Crete ZIP file in memory

If GZip will do, you can use the built-in zlib module and not even have to load an external module.

const zlib = require('zlib');
const gzip = zlib.createGzip();

// If you have an inputStream and an outputStream:

inputStream.pipe(gzip).pipe(outputStream);

For Zip and not GZip, you can check out archiver or zip-stream.

All the unzipping for all the files

const fs = require('fs');
	const zlib = require('zlib');
	const directoryFiles = fs.readdirSync('./data');
	directoryFiles.forEach(filename => {
	const fileContents = fs.createReadStream(`./data/${filename}`);
	const writeStream = fs.createWriteStream(`./data/${filename.slice(0, -3)}`);
	const unzip = zlib.createGunzip();
	fileContents.pipe(unzip).pipe(writeStream);
	});

Node Upload S3 folder

Bucket is name of your bucket and key is name of subfolder. So, if your bucket name is “test-bucket” and you want to save file in “test-bucket/folder/subfolder/file.csv”, then value of Key should be “folder/subfolder/file.csv”.

Can't bind to 'routerLink' since it isn't a known property

Source: https://stackoverflow.com/questions/42035387/cant-bind-to-routerlink-since-it-isnt-a-known-property

You need to add RouterModule to imports of every @NgModule() where components use any component or directive from (in this case routerLink and <router-outlet>.

declarations: [] is to make components, directives, pipes, known inside the current module.

exports: [] is to make components, directives, pipes, available to importing modules. What is added to declarations only is private to the module. exports makes them public.

Select element based on multiple classes

Source: https://stackoverflow.com/questions/2554839/select-element-based-on-multiple-classes

You mean two classes? "Chain" the selectors (no spaces between them):

.class1.class2 {
    /* style here */
}

This selects all elements with class1 that also have class2.

In your case:

li.left.ui-class-selector {

}

bootstrap dropdown bubble align right (not push-right)

Source: https://stackoverflow.com/questions/18892351/bootstrap-dropdown-bubble-align-right-not-push-right

Bootstrap 3.1+

Adding the class .dropdown-menu-right to the same div containing the class dropdown-menu:

<div class="dropdown-menu dropdown-menu-right">
    STUFF
</div>

http://getbootstrap.com/components/#dropdowns-alignment

Bootstrap 2.3 & 3.0

Add the class .pull-right to the same div containing the class dropdown-menu

<div class="dropdown-menu pull-right">
    STUFF
</div>

This seems to work for me using bootstrap 3.0

Download a file from NodeJS Server using Express

Source:

Update

Express has a helper for this to make life easier.

app.get('/download', function(req, res){
  const file = `${__dirname}/upload-folder/dramaticpenguin.MOV`;
  res.download(file); // Set disposition and send it.
});

Old Answer

As far as your browser is concerned, the file's name is just 'download', so you need to give it more info by using another HTTP header.

res.setHeader('Content-disposition', 'attachment; filename=dramaticpenguin.MOV');

You may also want to send a mime-type such as this:

res.setHeader('Content-type', 'video/quicktime');

If you want something more in-depth, here ya go.

var path = require('path');
var mime = require('mime');
var fs = require('fs');

app.get('/download', function(req, res){

  var file = __dirname + '/upload-folder/dramaticpenguin.MOV';

  var filename = path.basename(file);
  var mimetype = mime.lookup(file);

  res.setHeader('Content-disposition', 'attachment; filename=' + filename);
  res.setHeader('Content-type', mimetype);

  var filestream = fs.createReadStream(file);
  filestream.pipe(res);
});

You can set the header value to whatever you like. In this case, I am using a mime-type library - node-mime, to check what the mime-type of the file is.

Another important thing to note here is that I have changed your code to use a readStream. This is a much better way to do things because using any method with 'Sync' in the name is frowned upon because node is meant to be asynchronous.
