Hello, week-9. I want to post a blog to quickly review the API topic to learn more about REST calls. I got confused; I researched about it. It has the Understanding And Using REST APIs.

What is a REST API

API (Application Programming Interface) – A set of rules allows programs to support any other. The developer creates the API on the server and enables the client to speak to it. 

The REST (Representational State Transfer) determines how the API. It is a set of rules that developers follow when they create their API. One of the rules states that one should get data (called a resource) when linking to a specific URL. Each URL made a request, while the data sent back to is called a response.

The Anatomy Of A Request #

It’s important to know that a request with four points:

• The endpoint
• The method
• The headers
• The data (or body)
  

The endpoint – URL that requests for (root-endpoint/?). The root-endpoint is the starting point of the API that is ordering.

The path determines the resource request. For example, it is like an automatic answering machine. That asks to press 1 for service, press 2 for another service, 3 for yet another service, and so on.

The Method

The method is the type of request sent to the server:

• GET – Request to get a resource from a server. It will perform a `GET` request; the server looks for the requested data and sends it back.
• POST – Request to create a new resource on a server. It performs a `POST` request, the server creates a new entry in the database and tells whether the creation is successful.
• PUT & PATCH – Requests to update a resource on a server. If performing a `PUT` or `PATCH` request, the server updates an entry in the database and tells whether the update is successful.
• DELETE – Request to delete a resource from a server. If performing a `DELETE` request, the server deletes an entry in the database and tells whether the deletion is successful.

These methods provide meaning for the request made. Perform steps: Create, Read, Update and Delete (CRUD).

The HEAD: it used to provide information to both the client and server. It has many purposes, such as authentication and giving information about the body content. It can find a list of valid headers on MDN’s HTTP Headers Reference.

The Data – contains information sent to the server. It only used POST, PUT, PATCH, or DELETE requests.

One of the more interesting topics that we covered in class was semantic versioning. I found it interesting because it is something that I see all the time but had no idea what it meant. After reading over the documentation, I’ve learned that semantic versioning is a set of rules that dictate how version numbers are assigned and incremented. Semantic versioning was proposed as a solution to dependency hell, which occurs when you version lock or when version promiscuity prevents you from easily and safely moving your project forward.

Semantic versioning works in three parts, X, Y, and Z. They are usually written as X.Y.Z, as that is the form semantic versioning must take. Each component says a different thing about the version. The X states what the current major release is, the Y states what the current minor release is after the last major release, and the Z states what the current patch release is after the last minor release. What do a major release, minor release, and patch release mean?

A major release is the first part of the semantic versioning framework. It goes at beginning of the version number. A major release occurs when you make incompatible API changes. The changes must be backward incompatible in order to be considered major. A major version zero is for initial development, and anything may change at any time. When a new major update is released, the minor, and patch version numbers must be reset back to zero.

A minor release is the second part of the semantic versioning framework. It goes in the middle of version number.  A minor release occurs when you add functionality in a backward compatible manner. A minor release needs to be incremented every time any public API functionality is marked as deprecated. Minor releases could also be incremented if substantial new functionality or improvements are introduced within the private code, and it could include patch level changes. When a minor update is released, the patch version number must be reset to zero.

A patch release is the third and final part of the semantic versioning framework. It goes at the end of the version number, and it refers to an update that focuses either exclusively or primarily on bug fixes. A bug fix is a change made to the code to correct incorrect behavior. A patch release does not add any new features, it just modifies existing code to fix errors or make the code run the way it was intended. All the bug fixes must be backward compatible.

This week I read a blog post about eight ways to make software development go by faster, and I thought it was an interesting read to share with everyone. The blog starts off describing time as the most valuable resource in the software world, and how faster is better. The blog then goes into the different options of speed such as marathons, extreme sprints, moderate sprints, and intervals. You can select between the four for whichever project you are doing. The eight ways are shown as skills, experience, system complexity, technical debt, refactoring, slow automatic tests, overtime/deadlines, and passion. It concludes by describing software development speed as complex, and that it has no easy solution, but it does have a lot of different solutions depending on how you work. I selected this blog post because this class is a software development focused class, and I see my future in that area, so I want to know the most about it.I think this blog was a great read that I recommend for many reasons. A huge reason I selected this blog is because I want to become a software developer myself in the future, so it was a read that I could enjoy. It is good to read the blogs on things you care about because it makes the recommendation much more credible. Another reason I selected this blog was because it does a good job of showing the most important part of a software developer job. How to make more out of less time. It gives a huge number of different ways to solve the problem, and they all are viable answers. The last reason I will be going over is that it does a good job of tempering expectations. Time management is an important resource when it comes to software development, but it is not just some beginner’s problem. Experts still struggle with it occasionally today, so do not expect it to be an easy problem to answer. I learned about how important speed is to software development, and how many factors contribute to it, and how complex it is.This material affected me hugely because it showed how important conserving speed to save money is, and how I can use certain methods in the future to make projects go faster. I will take all of this knowledge with me as I continue in my career. Everyone who wants a career in software development needs to read this because it shows how time literally is money.

