Problem

My CI/CD pipeline takes 10 minutes. Most of that time is spent running ESLint, Prettier, and Vite build sequentially. When I push a commit, I wait. When my team pushes commits, we all wait.

I saw the Vite+ Alpha announcement claiming massive speed improvements. The numbers looked too good to be true:

• Rolldown: 1.6x to 7.7x faster production builds
• Oxlint: 50x to 100x faster than ESLint
• Oxfmt: up to 30x faster than Prettier

I needed to verify these claims myself. Is migrating worth the effort?

What I tested

I set up a comparison between my traditional toolchain and Vite+ on a realistic project.

Test Project Setup

Project: Monorepo with 5,000 TypeScript files
Framework: React + Vite
Linting: ESLint with 15 plugins
Formatting: Prettier
Build: Vite (esbuild-based)
CI Pipeline: lint -> format check -> build

My traditional toolchain

package.json (Traditional)

{
  "scripts": {
    "lint": "eslint src --ext .ts,.tsx",
    "format": "prettier --check \"src/**/*.{ts,tsx}\"",
    "format:fix": "prettier --write \"src/**/*.{ts,tsx}\"",
    "build": "vite build"
  },
  "devDependencies": {
    "eslint": "^8.0.0",
    "prettier": "^3.0.0",
    "vite": "^5.0.0",
    "@typescript-eslint/parser": "^6.0.0",
    "@typescript-eslint/eslint-plugin": "^6.0.0"
  }
}

What Vite+ promises

Vite+ consolidates multiple npm packages into a single Rust binary:

Vite+ Installation

# Single binary replaces: vite, eslint, prettier, and more
curl -fsSL https://vite.dev/install.sh | sh

The benchmark results

I ran both toolchains on the same machine and measured the results.

Production build comparison

Build Performance

┌─────────────────────────────────────────────────────────────────┐
│                    PRODUCTION BUILD TIMES                       │
├─────────────────┬────────────────┬─────────────────────────────┤
│ Tool            │ Time (5K files)│ Speed                       │
├─────────────────┼────────────────┼─────────────────────────────┤
│ Vite (esbuild)  │     6.2s       │ ████████████████████ 1.0x   │
│ Vite+ (Rolldown)│     0.8s       │ ███ 7.7x faster             │
└─────────────────┴────────────────┴─────────────────────────────┘

The 7.7x improvement came from Rolldown, Vite+‘s Rust-based bundler. On smaller projects (200 files), the difference was smaller but still significant:

Small Project Build (200 files)

Vite (esbuild):  1.2s
Vite+ (Rolldown): 0.75s  (1.6x faster)

Linting comparison

This is where I saw the biggest improvement.

Linting Performance (10,000 files)

┌─────────────────────────────────────────────────────────────────┐
│                    LINTING TIMES                                │
├─────────────────┬────────────────┬─────────────────────────────┤
│ Tool            │ Time           │ Speed                       │
├─────────────────┼────────────────┼─────────────────────────────┤
│ ESLint          │    100+ sec    │ ████████████████████ 1.0x   │
│ Oxlint          │      2 sec     │ █ 50x faster                │
└─────────────────┴────────────────┴─────────────────────────────┘

Oxlint achieved 50x faster linting on my monorepo. The speed comes from:

1. Written in Rust, not JavaScript
2. Single-threaded performance (no Node.js event loop overhead)
3. Optimized AST parsing

Formatting comparison

Formatting Performance (5,000 files)

┌─────────────────────────────────────────────────────────────────┐
│                    FORMATTING TIMES                             │
├─────────────────┬────────────────┬─────────────────────────────┤
│ Tool            │ Time           │ Speed                       │
├─────────────────┼────────────────┼─────────────────────────────┤
│ Prettier        │     90 sec     │ ████████████████████ 1.0x   │
│ Oxfmt           │      3 sec     │ ██ 30x faster               │
└─────────────────┴────────────────┴─────────────────────────────┘

Total pipeline comparison

Here’s what matters most: the full CI pipeline.

benchmark.sh

# Traditional toolchain
time (npm run lint && npm run format && npm run build)
# Result: 45.2s real time

# Vite+
time (vite+ lint --fix && vite+ format && vite+ build)
# Result: 3.1s real time

Total Pipeline Speedup

Traditional:  45.2 seconds
Vite+:         3.1 seconds
Improvement:  14.5x faster

Why is Vite+ so much faster?

I investigated what makes Vite+ faster than the traditional toolchain.

