Default configuration

Configuration in dattiktok.com Core is performed using one or more configuration providers. Configuration providers read configuration data from key-value pairs using a variety of configuration sources: Settings files, such as dattiktok.com; Environment variables; Azure Key Vault; Azure App Configuration; Command-line arguments.

ConfigurationFileMap fileMap = new ConfigurationFileMap(strConfigPath); Configuration configuration = dattiktok.comppedMachineConfiguration(fileMap); MailSettingsSectionGroup thisMail = dattiktok.comtionGroup("dattiktok.com") as MailSettingsSectionGroup; .

It teaches you about various sources, providers and how to read config data. It also shows you how to make your config data type safe. Why do we need configuration? Well, the answer is that we need our app to perform differently without necessarily recompile it. The reason for that is to make it flexible for different environments. It should be enough to just change a config value to get the app to go towards a completely new endpoint for example.

NET has our back, it knows config data can come from a million different places, files, like JSON or ini, environment variables or even Azure. NET has a set of services, so called providers that reads out this config data for us.

What we need to know to work efficiently with it, is to know what providers exist so we know where we can place our config data and in what order the data is read, so we know what data will take effect. Also, it's helpful to know that all data are key-value pairs. It doesn't stop the data from being nested though. Don't worry there are two different ways we can deal with nesting, untyped and typed. Config data can come from many sources.

Here's a list of all the different sources:. Config data is read in a certain order. Host configuration is the first thing to be read followed by JSON data found in appsettings. The complete read order looks like so:. In the default configuration case, adds the host configuration and setting it as the first source for the app configuration. App setttings JSON file. There's an appsettings. Environment specific app settings JSON.

After the initial appsettings. So essentially it's looking for a file on this format appsettings. For example, appsettings. App secrets. If you are running in a dev environment it tries to read secrets next. Environment variables. After that it reads any environment variables using the Environment Variables configuration provider.

Command-line arguments. Lastly it reads command line arguments using the Command-line configuration provider. NOTE, if the same key exist in two different sources it's the latter one that gets applied. For example i a key exist in appsetttings. I've left some hopefully useful links so you can learn more about all the different providers and options.

Hopefully this article gives you a good foundation to continue learning. Builder settings. Configuration management docs for ASP. To read configuration data lets turn our attention to Program.

Here we are injecting an instance of IConfiguration. It will attempt to read data from appsettings. Looking at the content of appsettings. To read a non-nested value like AllowedHosts we can type like so:. We instead type like so:. NOTE, you are likely to want to access this kind of data when setting up services so you are more likely to read from Configuration instance in ConfigureServices method rather than the constructor, as is demonstrated above.

With that said, all you need to do is to inject IConfiguration in any constructor where you might need it, like a controller for example, like so:. We stated earlier that the last provider to be read is the one that decided the value on the config data.

Lets demo this by placing a setting API like so in appsetting. Change the code in the Startup constructor to read API , like so:. As you can see, the last read source, appsettings. At some point, you might loose track of what configuration you have. You might have different keys, or more, at various levels of nesting. The problem with that is that it's starting to get messy. Knowing what keys are actually used could be a combination of looking into JSON files, environment variables or even the source code.

So how do you approach and manage such a mess? The way to manage it is how you manage most things in. NET and C , type it. The idea is to have variables or structures like classes for most things you plan to use, your config data shouldn't be any different. So how do we type our config data then - use a class.

Let's assume you have a few endpoints ProductsServiceUrl and CartServiceUrl that you want to keep track of and that they should be set to different values in different environment. You can create a class for that, like so:. The next thing we want to do is to tell ASP. NET to bind an instance of the above class to a specific section of our config.

Imagine you now have a section in appsettings. Once you've created a class for this and added the config data it's time to read out the data. We can read the data like by locating the constructor of Startup class in Startup. The use of GetSection enables us to drill down into the part of the config that's interesting for us. Using bind we bind the sections content to an instance of ServiceConfiguration and thereby populate the instance with the values from the config section. You learned how config data can exist in various sources.

You also learned how ASP. NET was able to read from these sources. Furthermore, you were shown various ways to read nested and un nested data.

Lastly you looked at how to make your config data more type safe. You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
