These days REST API has become a web applications development standard, allowing to divide web development into two separate parts. There are several mainstream frameworks like Angular, React, Vue, that are used for UI. Backend developers are free to choose from large variety of languages and frameworks. Today I’d like to discuss NestJS framework. We’re going to create a simple CRUD application using Nest and the @nestjsx/crud package.

First of all, a brief overview of our use case. Let's say I have a spreadsheet on Google Sheets which is not public and I want to be able to read/modify programmatically through some batch process running on my local machine or some server. This is something I had to do recently with a Node.js application and I found the authentication part a bit tricky to understand. So I thought of sharing my solution and I hope it helps someone in need. There might be better ways of doing this but I am sharing what worked best for me.

Learning MongoDB has been one of the things in my checklist for the past 6 months but hasn’t gotten around actually learning it until now. In order to understand writing queries and all I figured it’ll be better to make something instead of just reading and watching some tutorials. So, I’ve decided to make a user registration API i.e, a simple registration form kinda thing with only sign up and sign in functions as of now. As learning Mongo was the main intention, I’ve decided just to make the core app which is the backend functionality and no front end as it’s not necessary and I hate to do it.

When I was recently working in one of the client projects, I had to communicate with external MariaDB server to store records from React/Rails app, that means I would get ActiveRecord hash from our app which I had to convert to pure SQL query and send it to an external server for storing.

Long lines and long wait times frustrate guests and discourage them from returning to your restaurant. World-famous restaurants have come up with innovative ideas to eliminate these sources of frustration. Take McDonald’s as an example: In 2015, they started adopting self-service ordering kiosks that let customers select items, customize orders, and pay. Another good example is Stabucks. They built an app that lets customers order and pay in advance, then pick up their orders at their convenience. Those are just two examples, but there are many more.

Front-end seems to be one of the most popular developers’ niche over the last years. Front-enders create the front view of the web application. The code consists of HTML, CSS, and JavaScript. Three of them create the magic we all experience on the internet. But there is much more than a web application that needs to work. The back-end is the other side of the applications that we don’t see, but the experience.

he web server has a crucial role in web-based applications. Since most of us leave it to the default configuration, it can leak sensitive data regarding the web server.

For now, I am assuming that you all know what is SQL or you have some experience with SQL or you are using SQL for many years. I know many people who know so much about SQL and even have created many projects based on SQL and they do not know what is SQL engine or how actually SQL database engine works. It’s obvious no one’s care about the internal working of SQL engine or something because without knowing How SQL works we can still create and access database using any SQL program.

The choice of a programming language for your startup directly depends on the needs of your project, your budget and other parameters.

Typically, when we build a single-page application, the frontend and the backend are living in two very separate worlds that are connected with a web API. Even if they are implemented with the same language (JavaScript), they cannot communicate directly using this language. They need something else in between, so we build a web API (REST, GraphQL, etc.), and that complicates everything.

If you're comfortable with working with traditional development platforms such as Heroku, but now you need to integrate into Salesforce data, there are many unexpected differences that you might discover.

RESTful APIs are everywhere, powering more of the modern world than any other API architecture. REST accounts for up to 80% of APIs according to this study by ProgrammableWeb. How those APIs are built and structured can make or break a company in today’s ultra-competitive world. Poorly-designed APIs can be difficult to use, can fail when they are needed most, and are valuable targets for hackers looking for sensitive data. On the other hand, a well-designed API that utilizes best practices makes development a breeze, attracts new customers, and creates confidence among users that can boost retention rates.

During the last couple of decades websites' functionally has increased dramatically - from simple landing pages serving simple static ads to complex progressive web apps whose functionality close to native applications including user authorization, location tracking, bluetooth handling, and offline mode.

When I was a newbie in Rails, the first couple of weeks I survived reading all the articles and understanding only like 30% of what I was doing. It was a lot of information, and one of the things that annoyed me the most was that when, after a lot of effort, I finally realized what I have to do, I have to look through all the readings and find the correct command that I need to write on my terminal (after all this time, now I can type them almost with closed eyes but at first it was incredibly tough).

The Backends-for-Frontends pattern might be exactly what you need to avoid monolithic Backend APIs and Frontends bloated with business logic.

Implementing a good GraphQL backend to serve your database data is not an easy task, you have to implement a lot of resolvers, add authorization, pagination of the fields and use a DataLoader to not repeat your database queries during relations.

