Validators

For every AST node, the bredon-types package ships a validator function that simply checks the node type.

The following validators exist:

• isDimension
• isExpression
• isFloat
• isFunctionExpression
• isHexColor
• isIdentifier
• isInteger
• isOperator
• isParenthesis
• isSeparator
• isStringLiteral
• isUrl
• isValue
• isValueList

Each validator function takes a single AST node as first parameter and returns a boolean.

Example

import { isIdentifier, isHexColor } from 'bredon-types'

const ast = {
  type: 'HexColor',
  value: 'FFF'  
}

isIdentifier(ast) // => false
isHexColor(ast) // => true
