up.script up.script.config

Configuration object

An array of CSS selectors matching default assets.

By default, all remote scripts and stylesheets in the <head> are considered assets. Inline scripts and internal styles are not tracked by default, but you can include them with an [up-asset] attribute.

Unpoly only tracks assets in the <head>. Elements in the <body> are never tracked, even if they match one of the configured selectors.

See Tracking assets for examples.

Exceptions to up.script.config.assetSelectors.

Matching elements will not be considered assets, even if they match up.script.config.assetSelectors.

An array of CSS selectors matching elements that run JavaScript.

By default, this matches all <script> elements with a JavaScript type.

This configuration does not affect what Unpoly considers assets. For this, configure up.script.config.assetSelectors.

Exceptions to up.script.config.scriptSelectors.

Whether Unpoly will run callbacks in HTML attributes like [up-on-loaded].

Whether Unpoly will run <script> elements in new fragments.

A CSP script nonce for the initial page that booted Unpoly.

The nonce lets Unpoly run JavaScript in HTML attributes like [up-on-loaded] or [up-on-accepted]. See Restricting callbacks with nonces.

The nonce can either be configured as a string or as a function that returns the nonce.

Defaults to the content attribute of a <meta> tag named csp-nonce:

<meta name='csp-nonce' content='secret4367243'>

Whether Unpoly will print a warning when it observes a potentially unsafe Content-Security-Policy header.
