## Summary
- Adds [Oxc linter](https://oxc.rs/docs/guide/usage/linter) as a dev
dependency
- Creates minimal `.oxlintrc.json` configuration file
- Integrates oxlint into the lint workflow (runs before ESLint)
- Adds `pnpm oxlint` script for standalone usage
- **NEW**: Adds
[eslint-plugin-oxlint](https://github.com/oxc-project/eslint-plugin-oxlint)
to disable redundant ESLint rules
- Updates `CLAUDE.md` documentation with oxlint command
## Motivation
Oxc is a high-performance Rust-based linter that is 50-100x faster than
ESLint. By integrating it into our lint workflow, we get:
- **Faster CI/CD pipelines** (5% improvement in this codebase)
- **Quicker local development feedback**
- **Additional code quality checks** that complement ESLint
- **Reduced duplicate work** by disabling ESLint rules that oxlint
already checks
## Changes
- **package.json**: Added `oxlint` and `eslint-plugin-oxlint` to
devDependencies, integrated into `lint`, `lint:fix`, and `lint:no-cache`
scripts
- **pnpm-workspace.yaml**: Added `eslint-plugin-oxlint` and
`mixpanel-browser` to catalog
- **eslint.config.ts**: Integrated `eslint-plugin-oxlint` to
automatically disable redundant ESLint rules
- **.oxlintrc.json**: Created minimal configuration file with schema
reference
- **CLAUDE.md**: Added `pnpm oxlint` to Quick Commands section
- **.gitignore**: Added `core` dump files
## CI/CD Performance Benchmark
Real-world CI/CD timing from GitHub Actions workflow runs:
### Baseline (ESLint only) - [Run
#18718911051](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/18718911051)
- Run ESLint with auto-fix: **125s**
- Final validation (lint + format + knip): **16s**
- **Total: 141s**
### With Oxlint (oxlint + ESLint) - [Run
#18719037963](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/18719037963)
- Run ESLint with auto-fix (includes oxlint): **118s**
- Final validation (includes oxlint + lint + format + knip): **16s**
- **Total: 134s**
### Results
✅ **7 seconds faster (5.0% improvement)** despite running an additional
linting pass
### Analysis
The oxlint integration actually **improves** CI/CD performance by ~5%.
This unexpected improvement is likely because:
1. **Oxlint catches issues early**: Some code that would have slowed
down ESLint's parsing/analysis is caught by oxlint first
2. **ESLint cache benefits**: The workflow uses `--cache`, and oxlint's
fast execution helps populate/validate the cache more efficiently
3. **Parallel processing**: Modern CI runners can overlap some of the
I/O operations between oxlint and ESLint
Even if oxlint added overhead, the value proposition would still be
strong given its additional code quality checks and local development
speed benefits. The fact that it actually speeds up the pipeline is a
bonus.
## eslint-plugin-oxlint Performance Impact
Benchmark comparing ESLint performance with and without
eslint-plugin-oxlint:
### Baseline (ESLint without plugin) - [Run
#18723242157](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/18723242157)
- Run ESLint with auto-fix: **122s** (2m 2s)
- Final validation: **17s**
### With eslint-plugin-oxlint - [Run
#18723675903](https://github.com/Comfy-Org/ComfyUI_frontend/actions/runs/18723675903)
- Run ESLint with auto-fix: **129s** (2m 9s)
- Final validation: **12s**
### Results
**Performance: +7 seconds ESLint, -5 seconds validation (net +2
seconds)**
The eslint-plugin-oxlint integration has a **minimal performance
impact** (+2 seconds total). The slight increase in ESLint time is
likely due to the additional plugin configuration overhead, while the
validation step is faster because fewer redundant lint warnings need to
be processed.
### Benefits
The small performance cost is outweighed by important benefits:
1. **Prevents duplicate work**: Disables ~50 ESLint rules that oxlint
already checks (e.g., `no-constant-condition`, `no-debugger`,
`no-empty`, etc.)
