An API in node.js to take a count of page hits and things like that for my web projects.
The script is designed to have multiple counters running at once - simply create a .json file in the data directory for each one. To increment the counter by one, submit a POST request to http://device-ip:3131/json-file-name. Remember not to include the .json of the file in the json-file-name part, just it's raw name.
To receive the number of a counter, just retreive it with a GET request from http://device-ip:3131/json-file-name in the form of UTF-8 plaintext.
