Cloudflare Adds Security.txt Setup Wizard
Cloudflare has launched a setup wizard allowing users to easily create and manage a security.txt file for vulnerability disclosure on their websites.
coordinate-parser
Advanced tools
Flexible algorithm to parse strings containing various latitude/longitude formats.
Coordinates = require('coordinate-parser');
position = new Coordinates('40:7:22.8N 74:7:22.8W');
latitude = position.getLatitude(); // 40.123 ✓
longitude = position.getLongitude(); // -74.123 ✓
40.123, -74.123
40.123° N 74.123° W
40° 7´ 22.8" N 74° 7´ 22.8" W
40° 7.38’ , -74° 7.38’
N40°7’22.8, W74°7’22.8"
40°7’22.8"N, 74°7’22.8"W
40 7 22.8, -74 7 22.8
40.123 -74.123
40.123°,-74.123°
144442800, -266842800

40.123N 74.123W
40° 7.38, -74° 7.38
... and others that follow a similar pattern.
Handles also the following "exotic" formats:
145505994.48, -268708007.88
(geographical milliseconds)4025.0999N7438.4668W
(DDMM.xxxx)402505.994N743828.008W
(DDMMSS.xxxx)Input that does not resemble valid coordinates will throw an error.
The parser will detect invalid formats such as 40.123N FOOBAR 74.123W
(invalid characters), 40.123W 74.123N
(latitude/longitude exchanged) and 40.12 12.34 74.12
(odd numbers).
Flexibility towards non-alphanumeric characters and whitespaces is maintained.
isValidPosition = function(position) {
var error;
var isValid;
try {
isValid = true;
new Coordinates(position);
return isValid;
} catch (error) {
isValid = false;
return isValid;
}
};
isCoordinate = isValidPosition('40:7:22.8N 74:7:22.8W'); // true
isCoordinate = isValidPosition('40.123 FOOBAR! 74.123'); // false
