Dependency Adding 500KB to Bundle Size
A small feature was added via npm package but bundle size increased 500KB. The feature doesn't justify the size increase. Build tools show the dependency is being included but it's rarely used, or lighter alternatives exist.
Adding the dependency solved a problem but created a new one: application loads slower for all users.
Error Messages You Might See
Bundle size warning: 500KB increase
Application load time increased significantly
Entry bundle larger than expected
Common Causes
- Package includes entire library when only one function is needed
- No tree-shaking configuration, entire package included despite partial use
- Dependency has heavy transitive dependencies (dependencies of dependencies)
- Duplicate dependencies at different versions in node_modules
- Development dependency accidentally included in production bundle
How to Fix It
Analyze bundle: webpack-bundle-analyzer, source-map-explorer show what takes space. Check package sizes on bundlephobia.com. Look for lighter alternatives. Use only needed exports: import { func } from 'lib' not import lib. Ensure devDependencies aren't bundled. Deduplicate: npm dedupe. Lazy load heavy dependencies.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

Get HelpFrequently Asked Questions
How to analyze what's in the bundle?
Use webpack-bundle-analyzer (webpack-bundle-analyzer plugin) or source-map-explorer. Visualizes what takes space.
Should all dependencies be in package.json?
devDependencies for build tools, testing. dependencies for runtime. Never mix them.
How to reduce dependency size?
Use lighter alternatives (lodash-es instead of lodash). Lazy load: const lib = () => import('heavy-lib'). Tree-shake unused code.
