Functional groupings of RxJS operators.

Functional Groupings of RxJS Operators

As we discussed in our previous article on Getting Started with RxJS the RxLibrary provides a long list of Operators to solve a variety of our use cases.

Each one of these operators provide declarative syntax to address unique requirements in your application development. These operators can help us avoid lot of custom implementations and save us lot of development and maintenance time.

We can implement complex business use cases just by using different combinations of these operators with minimal effort. These decalarative operators also make our code clean, roboust and less error prone.

From the functionality point of view, we may divided these operators broadly into the following main categories and we will look into them in more detail on their respective demo or group pages later on.

Create Operators

Join Operators

Data Handling Operators

Create Operators...

Create operators help us create the data streams from specifc local or remote sources like:

Local array of values or comma separated values
Remote http or web socket end points
Data from perioic intervals etc.

Join Operators...

Join operators enables us to merge the data from multiple streams in various ways. For example:

Merging the data items from the given streams in order
Merging the data items without any order constraint
Merging the data items into arrays
Merging the data items from the given sources by index etc.

Filter Data Operators...

Filter operators filters the incoming data in multiple desired ways like:

Filter by index numbers
Filter using time intervals
Filter using logical conditions etc.

Transform Data Operators...

Transform, Accumulation and Recursive operators enable us modify the incoming data using various functions or other dependant data streams.

Group Data Operators...

This functional group includes grouping and buffering operations.

Handle Error Operators...

As the operator names suggest these are the common error handling operations and we will look into their usage in their respective demo pages.

Utility Operators...

These utility operators provide miscellaneous but very useful features for our data handling activities.
