NgRx Tips for Future-Proof Angular Apps

Are your NgRx actions making your app harder to debug? Learn how good action hygiene can future-proof your state management and simplify your Angular application.

#1about 4 minutes

Consolidate global state into a single NgRx store

Avoid splitting global state between NgRx and stateful services to improve reusability and reduce component dependencies.

#2about 2 minutes

Use selectors to compute derived state on demand

Calculate derived data using memoized selectors instead of storing it in the state to simplify reducers and reduce state size.

#3about 2 minutes

Simplify components with view model selectors

Combine multiple state slices into a single view model selector to simplify component logic and template bindings.

#4about 1 minute

Create reusable and maintainable case reducers

Handle multiple actions in a single case reducer for shared logic, but split them into separate reducers when state changes diverge.

#5about 4 minutes

Treat actions as unique events, not commands

Use the source-event pattern to name actions descriptively, avoiding sequential dispatches and improving application traceability.

#6about 2 minutes

Organize actions by grouping them by source

Structure your codebase by creating dedicated action files for each source, such as pages, APIs, or guards.

#7about 1 minute

Name NgRx effects based on their function

Name effects based on the task they perform rather than the action they listen to, improving readability and maintainability.

#8about 2 minutes

Keep effects simple by moving logic to services

Isolate complex business logic within services and call them from effects to keep the effects simple, readable, and easy to test.

#9about 1 minute

Avoid creating unnecessary boilerplate effects

Eliminate intermediate effects by having the primary effect listen to multiple source actions directly, reducing boilerplate code.

#10about 2 minutes

Apply good action hygiene within NgRx effects

Return a single unique event with a complete data payload from an effect instead of an array of command actions to decouple state updates.

#11about 3 minutes

Adopting NgRx best practices for future-proof apps

Following established best practices for NgRx store and effects improves code quality, maintainability, and performance in large Angular applications.
