Important Note About the Petfinder API

This course now uses an internal mock of the Petfinder API.

The Petfinder API was updated to v2, and the v1 API (used in this course) was deprecated. The Petfinder Client API library was updated to return hardcoded, mock results to simulate the Petfinder API live response.

Don't worry, all course code still works as in the videos! 😀

Note: If you started the course before April 2nd, 2019, you'll need to update your Petfinder Client (petfinder-client) to v1.0.1 in your package.json, delete your package-lock.json and run npm install. See: https://github.com/btholt/complete-intro-to-react-v4/blob/master/package.json#L38

Debugging

Parcel is an ever evolving project that's just getting better. If you run into problems with it not respecting changes (particularly to your .babelrc or .env files) then delete the dist/ and the .cache/ directories. You can do this in bash by running from the root directoy of your project rm -rf dist/ .cache/ or just by deleting those directories in your editor. This will force Parcel to start over and not cache anything.

See this issue for more specific instructions.

If you run into anything else, open an issue and we'll try to clarify or help.
