This article is part III of the series on Exploring GraphQL. In this article, we are going to build a GraphQL server for food ordering system using NodeJS and Express. This article assumes that you know the fundamental concepts of GraphQL like the use of Query, Mutations, Type System, Alias, Variables, Directives, and Fragments. If you have not heard of these topics before, it is always a good idea to go through the basics and then build something interesting out of it! I recommend reading the first and the second part of the series before heading over to the implementation part.

If you have been following along from the start of the series, you might already be familiar with most of the basic concepts used in GraphQL.

Let’s recap all that we have learned until now in the first and the second part of the series:

  1. Representational State Transfer (REST) is used for transferring resources across web services. It is being used extensively as a means of data transfer in a variety of applications. But as the complexity of the applications increased, people started experiencing some problems with REST. The REST way of transferring resources to the client is not scalable and has issues such as multiple endpoints, over-fetching, and under-fetching of resources and versioning.
  2. Facebook built GraphQL as an application layer to power up the data for the news feed section of its IOS application. GraphQL is a strong-typed declarative way of fetching only the required fields from the server. The client has full control over the data with GraphQL. The GraphQL server sends back the response in the exact same shape as requested by the client.
  3. GraphQL is just a specification that is used to define how clients can communicate with the server using its strict Type System. The client tells the format of the data to the server using queries. The GraphQL Type System supports scalar types, object types, and enums.
  4. We can pass arguments to the GraphQL queries for the root as well as the nested fields. We can also use Variables for passing dynamic data from the client. Mutations are used for causing side-effects on the server.

Now that we are all good with the GraphQL fundamentals, it’s time to build something. Let’s get to it right away!

How to Build Apollo GraphQL Server From Scratch

What is GraphQL

GraphQL is a query language and a server-side runtime that is used to request data from the server. The first thing that comes to mind when hearing the term “query language” is SQL. Just as SQL is used for querying databases, GraphQL is a bit like SQL but for querying web APIs as it eliminates the need to repeatedly develop or change existing end-points. GraphQL also enables the client/front-end to retrieve exactly the data they have requested and no more. This means that, within a single request of GraphQL, you can traverse from the entry point to the related data (whereas in RESTful API you have to call multiple endpoints to fetch similar results).

The following example will help you to understand this better. Let us consider an object person which has the attributes name, age, email, and contactNumber. Suppose the front-end only needs the name and age of the person. If we design a REST API, the endpoint will look like api/persons, which will end up fetching all the fields for the person object. The issue arises here because there is no easy way to communicate that I am interested in some fields and not others (which causes REST API to over fetch the data).

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.
