Borsh: Implementation Of The Borsh Serialization Scheme

Borsh serialization for dart

A code generator for borsh serialization. To use this you need the borsh_annotation.

Installing

Use this package as a library

Depend on it

Run this command:

With Dart:

 $ dart pub add borsh

With Flutter:

 $ flutter pub add borsh

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:
  borsh: ^0.3.1

Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:borsh/borsh.dart';

Versioning Serializers

In a distributed system, microservices exchange information between one another, using predefined communication protocols. Some disruptions in data serialization might occur when software developers alter different microservices independently. In this article, I will revisit the most relevant practices for versioning serializers and spreading their changes throughout a system.

Communication Protocols

The OSI model establishes 7 abstraction layers for communication over the Internet. Microservices usually exchange information using the last, seventh layer, called the application layer, leveraging either preexisting protocols like HTTP or custom-made ones. I find it significant to note that the HTTP/2 protocol relies on the TCP protocol (the transport layer) which in turn relies on the IP protocol (the Internet layer) — this means that sharing information between two machines involves more work than meets the eye. I will not describe the fundamental differences between text and binary protocols here, but I want to stress that HTTP belongs to the family of the former, compared to both the TCP and the IP protocols, which belong to the family of the latter.

From this moment on I shall discuss serialization within the bounds of the HTTP protocol, mostly because of its popularity and applicability in distributed systems. Using the aforementioned protocol, a developer can transfer an information of a reasonable size in:

  • the request line (including the query parameters),
  • the headers of a request or a response (the protocol allows for custom ones),
  • the message body of a the request or a response.

Java Serialization Interview Questions & Answers [For Beginners & Experienced]

Java is one of the better programming languages out there in the world. We have been fortunate enough to see Java develop over time and become the massively popular language we know it as today. These improvements, which were made in Java, led to the inclusion of some really crucial features that define how we write programs today. One of those features is Serialization.

In its essence, serialization is just a mechanism used to store an object into the memory. So, when we say we are serializing an object, we mean that we are converting the object in question from the state, which it was into a stream of bytes. This conversion from its native state to the byte stream makes writing this object to a file a breeze.

This file can then be transported anywhere we wish, and to access the object and its features, all we need to do is de-serialize the object. De-serialization, as the name suggests, is the opposite of serialization. Here, we convert the byte’s stream into the native state of the object to use the object.

Serialization enables developers to write their code with a certain level of flexibility. The ability to take the object and use it with its native property elsewhere is crucial in today’s workflow. No wonder recruiters want their potential employees to know more about object serialization in java.

Whether you have used serialization in your projects or not, you cannot merely let the importance of it slide. So, to aid you in your endeavor of becoming a professional java developer, we have collected some fascinating java serialization interview questions, which you will find below.

What Exactly Does the Serializer Do?

After dabbling in Ruby on Rails and venturing into JavaScript, I found it very useful to have Rails as the backend API. It is setup in such a way where it can easily render JSON data to be used on the JavaScript side and therefore the browser.

Building my app was going well until it came time to render attributes of a model in relation to another model.

In Ruby, the relationships are set up like so and through naming conventions it knows where to look for whatever it’s looking for. Here, I have 3 models in a many-to-many relationship.

class Review < ApplicationRecord

  belongs_to :user
  belongs_to :wine
end
class User < ApplicationRecord
  has_many :reviews
  has_many :wines, through: :reviews
end
class Wine < ApplicationRecord
  has_many :reviews, :dependent => :destroy
  has_many :users, through: :reviews
end

In a Rails app, to create the frontend I would just need to create html.erb files within a folder (within app/views folder) that correlates with the above models by sharing the same name (naming convention). Then, in the controller actions I would just need to specify what to render. Through naming convention of the files, Rails automatically (almost magically) knows what is linked to what and therefore what to render.

But, I’m venturing into using JavaScript/HTML as my frontend, remember?

So, in the controller actions I need to tell the app what to render (via ‘render json:’ then whatever specified to render).

Serialization in Java: Everything You Need To Know [2021]

With the ever-increasing boom of the IT industry, our reliance on it seems to be growing with every passing day. This steady growth has pushed many working professionals to take up programming languages in a bid to stay relevant within the industry. While the industry makes use of several languages to service its clients, a few languages are more frequently used than others. Java is one such language.

Irrespective of whether you’re a fresher or a veteran, a sound knowledge of Java will stand to benefit you at every turn of your software journey. Like any other programming language, Java also packs a comprehensive syllabus of its own. One has to practice the language daily to get a hold of all the various concepts that punctuate the language. One such concept that helps users a lot is the practice of serialization in Java.

Introduction

Serialization in the context of Java refers to the process in which a Java code object is systematically converted into a Byte Stream. This is done to enable the efficient transfer of the said object code from one Java virtual machine to another. Subsequently, this allows for its recreation with the help of deserialization. We use serialization to meet multiple objectives. Let’s have a look at the most popular and relevant ones in the section below.
