apollo-server-express、apollo-server 和 apollo-cache-control 中的 TypeScript 导入问题

Question

I'm trying to update from " apollo-server": "^2.9.4" and "apollo-server-express" : "^2.9.4" to 2.12.0 version in Typescript, During the build process of the app I get the following error:

node_modules/apollo-server-express/node_modules/apollo-server-core/dist/plugin/index.d.ts:1:13

error TS1005: '=' expected.

1 import type { ApolloServerPlugin } from 'apollo-server-plugin-base';

I have not found the fix for this yet, I've deleted node_modules folder and package-lock.json but still not working.

It would be nice to have some help....

tsconfig.json


{
  "compilerOptions": {
    "target": "es5",
    "moduleResolution": "node",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,

    "declaration": true
  },
  "include": [
    "src/**/*"
  ],
  "exclude": [
    "node_modules",
    "**/*.spec.ts",
    "**/*.test.ts"

  ]

}

Answer 1

The import type syntax used in apollo-server-core isn't supported by the version of typescript that you're using (v3.6). This syntax became available from v3.8 onwards. https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export

Update typescript and the error will disappear

Answer 2

I was also facing same kind of error in typescript imports, I tried different values in lib , modules and target in tsconfig.json file but none of them worked, I never wanted to change the node_modules file but in the end I had to (sad smiley), change I made in my index.d.ts file was
import type { DocumentNode } from 'graphql/language/ast';
to
import { DocumentNode } from 'graphql/language/ast';
also this value in lib in tsconfig.json also helped
"lib": ["es6", "dom", "esnext", "esnext.asynciterable"],
