Here's the eslint.config.js from a similar TypeScript project of mine, might need some adjustments though.

const globals = require("globals");
const tsEslint = require('typescript-eslint');
const tsEslintPlugin = require('@typescript-eslint/eslint-plugin');
const tsEslintParser = require('@typescript-eslint/parser');
const prettierEslint = require('eslint-config-prettier');
const jest = require('eslint-plugin-jest');

module.exports = tsEslint.config(
  {
    files: ["src/**/*.ts"],
  },
  {
    ignores: [
      "dist/",
      "**/*.js",
      "**/*.cjs",
      "**/*.mjs",
      "**/*.d.ts"
    ]
  },
  ...tsEslint.configs.strictTypeChecked,
  {
    languageOptions: {
      parser: tsEslintParser,
      parserOptions: {
        project: 'tsconfig.json',
        tsconfigRootDir: __dirname,
        sourceType: 'module',
      },
      globals: {
        ...globals.node,
        ...globals.jest,
      },
    },
    plugins: {
      '@typescript-eslint': tsEslintPlugin,
    },
    rules: {

        'warn',

          custom: {
            regex: '^I[A-Z]',
            match: true,
          },
        },
        {
          selector: ['variableLike', 'function'],
          format: ['camelCase'],
          leadingUnderscore: 'allow',

      ],
