GitHub - wooorm/mdxjs-rs: Compile MDX to JavaScript in Rust (original) (raw)

mdxjs-rs

Compile MDX to JavaScript in Rust.

When should I use this?

You can use this crate when you’re dealing with the Rust language and want to compile MDX to JavaScript. To parse the MDX format to a syntax tree, use markdown-rs instead.

This project does not yet support plugins. To benefit from the unified (remark and rehype) ecosystem, use@mdx-js/mdx.

What is this?

This Rust crate works exactly like the npm package @mdx-js/mdx. It uses the Rust crates markdown-rs and SWC to deal with the markdown and JavaScript inside MDX.

Install

With Rust (rust edition 2018+, ±version 1.56+), install with cargo:

Use

extern crate mdxjs;

fn main() -> Result<(), markdown::message::Message> { println!( "{}", mdxjs::compile( r###" import {Chart} from './snowfall.js' export const year = 2018

Last year’s snowfall

In {year}, the snowfall was above average. It was followed by a warm spring which caused flood conditions in many of the nearby rivers.

Ok(())

}

Yields (prettified):

import {Fragment as _Fragment, jsx as _jsx, jsxs as _jsxs} from 'react/jsx-runtime' import {Chart} from './snowfall.js' export const year = 2018

function _createMdxContent(props) { const _components = Object.assign({h1: 'h1', p: 'p'}, props.components) return _jsxs(_Fragment, { children: [ _jsx(_components.h1, {children: 'Last year’s snowfall'}), '\n', _jsxs(_components.p, { children: [ 'In ', year, ', the snowfall was above average.\nIt was followed by a warm spring which caused\nflood conditions in many of the nearby rivers.' ] }), '\n', _jsx(Chart, {year: year, color: '#fcb32c'}) ] }) }

function MDXContent(props = {}) { const {wrapper: MDXLayout} = props.components || {} return MDXLayout ? _jsx(MDXLayout, Object.assign({}, props, {children: _jsx(_createMdxContent, props)})) : _createMdxContent(props) }

export default MDXContent

API

mdxjs-rs exposescompile,JsxRuntime,Options, and a few other structs and enums.

See the crate docs for more info.

Project

Test

mdxjs-rs is tested with a lot of tests. These tests reach all branches in the code, which means that this project has 100% code coverage.

The following bash scripts are useful when working on this project:

• run examples:
  RUST_BACKTRACE=1 cargo run --example lib
• format:
• lint:
  cargo fmt --check && cargo clippy --all-targets
• test:
  RUST_BACKTRACE=1 cargo test
• docs:
  cargo doc --document-private-items

Version

mdxjs-rs follows SemVer.

Security

MDX is a programming language. It is JavaScript. It is not safe to let people you don’t trust write MDX.
