Welcome to your quick guide on how to harness the power of the hastscript utility for creating syntax trees effortlessly. Think of this utility as a magic wand for your HTML and SVG creations, making the otherwise tedious process much more streamlined and less repetitive.

What is hastscript?

This package functions as a hyperscript interface similar to methods from React and Vue. It allows you to create hast trees with simple and intuitive function calls, making coding a breeze.

When Should I Use hastscript?

You should consider using the hastscript utility in your projects if you’re generating hast syntax trees through code. It dramatically minimizes the repetitive nature of tree creation while ensuring the attributes you pass comply with the necessary format required by hast.

Installation

Here’s how to install hastscript based on your environment:

• In Node.js (version 16+), you can easily install it using npm:

  npm install hastscript

• In Deno, leverage the following import:

  import h from https://esm.sh/hastscript@9

• In browsers, use:

  <script type="module"> import h from https://esm.sh/hastscript@9?bundle </script>

Using hastscript

Here’s how you can use hastscript in your code:

import h, s from 'hastscript';

console.log(
  h('.foo#some-id', [
    h('span', 'some text'),
    h('input', { type: 'text', value: 'foo' }),
    h('a.alpha', { class: ['bravo', 'charlie'], download: true }, [
      'delta',
      'echo'
    ])
  ])
);

console.log(
  s('svg', { xmlns: 'http://www.w3.org/2000/svg', viewBox: '0 0 500 500' }, [
    s('title', 'SVG circle element'),
    s('circle', { cx: 120, cy: 120, r: 100 })
  ])
);

In short, you can think of hastscript as a construction game where you’re building elements instead of blocks. Each function call works like placing a new block in just the right spot, allowing you to create complex structures rapidly.

API Overview

hastscript exports two main functions:

• h(selector[, properties][, …children]) – This creates virtual hast trees for HTML.
• s(selector[, properties][, …children]) – This function creates virtual hast trees for SVG.

Simplifying Syntax Trees

The created syntax tree will follow the structure needed for the hast, with properties specified. This methodology ensures a clean and efficient way to generate HTML/SVG elements.

JSX Compatibility

You can also use hastscript with JSX. Just ensure that the environment is set to support automatic JSX runtime with hastscript or hastscriptsvg.

Types and Compatibility

This package seamlessly integrates with TypeScript, providing additional types for parameters and return values that add to the robustness and reliability of your code.

Security Considerations

While leveraging hastscript, it’s crucial to be aware of potential security risks like Cross-Site Scripting (XSS). Make sure that user-provided input is sanitized. You can achieve this by using hast-util-sanitize to mitigate these risks effectively.

Troubleshooting

• If you encounter issues during installation, ensure that you are using Node.js version 16 or higher.
• If things don’t appear as expected, double-check your function calls, syntax, and ensure that all properties are correctly formatted.
