Create React apps with no build configuration, Cli tool for creating react apps. Another tool, kkt-ssr, Is a lightweight framework for static and server-rendered applications.

As of KKT 6.x this repo is "lightly" maintained mostly by the community at this point.


  • The code was rewritten using TypeScript.
  • ♻️ Recompile the code when project files get added, removed or modified.
  • 📚 Readable source code that encourages learning and contribution
  • ⚛️ Override create-react-app webpack configs without ejecting
  • 💝 Expose the configuration file entry and support webpack configuration.
  • 🚀 Supports creat-kkt to create different instances.
  • Jest test runner setup with defaults kkt test


You will need Node.js installed on your system.

npm install kkt

Open in CodeSandbox

Initialize the project from one of the examples, Let's quickly create a react application:

$ npx create-kkt my-app -e uiw
# or npm
$ npm create kkt my-app -e `<Example Name>`
# or yarn 
$ yarn create kkt my-app -e `<Example Name>`

You can download the following examples directly. Download page.

How to rewire your create-react-app project

Create your app using create-react-app and then rewire it.

npm install kkt --save-dev
"dependencies": {
-  "react-scripts": "4.0.1",
"scripts": {
-  "start": "react-scripts start",
+  "start": "kkt start",
-  "build": "react-scripts build",
+  "build": "kkt build",
-  "test": "react-scripts test",
+  "test": "kkt test",
-  "eject": "react-scripts eject"

⚠️ Note: Do NOT flip the call for the eject script. That gets run only once for a project, after which you are given full control over the webpack configuration making kkt no longer required. There are no configuration options to rewire for the eject script.

# Start the Dev Server
$ npm start
# Build your app
$ npm run build


Supports kktrc.js and kktrc.ts.

import express from 'express';
import WebpackDevServer from 'webpack-dev-server';
import { LoaderConfOptions, MockerAPIOptions, DevServerOptions, WebpackConfiguration } from 'kkt';

type KKTRC = {
  proxySetup?: (app: express.Application) => MockerAPIOptions;
  devServer?: (config: WebpackDevServer.Configuration, options: DevServerOptions) => WebpackDevServer.Configuration;
  default?: (conf: WebpackConfiguration, evn: string, options: LoaderConfOptions) => WebpackConfiguration | Promise<WebpackConfiguration>;


import webpack from 'webpack';
import WebpackDevServer from 'webpack-dev-server';
import lessModules from '@kkt/less-modules';
import { LoaderConfOptions, WebpackConfiguration } from 'kkt';

export default (conf: WebpackConfiguration, env: string, options: LoaderConfOptions) => {
  // The Webpack config to use when compiling your react app for development or production.
  // ...add your webpack config
  conf = lessModules(conf, env, options);
  return conf;

 * Modify WebpackDevServer Configuration Example
export const devServer = (config: WebpackDevServer.Configuration) => {
  // Change the https certificate options to match your certificate, using the .env file to
  // set the file paths & passphrase.
  const fs = require('fs');
  config.https = {
    key: fs.readFileSync(process.env.REACT_HTTPS_KEY, 'utf8'),
    cert: fs.readFileSync(process.env.REACT_HTTPS_CERT, 'utf8'),
    ca: fs.readFileSync(process.env.REACT_HTTPS_CA, 'utf8'),
    passphrase: process.env.REACT_HTTPS_PASS
  // Return your customised Webpack Development Server config.
  return config;

// Configuring the Proxy Manually
import express from 'express';
import { createProxyMiddleware } from 'http-proxy-middleware';
import { MockerAPIOptions } from 'kkt';

export const proxySetup = (app: express.Application): MockerAPIOptions => {
  app.use('/api', createProxyMiddleware({
    target: 'http://localhost:5000',
    changeOrigin: true,
   * Mocker API Options
  return {
    path: path.resolve('./mocker/index.js'),
    option: {
      proxy: {
        '/repos/(.*)': '',
      changeHost: true,

The step below is important!

Open your package.json and add a homepage field for your project:
