What it is

Material UI is a production-grade React component library implementing Google's Material Design system. It provides pre-built, accessible UI components (Accordion, Alert, Autocomplete, etc.) with built-in theming and styling, eliminating the need to build design systems from scratch. The repository also includes a codemod tool (packages/mui-codemod) for automating deprecation migrations across major versions. Monorepo structure with packages/ containing separate concerns: packages/mui-codemod/ houses the deprecation-migration engine with modular transformers for each component (accordion, alert, autocomplete, etc.), each with actual.js/expected.js test cases and PostCSS plugins for…

Start here

Open these first:

• packages/mui-codemod/src/codemod.js — Entry point for the codemod tool that orchestrates deprecation transformations across the Material UI codebase.
• packages/mui-codemod/src/deprecations/all/deprecations-all.js — Master aggregator that applies all deprecation codemods in sequence; critical for bulk migration operations.
• packages/mui-codemod/src/deprecations/accordion-props/accordion-props.js — Template implementation for property-based deprecation transformations used across multiple component codemods.
• packages/mui-codemod/src/deprecations/accordion-summary-classes/postcss-plugin.js — CSS class name transformation plugin establishing the pattern for all CSS-based deprecation migrations.
• packages/mui-codemod/src/deprecations/button-classes/button-classes.js — Representative codemod for component class migrations demonstrating the dual-layer transformation (JS and CSS).

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone the repository and install dependencies using npm or yarn (conventional Node.js monorepo setup). Exact commands: git clone https://github.com/mui/material-ui.git && cd material-ui && npm install (or `yarn instal…

Daily commands:

Cannot infer exact dev server command from provided file list (no package.json root shown). Standard monorepo pattern: npm install at root, then npm run dev or npm run build. For codemod-specific work: navigate to…

…shortened for this brief.

Key cautions & unknowns

• No obvious environment variables or service dependencies evident from file list. However: (1) PostCSS and AST tooling require Node.js version compatibility—verify Node.js version in CI config before running locally.…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
