▸ get(): string

Gets the value associated with the key key in the KV store.

Syntax

get(key)

Parameters

• key : string
  • The key to retrieve from within the KV-store.

Return value

If the key does not exist in the KV store, this returns a Promise which resolves with null.

If the key does exist in the KV store, this returns a Promise which resolves with an KVStoreEntry.

Description

Send the given message, converted to a string, to this KVStore instance's endpoint.

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

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

Exceptions

• TypeError
  • If the provided key:
    • Is any of the strings "", ".", or ".."
    • Starts with the string ".well-known/acme-challenge/"
    • Contains any of the characters "#?*[]\n\r"

Examples

In this example we connect to an KV Store named 'files' and save an entry to the store under the key 'hello' and then read back the value and return it to the client.

/// <reference types="@fastly/js-compute" />

import { KVStore } from "fastly:kv-store";

async function app(event) {
  const files = new KVStore('files')

  await files.put('hello', 'world')

  const entry = await files.get('hello')

  return new Response(await entry.text())
}

addEventListener("fetch", (event) => event.respondWith(app(event)))
