The functional level is not very big, but there is a structural defect that is obvious, that is, the project structure is excessively coupled, and the coupling of the project ( […]

In total, there are only about 50 keywords that need to be remembered. Throughout the programming universe, no one can surpass them. Some of these reserved keywords are “icing on the cake”, what is

Now we can write specific business code in the logic layer. Like most online platforms, the blog platform operates based on the user account system, so we need to Complete the CURD operation of the user

By analogy, we can imagine telling the first graders of primary school Wang Bo’s famous essay “Preface to the Pavilion of King Teng”. How likely are the primary school students to

However, if you want to communicate data among multiple coroutine tasks, you need the participation of channels. We can encapsulate the data as An object, and then pass the

Goroutine is the core essence of the Go language design system. It is very lightweight. A Goroutine only occupies a few KB, and these few KB are enough for the Goroutine to run, which can support

Then we can configure the template of the project. Here we use the template engine built in Iris. In fact, using a template engine does not mean that End coupling, the

The owner of the car released a video saying that the car had just driven out of the garage without exposure to the sun or any collision. Spontaneous combustion, see also spontaneous

To put it bluntly, it is to operate the row objects or table objects of the database through a schematized grammar. Compared with the relatively flexible and complex SQL statements, ORM is easy to use.

Now let’s take a look at the basic functions of Iris, how to write the project entry file and configure the routing system. Project Entry In fact,

At the programming language level, there are generally two schools of error handling methods, namely the exception capture mechanism represented by Python (try….catch); and

The name of the rainbow goddess is resounding all over the world, and the name moves all corners of the world. No one can match the fast word alone. Even Gin, who is known for

As we all know, the whole program is executed from top to bottom, but sometimes, it is not just as simple as executing from top to bottom. Generally speaking, there
