Full-Stack React Projects

Overview of this book

The benefits of using a full JavaScript stack for web development are undeniable, especially when robust and widely adopted technologies such as React, Node, and Express and are available. Combining the power of React with industry-tested, server-side technologies, such as Node, Express, and MongoDB, creates a diverse array of possibilities when developing real-world web applications. This book guides you through preparing the development environment for MERN stack-based web development, to creating a basic skeleton application and extending it to build four different web applications. These applications include a social media, an online marketplace, a media streaming, and a web-based game application with virtual reality features. While learning to set up the stack and developing a diverse range of applications with this book, you will grasp the inner workings of the MERN stack, extend its capabilities for complex features, and gain actionable knowledge of how to prepare MERN-based applications to meet the growing demands of real-world web applications.

Product search with category


In MERN Marketplace, visitors will be able to search for specific products by name and also in a specific category.

Categories API

To allow users to select a specific category to search in, we will set up an API that retrieves all the distinct categories present in the Product collection in the database. A GET request to /api/products/categories will return an array of unique categories.

mern-marketplace/server/routes/product.routes.js:

router.route('/api/products/categories')
      .get(productCtrl.listCategories)

The listCategories controller method queries the Product collection with a distinct call against the category field.

mern-marketplace/server/controllers/product.controller.js:

const listCategories = (req, res) => {
  Product.distinct('category',{},(err, products) => {
    if (err) {
      return res.status(400).json({
        error: errorHandler.getErrorMessage(err)
      })
    }
    res.json(products)
  })
}

This categories API can be used in the frontend...
