对 ramda.js 实用程序进行类型检查

Question

这段代码按预期工作，但它是一个类型错误富矿。是否真的可以有效地键入检查此代码，或者我应该放弃并

@ts-expect-error

一切？

我确实安装了

@types/ramda

，但它对此根本不满意，即使我确实有这些类型可用，我仍然发现，一般来说，尝试有效地输入 ramda 确实是非常毛茸茸的（否则我是一个大图书馆的粉丝，感谢所有维护者的努力）。

我知道一般来说输入

pipe

存在问题（它可能需要更高种类的类型），但除此之外，我正在努力满足这里的检查器。

这是一个失败的原因吗？

import { camel, isArray, isObject } from 'radash';
import { T, cond, fromPairs, head, identity, juxt, last, map, o, pipe, toPairs, useWith } from 'ramda';

const camelArray: <A>(arr: A[]) => A[] = map((arr) => camelKeys(arr));

// No overload matches this call.
// The last overload gave the following error.
// Argument of type '(fn: (x: unknown) => unknown, list: readonly unknown[]) => unknown' is not assignable to parameter of type '(args_0: (x: unknown) => unknown) => unknown'.
// Target signature provides too few arguments. Expected 2 or more, but got 1.
const mapKeysAndValues = useWith(pipe(map, fromPairs), [identity, toPairs]);

// Expected 7 arguments, but got 1.
const camelObj = mapKeysAndValues(
    juxt([
        o(camel, head),
        o((x) => camelKeys(x), last),
    ]),
);

// No overload matches this call.
// The last overload gave the following error.
// Type 'unknown' is not assignable to type '(value: any) => unknown'.
const camelKeys = cond([
    [isArray, camelArray],
    [isObject, camelObj],  // The above error is actually emitted at camelOj here.
    [T, identity],
]);

export { camelKeys };

不确定您想要对此进行多少ramdify，很抱歉，如果我的回答对这个问题的具体问题没有帮助，请提供指向打字稿游乐场的链接，以防您需要具体帮助。

这最终有助于将对象属性驼峰化， 因为这似乎是您的预期结果。请提供

given

与

expected

，以防情况并非如此。

const { camel } = window.radash;

const camellizeObject = R.pipe(
  R.toPairs,
  R.map(([key, val]) => [camel(key), val]),
  R.fromPairs,
);

const camellize = (input /* obj | array */) => R.map(
  camellizeObject,
  // the [].concat(input) could help you save that cond
  ([] /* as Record<string, unknown>[] */).concat(input),
);


console.log(
  camellize({ snaked_name: 'Giuseppe', snaked_surname: 'Mandato' }),
)
