Optimizing Performance

There are many approaches to optimize performance when interacting with Drupal’s JSON:API endpoints. This guide will cover some of the most common strategies.

Caching data

When creating an instance of the client, it is possible to provide a cache to store data returned from JSON:API . This can have a big impact on performance, especially in cases when the same data is requested multiple times.

Using the default cache

For a simple way to cache responses, the API Client provides a default cache based on the Nanostores library. To use it, create an instance of the cache using the createCache function and pass it to the client when creating an instance.

Umami Recipes

• Deep mediterranean quiche
• Vegan chocolate and nut brownies
• Super easy vegetarian pasta bake
• Watercress soup
• Victoria sponge cake
• Gluten free pizza
• Thai green curry
• Crema catalana
• Fiery chili sauce
• Borscht with pork ribs

import { JsonApiClient, createCache } from "@drupal-api-client/json-api-client";

const client = new JsonApiClient(
  "https://drupal-api-demo.party", {
    cache: createCache(),
  }
);
const recipes = await client.getCollection("node--recipe");
---
<h2>Umami Recipes</h2>
<ul>
  {recipes.data.map((recipe) => (
    <li key={recipe.id}>{recipe.attributes.title}</li>
  ))}
</ul>

The first call to getCollection will fetch the data from the server and store it in the cache. Subsequent calls to getCollection for node--recipe will return the data from the cache, which can significantly reduce the number of requests made to the server.

Using a custom cache

In addition to the default cache, an alternative cache can be used. The provided cache needs to be compatible with the ApiClient cache interface. This interface expects the cache to have get and set methods.

As an example, let’s look at how we could use the node-cache package.

---
import { JsonApiClient } from "@drupal-api-client/json-api-client";
import NodeCache from "node-cache";

const client = new JsonApiClient(
  "https://drupal-api-demo.party", {
    cache: new NodeCache(),
  }
);
const recipes = await client.getCollection("node--recipe");
---
<h2>Umami Recipes</h2>
<ul>
  {recipes.data.map((recipe) => (
    <li key={recipe.id}>{recipe.attributes.title}</li>
  ))}
</ul>
