Condition class final

A conditional expression that can be evaluated at runtime.

Conditions are used to make dynamic decisions in the application based on the current state or user input. They can be used for:

• Navigation guards
• Content visibility
• Feature flags
• A/B testing

Example CMS schema:

export const condition = defineType({
  name: 'condition',
  fields: [
    {
      name: 'configuration',
      type: 'reference',
      to: [{type: 'condition.config'}],
    },
  ],
});

Evaluated values select a matching conditional case, such as a platform name or a boolean string. Null means no value was produced.
