Overview of this book

Python is a flexible language that can be used for much more than just script development. By knowing the Python RESTful APIs work, you can build a powerful backend for web applications and mobile applications using Python. You'll take your first steps by building a simple API and learning how the frontend web interface can communicate with the backend. You'll also learn how to serialize and deserialize objects using the marshmallow library. Then, you'll learn how to authenticate and authorize users using Flask-JWT. You'll also learn how to enhance your APIs by adding useful features, such as email, image upload, searching, and pagination. You'll wrap up the whole book by deploying your APIs to the cloud. By the end of this book, you'll have the confidence and skill to leverage the power of RESTful APIs and Python to build efficient web applications.

The size of the image will affect the speed of the website. Imagine looking at a picture that's 10 MB in size. If there are 10 pictures on one page, this website will be 100 MB in size, and so it will take a lot of time to get a page. Due to this, a good practice to reduce the size of the image and compress it so that it's around 500 KB in size instead.

In addition, we will also convert the image into JPEG (it has the .JPG file extension). JPEG is an image compression technology that can remove unnoticeable, insignificant details in an image, thus achieving a smaller file size. Besides, it is often regarded as acceptable to have a lower image quality for web use.

In our Smilecook application, we will convert all our uploaded images into JPG format and compress them. We will do this through the Pillow package.

Note

We cannot have a transparent image in JPEG format. If we save an image with the background removed as a JPEG, the background...
