Reactive Extension for JavaScript (RxJS) Corporate Training

Coordinate Asynchronous JavaScript With Tested RxJS Streams and Clean Subscription Lifecycles

Edstellar develops reactive programming skills through realistic asynchronous features. Participants compose observable pipelines, share streams, and manage cancellation before testing timing and error behavior. A complete reactive feature is reviewed for understandable operator choices, correct emissions, and lifecycle handling that avoids lingering subscriptions or unintended concurrent work.

1. Step 01

   Consult

   We assess ES6+, promises, and asynchronous programming experience to identify gaps in observable thinking, operator selection, shared subscriptions, or managing cancellation and errors.

2. Step 02

   Plan

   We establish observables and lifecycle management before operators and multicasting, then build application patterns, test stream behavior, and assemble the reactive feature.

3. Step 03

   Align

   We align reactive JavaScript expertise with the cohort's frontend context, choosing familiar asynchronous examples while providing foundational support for developers new to RxJS.

4. Step 04

   Customize

   We adapt sample typeahead and polling workflows to relevant applications, introducing timing, recovery, and cancellation cases that require deliberate stream coordination.

5. Step 05

   Execute

   Participants compose operator chains, share streams, and write marble tests, receiving feedback on emission timing, subscription leaks, backoff behavior, and the clarity of cancellation logic.

6. Step 06

   Evaluate

   We assess the reactive feature for correct tested emissions, purposeful operator composition, reliable error recovery, and clean subscription behavior across normal and interrupted interactions.
