Add custom ESLint rule for pattern-based import restrictions

[Copilot]

Adds material-ui/no-restricted-imports rule to replace complex no-restricted-imports configurations with robust glob pattern matching on import source strings.

Implementation

• Rule: packages/code-infra/src/eslint/material-ui/rules/no-restricted-imports.mjs

  • Restricts imports by source string patterns (e.g., '@mui/material/Box') rather than resolved file paths
  • Uses minimatch for glob patterns: @mui/material/*, @mui/*/internal/**, ./**/*.css
  • Supports custom error messages per pattern
  • Handles both ESM (import) and CommonJS (require())

• Tests: 17 test cases covering glob patterns, wildcards, named/namespace imports, CommonJS, custom messages

• Export: Added to material-ui plugin in index.mjs

• Documentation: Added ESLint plugin section to README with usage examples

Usage

// eslint.config.mjs
{
  rules: {
    'material-ui/no-restricted-imports': [
      'error',
      [
        {
          pattern: '@mui/material/*',
          message: 'Use the default import from @mui/material instead.'
        },
        {
          pattern: '@mui/*/internal/**',
          message: 'Do not import from internal modules.'
        }
      ]
    ]
  }
}

Comparison with existing rule

no-restricted-resolved-imports matches resolved file paths (after module resolution). This new rule matches import source strings directly, making it more suitable for restricting module/package imports by pattern.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• iojs.org
  • Triggering command: curl --fail --compressed -q -L -s REDACTED -o - (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Summary

We've been using no-restricted-imports with complex configuration to restrict certain import paths. Makes sense to have a more robust rule specific to the use case.
