Example
var hexColorRegex = require('hex-color-regex') hexColorRegex().test('#f3f}') //=> true hexColorRegex({strict: true}).test('#f3f}') //=> false hexColorRegex().test('foo #f3f bar') //=> true hexColorRegex({strict: true}).test('foo #f3f bar') //=> false hexColorRegex().test('#a54f2c}') //=> true hexColorRegex({strict: true}).test('#a54f2c}') //=> false hexColorRegex().test('foo #a54f2c bar') //=> true hexColorRegex({strict: true}).test('foo #a54f2c bar') //=> false hexColorRegex().test('#ffff') //=> false hexColorRegex().test('ffff') //=> false hexColorRegex().test('#fff') //=> true hexColorRegex().test('fff') //=> false hexColorRegex().test('#4g1') //=> false hexColorRegex().test('4g1') //=> false hexColorRegex().test('#zY1') //=> false hexColorRegex().test('zY1') //=> false hexColorRegex().test('#7f68ZY') //=> false hexColorRegex().test('7f68ZY') //=> false hexColorRegex().test('ffffff') //=> false hexColorRegex().test('#afebe3') //=> true hexColorRegex().test('#AFEBE3') //=> true hexColorRegex().test('#3cb371') //=> true hexColorRegex().test('#3CB371') //=> true hexColorRegex().test('#556b2f') //=> true hexColorRegex().test('#556B2F') //=> true hexColorRegex().test('#708090') //=> true hexColorRegex().test('#7b68ee') //=> true hexColorRegex().test('#7B68EE') //=> true hexColorRegex().test('#eeeeee') //=> true hexColorRegex().test('#ffffff') //=> true hexColorRegex().test('#111111') //=> true hexColorRegex().test('#afe') //=> true hexColorRegex().test('#AF3') //=> true hexColorRegex().test('#3cb') //=> true hexColorRegex().test('#3CB') //=> true hexColorRegex().test('#b2f') //=> true hexColorRegex().test('#5B2') //=> true hexColorRegex().test('#708') //=> true hexColorRegex().test('#68e') //=> true hexColorRegex().test('#7AF') //=> true hexColorRegex().test('#777') //=> true hexColorRegex().test('#FFF') //=> true hexColorRegex().test('#fff') //=> truematch[0]hex value with hash -#f3f3f3match[1]hex value without the hash -f3f3f3
Example
hexColorRegex().exec('foo #fff bar') //=> [ '#fff', 'fff', index: 4, input: 'foo #fff bar' ] hexColorRegex({strict: true}).exec('foo #fff bar') //=> null hexColorRegex().exec('foo #f3f3f3 bar') //=> [ '#f3f3f3', 'f3f3f3', index: 4, input: 'foo #f3f3f3 bar' ] hexColorRegex({strict: true}).exec('foo #f3f3f3 bar') //=> null- benz: Compose your control flow with absolute elegance.
