Useful regular expressions for JavaScript

Install

npm install --save regs

Usage

Node

const regs = require('regs');

regs.email().test('me@gmail.com');
//=> true

regs.yeoman().exec('<% var1 %>')[1]
//=> 'var1'

Web

<script src="https://rawgit.com/dawsonbotsford/regs/master/bundle.js"></script>
<script>
  alert(regs.trim().exec(' var1 ')[1]);
  //=> 'var1'
</script>

Supported regexp types

• yeoman (regs.yeoman())
• trim (regs.trim())
• email (regs.email())

API

• Each function call returns a RegExp object which can then operate on/with.

• Each function call supports (optionally) the official RegExp flags which alter behavior of the search. (ex: 'g' for global or 'i' to ignore case)

regs.yeoman([RegExpFlags])

Capture text between <% %> or <%= %>.

1 capture group - the value between delimeters.

Example:

regs.yeoman().exec('<% capture this %>')[1];
//=> 'capture this'

regs.trim([RegExpFlags])

Capture text without surrounding spaces.

1 capture group - the value between starting and ending spaces.

Example:

regs.trim().exec(' var1 ')[1];
//=> 'var1'

regs.email([RegExpFlags])

Capture all three parts of an email address. Example:

3 capture groups -

1. Name before @
2. First part of the domain (between @ and .)
3. Domain suffix (.com, .io, etc.)

Example:

// Simple validation
regs.email().test('name@domain.suffix');
//=> true

// Capture all parts
regs.email().exec('hi@me.io');
//=> [ 'hi@me.io', 'hi', 'me', 'io', index: 0, input: 'hi@me.io' ]
