React Context API

React-context-API

This repo contains a short story for learning purposes about the React Context API which provides a way to pass data through our different components without having to pass down props manually at every level. In plain english, Context API allows you pass state across the app without having to use props

Note: its better to props if you have just a few levels of children to pass.

How does it really work?

You create a context using React.createContext(), which returns a Context object

• context.js

Then you create a parent component that returns a Provider component

• index.js

Then add as children all the components from which you want to access the context, in this case

• Form is a child component that also has another component called Error which can also be referred to as the GrandChild of index which is the parent component

This is just a very basic example, read more about Context API here https://reactjs.org/docs/context.html

How to install:

• Clone the repository and change directory into the folder git clone && cd react-context-api

• Install project dependencies npm install

• Then start the server npm run start
