𝐇𝐨𝐰 𝐭𝐨 𝐢𝐧𝐜𝐫𝐞𝐚𝐬𝐞 𝐭𝐡𝐞 𝐫𝐞𝐚𝐝𝐚𝐛𝐢𝐥𝐢𝐭𝐲 𝐨𝐟 𝐲𝐨𝐮𝐫 𝐜𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧 𝐜𝐨𝐝𝐞?

I'm sure everyone reading this post has heard of 𝐞𝐱𝐭𝐞𝐧𝐬𝐢𝐨𝐧 𝐦𝐞𝐭𝐡𝐨𝐝𝐬. 🧵

Good practice at the end of the post. 👌

#Dotnet

When creating an application, the first thing we do is configure it.

We configure: logging, connect the database with ORM, and configure CORS.
We define the method of authentication, DI services, and various bindings.

When we write all this code in the 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐞𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 𝐦𝐞𝐭𝐡𝐨𝐝 𝐢𝐧 𝐏𝐫𝐨𝐠𝐫𝐚𝐦.𝐜𝐬, everything gets messy. These methods can reach over 500 lines of configuration code.
Changing something is very difficult to navigate.

𝐓𝐨 𝐬𝐞𝐩𝐚𝐫𝐚𝐭𝐞 𝐭𝐡𝐞 𝐜𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐞𝐫𝐯𝐢𝐜𝐞, 𝐰𝐞 𝐜𝐚𝐧 𝐝𝐨 𝐭𝐡𝐞 𝐟𝐨𝐥𝐥𝐨𝐰𝐢𝐧𝐠:

• We will create a folder called "𝐄𝐱𝐭𝐞𝐧𝐬𝐢𝐨𝐧𝐬" in our web project.

• Let's say we're moving the Hangfire settings first, we need to create the 𝐀𝐝𝐝𝐇𝐚𝐧𝐠𝐟𝐢𝐫𝐞.𝐜𝐬 𝐜𝐥𝐚𝐬𝐬
• Inside the class, we will add only one 𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐞𝐇𝐚𝐧𝐠𝐟𝐢𝐫𝐞 method that will be called at the point of configuring Hangfire.

The method is static, without a return value.
As a parameter, it has "𝐭𝐡𝐢𝐬", which is the data type of the object that is using the given extension, in this case, 𝐈𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐂𝐨𝐥𝐥𝐞𝐜𝐭𝐢𝐨𝐧.

Within the method, we will configure settings over the services collection, as we would in the Program class.

As a result, we get a method that we can use in the Program class:

𝐛𝐮𝐢𝐥𝐝𝐞𝐫.𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬.𝐂𝐨𝐧𝐟𝐢𝐠𝐮𝐫𝐞𝐂𝐨𝐫𝐬();

When we repeat this for each configuration, we get separate configurations, modules responsible for only one thing, and significantly more readable code.

𝐆𝐨𝐨𝐝 𝐩𝐫𝐚𝐜𝐭𝐢𝐜𝐞:

Each project configures its settings on its level, and the Program class calls the configurations of each project in the solution.
