程序化用法

• Arborist 的 Node 类有一个 .querySelectorAll() 方法
  • 此方法将根据有效的查询选择器返回过滤的、扁平的依赖 Arborist Node 列表

const Arborist = require('@npmcli/arborist')
const arb = new Arborist({})

// root-level
arb.loadActual().then(async (tree) => {
  // query all production dependencies
  const results = await tree.querySelectorAll('.prod')
  console.log(results)
})

// iterative
arb.loadActual().then(async (tree) => {
  // query for the deduped version of react
  const results = await tree.querySelectorAll('#react:not(:deduped)')
  // query the deduped react for git deps
  const deps = await results[0].querySelectorAll(':type(git)')
  console.log(deps)
})
