, also known as preloaders or spinners, are used to indicate that a website or application is loading content. They are often used to inform the user that the page is still loading, while providing visual feedback.

There are many different types of CSS loaders, including spinners, progress bars, and loading animations. Spinners are the most common type of loader, and they typically consist of a simple animation that spins around to indicate that something is loading. Progress bars, on the other hand, are used to show the progress of a loading operation, such as the percentage of a page that has been loaded.

CSS loaders can be created using a variety of techniques, including CSS animations, SVG, and JavaScript. CSS animations are the most commonly used technique for creating CSS loaders, as they are easy to implement and require minimal code. SVG, on the other hand, is more complex but allows for more detailed and customizable animations. JavaScript can also be used to create CSS loaders, but it is typically only used for more advanced animations or interactive loaders.

When creating a CSS loader, it is important to keep in mind that loaders should be small and lightweight, so that they do not slow down the loading process. Additionally, they should be designed to be visually appealing, so that they do not detract from the overall look and feel of the website or application.

In conclusion, CSS loaders are an important aspect of web design and development, as they provide visual feedback to users while a website or application is loading. They can be created using a variety of techniques, including CSS animations, SVG, and JavaScript, and should be designed to be small, lightweight, and visually appealing.

Another thing to keep in mind when creating CSS loaders is accessibility. It is important to ensure that the loader is accessible to users with disabilities, such as screen readers. This can be achieved by providing alternative text for the loader, and using semantic HTML elements to structure the loader. Additionally, it's important to give the user an option to stop the loader, in case they want to move on to a different page or task before the loading is finished.

Another important aspect of CSS loaders is performance. As mentioned earlier, loaders should be small and lightweight, so that they don't slow down the loading process. To achieve this, keep the number of elements used to create the loader to a minimum, and use CSS transitions and animations instead of JavaScript for simple animations. Additionally, you can use CSS sprites to reduce the number of HTTP requests required to load the loader.

CSS loaders can also be used to improve the overall user experience of a website or application. For example, a loader can be used to load and display content as it becomes available, rather than loading all of the content at once. This can improve the perceived performance of the website or application, as the user is able to see and interact with some of the content while the rest of the page is still loading.

In summary, CSS loaders are an important aspect of web design and development that can improve the overall user experience. They should be designed to be small, lightweight, visually appealing and accessible, and performance should be taken into consideration while creating them. Additionally, they can be used to improve the overall user experience of a website or application by loading and displaying content as it becomes available.

Practical suggestions for creating REST APIs

Have you ever been annoyed by a poor API where everything is a guessing game? I have, in fact.

Your backend API must be designed consistently in the age of microservices.

We'll discuss some top recommendations today. So please buckle up as we'll make it short and sweet.

Any API design follows something called Resource Oriented Design It consists of three key concepts

 A resource is a piece of data, For example, 

 A group of resources is called a collection. Example: 

 Identifies the location of resource or collection. Example: /user

For example, if you want to get the list of orders.

For example, if you want to get products from a particular shop.

/system-orders/{order_id} or /system-orders/{OrderId}

If you want to get all the users of a system.

4. URL Starts With a Collection and Ends With an Identifier

If want to keep the concept singular and consistent.

GET /shops/:shopId/category/:categoryId/price

This is bad because it’s pointing to a property instead of a resource.

GET /shops/:shopId/ or GET /category/:categoryId

Don’t use verbs to express your intention in the URL. Instead, use proper HTTP methods to describe the operation.

POST /updateuser/{userId} or GET /getusers

You have an endpoint that returns nothing but an operation. In this case, you can use verbs. For example, if you want to resend the alert to a user.

Keep in mind that these are not our CRUD operations. Rather, these are considered functions that do a specific job in our system.

If you’re building a system in which the request body or response is JSON, the property names should be in camelCase

{ user_name: "Mohammad Faisal" user_id: "1" }

{ userName: "Mohammad Faisal" userId: "1" }

RESTful HTTP services MUST implement the /health and /version and /metrics API endpoints. They will provide the following info.

/health Respond to requests to /health with a 200 OK status code.

/version Respond to request to /version with the version number.

/metrics This endpoint will provide various metrics like average response time.

/debug and /status endpoints are also highly recommended.

9. Don’t Use table_name for the Resource Name

Don’t just use the table name as your resource name. In the long run, this kind of laziness can be harmful.

This is because exposing the underlying architecture is not your purpose.

There are many good API design tools for good documentation, such as:

Having good and detailed documentation results in a great user experience for your API consumers.

Always use versioning for the API and move it all the way to the left so that it has the highest scope. The version number should be v1, v2 etc.

http://api.domain.com/v1/shops/3/products

Always use versioning in your API because if the API is being used by external entities, changing the endpoint can break their functionality.

12. Include Total Number of Resources in Your Response

If an API returns a list of objects always include the total number of resources in the response. You can use the total property for this.

Always accept limit and offset parameters in GET operations.

This is because it’s necessary for pagination on the front end.

The amount of data being returned should also be taken into consideration. Add a fields parameter to expose only the required fields from your API.

Example: Only return the name, address, and contact of the shops.

GET /shops?fields=id,name,address,contact

It also helps to reduce the response size in some cases.

15. Don’t Pass Authentication Tokens in URL

This is a very bad practice because often URLs are logged and the authentication token will also be logged unnecessarily.

GET /shops/123?token=some_kind_of_authenticaiton_token

Authorization: Bearer xxxxxx, Extra yyyyy

Also, authorization tokens should be short-lived

The server should not assume the content type. For example, if you accept application/x-www-form-urlencoded then an attacker can create a form and trigger a simple POST request.

So, always validate the content-type and if you want to go with a default one use content-type: application/json

HTTP methods serve the purpose of explaining CRUD functionality.

GET: To retrieve a representation of a resource.

POST: To create new resources and sub-resources.
