ExpressionSchema

const ExpressionSchema: z.ZodType<any[]>

Defined in: packages/core/src/schemas/base.schema.ts:224

MapLibre expression for data-driven styling.

Remarks

MapLibre expressions provide powerful data-driven styling capabilities. An expression is an array where the first element is the operator name.

Common Operators:

• get - Get feature property
• interpolate - Interpolate between values
• match - Match values
• case - Conditional logic
• step - Step function

This schema provides basic validation (array starting with string). Full expression syntax is validated by MapLibre at runtime.

Examples

Get Property

text-field: ["get", "name"]

Interpolate by Zoom

circle-radius:
  - interpolate
  - ["linear"]
  - ["zoom"]
  - 5
  - 2
  - 15
  - 10

Match Values

circle-color:
  - match
  - ["get", "type"]
  - "park"
  - "#228B22"
  - "water"
  - "#4169E1"
  - "#808080"