A while ago, I introduced the concept of API in the information technology industry. In addition, there are 3 different types of Web Services APIs which are REST APIs, SOAP APIs, and RPC APIs. Among them, REST APIs is no doubt the most popular API currently. REST APIs, also known as RESTful APIs, stands for Representational State Transfer. It is based on four different HTTP commands which are GET, PUT, POST, and DELETE.

When a client request is made via a RESTful API, it transfers a representation of the state of the resource to the endpoint. Then the information is delivered in one of several formats via HTTP: JSON (Javascript Object Notation), HTML, XLT, Python, PHP, or plain text. JSON is the most generally popular due to its readability.

According to the RESTful API website, a service interface needs to apply these 6 guiding principles and constraints to be referred to as RESTful:

1. Uniform Interface

Multiple architectural constraints applying to the interface so that information is transferred in a standard form requiring:

Identification resources – resources requested are identifiable and unique from the representations sent to the client

Manipulation of resources through representations – clients can manipulate the resources via the representation

Self-descriptive messages – each resource representation should carry enough information that the client can manipulate.

Hypermedia as the engine of application state – after accessing a resource, the client should be able to use hyperlinks to find all other currently available actions.

2. Client – server

It is the architecture made up of clients, servers, and resources, with requests managed through HTTP.

3. Stateless

Statelessness means that no client information is stored between each request and that the server cannot take advantage of previously stored context information.

4. Cacheable

There are cacheable and non-cacheable responses. If the response is cacheable, the client can reuse the response data for later use.

5. Layered system

A layered system allows an architecture to be composed of hierarchical layers by constraining component behavior.

6. Code on demand (optional)

It is the ability to send executable code from the server to the client when requested, extending client functionality.

Although REST API has these criteria to conform to, it is still considered easier to use than SOAP (Simple Object Access Protocol). The reason is that while REST is a set of guidelines which is simple to implement and faster in response time, SOAP has specific requirements like XML messaging, and built-in security and transaction compliance that make it slower and heavier.

Overall, the point of this blog is to introduce you to REST API, REST is just a term indicating the constraints applying to the API. In order to understand the power of REST, I would suggest going to create one and see how simple and convenient it is.

Hello, week-9. I want to post a blog to quickly review the API topic to learn more about REST calls. I got confused; I researched about it. It has the Understanding And Using REST APIs.

What is a REST API

API (Application Programming Interface) – A set of rules allows programs to support any other. The developer creates the API on the server and enables the client to speak to it. 

The REST (Representational State Transfer) determines how the API. It is a set of rules that developers follow when they create their API. One of the rules states that one should get data (called a resource) when linking to a specific URL. Each URL made a request, while the data sent back to is called a response.

The Anatomy Of A Request #

It’s important to know that a request with four points:

• The endpoint
• The method
• The headers
• The data (or body)
  

The endpoint – URL that requests for (root-endpoint/?). The root-endpoint is the starting point of the API that is ordering.

The path determines the resource request. For example, it is like an automatic answering machine. That asks to press 1 for service, press 2 for another service, 3 for yet another service, and so on.

The Method

The method is the type of request sent to the server:

• GET – Request to get a resource from a server. It will perform a `GET` request; the server looks for the requested data and sends it back.
• POST – Request to create a new resource on a server. It performs a `POST` request, the server creates a new entry in the database and tells whether the creation is successful.
• PUT & PATCH – Requests to update a resource on a server. If performing a `PUT` or `PATCH` request, the server updates an entry in the database and tells whether the update is successful.
• DELETE – Request to delete a resource from a server. If performing a `DELETE` request, the server deletes an entry in the database and tells whether the deletion is successful.

These methods provide meaning for the request made. Perform steps: Create, Read, Update and Delete (CRUD).

The HEAD: it used to provide information to both the client and server. It has many purposes, such as authentication and giving information about the body content. It can find a list of valid headers on MDN’s HTTP Headers Reference.

The Data – contains information sent to the server. It only used POST, PUT, PATCH, or DELETE requests.
