Assets are files that can be served by an HTTP web server without any backend/server processing. They are usually Javascript files, stylesheets (CSS), documents (HTML, pdf, doc), fonts, or media (audio, video) files.

Assets directory

The directory for assets is: marketplace_builder/assets

In order to correctly communicate with the platformOS engine and API, your codebase should be organized into a specific directory structure. The root directory of your project should contain the marketplace_builder directory, and assets should be placed into the assets directory inside marketplace_builder.

Although only the assets directory is required and you can put your assets there, we recommend you further organize your assets into subdirectories inside the assets directory, e.g. images, scripts for Javascript files, styles for CSS files, etc. This is also how the marketplace-kit init command will create the codebase.

Content Delivery Network

Assets are uploaded to a Content Delivery Network (CDN). The directory structure on the CDN corresponds to the required directory structure of your codebase, except for the beginning of the URL.


Location of image asset in codebase:

URL of image asset on CDN:


CDN host and Instance ID are dynamic and will be specific to your instance and region

Accessing assets

You can access assets through their relative path on the CDN, or with the asset_url filter.


Accessing an image from a CSS file located at assets/styles/page.css:

background: transparent url('../images/logo.svg') top center no-repeat;

Accessing a Javascript file from a layout:

<script src="{{ 'scripts/app.js' | asset_url }}"></script>

Accessing a CSS file from a layout:

<link rel="stylesheet" href="{{ 'styles/app.css' | asset_url }}">

Accessing an HTML file from a page:

<a href="{{ 'test.html' | asset_url }}">Test</a>

Syncing and deploying assets

Syncing only adds files on the CDN, and all the added assets will stay in the database even if you delete them on your computer.
To remove files from the database that you deleted on your computer, use deploy. See Deploying and Syncing Changes.
