rlajax

Rate Limited Ajax Handler

I made this library because I was maintaining a very old case management platform that had sprawled in an uncorrdinated fashion. The async calls to the backend had scaled out overtime to the point where a units of functionality would break other units of functionality or cause random page loads and server timeouts.

Usage

Instantiate

Instantiate an rlajax object. Pass an options object as described below:

• interaval - the cooldown time for a handler before it handles the next request in the stack.
• handlers - the number of handlers pulling from the stack of requests.
• timer - the regulator for the number of active requests allowed in a given period of time.
• logger - flag to print statements to the console

let obj = new rlajax({
    interaval: 2000,
    handlers: 3,
    timer: 60000,
    logger: true
});

Adding a request

obj.stack.push({
    url: "https://example.com",
    type: "GET",
    success: function (response) {
        console.log(response)
    }
});

Sending requests

obj.run();
