[使用ng-build输出–??dev]

这是我的package.json

  }
}

对于prod构建,供应商包已集成在主包中,因为它默认使用构建优化器.

根据angular-cli documentation：

Total bundle sizes with Build Optimizer are smaller if there is no separate vendor chunk because having vendor code in the same chunk as app code makes it possible for Uglify to remove more unused code.
