API Endpoints for helixml/demo-recipes

This documentation outlines the routes defined within the helixml/demo-recipes codebase. Understanding the routes is crucial for developers to navigate and utilize the application efficiently.

Overview of Routes

Routes in the helixml/demo-recipes codebase serve as the paths for navigating through different functionalities offered by the application. These routes are defined within the framework and serve various purposes, including rendering specific components and handling user interactions.

Identifying Routes in the Codebase

Routes are typically defined in a specific module or file. Developers can locate the route definitions by examining the relevant sections of the codebase. Below are examples demonstrating how to identify and understand the routes in this project.

Example Route Definitions

In a typical setup, routes may be defined in a module that handles routing. Below is a representative example demonstrating the structure of route definitions.

import { Router } from 'express';


const router = Router();


// Define a route for the homepage
router.get('/', (req, res) => {
res.send('Welcome to the Home Page');
});


// Define a route for recipes
router.get('/recipes', (req, res) => {
res.send('List of Recipes');
});


// Define a route for a specific recipe
router.get('/recipes/:id', (req, res) => {
const recipeId = req.params.id;
res.send(Recipe details for id: ${recipeId});
});


export default router;

In the above TypeScript example, several HTTP GET routes are defined:

  • The route / serves as the homepage.
  • The route /recipes returns a list of recipes.
  • The route /recipes/:id retrieves details of a specific recipe based on the provided ID.

Exploring Route with Parameters

Routes can also incorporate parameters to dynamically fetch data. This approach allows for flexible URL patterns while keeping the logic concise. The route defined as /recipes/:id illustrates this concept, where :id acts as a placeholder for a specific resource.

Middleware Usage

Routes can also utilize middleware to handle authentication, logging, or data validation. An example of a route using middleware is illustrated below:

import { Router } from 'express';
import { authenticateUser } from './middlewares/auth';


const router = Router();


// Route that requires authentication
router.get('/recipes', authenticateUser, (req, res) => {
res.send('Authenticated user - List of Recipes');
});

In this case, the authenticateUser middleware is invoked before the handler, ensuring that only authenticated users can access the /recipes route.

Static File Serving

Another important aspect of routing can include serving static files such as CSS or JavaScript. This is typically set up at the application level. An example route for serving static files can be structured as follows:

import express from 'express';
import path from 'path';


const app = express();


// Serve static files from the public directory
app.use('/public', express.static(path.join(__dirname, 'public')));

This setup allows users to access static files through the /public route, providing easy access to resources such as stylesheets and scripts.

Conclusion

This overview details the approach to defining and utilizing routes in the helixml/demo-recipes codebase. Routes are implemented using various methods, enabling organized and dynamic access to application features. Understanding these routes is essential for any developer working with this codebase.
