GraphQL Rate Limit - Points Calculator

This example illustrates customizing how many points are consumed in different resolver situations.

Overview

Specify a pointsCalculator function which uses contextual information from the resolver's info and context.

Setup

Step 1: Install requirements

yarn install

Run

Step 1: Start server

node index.js

Step 2: Open GraphiQL

Navigate to http://localhost:4000/graphql in a browser.

Step 3: Execute GraphQL operations

Server is configured to allow the following queries:

• quote: 10 times every 30 seconds (due to defaultPointsCalculator)
• books: 5 times every 30 seconds (due to cost of 2) or unlimited times when the GraphQL API endpoint includes query string token=secret (e.g. http://localhost:4000/graphql?token=secret)

Sample query:

{
  quote
  books {
    title
    author
  }
}
