[shivpathak-teg]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• example/package.json
• example/yarn.lock

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

Vulnerabilities that will be fixed with an upgrade:

🦉 Directory Traversal

[shivpathak-teg]

This major version upgrade introduces several notable breaking changes by updating underlying tools like ESLint, Jest, and React. It also enables the new JSX Transform by default. While many projects can upgrade without issues, manual changes may be required, especially for projects with customized ESLint configurations or older testing setups.

Highlights:

• ESLint 7 Upgrade: New linting rules have been added, including for React Testing Library. The EXTEND_ESLINT environment variable is no longer needed for custom configurations.
• New JSX Transform: Projects no longer need to import React in every file just to use JSX.

Source: Create React App Changelog
Recommendation: After upgrading, delete the node_modules folder and package-lock.json file, then run npm install. Review and update any custom ESLint rules to be compatible with ESLint 7.
