- 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.
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 } }) - Currently uses
module.exports, should probably use ES6export
- see parse-retry-after6.mjs for first pass at an ES6 export.
