Starting a new JS app? Build, test and run advanced apps with kyt 🔥

kyt

Every sizable JavaScript web app needs a common foundation: a setup to build, run, test and lint your code. kyt is a toolkit that encapsulates and manages the configuration for web apps.

Read more about kyt in our blog post.

Quick Start

1. Install Node.js (v14.0+ required). On Mac, this is as simple as:

brew install nvm
nvm use

1. yarn add kyt
2. yarn kyt setup - This will set up your project with application and configuration files so that you can get started with kyt. Learn more about setup.
3. yarn dev
4. Check out http://localhost:3000

Features

• Isomorphic rendering of JavaScript apps
• Client and server hot-reloading in dev
• Babel presets for general ES6 support and React
• ESLint configuration and custom rules
• Jest presets for running unit tests and CSS-in-JS linting
• Optional client-only and server-only modes
• Ability to override Webpack configuration from kyt.config.js

How it Works

kyt manages configuration for all aspects of development. It can be installed as a dependency into a new or existing project. kyt’s goal is to encapsulate only development tools, giving users the freedom to control their source directory and make important decisions about app architecture. kyt provides a command line interface for running all development tools.

Developers design their own architecture, choosing the tools they need for rendering, styling, and handling data.

For advanced use cases, kyt enables developers to add additional tools and configuration. See our config override instructions for details, and our recipes for examples.

Setting up a kyt project

kyt setup is a utility for bootstrapping kyt projects and installing starter-kyts. It can be run to create a new project or integrate kyt with an existing project.

See the kyt documentation for more details.

Command line

kyt includes a command line program with all the commands needed for development.

Running kyt setup includes these commands as scripts in your package.json:

yarn dev

Or you can run a command using yarn kyt {command}:

yarn kyt build

Here are the available commands:

• dev starts a development environment
• build compiles server and client code for production use
• help shows commands and their documentation

See our CLI docs for further details.

Conventions

kyt follows a few simple conventions.

All projects must have the following structure:

src/
  client/
    index.js
    polyfills.js
  server/
    index.js
    polyfills.js

Each index.js file acts as the build entry.

(Note that server/index.js is not required if hasServer is false in config). (Note that client/index.js is not required if hasClient is false in config).

If you're setting up a new project see our full list of conventions.

Configuration

kyt allows you to specify options in a kyt.config.js file. See the kyt config docs for instructions.

kyt uses Webpack to compile src code. See our recipes for extending configuration.

kyt respects Babel config files defined at the root of user projects, and provides presets to provide opinionated configurations. (If no Babel config file is defined in the user project, babel-preset-kyt-core is used when compiling Webpack.)

starter-kyts

While kyt can be easily integrated into new or existing Node projects, it is even more powerful when used with a starter-kyt. A starter-kyt offers the benefits of a boilerplate while minimizing the amount of new tools to learn and maintain.

The kyt setup command installs any preconfigured starter-kyt git repository, adding additional dependencies and building a source directory.
