link-workspace-packages

在单体仓库中链接工作区包（npm、Yarn、pnpm、bun）。适用场景：(1) 刚刚创建或生成新包，需要配置其依赖关系；(2) 用户从同级包中导入，需要将其添加为依赖项；(3) 在处理工作区包（@quiztime/*）时，遇到解析错误，如“无法找到模块”、“未能解析导入”、“TS2307”或“无法解析”。切勿通过修改tsconfig路径或手动编辑package.json来绕过问题——应使用包管理器的工作区命令，彻底解决实际的链接问题。

description: 'Link workspace packages in monorepos (npm, yarn, pnpm, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@quiztime/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager''s workspace commands to fix actual linking.'

Link Workspace Packages

Add dependencies between packages in a monorepo. All package managers support workspaces but with different syntax.

Detect Package Manager

Check whether there's a packageManager field in the root-level package.json.

Alternatively check lockfile in repo root:

  • •pnpm-lock.yaml → pnpm
  • •yarn.lock → yarn
  • •bun.lock / bun.lockb → bun
  • •package-lock.json → npm

Workflow

  1. •Identify consumer package (the one importing)
  2. •Identify provider package(s) (being imported)
  3. •Add dependency using package manager's workspace syntax
  4. •Verify symlinks created in consumer's node_modules/

pnpm

Uses workspace: protocol - symlinks only created when explicitly declared.

bash
# From consumer directory
pnpm add @quiztime/ui --workspace

# Or with --filter from anywhere
pnpm add @quiztime/ui --filter @quiztime/app --workspace

Result in package.json:

json
{ "dependencies": { "@quiztime/ui": "workspace:*" } }

yarn (v2+/berry)

Also uses workspace: protocol.

bash
yarn workspace @quiztime/app add @quiztime/ui

Result in package.json:

json
{ "dependencies": { "@quiztime/ui": "workspace:^" } }

npm

No workspace: protocol. npm auto-symlinks workspace packages.

bash
npm install @quiztime/ui --workspace @quiztime/app

Result in package.json:

json
{ "dependencies": { "@quiztime/ui": "*" } }

npm resolves to local workspace automatically during install.

bun

Supports workspace: protocol (pnpm-compatible).

bash
cd packages/app && bun add @quiztime/ui

Result in package.json:

json
{ "dependencies": { "@quiztime/ui": "workspace:*" } }

Examples

Example 1: pnpm - link ui lib to app

bash
pnpm add @quiztime/ui --filter @quiztime/app --workspace

Example 2: npm - link multiple packages

bash
npm install @quiztime/data-access @quiztime/ui --workspace @quiztime/dashboard

Example 3: Debug "Cannot find module"

  1. •Check if dependency is declared in consumer's package.json
  2. •If not, add it using appropriate command above
  3. •Run install (pnpm install, npm install, etc.)

Notes

  • •Symlinks appear in <consumer>/node_modules/@quiztime/<package>
  • •Hoisting differs by manager:
    • •npm/bun: hoist shared deps to root node_modules
    • •pnpm: no hoisting (strict isolation, prevents phantom deps)
    • •yarn berry: uses Plug'n'Play by default (no node_modules)
  • •Root package.json should have "private": true to prevent accidental publish
