@swishapp/node NPM

Swish app proxy for Node.js

The Swish browser library requires a proxy service that operates on the same domain as the store. This service facilitates the loading of additional resources and ensures secure communication with the Swish API.

Installation

npm i @swishapp/node

Usage

The example below is for Remix and needs to be adjusted for other frameworks.

import { ActionFunction, LoaderFunction } from "@remix-run/node";
import { createAppProxy, MemoryStorage } from "@swishapp/node";

const swishProxy = createAppProxy({
  basePath: "/swish", // Needs to match the route path
  authToken: process.env.SWISH_API_TOKEN,
  storage: new MemoryStorage(), // Use MemoryStorage for development only!
  authenticate: async (request) => {
    // Authenticate the request and return customer id or null
    // Throw an error if the request cannot be authenticted
    return null;
  },
  onError: (error) => {
    console.error(error);
  },
});

export const loader: LoaderFunction = async ({ request }) =>
  swishProxy.forward(request);

export const action: ActionFunction = async ({ request }) =>
  swishProxy.forward(request);

The Swish app for browsers won't work on the server. Use it as a client only script!

// The proxy also serves the Swish brwoser app
import { createApp } from "/swish/assets/swish.js"; // Assuming the proxy runs on /swish

const swish = await createApp({
  proxy: {
    baseUrl: "/swish", // Use proxy route path
  },
});
