Browser API's

peligro

This SDK is a Work In Progress! All features are subject to change.

By default, the WebWorks runtime in the browser does not provide direct access to localStorage or sessionStorage . These APIs are part of the main thread’s window context and are not natively available inside web workers.

To overcome this limitation and enable NubeSDK applications to use these storage APIs transparently, the NubeSDK includes an internal mechanism that exposes both localStorage and sessionStorage within the worker environment.

localStorage and sessionStorage​

The nube object exposes a method called getBrowserAPIs, which returns an interface with support for asynchronous access to browser APIs. These include asyncLocalStorage and asyncSessionStorage, which return promises for use within asynchronous contexts.

How to Use​

The next example uses the setItem method from asyncSessionStorage to store a new value.

main.ts
import type { NubeSDK } from "@tiendanube/nube-sdk-types";

export function App(nube: NubeSDK) {
    const browser = nube.getBrowserAPIs();

    browser.asyncSessionStorage.setItem("my_custom_field", "Hello World!").then(() => {
        console.log("Item set in async session storage");
    });
}

The next example uses the getItem method from asyncSessionStorage to retrieve a stored value.

main.ts
import type { NubeSDK } from "@tiendanube/nube-sdk-types";

export function App(nube: NubeSDK) {
    const browser = nube.getBrowserAPIs();

    browser.asyncSessionStorage.getItem("my_custom_field").then((value) => {
        console.log("my_custom_field", value);
    });
}

Time To Live​

Both asyncLocalStorage and asyncSessionStorage support an optional third parameter called ttl (time-to-live), which defines how long the stored value should remain valid, in seconds.

When provided, the ttl determines the expiration time for the key. Once the specified duration has passed, the value will no longer be accessible via getItem, and it will be treated as if it were removed.

main.ts
// Store a value that expires in 60 seconds
await browser.asyncLocalStorage.setItem("my_custom_field", "Hello World!", 60);

If no ttl is provided, the value will persist indefinitely, following the default behavior of localStorage and sessionStorage.
