To add middleware to Shopify app routes, you can use the built-in middleware provided by the Express.js framework that Shopify apps are built on.


Here is an example of how you can add middleware to a route in a Shopify app:

  1. Create a new middleware function:
1
2
3
4
5
const myMiddleware = (req, res, next) => {
  // Do something before the route handler
  console.log('Middleware executed');
  next();
};


  1. Register the middleware function in your app's main file (index.js or server.js):
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
const express = require('express');
const app = express();

// Register the middleware globally to apply to all routes
app.use(myMiddleware);

// Define your route handlers
app.get('/my-route', (req, res) => {
  res.send('Hello World');
});

// Start the server
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});


  1. Now, when you send a request to the '/my-route' endpoint, the middleware function will be executed before the route handler function. You can add additional logic to the middleware function, such as checking authorization, logging, or modifying the request object before passing it to the route handler.


This is a basic example of how to add middleware to a Shopify app route. You can also use third-party middleware packages or write custom middleware functions to suit your specific needs.
