What is the best way to share a configuration value retrieved from the back end across all components of an Angular 6 application?

In the Web API's Web.config file, I have defined configurations like MAX_FILE_SIZE and others. I want to retrieve these configurations from the backend and make them available to all Angular 6 components globally. Could someone suggest the most effective way to achieve this?

It is important that these configurations are read-only in the frontend code. Additionally, these configurations might be updated at runtime on the backend from the Web.config file.

Answer №1

If you're setting up values for your Angular components internally, such as file size limits for user uploads, my response assumes you're new to Angular. In this case, your API should provide a RESTful way to retrieve configuration information. Create a service using Angular's HTTP client to fetch this data from the API, returning an Observable for easy access. Utilize ngrx to create a store that all components can access, ensuring the configuration information is readily available. Dispatch actions within the app.component to fetch and store this data, utilizing effects and reducers to update the store when necessary. This setup with ngrx ensures a centralized data source for components to react to changes effectively.
