When you get the No overload matches this call. error, means you are defining parameters that do not exist on that type.

In your case, you have the err parameter on listen callback which should not be there (see http://expressjs.com/en/api.html under app.listen)

To fix the ts error, just remove the err and related code below.

Regarding your imports, I would suggest to keep them with the newer sintax instead of the old require (that should now work just fine).

Last but not least, try to always avoid setting your types as any, as that is like having a fire alarm without batteries. The types you are looking for are express built-in and you can define them as such:

You should add a check for what the request returns. If it returns an empty list, it cannot be used as a random.choice() argument, since it requires a list with one or more item.

This part of this error

Declare ListItem as an struct instead of a class, this way the view will be notified when isFavorite changes. And just a little suggestion; you can use toggle to change the value of a boolean: self.list.items[index].isFavorite.toggle()

This sounds like a job for regular expressions to me.

I would do something like this:

This is a sample of one line of the OP's XML file
109555912.69

The OP wants to use the IMPORTXML function to report the ID and Name as well as the Job Cost from the XML data. Presently, the OP's formula is:
=importxml("link","//job-base-cost")

There are two options:
1 - One long column
=importxml("link","//@id | //@name | //job-base-cost")

Note //@id and //@name in the xpath query: // indicate nodes in the document (at any level, not just the root level) and @ indicate attributes. The pipe | operator indicates AND. So the plain english query is to display the id, name and job-base-cost.

2 - Three columns (table format)
={IMPORTXML("link","//@name"),IMPORTXML("link","//job-base-cost"),IMPORTXML("link","//@id")}

This creates a series that will display the fields in each of three columns.

Note: there is an arrayformula that uses a single importXML function described in How do I return multiple columns of data using ImportXML in Google Spreadsheets?. Readers may want to look at whether that option can be implemented.

My thanks to @Tanaike for his comment which spurred me to look at how xpath works.

Usually you should at least try something before posting a question on Stack Overflow, but since it's one of your first posts, I don't want to be rude so here's a full answer.

Using the standard xml library you can do this very easily.

Here's an example for exactly the behavior you described:

Use :

You can do this by using melt on df1 and merge.
