+# Data Fetching in Decoupled React + Drupal
+
+[back to main project README](../../README.md)
+
+## Summary
+
+The goal for this exercise is to create a React app in Drupal that can fetch data from Drupal using the Drupal JSON API. We'll also look at loading data from an external API.
+
+For an extra challenge, you may use a data fetching library to handle loading states, errors states, and client-side caching.
+
+## Acceptance Criteria
+
+- Add a new React app in Drupal as a block module 
+  - This can be a new module or feel free to reuse the same custom module from [Part 1](./1-create-custom-react-block.md)
+- Sample content has been added to drupal. 
+  - The [Devel module](https://www.drupal.org/docs/contributed-modules/devel) can be useful for generating sample content, but you may also add content manually through the Drupal admin.
+- The JSON API module has been enabled in Drupal
+- A fetch request is being made from the The React app to the Drupal JSON API to load Drupal content in our React app.
+- A fetch request is being made from the React app to an external API to display non-drupal content in the same React app.
+  - The [PokeAPI](https://pokeapi.co/) is excellent for an external API option
+- [Challenge] A data fetching library is used to handle loading and error states for  fetch requests.
+- [Challenge] A data fetching library is used handle client-side caching.
+[TanStack Query](https://tanstack.com/query/latest) is recommended for both Challenge criteria, but there are many other libraries that solve similar problems.
