how to pull @ mentions out of strings like twitter in javascript

Question

I am writing an application in Node.js that allows users to mention each other in messages like on twitter. I want to be able to find the user and send them a notification.

Answer 1

here is how you extract mentions from instagram caption with JavaScript and underscore.

var _ = require('underscore');

function parseMentions(text) {
    var mentionsRegex = new RegExp('@([a-zA-Z0-9\_\.]+)', 'gim');

    var matches = text.match(mentionsRegex);
    if (matches && matches.length) {
        matches = matches.map(function(match) {
            return match.slice(1);
        });
        return _.uniq(matches);
    } else {
        return [];
    }
}
