[joeawillis]

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

[joeawillis]

This major version upgrade introduces several significant dependency updates and configuration changes. Key breaking changes include dropping support for Node.js 8, upgrading to ESLint 7 with new rules, and enabling Fast Refresh by default, which replaces React Hot Loader.

Highlights:

• ESLint 7: New linting rules are included, such as import/no-anonymous-default-export, which may require code changes. The EXTEND_ESLINT flag is no longer needed for custom configurations.
• Node.js 8 Deprecation: Support for Node.js 8 is removed.

Source: Create React App documentation
Recommendation: Manually update peer dependencies like React to v17, address new ESLint violations, and verify the application works with the new Fast Refresh feature.
