Angular Material Progress Bar
The <mat-progress-bar> is a horizontal progress-bar used for indicating the progress and activity.
Progress Bar Modes
It supports four modes: determinate, indeterminate, buffer, and query.
Determinate operations are those where the percentage of the operation is complete.
It is the default mode, and the value property represents the progress.
In an Indeterminate operation, the user is asked to wait until the previous one finishes, and it is not necessary to indicate how much time it will use the indefinite pointer.
In this mode, the value property is ignored.
Use the buffer mode of the progress-bar to indicate the activity or loading of the server.
In the "buffer" mode, the value determines the primary bar's progress, while the buffer is used to show the buffering progress.
Use the query-mode of the progress-bar to indicate pre-loading before the actual loading begins.
In "Query" mode, the progress-bar inversion presents as an indefinite bar. After the response progress is available, the mode must be determined to express the progress. In this mode, the value property is ignored.
Using the color property, the color of the progress bar will change. By default, progress-bars use the theme's primary color. It can be changed to accent or warn.
Each progress bar should be given a meaningful label by area-label or area-labeledby.
<Mat-progress-spinner> and <mat-spinner> are a circular indicator of activity or progress. The md-progress-circular and md-progress-linear are the progress directives, and they show loading content messages in the application.
The following table shows the parameters and description of many attributes of md-progress-circular.
The example shows the use of the md-progress-circular directive and the uses of circular progress bars.
The following example shows the use of linear progress bars.
