# Global installation
npm install -g tinyhtml
# Project-specific installation
npm install tinyhtml
Or for local development:
npm install --save-dev tinyhtml
TinyHTML uses a structured approach with separate folders for source and output:
my-project/
├── tinyhtml-views/ # Your .tml source files
│ ├── index.tml
│ ├── about.tml
│ └── ...
├── views/ # Compiled HTML files
│ ├── index.html
│ ├── about.html
│ └── ...
└── package.json
tinyhtml init
# Compile all .tml files from tinyhtml-views/ to views/
tinyhtml compile
# Or use npm scripts
npm run build
# Watch for changes
npm run watch
div: "Hello World"
↓ compiles to →
<div>Hello World</div>
div.container.main#content: "Content"
↓ compiles to →
<div class="container main" id="content">Content</div>
input[type="text"][name="username"][required]
↓ compiles to →
<input type="text" name="username" required>
html[lang="en"]:
head:
title: "My Page"
body:
h1: "Welcome"
p: "This is a paragraph."
↓ compiles to →
<html lang="en">
<head>
<title>My Page</title>
</head>
<body>
<h1>Welcome</h1>
<p>This is a paragraph.</p>
</body>
</html>
div: |
This is line 1
This is line 2
This is line 3
↓ compiles to →
<div>
This is line 1
This is line 2
This is line 3
</div>
!DOCTYPE html
↓ compiles to →
<!DOCTYPE html>
# Initialize new project structure
tinyhtml init
# Compile entire project (tinyhtml-views/ → views/)
tinyhtml compile
# Watch for changes and auto-compile
tinyhtml compile --watch
# Compile a single file
tinyhtml compile input.tml
# Compile with custom output
tinyhtml compile input.tml -o output.html
# Compile directory
tinyhtml compile src/ -o dist/
# Watch directory
tinyhtml compile src/ -o dist/ --watch --recursive
import { TinyHTMLCompiler } from 'tinyhtml';
const compiler = new TinyHTMLCompiler();
// Compile string
const html = compiler.compile('div: "Hello World"');
// Compile file
compiler.compileFile('input.tml', 'output.html');
// Compile entire project
compiler.compileProject('.');
// Compile directory
compiler.compileDirectory('tinyhtml-views/', 'views/', { recursive: true });
Compiles TinyHTML source code to HTML string.
Compiles a .tml file to HTML. If outputPath is not provided, creates a .html file next to the input.
Compiles an entire project using the standard structure (tinyhtml-views/ → views/).
Compiles all .tml files in a directory to the specified output directory.
