typescript引入js或者json配置

根目录下的tsconfig.json添加配置：

"allowJs": true,
"resolveJsonModule": true,

完整配置如下：

{
  "compilerOptions": {
    "module": "commonjs",
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es2017",
    "allowJs": true,
    "resolveJsonModule": true,
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true
  },
  "exclude": ["node_modules", "dist"]
}
