Hello World example
This example shows how to use react context api in our app.
It provides an example of using pages/_app.js
to include the context api provider and then shows how both the pages/index.js
and pages/about.js
can both share the same data using the context api consumer.
We start of by creating two contexts. One that actually never changes (CounterDispatchContext
) and one that changes more often (CounterStateContext
).
The pages/index.js
shows how to, from the home page, increment and decrement the context data by 1 (a hard code value in the context provider itself).
The pages/about.js
shows how to pass an increment value from the about page into the context provider itself.
