I'm using JekyllCMS to develop a Content Management System (CMS), but as I do not know it very well and even after reading the documentation, I find it hard to "hide" some of the data I use in JavaScript . There are two cases:% of the Graph API and key of the < a href="https://mandrillapp.com/"> Mandrill . I use these two keys in my code to acquire feed from a particular Facebook page and redirect e-mails to a particular mailbox. How can I deprive the end user of access to these keys ?