I’ve spent the last 10 years of my life as a System Engineer, which means when I first had to build an API, I had no idea how to do it. I knew python quite a bit since as a SysAdmin I often had to write some smaller or bigger scripts, but building the whole API was a challenge for me. Sure — I could just google the phrase and find dozens of tutorials on how to build an API, but all of them were somehow complicated or created for raw developers (which means — with assumptions that you know already all the tools and frameworks that developers use).

In functional programming, pure functions are at the core of this paradigm. When we speak of pure functions we mean that these functions satisfy two main conditions; the first is that they will not cause any side effects and the second is that depending on their arguments they will return the same result. When you create pure functions you should try to make them take care of one thing and only one, so your functions will be very easy to test and scale. Consider the following function:

In this article, we will describe Workload identity, compare it to other approaches, and finally show a real world example on how to configure a Kubernetes cluster with Workload identity enabled.

This story is about pain, agony, and denial of ready-made solutions. It is also about changes that improve the code’s readability and help the development team stay happy. The object of this post is an interface that helps a program communicate with a database.

Explore traditional full-stack development, its limitations, and an alternative backend solution to enhance your custom-built applications.

As a back-end developer, the happy moment is to show your client that the work is now is live on the internet, everyone on the world can access the website. In this article, I will share my experience step by step to deploy your ruby on rails application on Heroku.

6 reasons why I prefer backend development to frontend development.

Track your job applications with the new Notion API. Besides that, you also use Node.js and FastifyJS to create a REST API.

While we know the many benefits of going serverless - reduced costs via pay-per-use pricing models, less operational burden/overhead, instant scalability, increased automation - the challenges are often not addressed as comprehensively. The understandable concerns over migrating can stop any architectural decisions and actions being made for fear of getting it wrong and not having the right resources. This article discusses the common concerns around going serverless and our advice to minimise their impact.

CSRF (Cross-Site Request Forgery) is an attack that impersonates a trusted user and sends a website unwanted commands. This can be done, for example, by including malicious parameters in a URL behind a link that purports to go somewhere else:

Jeremy Evans is the lead developer of the Sequel database library, the Roda web toolkit, the Rodauth authentication framework, and many other Ruby libraries. He

As BFFs can aggregate and map downstream data however you like, from various sources, each with its own architecture, testing becomes more critical.

API can break the frontend if it sends unexpected data or returns an error in the response.

In security protocols, a challenge is some data sent to the client by the server in order to generate a different response each time. Challenge-response protocols are one way to fight against replay attacks where an attacker listens to the previous messages and resends them at a later time to get the same credentials as the original message.

ver open up a Rails console to debug a problem and come away wondering how the data got so funky? Despite our best efforts the database will accept plenty of garbage data if you let it. There are tons of methods to bypass the Rails callbacks and validations while still updating your database. If you are like me you have probably used these methods in the Rails console to fix some of that funky data you found after some other code created it in the first place.

The hash function takes a variable length message input and produces a fixed-length hash output. It is commonly in the form of a 128-bit "fingerprint" or "message digest". Hashes are very useful for cryptography — they insure the integrity of transmitted data. This provides the basis for HMAC's, which provide message authentication.

IDE and File Search Key Combinations

A cipher suite is a combination of a key exchange algorithm, authentication method, bulk encryption cipher, and message authentication code.

Just in time for Halloween failures in production are scarier than most movie monsters. Here's a personal scary story of a production fail.

Technology touches almost every corner of the world economy. Even when it’s an indirect relation, in many cases tech is an essential, vital part of our societies. It just can’t fail without causing too much distress and losses. Not only financially, but especially to the human aspect.

A CORS-safelisted response header is an HTTP header which has been safelisted so that it will not be filtered when responses are processed by CORS, since they're considered safe (as the headers listed in Access-Control-Expose-Headers). By default, the safelist includes the following response headers:

A real case where abnormal ad impression patterns on a Django site nearly caused an ad network ban — and the application-level mitigation that reduced the risk.

HMAC is a protocol used for cryptographically authenticating messages. It can use any kind of cryptographic functions, and its strengh depends on the underlying function (SHA1 or MD5 for instance), and the chosen secret key. With such a combination, the HMAC verification algorithm is then known with a compound name such as HMAC-SHA1.

