Installation

npm install browser-storage-adapter --save

Usage

Create an instance of the Adapter and specify the drivers, which should be enabled. By default, all drivers are disabled, expect of the in-memory driver, which is always enabled.

Besides, it is also possible to specify a custom namespace, so different instances of the Adapter don't interfere with each other, when they use the same key.

import { Adapter } from 'browser-storage-adapter';

const warehouse = new Adapter({
    driver: {
        cookie: {
            path: '/',
        },
        localStorage: true,
        sessionStorage: true,
    },
    namespace: 'auth'
});

// Set a key-value pair for the following drivers:
// cookie, localStorage & sessionStorage.
warehouse.set('token', 'xxx');

// Ensure that value is still the same for all drivers.
warehouse.sync('token', 'xxx');

// Get a key-value pair.
const token = warehouse.get('token');
console.log(token);
// xxx

Options

The Adapter accepts an OptionsInput object as input parameter, to modify the default behaviour.

import { CookieSerializeOptions } from 'cookie';

declare type OptionsInput = {
    /**
     * Specify a key prefix.
     * e.g.
     *  namespace: auth
     *  key: token
     *  keyWithNamespace: auth_token
     */
    namespace?: string,
    /**
     * Enable or disable some available drivers.
     */
    driver?: {
        localStorage?: boolean,
        sessionStorage?: boolean,
        cookie?: boolean | CookieSerializeOptions
    },
    /**
     * Check if the application is server rendered.
     */
    isServer?: () => boolean,

    /**
     * Set cookie.
     *
     * @param key
     * @param value
     */
    setCookie?: (key: string, value: unknown) => void,

    /**
     * Get cookie.
     *
     * @param key
     */
    getCookie?: (key: string) => unknown,

    /**
     * Append serialized cookie.
     *
     * @param value
     */
    setServerCookie?: (value: string) => void,
    /**
     * Ger serialized cookie(s).
     */
    getServerCookies?: () => string
}
