🚀 Introducing Prism Guard — An Open Source Frontend Architecture Intelligence Platform

#opensource #webperf #architecture #react

Every engineering team has experienced this.

The codebase starts clean.

A few months later...

Components become 500+ lines long.
Anonymous components start appearing everywhere.
Inline callbacks cause unnecessary re-renders.
Array index keys sneak into production.
Large synchronous imports increase bundle size.
Circular dependencies appear.
Feature boundaries slowly disappear.
Performance regressions are only discovered after deployment.

None of these issues are syntax errors.

None of them are TypeScript errors.

Most linters don't understand architectural intent.

By the time they're discovered during code reviews, they're already spread across the codebase.

That's why I built Prism Guard.

Prism Guard is an open-source Frontend Architecture Intelligence Platform for React and TypeScript projects.

Instead of only checking formatting or syntax, it analyzes your codebase for architectural, performance, and React best-practice violations.

Current capabilities

✅ React architecture rules

Nested Components
Inline JSX callbacks
Anonymous Components
Array Index Keys
Excessive useEffect
Large Components
Unstable Context Providers

✅ Performance analysis

Expensive renders
Bundle budget checks
Heavy synchronous imports
Missing lazy loading
Dynamic import recommendations

✅ Architecture analysis

Circular dependencies
Feature boundary violations
Folder structure validation
Component complexity
Excessive props
Dependency direction
Duplicate hooks
Cognitive complexity
Reports
Interactive Console Report
HTML Dashboard
JSON Output
SARIF Output (GitHub Code Scanning ready)
Configurable

Customize rules using a simple prism.config.json.

Example:

{ "react": { "maxHooks": 3, "maxComponentLines": 250 } } Installation npm install -D @prism-guard/cli

Run:

`npx prism-guard analyze`

Why I built it

After spending years building large-scale frontend platforms, micro-frontends, and design systems, I noticed that most teams have excellent tooling for:

Formatting
Linting
Unit testing
Type checking

…but very little that continuously enforces frontend architecture.

Prism Guard aims to fill that gap.

Roadmap

The first release is only the beginning.

Next up:

GitHub Action
VS Code Extension
AI-powered fix suggestions
Custom Rule SDK
Plugin ecosystem
Enterprise dashboards
It's Open Source ❤️

I'd love feedback from the community.
