While looking at the file. That said, we can extract it in a separate variable and access it through interpolation:. After the successful refactoring of the FileService, we will create a component that consumes the service and downloads our file. We will name it, respectfully, DownloadComponent, to match the one for upload that we already have. Angular CLI steps in once more with its command for a component generation:. This time we can skip the creation of the folder because the CLI will do that for us.
The behavior of the DownloadComponent will follow the general pattern — it will call the FileService, handle the response, and propagate it back to its parent component.
To accomplish that, we have to add logic to the download. With this, we can wrap up the implementation of the download operation. To choose a file to download, we first need to list those files somewhere in the application and trigger the download request with the help of the UI components. As mentioned in the beginning, we will load a list of users from the database and take their corresponding profile pictures.
But to have something to show, we first need to create some users. On the homepage of the application, by entering credentials and uploading a picture, we can successfully create a User.
When we add a user, the profile picture will also automatically appear in a folder inside our application. For the sake of simplicity, we will show them below the user creation form.
Each photo in the list will have an associated download button which will trigger the download for that particular file. For the realization of the idea of iterating through a list of users, we first need to load the users from the database.
Luckily, we already have a method in the app. Here, we also added the selector for the DownloadComponent so its template renders next to each profile picture. By clicking the download button, we will get a message that we have hit the download end-point:. With this implementation, we are manipulating the user data that we read from the database, selecting image properties, and showing them.
But what if we want to read the files directly from a folder? To be able to read from a folder, we need its path. When we access the desired folder, we pick up the files with specific extensions since we only want pictures. That way we will get paths for each file and render them on the UI as we do now by reading from the database.
Firstly, we are going to add a new end-point to our FileController. We will fill it with the necessary logic for reading. Note: If the only photos in the folder are the ones associated with users, try to add more files so that there is a clear difference between these two approaches. The updated FileController.
