5 Advanced React Patterns

View Original View Raw

Summary

This article provides an overview of 5 advanced React patterns that are commonly used within the React community, including compound components, control props, custom hooks, props getters, and state reducer patterns. It provides examples of code and lists pros and cons for each pattern, as well as criteria for comparison. It also provides a diagram to help developers choose the right pattern for the right need. Furthermore, it mentions public libraries using each pattern and credits Kent C. Dodds for his influential work in the React community.

Q&As

What patterns have been developed for React developers building components for other developers?
The 5 patterns developed for React developers building components for other developers are Compound Components Pattern, Control Props Pattern, Custom Hook Pattern, Props Getters Pattern, and State Reducer Pattern.

What are the pros and cons of the Compound Components Pattern?
The pros of the Compound Components Pattern are reduced API complexity, flexible markup structure, and separation of concerns. The cons are too much UI flexibility and heavier JSX.

What criteria should be taken into consideration when selecting an advanced React pattern?
The criteria to be taken into consideration when selecting an advanced React pattern are inversion of control and implementation complexity.

What are the advantages of using the Props Getters Pattern?
The advantages of using the Props Getters Pattern are ease of use and flexibility.

What is the State Reducer Pattern and which public libraries use it?
The State Reducer Pattern is a pattern that gives an advanced way for developers to change how a component operates internally. Public libraries that use it are Downshift and React Table.

Technical terms

React: A JavaScript library for building user interfaces.
Prop Drilling: The process of passing props from a parent component to a child component.
Controlled Component: A component whose behavior is controlled by an external state.
Custom Hook: A function that encapsulates reusable logic and returns a value.
Getter: A function that returns multiple props.
State Reducer: A function that can overload any internal action of a component.
EsLint: A tool for identifying and reporting on patterns found in ECMAScript/JavaScript code.
Prettier: A tool to format code consistently.
JSX: A syntax extension to JavaScript used with React to describe what the user interface should look like.
Context: A way to pass data through the component tree without having to pass props down manually at every level.
