In today's post we will learn about 10 Favorite JavaScript String Libraries.
There are different ways to manipulate strings, look up parts of a string in various positions, and trim and replace strings. With each release of the JavaScript specification, more methods are added to make string search and manipulating easier than ever. So in this post I’ve collected some Javscript libraries that will make working with strings easy for developers.
Table of contents:
Voca is a JavaScript library for manipulating strings. https://vocajs.com
v.camelCase('bird flight'); // => 'birdFlight'
v.sprintf('%s costs $%.2f', 'Tea', 1.5); // => 'Tea costs $1.50'
v.slugify('What a wonderful world'); // => 'what-a-wonderful-world'
The Voca library offers helpful functions to make string manipulations comfortable: change case, trim, pad, slugify, latinise, sprintf'y, truncate, escape and much more. The modular design allows to load the entire library, or individual functions to minimize the application builds. The library is fully tested, well documented and long-term supported.
Voca can be used in various environments.
Install the library with npm into your local modules directory:
npm install voca
Then in your application require the entire library:
const v = require('voca');
v.trim(' Hello World! '); // => 'Hello World'
v.sprintf('%d red %s', 3, 'apples'); // => '3 red apples'
Or require individual functions:
const words = require('voca/words');
const slugify = require('voca/slugify');
words('welcome to Earth'); // => ['welcome', 'to', 'Earth']
slugify('caffé latté'); // => 'caffe-latte'
A library that allows you to access the text selected by the user.
To install Selecting, execute:
npm install selecting
Or Bower too:
bower install selecting
Or simply pick up the file from src directory.
Javascript lacks complete string manipulation operations. This is an attempt to fill that gap. List of build-in methods can be found for example from Dive Into JavaScript. Originally started as an Underscore.js extension but is a full standalone library nowadays.
Upgrading from 2.x to 3.x? Please read the changelog.
Install from npm
npm install underscore.string
Require individual functions
var slugify = require("underscore.string/slugify");
slugify("Hello world!");
// => hello-world
or load the full library to enable chaining
var s = require("underscore.string");
s(" epeli ").trim().capitalize().value();
// => "Epeli"
but especially when using with Browserify the individual function approach is recommended because using it you only add those functions to your bundle you use.
From your Meteor project folder
meteor add underscorestring:underscore.string
and you'll be able to access the library with the s global from both the server and the client.
s.slugify("Hello world!");
// => hello-world
s(" epeli ").trim().capitalize().value();
// => "Epeli"
string.js
, or simply S
is a lightweight (< 5 kb minified and gzipped) JavaScript library for the browser or for Node.js that provides extra String methods. Originally, it modified the String prototype. But I quickly learned that in JavaScript, this is considered poor practice.
If you want to use this library, you first need to install the [Node.js] (https://nodejs.org/en/).
When you install node.js, will also be installed [npm] (https://www.npmjs.com/).
Please run the following command.
npm install --save string
Assuming you're on http://stringjs.com, just simply open up the Webkit inspector in either Chrome or Safari, or the web console in Firefox and you'll notice that string.js
is included in this page so that you can start experimenting with it right away.
var S = require('string');
Originally, I was using $s
but glancing over the code, it was easy to confuse $s
for string.js with $
for jQuery. Feel free to use the most convenient variable for you.
Checkout this gem to easily use string.js on the asset pipeline: https://github.com/jesjos/stringjs-rails
<!-- HTML5 -->
<script src="https://cdn.rawgit.com/jprichardson/string.js/master/dist/string.min.js"></script>
<!-- Note that in the mime type for Javascript is now officially 'application/javascript'. If you
set the type to application/javascript in IE browsers, your Javacript will fail. Just don't set a
type via the script tag and set the mime type from your server. Most browsers look at the server mime
type anyway -->
<!-- For HTML4/IE -->
<script type="text/javascript" src="https://cdn.rawgit.com/jprichardson/string.js/master/dist/string.min.js"></script>
A global variable window.S
or simply S
is created.
he (for “HTML entities”) is a robust HTML entity encoder/decoder written in JavaScript. It supports all standardized named character references as per HTML, handles ambiguous ampersands and other edge cases just like a browser would, has an extensive test suite, and — contrary to many other JavaScript solutions — he handles astral Unicode symbols just fine. An online demo is available.
Via npm:
npm install he
Via Bower:
bower install he
Via Component:
component install mathiasbynens/he
In a browser:
<script src="he.js"></script>
In Node.js, io.js, Narwhal, and RingoJS:
var he = require('he');
In Rhino:
load('he.js');
Using an AMD loader like RequireJS:
require(
{
'paths': {
'he': 'path/to/he'
}
},
['he'],
function(he) {
console.log(he);
}
);
const str = '' +
'<!doctype html>' +
'<html>' +
' <body>' +
' <h1>❤ unicorns</h1>' +
' </body>' +
'</html>' +
'';
const str = multiline(()=>{/*
<!doctype html>
<html>
<body>
<h1>❤ unicorns</h1>
</body>
</html>
*/});
It works by wrapping the text in a block comment, anonymous function, and a function call. The anonymous function is passed into the function call and the contents of the comment extracted.
Even though it's slower than string concat, that shouldn't realistically matter as you can still do 2 million of those a second. Convenience over micro performance always.
$ npm install multiline
$ npm install query-string
Not npm install querystring
!!!!!
