JSON schema for the TypeScript compiler's configuration file

Here is a possible JSON schema for the TypeScript compiler's configuration file:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "title": "TypeScript Compiler Configuration",
  "type": "object",
  "properties": {
    "compilerOptions": {
      "type": "object",
      "properties": {
        "allowJs": { "type": "boolean" },
        "checkJs": { "type": "boolean" },
        "noEmit": { "type": "boolean" },
        "noEmitOnError": { "type": "boolean" },
        "strict": { "type": "boolean" },
        "target": {
          "type": ["string", "number"],
          "enum": ["ES3", "ES5", "ES6", "ES2015", "ES2016", "ES2017", "ES2018", "ES2019", "ES2020", "ES2021", "ESNext"]
        },
        "module": {
          "type": ["string", "number"],
          "enum": ["CommonJS", "AMD", "System", "UMD", "ES6", "ES2015", "ES2020", "ESNext"]
        },
        "outFile": { "type": "string" },
        "outDir": { "type": "string" },
        "rootDir": { "type": "string" },
        "baseUrl": { "type": "string" },
        "paths": {
          "type": "object",
          "additionalProperties": { "type": "array", "items": { "type": "string" } }
        },
        "typeRoots": { "type": "array", "items": { "type": "string" } },
        "types": { "type": "array", "items": { "type": "string" } },
        "lib": { "type": "array", "items": { "type": "string" } },
        "experimentalDecorators": { "type": "boolean" },
        "emitDecoratorMetadata": { "type": "boolean" }
      },
      "additionalProperties": false
    },
    "include": { "type": "array", "items": { "type": "string" } },
    "exclude": { "type": "array", "items": { "type": "string" } }
  },
  "required": ["compilerOptions"],
  "additionalProperties": false
}

This schema defines an object with three properties: `compilerOptions`, `include`, and `exclude`. The `compilerOptions` property is itself an object with various properties for configuring the TypeScript compiler, such as `allowJs`, `checkJs`, `noEmit`, `strict`, etc. The other two properties, `include` and `exclude`, are arrays of file patterns to include or exclude from compilation. The schema includes type validations and some additional constraints, such as allowed values for `target` and `module`.
