resolveJsonModule not functioning with Angular 10?

问题

I have a basic JSON file in my assets folder of a brand new Angular 10 project.
Angular CLI: 10.0.1 Node: 14.5.0 OS: win32 x64 TSC version 3.9.5. In my tsconfig.json I have

  "compilerOptions": {
    "module": "commonjs",
    "resolveJsonModule": true,
    "esModuleInterop": true
  }

I have restarted vscode multiple times, and tried compiling from the vscode terminal, a powershell window, and a bash terminal, all returning the same message: "Consider using '--resolveJsonModule' to import module with '.json' extension". I have tried compiling with multiple combinations of different options. At this point I'm wondering if I should restart this project and simply downgrade my version of Angular?

回答1:

In Angular version 10 we have 3 "tsconfig" files.

You have to add "resolveJsonModule" and "esModuleInterop" options in the "tsconfig.app.json" file inside the "compilerOptions".

The file should look like this:

{
  "extends": "./tsconfig.base.json",
  "compilerOptions": {
    "resolveJsonModule": true,
    "esModuleInterop": true,
    "outDir": "./out-tsc/app",
    "types": []
  },
  "files": [
    "src/main.ts",
    "src/polyfills.ts"
  ],
  "include": [
    "src/**/*.d.ts"
  ]
}
