要求语句不是导入语句的一部分.eslint@typescript-eslint/no-var-需要从存储中导入打字稿 [英] Require statement not part of import statement.eslint@typescript-eslint/no-var-requires importing typescript from storage

问题描述

我必须从 Firebase 存储桶中导入一个打字稿文件.它包含数据和类型定义.

I have to import a typescript file from the Firebase storage bucket. It contains data as well as type definitions.

export interface MyData {
 // ...
}

export const myData = {
 // ...
}

这是我附带的代码:

export const readData = async (fileDir: string, fileName: string): Promise<object> => {
  // Open the bucket
  const bucket: Bucket = admin.storage().bucket()
  // Define the file path in the bucket
  const filePath: string = path.join(fileDir, fileName)
  // Define the local file path on the cloud function's server
  const tempFilePath: string = path.join(os.tmpdir(), fileName)
  // Download the file from the bucket
  try {
    await bucket.file(filePath).download({ destination: tempFilePath })
  } catch (error) {
    functions.logger.error(error, { structuredData: true })
  }
  // Extract the needed variable export from the file
  const data = require(tempFilePath)
  // provide the variable
  return data
}

eslint 抱怨:

require 语句不属于 import statement.eslint@typescript-eslint/no-var-requires

Require statement not part of import statement.eslint@typescript-eslint/no-var-requires

开启:

const data = require(tempFilePath)

导入文件的正确方法是什么?

What would be the right way to import the file?

谢谢

推荐答案

eslint报错信息中包含错误码typescript-eslint/no-var-requires".对该字符串进行网络搜索会出现 文档:

The eslint error message contains the error code "typescript-eslint/no-var-requires". Doing a web search for that string comes up with the documentation:

除了 import 语句外，不允许使用 require 语句(无变量要求)

Disallows the use of require statements except in import statements (no-var-requires)

换句话说，var foo = require(foo") 等形式的使用是禁止.而是使用 ES6 样式导入或 import foo = require("foo")进口.

In other words, the use of forms such as var foo = require("foo") are banned. Instead use ES6 style imports or import foo = require("foo") imports.

您将不得不放松您的 eslint 规则以避免出现此消息(不推荐)，或者接受它的建议并更改代码的语法以使用 import.

You will have to either relax your eslint rules to avoid this message (not recommended), or accept its suggestion and change the syntax of your code to use import.

如果您使用的是 TypeScript，则应阅读 动态导入 可用于 import() 函数.

If you're using TypeScript, you should read the documentation for dynamic imports available with the import() function.