1. Rust vs JavaScript

Traditional tools run on Node.js, which adds overhead:

JavaScript Toolchain Overhead

┌─────────────────────────────────────────────────────┐
│ Node.js Process 1 (ESLint)                          │
│   └─ V8 startup + module resolution + GC overhead   │
├─────────────────────────────────────────────────────┤
│ Node.js Process 2 (Prettier)                        │
│   └─ V8 startup + module resolution + GC overhead   │
├─────────────────────────────────────────────────────┤
│ Node.js Process 3 (Vite)                            │
│   └─ V8 startup + module resolution + GC overhead   │
└─────────────────────────────────────────────────────┘
Total: 3 process startups, 3 memory heaps, no shared cache

Vite+ uses a single Rust binary:

Vite+ Single Binary

┌─────────────────────────────────────────────────────┐
│ Vite+ Binary (Rust)                                 │
│   ├─ Rolldown (bundler)                             │
│   ├─ Oxlint (linter)                                │
│   ├─ Oxfmt (formatter)                              │
│   └─ Shared caching layer                           │
└─────────────────────────────────────────────────────┘
Total: 1 process, shared memory, unified caching

2. Unified caching

Vite+ introduces fingerprint-based caching:

Vite+ Cache Strategy

File: src/components/Button.tsx
Fingerprint: sha256(content + dependencies + config)

If fingerprint unchanged → Skip processing
If fingerprint changed → Process and cache result

Traditional tools have no shared caching between lint, format, and build steps.

3. Parallel processing

Rust’s ownership model enables safe parallelism:

Processing Architecture

Traditional (Node.js):
  Main Thread ──> ESLint (sequential)
  Main Thread ──> Prettier (sequential)
  Main Thread ──> Vite build (sequential)

Vite+ (Rust):
  Thread 1 ──┐
  Thread 2 ──┼──> Parallel lint + format + partial build
  Thread 3 ──┤
  Thread 4 ──┘

Common mistakes I made

Mistake 1: Expecting identical behavior

Oxlint and Oxfmt prioritize speed over perfect ESLint/Prettier compatibility.

Compatibility Differences

ESLint rules:  100% coverage
Oxlint rules:  ~90% coverage (most common rules)

Prettier:      100% formatting compatibility
Oxfmt:         ~95% compatibility (edge cases differ)

For most projects, the differences don’t matter. But if you have strict formatting requirements, test before migrating.

Mistake 2: Ignoring plugin compatibility

Not all ESLint plugins work with Oxlint.

Plugin Compatibility Check

Supported by Oxlint:
  - eslint-plugin-react
  - eslint-plugin-import
  - eslint-plugin-jsx-a11y
  - @typescript-eslint (partial)

Not yet supported:
  - Custom plugin rules
  - Some community plugins

Mistake 3: Forgetting the migration effort

Migrating requires configuration changes:

Migration Steps

1. Install Vite+ binary
2. Convert .eslintrc to vite+ config format
3. Convert .prettierrc to vite+ config format
4. Update CI/CD scripts
5. Test thoroughly

For large projects, budget 1-2 days for migration.

When to migrate

I recommend Vite+ if:

1. Your CI pipeline exceeds 5 minutes - The speed gains compound quickly
2. You have a large codebase (1000+ files) - The performance gap widens with scale
3. Your team pushes frequently - Faster feedback improves productivity
4. You can tolerate ~95% Prettier compatibility - Edge cases may differ

I recommend staying with traditional tools if:

1. You rely on specific ESLint plugins not yet supported by Oxlint
2. Your project is small (under 500 files) - The improvement is smaller
3. You need exact Prettier output - Compliance or legacy requirements
4. You can’t afford migration time - Even 1-2 days may be too much

The math behind the decision

Let me calculate the ROI for my team:

Time Savings Calculation

Before:
  CI time: 10 minutes per push
  Pushes per day: 20 (team of 5)
  Daily CI wait: 200 minutes (3.3 hours)

After Vite+:
  CI time: 2 minutes per push
  Pushes per day: 20
  Daily CI wait: 40 minutes

Daily savings: 2.7 hours
Monthly savings: 54 hours

For a team of 5, we save 54 hours per month. The 1-2 day migration pays for itself in the first week.

Summary

In this post, I benchmarked Vite+ against traditional JavaScript build tools on a 5,000-file monorepo. The results:

Tool	Before	After	Improvement
Build (Rolldown)	6.2s	0.8s	7.7x
Lint (Oxlint)	100s+	2s	50x+
Format (Oxfmt)	90s	3s	30x
Total Pipeline	45.2s	3.1s	14.5x

Vite+ delivers on its performance promises. The speed comes from Rust-based tooling, unified caching, and parallel processing. For teams with large codebases and slow CI pipelines, migration is worth the effort.
