Question

Is this safe to use require(\"path\").join to concatenate URLs, for example:

//returns          


        

Answer 1

My solution

path.join(SERVER_URL, imageAbsolutePath).replace(':/','://');

Edit: if you want to support windows enviroments

path.join(SERVER_URL, imageAbsolutePath).replace(/\\/g,'/').replace(':/','://');

The second solution will replace all the backslashes, so url parts like querystring and hash may be altered too, but the topic is joining just the url path, so I don't consider it an issue.
