request-promise-retry

npm : promise-request-retry

Simple wrapper on top of request-promise to replicate retry mechanism, i.e, it will try to reprocess the request till a valid response is obtained, or the number of retrys is exhausted. Supports all options from request-promise.

Usage

• additional parameter retry needed in request-promise options.
• retry supports boolean (defaults to 1 retry) and positive integer.
• in order to ignore retry or use genericrequest-promise,just don't specify the retry parameter.

GET Request sample with retry

var rp = require('promise-request-retry');
var options = {
    uri: 'https://api.github.com/user/repos',
    qs: {
        access_token: 'xxxxx xxxxx' // -> uri + '?access_token=xxxxx%20xxxxx'
    },
    headers: {
        'User-Agent': 'Request-Promise'
    },
    json: true // Automatically parses the JSON string in the response, 
    retry : 2 // will retry the call twice, in case of error.
    verbose_logging : false // will log errors only, if set to be true, will log all actions
};

rp(options)
    .then(function (repos) {
        console.log('User has %d repos', repos.length);
    })
    .catch(function (err) {
        // API call failed...
    });
