urlregex | URL validation for Node and the browser | Runtime Evironment library

I have a text and a script

I have a textarea how can i be able to extract url's from that textarea value. the url's can be a random multiple urls. I was trying with the approach below but I am facing the problems below with this approach -

1. regex is not working if i add multiple new lines(shift+enter).Eg: two or three more new lines.
2. if I add url like 1. https://www.google.com, 2. https://www.facebook.com then it is not extracting the url.
3. if I add the url after writting some text Eg: (new text here https://www.google.com)
4. if I add url after hyphen Eg: (new text here - https://www.google.com)

Question - How can I extract url's from the textarea value in a format like this

["https://www.google.com","https://www.facebook.com","http://www.test.co","http://www.news.co.in",]

I am on the learning curve for gcloud app deploy. I have been struggling with running the .net HelloWorld example code from this location:

I developed an application for my personal use that parses mail messages from Youtube sent to my e-mail account, then it extracts the video url from each message.

I use this application once in a month or two, and the next regular expression was working perfectly for 1~2 years and the last time I used the application:

C# Syntax:

I'm trying to replay any occurrence of a link in a text as a link, but I only get it to show the example.com as text in the message. (Just to be clear, it shows other message content if there is other content in the message than the link, but the link gets "linkified(as seen below)")

Here is the message component.

I am trying to achieve a url preview for my Meteor + React app, where when users paste in a url in a textarea, they'll get a preview of the url. I plan to achieve this by using several npm modules i.e.:

1. url-regex, and
2. open-graph-scraper

I understand that in order to avoid any CORS issue, the request should be done server side. So I have this currently set up:

//on client

I use Angular 4 and have trouple using url-regex package in my Component.

In some cases, I have found out that this works:

I'm having hard time introducing UrlInput component in React. The main idea is to get props, like url and its setter (from parent) and split it internally into 3 UrlInput state values, e.g. protocol, host and port. UrlInput should use 3 form fields and change a single url in parent.

Simplified version:

I'm running Python app in AppEngine Standard Environment which is using Redis (Memorystore instance connected via VPC).

When I deploy a new version (meaning the value of version parameter for gcloud beta app deploy command) of the app, the VPC connection works fine. However when I redeploy the existing version again, the VPC connection stops working (Redis connnection times out: Error 110 connecting to xxx.xxx.xxx.xxx:6379. Connection timed out.)

The app has some Historical Reasons where it relies on a specific version name of the deployed version, plus it's using Canary Deployment (small percentage of traffic goes to new version) via the builtin AppEngine feature for splitting traffic, which has hardcoded version name too, so redeployment to Canary is unusable.

Obvious answer is fixing the Historical Reasons and deployment (which has low priority unfortunately), so is there any way how to fix/workaround this issue in the meantime?
