Kite Chat


Published on webcomponents.org

This project includes 🪁K1te chat client to communicate with the 🪁K1te chat backend.


Install dependencies:

npm i


This sample uses the TypeScript compiler to produce JavaScript that runs in modern browsers. It uses Vite to bundle package. It bundles code with Rollup, pre-configured to output highly optimized static assets for production.

To build the JavaScript version of your driver:

npm run build

The TypeScript compiler is configured to be very strict. You may want to change tsconfig.json to make it less strict.


This project uses @swc/jest for testing. See the jest documentation for more information.

Tests can be run with the test script:

npm test

For local testing during development, the test:watch command will run your tests on every change to your source files:

npm test:watch

Dev Server

This sample uses Vite as build tool. It`s dev server provides rich feature enhancements over native ES modules, for example extremely fast Hot Module Replacement (HMR).

To run the dev server and open the project in a new browser tab:

npm run start

There is a development HTML file located at /index.html that you can view at http://localhost:5173/index.html. Note that this command will serve your code using Lit's development mode (with more verbose errors).


Linting of TypeScript files is provided by ESLint and TypeScript ESLint. In addition, lit-analyzer is used to type-check and lint lit-html templates with the same engine and rules as lit-plugin.

The rules are mostly the recommended rules from each project, but some have been turned off to make LitElement usage easier. The recommended rules are pretty strict, so you may want to relax them by editing .eslintrc.json and tsconfig.json.

To lint the project run:

npm run lint


Prettier is used for code formatting. It has been pre-configured according to the Lit's style. You can change this in .prettierrc.json.

Prettier has not been configured to run when committing files, but this can be added with Husky and and pretty-quick. See the prettier.io site for instructions.

Debug workers

Chrome chrome://inspect/#workers

Firefox about:debugging#/runtime/this-firefox

Driver uses inline module type shared worker for communication with the backend.

Production build bundles worker module and deps to iife so production library created with npm run build is compatible with all modern browsers.



Unfortunately it does not work in Firefox, only works in Chrome. Had to get rid of it.
