ConfigStore.prototype.get

The get() method returns the value associated with the provided key in the config-store. If the provided key does not exist in the ConfigStore then this returns null.

Syntax​

get(key)

Parameters​

  • key : string
    • The key to retrieve from the dictionary.

Return value​

A string representing the specified ConfigStore value or null if the key does not exist in the ConfigStore

Description​

Get a value for a key in the config-store. If the provided key does not exist in the ConfigStore then this returns null.

The get() method requires its this value to be a ConfigStore object.

If the this value does not inherit from ConfigStore.prototype, a TypeError is thrown.

Exceptions​

  • TypeError
    • Thrown if the provided key is longer than 255 in length
    • Thrown if the provided key is an empty string

Examples​

In this example we have an Edge Dictionary named "animals" and we return the "cat" entry as the response body to the client.

/// <reference types="@fastly/js-compute" />
import { ConfigStore } from "fastly:config-store";
async function app (event) {
  const config = new ConfigStore('animals');
  return new Response(config.get('cat'));
}
addEventListener("fetch", event => event.respondWith(app(event)));
