如何（我可以）在 React+JS 中使用 react-financial-charts 库

Question

react-financial-charts 库是用 TS 编写的。我正在尝试在我的 (React+Js) 项目中使用它，因为它有积极的贡献。但是文档不存在，Q&A on Github 根本没有帮助。它主要讨论基于 TS 的解决方案，我不知道 TypeScript。我的问题很基本，

1. 首先是否可以在 React+JS 项目中使用用 TS 编写的 npm 库？
2. 如果是，那怎么办？

到目前为止我已经尝试过：

• 我检查了tslib 包在node_modules 目录中
• 我在 Github 问答部分搜索了一些关于如何在 React+JS 中实现的指导
• 我解析了 react-financial-charts 和 @react-financial-charts 的 npm 包，以对某些模块进行命名导入，以查看是否可以导入图表组件，但没有成功，导致模块未找到错误

Module not found: Can't resolve '@react-financial-charts' in '/Users/****/***/***/***/root-app-folder/src/pages'

• 我尝试导入和使用 tsx、tsv 和 ts 文件，并且按照他们 github 页面上的 discussion 应该能够

当我输入问题时，我找到了解决方案，它是我实现的“cerchio-pixel”共享沙箱，它在我的项目中运行。

下面是实现财务图表的 React 组件以供快速参考：

export default Stonk;

其中data.js文件如下：

export let initialData = [

    close: 135.0087,
    volume: 73591581
  },
  {
    date: "2021-02-02 15:45:00",
    open: 134.9707,
    low: 134.9307,
    high: 134.9707,
    close: 134.9307,
    volume: 67639193
  },
  {
    date: "2021-02-02 15:30:00",
    open: 134.6608,
    low: 134.6608,
    high: 134.975,
    close: 134.975,
    volume: 64815258
  },
  {
    date: "2021-02-02 15:15:00",
    open: 134.8585,
    low: 134.6237,
    high: 134.9716,

我添加了上面的文件并将组件导入到我的项目的其他地方，它按预期工作。我可能遗漏了一些非常明显的内容和/或没有足够的文档来阅读有关如何实现该库的信息，但希望这可以帮助其他找不到有关如何实现它的足够资源并正在搜索问答的人，现在他们'会有一个 StackOverflow 搜索结果。祝黑客愉快！