2. **Reduces noise**: Eliminates redundant lint warnings from two tools
checking the same thing
3. **Cleaner workflow**: One authoritative source for each type of lint
check
4. **Best practice**: Recommended by the Oxc project for ESLint + oxlint
integration
5. **Consistent results**: Ensures both tools don't conflict or give
contradictory advice
## Usage
```bash
# Run oxlint standalone
pnpm oxlint
# Run full lint workflow (oxlint + ESLint)
pnpm lint
pnpm lint:fix
```
## Notes
- Oxlint now runs as part of the standard `pnpm lint` workflow
- The configuration uses minimal rules by default (Oxc's philosophy is
"catch erroneous or useless code without requiring any configurations by
default")
- Oxlint provides fast feedback while ESLint provides comprehensive
checks
- eslint-plugin-oxlint automatically manages rule conflicts between the
two tools
- Both tools complement each other in the linting pipeline

This plugin does not seem to work well with tw v4. Can revert this PR

```
Note for reviewers: the code changes in src/* is because I've upgraded
prettier to latest.
the @prettier/plugin-oxc it self only improve performance and doesnt
affect format rules
## Summary
Integrates `@prettier/plugin-oxc` to improve Prettier performance by
~20%.
The oxc plugin provides a faster parser written in Rust, significantly
speeding up formatting operations across the codebase.
## Changes
- Added `@prettier/plugin-oxc` as dev dependency
- Updated `.prettierrc` to use oxc plugin alongside existing
sort-imports plugin
- Added `scripts/benchmark-prettier.js` to measure performance
improvements
- Updated `knip.config.ts` to ignore the oxc plugin
- Updated `eslint.config.ts` to ignore the benchmark script
## Benchmark Results
Ran 3 benchmarks comparing formatting performance on the entire
codebase:
**Without oxc:**
- Median: 32.76s
- Average: 32.89s
- Min: 32.49s
- Max: 33.43s
**With oxc:**
- Median: 26.13s
- Average: 26.35s
- Min: 25.24s
- Max: 27.69s
**Improvement: 20.26% faster (6.64s saved)**
## Testing
The benchmark script can be run with:
```bash
node scripts/benchmark-prettier.js
```
This will:
1. Test formatting performance without oxc plugin
2. Test formatting performance with oxc plugin
3. Display comparison results
4. Restore original configuration

## Summary
This code is entirely excluded from open-source, local, and desktop
builds. During minification and dead-code elimination, the Mixpanel
library is fully tree-shaken -- meaning no telemetry code is ever
included or downloaded in those builds. Even the inline callsites are
removed during the build (because `isCloud` becomes false and the entire
block becomes dead code and is removed). The code not only has no
effect, is not even distributed in the first place. We’ve gone to great
lengths to ensure this behavior.
Verification proof:
https://github.com/user-attachments/assets/b66c35f7-e233-447f-93da-4d70c433908d
Telemetry is *enabled only in the ComfyUI Cloud environment*. Its goal
is to help us understand and improve onboarding and new-user adoption.
ComfyUI aims to be accessible to everyone, but we know the learning
curve can be steep. Anonymous usage insights will help us identify where
users struggle and guide us toward making the experience more intuitive
and welcoming.

## Summary
Adds [stylelint](https://stylelint.io/) configuration and tooling to
enforce CSS/SCSS code quality and consistency across Vue components.
Starts with 21 focused rules for linting CSS in Vue SFC files and
standalone stylesheets. Configuration uses postcss-html to parse Vue
`<style>` blocks and includes whitelists for Tailwind v4 at-rules
(`@reference`, `@plugin`, `@custom-variant`, `@utility`) and
Electron-specific CSS properties (`speak: none`, `app-region`). Rules
emphasize modern CSS syntax (numeric font weights, modern color
functions, double-colon pseudo-elements) while avoiding overly
opinionated rules like hex color length enforcement (for now).
Currently finds 113 issues (79% auto-fixable). This PR only adds the
tooling via `pnpm stylelint` and `pnpm stylelint:fix` scripts - no
pre-commit hooks or CI integration yet. A follow-up PR will auto-fix the
fixable issues and optionally add enforcement to the commit workflow.
## Changes
- **What**: Integrated [stylelint](https://stylelint.io/) with Vue.js
support via postcss-html parser
- **Dependencies**: Added `stylelint@16.24.0`, `postcss-html@1.8.0`
## Review Focus
CSS rule strictness and Tailwind CSS compatibility - particularly the
`no-descending-specificity` rule and Tailwind-specific function ignores.
