Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.

handleDrop = files => {
  // Push all the axios request promise into a single array
  const uploaders = files.map(file => {
    // Initial FormData
    const formData = new FormData();
    formData.append("file", file);
    formData.append("tags", `codeinfuse, medium, gist`);
    formData.append("upload_preset", "pvhilzh7"); // Replace the preset name with your own
    formData.append("api_key", "1234567"); // Replace API key with your own Cloudinary key
    formData.append("timestamp", (Date.now() / 1000) | 0);

Problem

You have installed GPG, then tried to perform a git commit and suddenly you see this error message after it 😰

error: gpg failed to sign the data
fatal: failed to write commit object

Understand the error (important to solve it later!)
