按键值对分组，同时使用ramda合并重复项

Question

我有一系列表单错误，如下所示：

[
  {
    "path": "email",
    "message": "email must be at least 10 characters",
  },
  {
    "path": "email",
    "message": "email must be a valid email",
  },
  {
    "path": "password",
    "message": "password must be at least 8 characters",
  }
]

需要对形状进行转换，使其符合表单的错误API。我想做的是使用ramda对其进行转换，使其最终结果如下：

{
  email: ["email must be at least 10 characters", "email must be a valid email"],
  password: ["password must be at least 8 characters"]
}

ramda函数用于实现此目的的最佳选择是什么？

Answer 1

使用R.pipe（或R.compose）创建一个按path属性（通过R.prop）分组的函数，然后在R.pluck中使用R.map来获取每组中的message属性：

const { pipe, groupBy, prop, map, pluck } = R

const fn = pipe(
  groupBy(prop('path')),
  map(pluck('message'))
)

const data = [{"path":"email","message":"email must be at least 10 characters"},{"path":"email","message":"email must be a valid email"},{"path":"password","message":"password must be at least 8 characters"}]

const result = fn(data)

console.log(result)
