TypeScript中如何使用webpack的require.context

1.ts中如何使用webpack的require.context

参考:https://github.com/DefinitelyTyped/DefinitelyTyped/issues/6170#issuecomment-331650124node

步骤:

  • 1.安装@types/webpack-env
  • 2.配置tsconfig.json
{
    "compilerOptions": {
        ...
        "types": [
            "node",
            "webpack-env"
        ]
    },
    ...
}

动态引入模块的ts代码

import React from 'react';

interface Context {
  [x: string]: any;
};

const context: Context = {};

const req = require.context('.', true, /Store$/);
req.keys().forEach(key => {
  const keyMatches = key.match(/(a-zA-Z0-9.*)$/);
  if (keyMatches && keyMatches[1]) {
    const name = keyMatches[1];
    const Store = req(key).default;
    context[name] = new Store();
  }
});

export const storesContext = React.createContext(context);

上面的作法已通过时react

新的解决方法
