Recently I'm developing an Angular application, but with the increasing complexity and pressing releases, the need to perform rapid deploys is huge.
Here some problems:
- deploy functionalities but some of them are not completely finished
- test a feature only for certain number of users
But how can I solve this pain?
Azure App Configuration
I could create a service that exposes the configurations, but the maintenance and development costs of this service would perhaps become too high for what I need.
To minimise costs I decided to rely on Azure because we can use its App Configuration service.
We are going to explore the Feature manager section.
First thing first, you need to have an Azure account, free plan works good for this example,
then you have to create the App Configuration resource.
You need to specify:
- Resource group
- Resource name
You can set Pricing tier => Free
Feature flag creation
In the Feature Manager you can define your feature flags
👉 You can use Create to create a new feature flag
You can also define different types of filter
Connection String is needed to retrieve the configuration from your client
That's all from the Azure Side
To connect Angular with Azure App Configuration you need to add two packages into your Angular app.
You can install them with npm.
Then in your Angular component you can read and use the configuration like this:
This env variable -> AZURE_APP_CONFIG_CONNECTION_STRING contains the Azure connection string.
In the key property you need to pass the feature flag unique key.
That's all folks 🚀
🎉 As you can see it's super easy to implement this functionality and I'm so happy about it. 😄

You can convert it to a directive, something like
I love the Feature Flag and I use this Azure service in a lot of my products.
