NPM

tip
  • NODE_ENV=production 或 --production 时 npm ci/install 不会安装开发依赖
    • npm ci --include=dev 强制安装 dev
建议限定版本

  "engines": {
    "node": "14",

  }
}
du -hs ~/.npm/_cacache/ # 查看本地缓存大小
npm config get prefix   # bin 目录
npm list -g --depth=0   # 全局模块 - 第一行为目录，例如 /usr/local/lib
npm root -g

export NODE_PATH=$(npm root -g) # 能 import 全局的包
node -p process.config.variables.node_prefix

scope​

# 添加一个 scope
npm login --registry=https://reg.wener.me/nexus/repository/npm-internal/ --scope=@wener
# 添加后可修改关联的仓库
npm config set @wener:registry https://reg.wener.me/nexus/repository/npm-internal/
# 初始化时可以使用指定的 scope, 包名中会加上  @wener
npm init --scope=wener
# 发布是会发往 @wener 的仓库中
npm publish
# 安装指定 scope 中的模块
npm install @wener/wener-test
# 可以设置当前的全局 scope
npm config set scope wener

workspaces​

npm ls
# 添加依赖到 workspace
npm add -w @wener/apis-weaver systemjs
# 依赖另外一个 workspace - 不能在 module add - 会报找不到
npm add -w @wener/apis-weaver @wener/apis-core
# npx 在 ws 下执行
npx -w @wener/apis-weaver typesync
# run 在 ws 下执行 - 注意 path.resolve 还是基于 ws 路径而不是当前路径
npm run -w @wener/apis-weaver build
