Headless Websites

Headless architecture is most useful when the website needs capabilities that are difficult to achieve efficiently within a more traditional CMS setup.

That may include:

• complex frontend interactions
• multiple websites or applications using shared content
• content distributed across different channels
• integration with several business systems
• advanced search
• personalisation
• high performance requirements
• independent frontend and backend development
• progressive development across multiple digital products
• greater control over frontend technology

For some organisations, the website is only one part of a broader digital ecosystem. The same content may also need to appear in a customer portal, mobile application, campaign experience or another digital product.

A headless approach can allow that content to be managed centrally while different interfaces consume it in different ways.

For larger organisations, this can also connect with enterprise websites, particularly where the platform needs to integrate with multiple systems or support several digital channels.

The architecture needs to be justified by the requirements. If a conventional CMS can meet the organisation's needs more simply and cost-effectively, that may still be the better choice.

Separating the frontend from the CMS gives development teams more freedom over how the experience is built. Instead of working within the rendering layer of the CMS, the frontend can be developed using modern frameworks and optimised around the needs of the experience.

Bright Labs works with technologies including Nuxt and modern frontend frameworks where they are appropriate to the project.

This can support:

• faster and more responsive interfaces
• richer interactions
• reusable frontend components
• more flexible deployment
• independent frontend development
• tighter control over performance
• integration with API-driven services
• different frontends using the same underlying content

This can be particularly useful where the website behaves more like an application than a traditional content site.

The frontend can still draw content from a CMS such as Craft CMS, but the relationship between the two is more flexible. That flexibility does introduce additional technical considerations. Preview workflows, caching, deployment, search, forms and other functionality may need to be handled differently from a conventional CMS implementation.

These requirements need to be considered during architecture planning rather than discovered during development.

A headless website often makes most sense when content needs to connect with several systems or experiences. The CMS may be one source of information among many, alongside CRM, ERP, product data, commerce platforms, search tools or other APIs.

The frontend can bring these sources together into a single user experience.

Depending on the project, this may involve:

• CRM integration
• ERP data
• product information
• commerce functionality
• Algolia or other search platforms
• customer account data
• marketing automation
• authentication
• third-party APIs
• internal business systems

For organisations considering a broader technology change, headless architecture may form part of a website replatforming project.

Headless is an architectural approach that changes how the CMS, frontend and other systems work together. 

Content modelling also becomes particularly important. Because content may be used in more than one place, it often needs to be structured independently of a specific page layout. This can make content more reusable, but it requires more considered planning around fields, relationships and governance.

Headless architecture can create more technical flexibility, but it can also introduce more moving parts. There may be separate frontend and CMS deployments, APIs between systems, caching layers and additional services responsible for functionality that would traditionally sit inside one platform. This means maintainability needs to be considered from the beginning.

We look at areas such as:

• hosting and infrastructure
• frontend deployment
• CMS hosting
• API performance
• caching
• security
• monitoring
• search
• preview environments
• form handling
• analytics
• error handling
• development workflows
• ongoing support

The content editing experience also matters. A headless build should not make routine publishing unnecessarily difficult for the teams managing the website. Preview, content structure and publishing workflows need to be designed around how editors actually work.

Where an existing CMS is being replaced as part of the project, CMS migration planning may also be required to move content, metadata, URLs and assets safely into the new environment.

A well-planned headless architecture gives organisations greater freedom to evolve the frontend, connect additional systems and reuse content across different experiences without rebuilding the entire platform each time requirements change.
