Partytown is a lazy-loaded library to help relocate resource intensive scripts into a web worker, and off of the main thread.
If you're using third-party scripts for things like analytics or ads, Partytown is a great way to make sure that they don't slow down your site.
The Astro Partytown integration installs Partytown for you and makes sure it's enabled on all of your pages.
The astro add
command-line tool automates the installation for you. Run one of the following commands in a new terminal window. (If you aren't sure which package manager you're using, run the first command.) Then, follow the prompts, and type "y" in the terminal (meaning "yes") for each one.
# Using NPM
npx astro add partytown
# Using Yarn
yarn astro add partytown
# Using PNPM
pnpm astro add partytown
If you run into any issues, feel free to report them to us on GitHub and try the manual installation steps below.
First, install the @astrojs/partytown
package using your package manager. If you're using npm or aren't sure, run this in the terminal:
npm install @astrojs/partytown
Then, apply this integration to your astro.config.*
file using the integrations
property:
// astro.config.mjs
import { defineConfig } from 'astro/config';
+ import partytown from '@astrojs/partytown';
export default defineConfig({
// ...
integrations: [partytown()],
// ^^^^^^^^^^^
});
Partytown should be ready to go with zero config. If you have an existing 3rd party script on your site, try adding the type="text/partytown"
attribute:
- <script src="fancy-analytics.js"></script>
+ <script type="text/partytown" src="fancy-analytics.js"></script>
If you open the "Network" tab from your browser's dev tools, you should see the partytown
proxy intercepting this request.
To configure this integration, pass a 'config' object to the partytown()
function call in astro.config.mjs
.
// astro.config.mjs
// ...
export default defineConfig({
integrations: [
partytown({
config: {
// options go here
},
}),
],
});
This mirrors the Partytown config object.
Partytown ships with a debug
mode; enable or disable it by passing true
or false
to config.debug
. If debug
mode is enabled, it will output detailed logs to the browser console.
If this option isn't set, debug
mode will be on by default in dev or preview mode.
// astro.config.mjs
export default defineConfig({
integrations: [
partytown({
// Example: Disable debug mode.
config: { debug: false },
}),
],
});
Third-party scripts typically add variables to the window
object so that you can communicate with them throughout your site. But when a script is loaded in a web-worker, it doesn't have access to that global window
object.
To solve this, Partytown can "patch" variables to the global window object and forward them to the appropriate script.
You can specify which variables to forward with the config.forward
option. Read more in Partytown's documentation.
// astro.config.mjs
export default defineConfig({
integrations: [
partytown({
// Example: Add dataLayer.push as a forwarding-event.
config: {
forward: ['dataLayer.push'],
},
}),
],
});

Failed to fetch
error, make sure you're not using any browser extensions that are blocking the script.
