v1.6.0 – New Docs, Rebuilt Self-Hosting Backend, Better Callbacks, and More

✨ New Features

Better Docs, Better Consent

You did not consent to bad docs. Over the last six months we have been moving incredibly fast, and it felt like the right moment to invest in making sure our documentation lives up to the same standard.

The new site comes with improved navigation, better search, and comprehensive guides for every package and framework. We have also surfaced a lot of hidden features and design details that were easy to miss before.

Rebuilt Self-Hosting Backend

The old backend was showing its age and could be difficult to implement. We have rebuilt the self-hosting backend from the ground up and moved from our own database adapters to FumaDB.

This unlocks support for more databases and ORMs such as TypeORM, Microsoft SQL Server, and MongoDB, with more coming soon.

If you have an existing backend v1 implementation, check out the migration guide.

⚠️ Heads-up: support for the old backend will be removed in the next major release.

Improved Consent Checking

We’ve added a new has() method to the API for checking consent. It is available across all frameworks and supports both simple and complex checks.

// Simple check
const hasAnalytics = has('measurement');
const hasMarketing = has('marketing');

// Complex check
const hasAnalyticsAndMarketing = has({
  and: ['measurement', 'marketing'],
});

const hasEitherAnalyticsOrMarketing = has({
  or: ['measurement', 'marketing'],
});

See the API documentation for full details.

Deprecated: hasConsentFor() and getEffectiveConsents(). These will be removed in the next major release.

Better Callbacks

We’ve overhauled the callback system to make it simpler and faster, while removing unused callbacks.

Current callbacks are:

• onBannerFetched
• onConsentSet
• onError

Performance has also been improved (see issue #369), resulting in better INP scores when using callbacks or GTM.

RTL Support

c15t now supports RTL languages in its prebuilt components, so you can use them in any language.

• Improved formatting and structure
