Javascript Regex to match 2 URLs

I have this kind of URLs that i wanted to match it using RegEx.

  1. "http://example.com/sample/company/123/invoices/download/123a_1a23
  2. "http://example.com/sample/company/123/invoices/view/123a_12a3"

The first 123 is always numeric, while the 2nd 123a_12a3 is alphanumeric and can have an underscore.

I want to create a regex that will check if it will match those 2 URLs above.

I created this code:

let result = new RegExp('\\binvoices/download\\b').test(url);

That works but i think there's a better way to do it to match those 2 URLs and maybe check if those 2 parameters exists, because right now that only matches 1.

I'm new to Regex, so any help is greatly appreciated!

Thanks.

Something like this should match either of those URLs

const rx = /\/sample\/company\/\d+\/invoices\/(download|view)\/\w+$/

const urls = [
  "http://example.com/sample/company/123/invoices/download/123a_1a23",
  "http://example.com/sample/company/123/invoices/view/123a_12a3",
  "http://example.com/sample/other/123/invoices/view/123a_12a3",
  "http://example.com/sample/company/123/invoices/upload/123a_12a3",
]

urls.forEach(url => console.log(url.slice(18), rx.test(url)))

Breaking it down...

\/sample\/company\/ - literal "/sample/company/"
\d+                 - one or more numbers
\/invoices\/        - literal "/invoices/"
(download|view)     - "download" or "view"
\/                  - a literal "/"
\w+                 - one or more "word" characters, ie alpha-numeric or underscore
$                   - the end of the string

Try:

var result = new RegExp('invoices\/(download|view)\/', "i").test(url);

the ( and ) parenthesis with a pipe allow you to check two things.
