How to get ESLint result from TypeScript AST using @typescript-eslint/typescript-estree

main.ts

import * as ts from "typescript";
import { SourceCode, Linter, AST } from "eslint";
import { Extra } from "@typescript-eslint/typescript-estree/dist/parser-options";
import convert from "@typescript-eslint/typescript-estree/dist/ast-converter";

function initExtra() {
  return {
    tokens: null,
    range: false,
    loc: false,
    comment: false,
    comments: [],
    strict: false,
    jsx: false,
    useJSXTextNode: false,
    log: console.log,
    projects: [],
    errorOnUnknownASTType: false,
    errorOnTypeScriptSyntacticAndSemanticIssues: false,
    code: "",
    tsconfigRootDir: process.cwd(),
    extraFileExtensions: [],
    preserveNodeMaps: undefined,
  } as Extra;
}

function getEslintMessageFromTypeScriptAST(tsSourceCode: ts.SourceFile) {

  const code = tsSourceCode.getFullText();

  // Create options for converter
  const extra = initExtra();

  // They're needed to pass the converter result to eslint's SourceCode
  extra.tokens = [];
  extra.comment = true;
  extra.comments = [];
  extra.code = code;

  // Convert from TypeScript AST to estree AST
  const { estree } = convert(tsSourceCode, extra, false);

  // Verfy using ESLint linter
  const linter = new Linter();
  return linter.verify(
    new SourceCode(code, estree as AST.Program),
    {
      rules: {
        semi: 2,
      },
    },
    {
      filename: "test.ts",
    },
  );
}

const content = `
  // missing semicolon
  const hoge = 1
`;
const tsSourceCode = ts.createSourceFile("test.ts", content, ts.ScriptTarget.Latest, true);

const eslintResult = getEslintMessageFromTypeScriptAST(tsSourceCode);
eslintResult.forEach(({ message }) => console.log(message));
