DS&#39;: &#39;S&#39;, &#39;DNS&#39;: &#39;S&#39;, &#39;E&#39;: &#39;NS&#39;, &#39;F&#39;: &#39;NS&#39;, &#39;G&#39;: &#39;NS&#39;, &#39;H&#39;: &#39;NS&#39;}

I am a newbie in Angular 2. I want to create isolated modules for every part of my app. For example I created the `AuthModule` with default component - `AuthComponent` which contain a `router-outlet` for his child components (SignIn or SignUp). So I want to realise the following scenario:

 1. When navigate to / - root off app - redirect to /auth
 2. After redirect to /auth - load AuthComponent with router outlet
 3. After AppComponent loaded - load default sign-in component via redirecting to /auth/sign-in

But when I going to localhost/ I get redirect to /auth what I want, but the next redirect to sign-in doesn&#39;t appear. 

My code:
`app.routing`

    const routes: Routes = [
      {
          path: &#39;&#39;, 
          redirectTo: &#39;/auth&#39;, 
          pathMatch: &#39;full&#39;
      }
    ];

    export const appRouting: ModuleWithProviders = RouterModule.forRoot(routes);

`auth.routing`

    const routes: Routes = [
      {
        path: &#39;auth&#39;,
        component: AuthComponent,
        children: [
          {
             path: &#39;&#39;, 
             redirectTo: &#39;sign-in&#39;, 
             pathMatch: &#39;full&#39;
          },
          {
             path: &#39;sign-in&#39;, 
             component: SignInComponent
          }
        ]
      },
    
    ];
    
    export const authRouting: ModuleWithProviders = RouterModule.forChild(routes);

`auth.component.html`

    &lt;div class=&quot;container&quot;&gt;
        &lt;h1&gt;Auth component&lt;/h1&gt;
        &lt;router-outlet&gt;&lt;/router-outlet&gt;
    &lt;/div&gt;

I&#39;m using Laravel Mix, that is based on WebPack.

I had it working, and now, it fails with:


    Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
    - configuration.output.path: The provided value &quot;public&quot; is not an absolute path!

If I delete my webpack.mix.js content, it still fails the same way.

Can you help me debug this error, I have no clue how to go forward.

I have already deleted the node_modules folder, and ran `npm install`, it is still failing. 

Any idea how should I solve this?

I am using Node.js, and I want to obtain the parent directory name for a 
file. I have the file `&quot;../test1/folder1/FolderIWant/test.txt&quot;`.

I want to get `&quot;FolderIWant&quot;`.

I have tried:

    var path = require(&#39;path&#39;);
    var parentDir = path.dirname(filename);

But it returns `../test1/folder1/FolderIWant`.

After uploading a file in Firebase Storage with Functions for Firebase, I&#39;d like to get the download url of the file.

I have this :

    ...
    
    return bucket
        .upload(fromFilePath, {destination: toFilePath})
        .then((err, file) =&gt; {
            
            // Get the download url of file
    
        });


The object file has a lot of parameters. Even one named `mediaLink`. However, if I try to access this link, I get this error :

&gt; Anonymous users does not have storage.objects.get access to object ...

Can somebody tell me how to get the public download Url?

Thank you

I am sending requests from the client to my Express.js server using Axios. 

I set a cookie on the client and I want to read that cookie from all Axios requests without adding them manually to request by hand. 

This is my clientside request example:

    axios.get(`some api url`).then(response =&gt; ...

I tried to access headers or cookies by using these properties in my Express.js server:

    req.headers
    req.cookies

Neither of them contained any cookies. I am using cookie parser middleware:

    app.use(cookieParser())

How do I make Axios send cookies in requests automatically? 

Edit:

I set cookie on the client like this:

    import cookieClient from &#39;react-cookie&#39;
    
    ...
    let cookie = cookieClient.load(&#39;cookie-name&#39;)
    if(cookie === undefined){
          axios.get(&#39;path/to/my/cookie/api&#39;).then(response =&gt; {
            if(response.status == 200){
              cookieClient.save(&#39;cookie-name&#39;, response.data, {path:&#39;/&#39;})
            }
          })
        }
    ...
While it&#39;s also using Axios, it is not relevant to the question. I simply want to embed cookies into all my requests once a cookie is set. 








Make Axios send cookies in its requests automatically

When running my Express application in production, I want to shut down the server gracefully when its process is killed (i.e. a `SIGTERM` or `SIGINT` is sent).

Here is a simplified version of my code:

    const express = require(&#39;express&#39;);

    const app = express();

    app.get(&#39;/&#39;, (req, res) =&gt; res.json({ ping: true }));

    const server = app.listen(3000, () =&gt; console.log(&#39;Running…&#39;));

    setInterval(() =&gt; server.getConnections(
        (err, connections) =&gt; console.log(`${connections} connections currently open`)
    ), 1000);

    process.on(&#39;SIGTERM&#39;, shutDown);
    process.on(&#39;SIGINT&#39;, shutDown);

    function shutDown() {
        console.log(&#39;Received kill signal, shutting down gracefully&#39;);
        server.close(() =&gt; {
            console.log(&#39;Closed out remaining connections&#39;);
            process.exit(0);
        });

        setTimeout(() =&gt; {
            console.error(&#39;Could not close connections in time, forcefully shutting down&#39;);
            process.exit(1);
        }, 10000);
    }

When I run it and call the URL http://localhost:3000/ in a browser, the log statement in the setInterval function will keep printing “1 connection currently open” until I actually close the browser window. Even closing the tab will keep the connection open, apparently.

So when I kill my server by hitting Ctrl+C, it will run into the timeout and print “Could not close connections” after 10 seconds, all the while continuing to print “1 connection open”.

Only if I close the browser window before killing the process I get the “closed out remaining connections” message.

**What am I missing here? What is the proper way to shut down an Express server gracefully?**

When multiple git branches modify the dependencies in a project that uses [Yarn][1], it is likely to introduce a conflict in the yarn.lock file. It is not a good idea to delete and regenerate the yarn.lock file because this will probably cause several packages to be unintentionally upgraded. What is the best way to quickly resolve conflicts in this file?
