title: FreeSewing in the browser
---
Thanks to the advances in browser standardisation around JavaScript
ESM modules, not to mention [the new Skypack CDN](https://www.skypack.dev/),
you can generate patterns in the browser with a few lines of JavaScript.
:::tip
##### Use FreeSewing.org if you just want a pattern
These instructions are intended for people who want to generate
their own patterns using FreeSewing packages.
If you _just want a sewing pattern created for you,_
you can get all our designs on [FreeSewing.org](https://freesewing.org/),
our website for makers.
:::
## High level overview
To generate a pattern, you will need to:
- Instantiate the pattern (`new ...`)
- Pass it the settings and measurements you want to use (`{ ... }`)
- Load the theme plugin (using `use()`)
- Draft the pattern (using `draft()`)
- Render it to SVG (using `render()`)
Which can be done as a one-liner since `use()`, `draft()` and
`render()` are all chainable, as shown below.
## Code example
Below is a complete example.
```html
<html>
<head>
<!-- This entire head tag is optional/cosmetic -->
<title>FreeSewing browser example</title>
<style>
body {
font-size: 24px;
padding: 1rem;
}
svg {
max-width: calc(100vw - 4rem);
max-height: calc(100vh - 4rem);
margin: 0 auto;
}
#container {
text-align: center;
}
</style>
</head>
<body>
<script type="module">
import { Aaron } from 'https://cdn.skypack.dev/@freesewing/aaron';
import { pluginTheme as theme } from 'https://cdn.skypack.dev/@freesewing/plugin-theme';
const svg = new Aaron({
sa: 10, // Seam allowance
paperless: true, // Enable paperless mode
// More settings, see: https://FreeSewing.dev/reference/settings
measurements: { // Pass in measurements
biceps: 387,
chest: 1105,
hips: 928,
hpsToWaistBack: 502,
neck: 420,
shoulderSlope: 13,
shoulderToShoulder: 481,
waistToHips: 139,
}
})
.use(theme) // Load theme plugin
.draft() // Draft the pattern
.render() // Render to SVG
// Update DOM
document.getElementById("container").innerHTML = svg
</script>
<div id='container'>SVG output will appear here</div>
</body>
</html>
```
## Dependencies
If you compare this example with [our Node.js
example](/howtos/environments/nodejs) you'll notice that you do not
need to worry about loading any dependencies. Not even `@freesewing/core`
is loaded, because Skypack will pull in all dependencies for you.
