refs #5942, #6150 There were a few key problems I was looking to solve with this: - Introduce a single point of truth for what the URL for accessing the API should be - Provide a simple way to configure the utility (much like a true SDK) As of this commit, this utility is still automatically available in a Ghost theme. To use it on an external site, the code would look like: ``` <script type="text/javascript" src="http://my-ghost-blog.com/shared/ghost-url.min.js"></script> <script type="text/javascript"> ghost.init({ clientId: "<your-client-id>", clientSecret: "<your-client-secret>" }); </script> ``` To achieve this, there have been a number of changes: - A new `apiUrl` function has been added to config, which calculates the correct URL. This needs to be unified with the other url generation functions as a separate piece of work. - The serveSharedFile middleware has been updated, so that it can serve files from / or /shared and to substitute `{{api-url}}` as it does `{{blog-url}}`. - ghost-url.js and ghost-url.min.js have been updated to be served via the serveSharedFile middleware - ghost-url.js has been changed slightly, to take the url from an inline variable which is substituted the first time it is served - `{{ghost_head}}` has been updated, removing the api url handling which is now in config/url.js and removing the configuration of the utility in favour of calling `init()` after the script is required - `{{ghost_head}}` has also had the meta tags for client id and secret removed - tests have been updated
