Licences – string functions

Licences for used library for string operation

Simple lightweight string operation library for Typescript.

No jQuery required! Unit tested, works with Angular.

 import { String, StringBuilder } from 'typescript-string-operations';

USAGE:

String.Empty

var id = String.Empty;

String.IsNullOrWhiteSpace():

var id = image.GetId();
if(String.IsNullOrWhiteSpace(id))
	return image;

String.Format():

var id = image.GetId()
String.Format("image_{0}.jpg", id)
output: "image_2db5da20-1c5d-4f1a-8fd4-b41e34c8c5b5.jpg";

Specifier available!

var value = String.Format("{0:L}", "APPLE"); //output "apple"

value = String.Format("{0:U}", "apple"); // output "APPLE"

value = String.Format("{0:d}", "2017-01-23 00:00"); //output "23.01.2017"


value = String.Format("{0:s}", "21.03.2017 22:15:01") //output "2017-03-21T22:15:01"

value = String.Format("{0:n}", 1000000);
//output "1.000.000"

value = String.Format("{0:00}", 1);
//output "01"

UPDATE

String Format for Objects including specifiers

var fruit = new Fruit();
fruit.type = "apple";
fruit.color = "RED";
fruit.shippingDate = new Date(2018, 1, 1);
fruit.amount = 10000;

String.Format("the {type:U} is {color:L} shipped on {shippingDate:s} with an amount of {amount:n}", fruit);
// output: the APPLE is red shipped on 2018-01-01 with an amount of 10.000

String.Join():

var value = String.Join("; ", "Apple", "Banana");
//output: "Apple; Banana";

OR

 let object = { Name: "Foo", Value: "Bar" };
 var value = String.Join('.', object);
//output: "Foo.Bar";

var array = ['Apple', 'Banana']
var value = String.Join("; ", array);
//output: "Apple; Banana";

Methods

StringBuilder

Just like you know from C#,

var favoriteFruit: string = this.fruitService.getFavorite(); //Blueberries

var builder = new StringBuilder("My favorite fruits are: ");
builder.Append("Apples, ");
builder.Append("Bananas ");

// of course using String.Format()
builder.AppendFormat("and especially {0:U}!", favoriteFruit);
builder.AppendFormat(" I eat {0} every day!", 10);

var fruits = builder.ToString();

//output: "My favorite fruits are: Apples, Bananas and especially BLUEBERRIES! I eat 10 every day!";