Recently I had the need to change certain classes -from external dependencies- loaded on a Spring Boot application. All this happened in a very restrictive environment, where I was not allowed to use other libraries or tweak the JRE, it was only possible to modify the fat JAR and environment variables or system properties.

Cross-site scripting (XSS) is a security exploit which allows an attacker to inject into a website malicious client-side code. This code is executed by the victims and lets the attackers bypass access controls and impersonate users. According to the Open Web Application Security Project, XSS was the seventh most common Web app vulnerability in 2017.

Web development includes client-side scripting, server-side scripting, server and network security setup, e-commerce development, and content management system

In cryptography, decryption is the conversion of ciphertext into cleartext.

HTTP Strict Transport Security lets a web site inform the browser that it should never load the site using HTTP and should automatically convert all attempts to access the site using HTTP to HTTPS requests instead. It consists in one HTTP header, Strict-Transport-Security, sent by the server with the resource.

So you’ve decided to choose AWS as the primary provider of your cloud service and now you’re looking into setting up your environment. You’ve got your project to be deployed and all you have left to do is choose an AWS instance that will run your machine image. But now, like many others before you, you are stumped by the countless choices of EC2 instances out there.

Cryptanalysis is the branch of cryptography that studies how to break codes and cryptosystems. Cryptanalysis creates techniques to break ciphers, in particular by methods more efficient than a brute-force search. In addition to traditional methods like frequency analysis and index of coincidence, cryptanalysis includes more recent methods, like linear cryptanalysis or differential cryptanalysis, that can break more advanced ciphers.

In cryptography, a cipher is an algorithm that can encode cleartext to make it unreadable, and to decode it back.

A Man-in-the-middle attack (MitM) intercepts a communication between two systems. For example, a Wi-Fi router can be compromised.

Here, we have four roles: Sme, Sponsor, Admin, Operations.Initially, we had only 3 roles.Operations role was added later and Operations user has permissions similar to the Admin user.In the code, we had to replace every instance of if (user.type == USER_TYPES.ADMIN) with if (user.type == USER_TYPES.ADMIN || user.type == USER_TYPES.OPERATIONS).As this is time consuming and we can also miss many instances, we have created a roles module. In the roles module,the roles are defined along with their respective permissions as seen in Code (Part-III). Based on the permissions for each role, we will evaluate the authorization for the user in each of our controller methods.If the user has access, only then he will be granted the resources.

ResponseEntity<Any> breaks type safety, complicates documentation, and hinders testing.

Datagram Transport Layer Security (DTLS) is a protocol used to secure datagram-based communications. It's based on the stream-focused Transport Layer Security (TLS), providing a similar level of security. As a datagram protocol, DTLS doesn't guarantee the order of message delivery, or even that messages will be delivered at all. However, DTLS gains the benefits of datagram protocols, too; in particular, the lower overhead and reduced latency.

Note: You should have already learned about Web Modules before reading this article.

In cryptography, a ciphertext is a scrambled message that conveys information but is not legible unless decrypted with the right cipher and the right secret (usually a key), reproducing the original cleartext. A ciphertext's security, and therefore the secrecy of the contained information, depends on using a secure cipher and keeping the key secret.

HTTP Public Key Pinning (HPKP) is a security feature that tells a web client to associate a specific cryptographic public key with a certain web server to decrease the risk of MITM attacks with forged certificates.

Creating a router allows you to take complete control when handling certain incoming requests to your site.

A CSP (Content Security Policy) is used to detect and mitigate certain types of website related attacks like XSS and data injections.

In cryptography, encryption is the conversion of cleartext into a coded text or ciphertext. A ciphertext is intended to be unreadable by unauthorized readers.

A forbidden response header name is an HTTP header name (either Set-Cookie or Set-Cookie2) that cannot be modified programmatically.

A digital certificate is a data file that binds a publicly known cryptographic key to an organization. A digital certificate contains information about an organization, such as the common name (e.g., mozilla.org), the organization unit (e.g., Mozilla Corporation), and the location (e.g., Mountain View).

Low-level languages like C, have manual memory management primitives such as malloc() and free(). In contrast, JavaScript automatically allocates memory when objects are created and frees it when they are not used anymore (garbage collection). This automaticity is a potential source of confusion: it can give developers the false impression that they don't need to worry about memory management.