This module targets Node.js 6 or later and the latest version of Chrome, Firefox, and Safari.
const queryString = require('query-string');
console.log(location.search);
//=> '?foo=bar'
const parsed = queryString.parse(location.search);
console.log(parsed);
//=> {foo: 'bar'}
console.log(location.hash);
//=> '#token=bada55cafe'
const parsedHash = queryString.parse(location.hash);
console.log(parsedHash);
//=> {token: 'bada55cafe'}
parsed.foo = 'unicorn';
parsed.ilike = 'pizza';
const stringified = queryString.stringify(parsed);
//=> 'foo=unicorn&ilike=pizza'
location.search = stringified;
// note that `location.search` automatically prepends a question mark
console.log(location.search);
//=> '?foo=unicorn&ilike=pizza'
Parse a query string into an object. Leading ?
or #
are ignored, so you can pass location.search
or location.hash
directly.
The returned object is created with Object.create(null)
and thus does not have a prototype
.
Type: object
decode
Type: boolean
Default: true
Decode the keys and values. URL components are decoded with decode-uri-component
.
I always want to shoot myself in the head when looking at code like the following:
var url = "http://example.org/foo?bar=baz";
var separator = url.indexOf('?') > -1 ? '&' : '?';
url += separator + encodeURIComponent("foo") + "=" + encodeURIComponent("bar");
Things are looking up with URL and the URL spec but until we can safely rely on that API, have a look at URI.js for a clean and simple API for mutating URIs:
var url = new URI("http://example.org/foo?bar=baz");
url.addQuery("foo", "bar");
URI.js is here to help with that.
// mutating URLs
URI("http://example.org/foo.html?hello=world")
.username("rodneyrehm")
// -> http://rodneyrehm@example.org/foo.html?hello=world
.username("")
// -> http://example.org/foo.html?hello=world
.directory("bar")
// -> http://example.org/bar/foo.html?hello=world
.suffix("xml")
// -> http://example.org/bar/foo.xml?hello=world
.query("")
// -> http://example.org/bar/foo.xml
.tld("com")
// -> http://example.com/bar/foo.xml
.query({ foo: "bar", hello: ["world", "mars"] });
// -> http://example.com/bar/foo.xml?foo=bar&hello=world&hello=mars
// cleaning things up
URI("?&foo=bar&&foo=bar&foo=baz&")
.normalizeQuery();
// -> ?foo=bar&foo=baz
// working with relative paths
URI("/foo/bar/baz.html")
.relativeTo("/foo/bar/world.html");
// -> ./baz.html
URI("/foo/bar/baz.html")
.relativeTo("/foo/bar/sub/world.html")
// -> ../baz.html
.absoluteTo("/foo/bar/sub/world.html");
// -> /foo/bar/baz.html
// URI Templates
URI.expand("/foo/{dir}/{file}", {
dir: "bar",
file: "world.html"
});
// -> /foo/bar/world.html
See the About Page and API Docs for more stuff.
Lightweight URL manipulation with JavaScript for both DOM and server JavaScript.
To have a convenient way working with URLs in JavaScript. From time to time there are usual tasks when it is required to add or remove some parameters to some basic URL or change some other URL parts.
There is no easy standard way to do it in JavaScript.
This small library intended to fix that problem
First of all it is required to include Url class on the page. It can be simply done as
<script src="url.min.js"></script>
Then any time it's required to do some work over the URL string, it's just required to instantiate the Url object and work with that object instead of initial string. See API description below to get a clue.
It is possible also to install domurl via JAM repository (http://jamjs.org/). Could be simply done as:
$ jam install domurl
It is also possible now to install domurl using Bower package repository. Could be done simply as:
$ bower install domurl
Domurl is available on NPM and is now works well for both server and browser:
$ npm install domurl
sprintf-js is a complete open source JavaScript sprintf
implementation for the browser and Node.js.
Note: as of v1.1.1 you might need some polyfills for older environments. See Support section below.
var sprintf = require('sprintf-js').sprintf,
vsprintf = require('sprintf-js').vsprintf
sprintf('%2$s %3$s a %1$s', 'cracker', 'Polly', 'wants')
vsprintf('The first 4 letters of the english alphabet are: %s, %s, %s and %s', ['a', 'b', 'c', 'd'])
npm install sprintf-js
bower install sprintf
sprintf
Returns a formatted string:
string sprintf(string format, mixed arg1?, mixed arg2?, ...)
vsprintf
Same as sprintf
except it takes an array of arguments, rather than a variable number of arguments:
string vsprintf(string format, array arguments?)

String methods in JavaScript help you to work with strings, mastering those methods is a good idea, because a lot of times you will find yourself working with strings in your JavaScript program or application, So you will need to know those methods. That’s why in this article I decided to show you 10 useful string methods that maybe you didn’t know some of them.
Photo by Irvan Smith on Unsplash
The **length**
property returns the length of a string. Take a look at the example below:
The Length method.
You can search for a string inside another string using the search method, It will return the position of that string. Have a look at the example below:
The Search method.

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.
JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.
JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.
Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.
In JavaScript, ‘document.write‘ is used to represent a string on a browser.
<script type="text/javascript">
document.write("Hello World!");
</script>
<script type="text/javascript">
//single line comment
/* document.write("Hello"); */
</script>
#javascript #javascript code #javascript hello world #what is javascript #who invented javascript
