Add/Update the following lines into package.json

    "main": "dist/index.js",
    "types": "dist/index.d.ts",
    "files": [
    "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1",
        "build": "tsc",
        "clean": "rm -Rf dist/*",
        "start": "npm run build -- -w",
        "lint:js": "eslint '**/*.js' --ignore-pattern node_modules/",
        "lint:ts": "eslint '**/*.ts' --ignore-pattern node_modules/"

Replace content in tsconfig.json

    "compilerOptions": {
        /* Basic Options */
        "target": "es6",
        "module": "commonjs",
        "declaration": true,
        "sourceMap": true,
        "outDir": "dist",
        "rootDir": "src",

        /* Strict Type-Checking Options */
        "strict": true,

        /* Additional Checks */
        "noImplicitReturns": true,
        "noFallthroughCasesInSwitch": true,

        /* Module Resolution Options */
        "esModuleInterop": true,

        /* Advanced Options */
        "forceConsistentCasingInFileNames": true
    "include": ["src"],
    "exclude": ["node_modules"]

Replace content in .eslintrc.json

    "env": {
        "commonjs": true,
        "es6": true,
        "node": true
    "extends": ["airbnb-base", "prettier"],
    "parser": "@typescript-eslint/parser",
    "parserOptions": {
        "ecmaVersion": 6
    "plugins": ["prettier", "@typescript-eslint"],
    "rules": {
        "indent": ["error", 4],
        "no-console": "off",
        "prettier/prettier": ["error"]

Note: Using console.log to be an issue for production code. The best solution is to replace uses of console.log with a logging framework such as winston. For now, add the rules: "no-console": "off" to suppress the error.
