+# retry-as-promised
+
+Retry promises when they fail, based upon [any-promise](https://github.com/kevinbeaty/any-promise).
+
+## Installation
+
+```sh
+$ npm install --save retry-as-promised
+$ yarn add retry-as-promised
+```
+
+## Configuration
+
+```js
+var retry = require('retry-as-promised');
+
+var warningFn = function(msg){ someLoggingFunction(msg, 'notice'); };
+
+// Will call the until max retries or the promise is resolved.
+return retry(function (options) {
+  // options.current, times callback has been called including this call
+  return promise;
+}, {
+  max: 3, // maximum amount of tries
+  timeout: 10000 // throw if no response or error within millisecond timeout, default: undefined,
+  match: [ // Must match error signature (ala bluebird catch) to continue
+    Sequelize.ConnectionError,
+    'SQLITE_BUSY'
+  ],
+  backoffBase: 1000 // Initial backoff duration in ms. Default: 100,
+  backoffExponent: 1.5 // Exponent to increase backoff each try. Default: 1.1
+  report: warningFn, // the function used for reporting; must have a (string, object) argument signature, where string is the message that will passed in by retry-as-promised, and the object will be this configuration object + the $current property
+  name:  'SourceX' // if user supplies string, it will be used when composing error/reporting messages; else if retry gets a callback, uses callback name in erroring/reporting; else (default) uses literal string 'unknown'
+});
+```
