Research: Node.js v24.15.0 Upgrade

Research Topics Completed

RT-001: Node.js v24 Breaking Changes

Decision: Use Node.js v24.15.0 LTS

Rationale:

• v24.15.0 is the current LTS (Long Term Support) version
• Extended support through April 2027
• Security patches and performance improvements over v22.x

Breaking Changes Assessment:

Change	Impact on NAP-DMS	Action Required
Permission Model experimental changes	None	ไม่ใช้ permission model
Buffer() constructor deprecation	Low	Check legacy code; migrate to Buffer.from()
Crypto algorithm deprecations	Low	Verify hash usage in auth modules
url.parse() deprecation	None	ใช้ new URL() อยู่แล้ว
Test runner changes	None	Jest ไม่ใช้ Node.js native test runner

Alternatives Considered:

• v23.x (not LTS, not suitable for production)
• Stay on v22.x (End-of-Life April 2026, security risk)

RT-002: Native Module Compatibility

Decision: Current native dependencies are compatible with Node.js v24

Rationale: N-API v8+ provides stability across Node.js versions

Compatibility Matrix:

Package	Current Version	Node v24 Support	N-API Level
bcrypt	^5.1.1	✅ Supported	N-API v8
sharp	^0.33.x	✅ Supported	N-API v8
sqlite3	^5.1.6	✅ Supported	node-gyp
argon2	^0.40.0	✅ Supported	N-API
@nestjs/platform-socket.io	^10.x	✅ Supported	Pure JS
class-validator	^0.14.x	✅ Supported	Pure JS

Validation Plan:

1. Run pnpm rebuild in staging environment
2. Verify all native modules load without errors
3. Run integration tests involving native modules

Alternatives Considered:

• Use pure-JS alternatives (slower performance)
• Pin to older native module versions (security risk)

RT-003: pnpm Compatibility

Decision: pnpm 9.x fully supports Node.js v24

Rationale: pnpm maintains compatibility across Node.js LTS versions (18, 20, 22, 24)

Findings:

• pnpm 9.0.0+ officially supports Node.js 18-24
• No known issues with pnpm on Node.js v24
• Lockfile format v9 is compatible

Alternatives Considered:

• Switch to npm (unnecessary disruption, slower)
• Switch to yarn (no significant benefit)

---

RT-004: Docker Image Availability

Decision: Use node:24.15.0-alpine3.21

Rationale:

• Alpine-based images are ~190MB compressed (vs ~1GB for full image)
• Alpine 3.21 is the latest stable
• Includes libc6-compat for native module compatibility

Image Options Compared:

Image	Size	Pros	Cons
node:24.15.0-alpine3.21	~190MB	Small, secure	Need libc6-compat for some native modules
node:24.15.0-slim	~250MB	Debian-based, more compatible	Larger
node:24.15.0	~1GB	Full compatibility	Very large, unnecessary

Dockerfile Updates Required:

# Before
FROM node:22.20.0-alpine3.20

# After
FROM node:24.15.0-alpine3.21

Additional Findings

NestJS Compatibility

• NestJS 10.x fully supports Node.js v24
• No breaking changes in NestJS core
• @nestjs/swagger, @nestjs/typeorm work correctly

Next.js Compatibility

• Next.js 14.x supports Node.js v24
• Next.js 15.x optimized for Node.js v24+ (future upgrade opportunity)
• Build performance may improve on v24

Performance Expectations

Node.js v24 improvements vs v22:

• ~5-10% faster HTTP throughput
• Improved memory management
• Faster startup time for ES modules

Target: Stay within 5% of baseline (may actually improve)
