What is mini-create-react-context?

The mini-create-react-context package is a smaller implementation of the React Context API. It provides a way to pass data through the component tree without having to pass props down manually at every level. This package is particularly useful for managing state in a global context, such as theming, localization, or user authentication data.

What are mini-create-react-context's main functionalities?

Creating a context

This feature allows you to create a new context object. You can provide a default value that can be used when a component does not have a matching Provider above it in the tree.

{"import createReactContext from 'mini-create-react-context';\nconst MyContext = createReactContext(defaultValue);"}

Provider Component

The Provider component is used to wrap a part of your application where you want the context to be accessible. It accepts a 'value' prop that will be passed down to consuming components.

{"import React from 'react';\nimport { MyContext } from './MyContext';\n\nconst App = () => (\n  <MyContext.Provider value={/* some value */}>\n    {/* children components that can consume the context */}\n  </MyContext.Provider>\n);"}

Consumer Component

The Consumer component is used to access the context value provided by the nearest Provider above in the tree. It uses a render prop to provide the context value to your component.

{"import React from 'react';\nimport { MyContext } from './MyContext';\n\nconst MyComponent = () => (\n  <MyContext.Consumer>\n    {value => /* render something based on the context value */}\n  </MyContext.Consumer>\n);"}
