Has your app ever encountered a 429 (Too Many Requests) status code when making requests to a third-party API? Getting rate limited can be a nussance and if not handled properly can cause a bad experience for you and your users. While one solution is to catch the exception and ignore it, a better solution is to retry the request.

Let's take a look at how we can alleviate rate-limiting woes by utilizing a background job system. In this example we'll use delayed_job, since it provides the ability to retry failed jobs.

Let's pretend that we are going to be accessing the API of a popular website. Let's setup a background job that makes a request to that API.

class MyCustomJob < Struct.new(:param1, :param2)
  def perform
 PopularSiteApi.get('/posts')

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.
