In some old Angular apps, I made use of the isNumeric function in RXJS.
I could import it:
And then use it:
2 // do stuff
3}
Unfortunately, isNumeric was hidden in RXJS. And seems completely gone in RXJS 7. I discovered this when updating an app for Angular 13.
In my use case I only cared about whether the input was an integer or not, so did not care about the other values. I was able to use native JavaScript to validate if my input string was an Integer or not::
2 // do stuff
3}
There is a bunch going on here. First, I converted the myStringValue to a String. The TypeScript compiler wanted me to do this. Then I use parseInt() to turn the string into an integer. From there, I can use Number.isInteger().
This has been working surprisingly well for my use case even if it isn't a direct replacement for the isNumeric functionality.
