Bun Runtime Integration

Running your monorepo with Bun for blazing fast speeds

Tool Bun Install Bun Script Run Known Quirks
pnpm ✅ native_completion = true ✅ Fully supported Works perfectly, nothing fancy needed
NX ✅ Uses pnpm by default ✅ Custom executors work May need tweaks for non-Node runtimes
Turborepo ✅ Uses whatever you configure ✅ Pipeline supports bun run Needs custom pipeline definition
Lerna ✅ Works fine ⚠️ Indirect support Scripts execution depends on underlying package manager
Rush ✅ PnP with Bun possible ⚠️ Untested waters Not officially tested, proceed carefully
Changesets N/A (publish only) N/A Plays nice with Bun if paired with Turbo or pnpm

🏭 NestJS-Specific Considerations

Nx + NestJS

The clear winner for NestJS projects. They maintain an official @nx/nest plugin with:

  • Generators for modules/controller/service
  • ESLint configuration baked in
  • Compilation executor ready out of the box
  • Test setup with Jest completely handled

Turborepo + NestJS

Totally workable but you'll need to roll your own configuration:

  • Define custom pipeline for nest build
  • Wire up your own TypeScript configs
  • Integrate ESLint through Turborepo tasks
  • Overall: more manual work, same eventual outcome

pnpm + NestJS

Lean choice if you want less abstraction:

  • nest-cli is already Node-based
  • Dependencies all resolved by pnpm natively
  • Just add scripts to package.json in each app
  • Zero magic, all control

Recommended Setup By Project Size

One size definitely doesn't fit all. Here's what we'd recommend depending on your team size, ambition, and how much complexity you want managing.

SMALL Solo Developer or Small Team (2-5 devs)

You've got a modest app, maybe a Vue frontend talking to a single NestJS API. You're prioritizing velocity and don't want infrastructure headaches.

Top Pick: pnpm Workspaces

This combo keeps things dead simple:

  1. 1Install Bun globally, then install pnpm via bun add -g pnpm
  2. 2Run pnpm init in root
  3. 3Add packages: * and create folders structure
  4. 4Done. Start adding Vue/NestJS packages instantly

Runner Up: Turborepo

If you want that sweet caching action but with minimal fuss, Turborepo is practically zero-setup and gives you incredible build acceleration from day one. Works nicely with Bun.

LARGE Growing Team (10-50+ devs)

Now you're cooking with gas—multiple apps, shared UI component lib, several backend services, published packages for others to consume. That's when the serious tooling becomes worthwhile.

Top Pick: Nx + pnpm + Changesets

This trio is the heavyweight champion combo:

  1. 1Initialize Nx with npx create-nx-workspace@latest
  2. 2Pick Integrated repo type
  3. 3Choose apps & libs preset
  4. 4Select pnpm for package manager
  5. 5Add Changesets for releases via pnpm add -Dw @changesets/cli

Alternative: Turborepo + pnpm + Changesets

If Nx feels heavy or you want Vercel's blazing speeds, swap Nx for Turborepo while keeping pnpm and Changesets. Same publishing power, fresher DX.

💡 Pro tip: If you're leaning enterprise-hard, consider switching from pnpm to Rush for the symlink-less PnP world and Microsoft-level engineering rigor—but expect a steep ramp-up.

🎯 Quick Decision Framework

Q1:
Is your primary goal shipping Vue + NestJS apps quickly without monorepo overhead?
→ YES:
Use pnpm workspaces. Done. Move on with your life.
→ NO:
Continue to Q2...
Q2:
Are there going to be more than ~3 apps OR will you have shared packages getting published?
→ YES:
Jump to decision on complexity tolerance below ⤵
→ NO:
Consider Turborepo for caching wins with reasonable effort.
Q3:
Would you rather spend time coding features or configuring build systems?
→ Code features:
Go Nx – pays back in automation once configured.
→ Configure builds:
Pick pnpm workspaces + Changesets – lean but effective.

Sample Architecture Patterns

Concrete folder structures to inspire your layout. These are battle-tested patterns from real-world Vue + NestJS monorepos.

Pattern A: Classic Apps + Libs

Apps
apps/web
Vue 3 SPA
apps/mobile
Vue 3 Mobile
apps/api
NestJS API
→
Packages
libs/ui
Shared Vue components
libs/api-client
Typed API client
libs/utils
Shared utilities
→
Config
tools
TS configs, ESLint, etc

Pattern B: Service-Oriented Backend

Apps
apps/web-app
Full-stack app
→
Services
services/auth
NestJS Auth MS
services/users
NestJS Users MS
services/content
NestJS CMS MS
→
Shared
shared/types
DTOs, interfaces
shared/config
Env, constants

📄 Sample Configuration Files

pnpm-workspace.yaml 
packages:
  - 'apps/*'
  - 'packages/*'
nx.json 
{
  "targetDefaults": {
    "build": {
      "dependsOn": ["^build"]
    },
    "lint": { "inputs": ["{projectRoot}/**/*.ts"] },
    "test": { "inputs": ["{projectRoot}/**/*.ts"] }
  }
}
turbo.json 
{
  "pipeline": {
    "build": { "dependsOn": ["^build"], "outputs": ["dist/**"] },
    "test": { "dependsOn": ["build"], "outputs": ["coverage/**"] },
    "lint": { "outputs": [] },
    "dev": { "cache": false, "persistent": true }
  }
}

🔄 Migrating Between Tools

Worried about being locked in? Good news—these tools play nicer together than you'd think:

From pnpm → Nx

Keep your packages folder layout—just run npx nx init in the repository root. Nx respects the exact same folder structure. Drop it in, and watch the plugins detect all your packages automatically.

From Turborepo → Nx

Export your pipeline definitions to Nx executors—you'll effectively gain more sophisticated graph intelligence. The actual package contents stay untouched, only the orchestration layer moves.

Lerna → Others

Most migrations paths involve adding either Nx or Turborepo alongside. The Lerna-managed publications migrate cleanly to Changesets—their changelog entry approach is widely considered superior anyway.
