graphql 查询的 typescript 类型声明错误答案

【问题标题】：Error at typescript type declaration of graphql querygraphql 查询的 typescript 类型声明错误

【问题描述】：

我正在使用 Nuxt.js (Vuex) + Apollo。

现在，我正在努力让 Typescript 进入这个项目，尤其是围绕 Graphql。我读了这个article 并生成了类型文件，但它不起作用。我无法在存储目录中的.ts 文件中导入查询。

生成的类型文件。 (~/graphql/types.d.ts)

declare module '*/activate.gql' {
  import { DocumentNode } from 'graphql'; <- another problem: ts says "error TS2307: Cannot find module 'graphql'"
  const defaultDocument: DocumentNode;
  

  export default defaultDocument;
}

这是由codegen.yml生成的：

schema: http://localhost:3000/graphql
generates:
  ./graphql/types.d.ts:
    documents: ./graphql/**/*.gql
    plugins:
      - typescript
      - typescript-graphql-files-modules

我无法在商店导入activate 查询。 (~/store/user.ts)

import activate from '~/graphql/mutations/activate.gql'; <- "error TS2307: Cannot find module '~/graphql/mutations/auth/activate.gql'"

根据上面的文档，这将工作......

目录结构在这里。

- graphql
  |- queries
  |- mutations
     |- activate.gql
  |- types.d.ts

- store
  |- user.ts

- codegen.yml

【问题讨论】：

您是否安装了graphql 软件包？也许在您的问题中包含您的package.json。您将需要修复声明中的错误。这可能会解决您遇到的第二个错误。
感谢您的评论。我已经在这个项目中安装了graphql，可以在node_modules中找到graphql packege...

【解决方案1】：

我明白了！！我不确定这个解决方案是不是最好的，但是，通过向global.d.ts 生成查询声明，我可以从任何地方导入查询而不会出错！！

如果你知道更好的解决方案，请告诉我。

codegen.yml:

schema: http://localhost:3000/graphql
generates:
  ./graphql/types.d.ts:
    documents: ./graphql/**/*.gql
    plugins:
      - typescript
  ./global.d.ts:
    documents: ./graphql/**/*.gql
    plugins: 
      - typescript-graphql-files-modules
