node-promise-retry

A module that encapsulates promise retry logic

Example usage:

1  ...
2  var retry = new Retry({
3    // max number of tries. 
4    maxTries: 2,
5    // the delay between each retries
6    delay : 500, 
7    // fires on every error
8    onError : function(error){
9        console.log(error);
10    },
11    // a promise factory function
12    promiseFactory: function () {
13        return new Promise(function(res,rej){
14            setTimeout(function(){
15                if(retry.getRetries()==2){
16                    res(true);
17                }else{
18                    rej(new Error("An error!"));
19                }
20            },100);
21        });
22    }
23});
24// execute 
25retry.execute().then(function(result){
26    console.log("Result : "+result);
27    console.log("Errors : ");
28    console.log(retry.getErrors());
29    console.log("Retries :" + retry.getRetries());
30}).catch(function(error){
31    console.log(error);
32});
