# parse-retry-after

### Parses an HTTP Retry-After header and returns delay time in seconds.

- If there is no Retry-After header, returns 0

- If there is, returns **seconds** to delay, rounding up, **minimum 1**

- If Retry-After header is not an integer or a Date, (should not happen) throws an Error.

### Usage  (very rough, your code will differ!)

    const parse_retry_after = require('parse-retry-after');  // or import...

    fetch(URL, init)

      .then(function(response) {

        // probably want to save response somewhere somehow...

        // check response.status

        if (mightBeARetry) {

           let delaySeconds = parse_retry_after(response);

           if (delaySeconds) {

              //delay and call fetch again...

           }

        }

        else {

          // normal "happy path" code

        }

      })

### Todos

 1. Currently uses `module.exports`, should probably use ES6 `export`

 - see parse-retry-after6.mjs   for first pass at an ES6 export.
