jszz

0.0.0 verified Fri May 01 auth: no javascript

jszz is a simple TypeScript/JSX transpiler designed for lightweight projects. As of version 0.0.0, it is in early development with no stable release or release schedule. It differentiates from established transpilers (like Babel or SWC) by aiming for minimal configuration and a smaller footprint, but lacks production readiness and community support.

Imports

default
wrong
```
const jszz = require('jszz')
```
correct
```
import jszz from 'jszz'
```
ESM-only package; CommonJS require will fail.

transform

wrong

import { transform } from 'jszz/transform'

correct

import { transform } from 'jszz'

transform is a named export, not a subpath module.

compile

wrong

const compile = require('jszz').compile

correct

import { compile } from 'jszz'

ESM-only; require() will not work.

Quickstart

Demonstrates basic usage of the transform function to transpile TypeScript code.

import { transform } from 'jszz';
const code = 'const x: number = 1';
const result = transform(code, { jsx: false });
console.log(result.code);
