fix: exclude build artifacts to prevent 250MB limit errors in monorepos

[daviddaytw]

Problem

When using vercel-php in modern monorepo setups (Turbo, Next.js, Nuxt, SvelteKit, etc.), deployments fail with:

Error: A Serverless Function has exceeded the unzipped maximum size of 250 MB

Root Cause

The PHP runtime bundles all files from workPath into each serverless function, excluding only:

• node_modules/**
• Vercel config files

Modern frameworks generate large build artifacts (.next/, .turbo/, etc.) that weren't common when this runtime was created. These directories get included in every PHP function, causing massive bundle sizes.

Real-World Example

In a Turbo monorepo with Next.js:

• .next/ folder: 662 MB (mostly webpack cache)
• Result: Each PHP function tries to bundle this → deployment fails
• After fix: PHP functions are ~38 MB → deployment succeeds ✅

Solution

Update the default excludeFiles list to exclude common modern build directories:

• .next/** - Next.js build output
• .turbo/** - Turbo cache
• dist/** - Common build output
• .cache/** - General build caches
• .nuxt/** - Nuxt.js build
• .svelte-kit/** - SvelteKit build
• .output/** - Nitro/Nuxt output

Additional Context

This issue became prominent with the rise of:

• Monorepo tooling (Turbo, Nx, Rush)
• Aggressive build caching strategies

I agree with all of them, but dist can be useful. If you need some resources for PHP, for example geoip.json, I think you can place it to data or dist or something like that. Ignoring dist folder can be hidden problem. WDYT?

If someone want to ignore it, you can use excludeFiles.
