Problem
TypeScript users get type errors when using
DataTypes.VECTOR(),DataTypes.HALFVEC(),or
DataTypes.SPARSEVEC()because the type definitions don't augment Sequelize's DataTypes.Error:
Property 'VECTOR' does not exist on type 'typeof DataTypes'Solution
Added module augmentation in
types/sequelize/index.d.tsto extend Sequelize'sDataTypesnamespace with the vector types.Changes
VectorDataTypeConstructor,HalfvecDataTypeConstructor,SparsevecDataTypeConstructorinterfacessequelizeto declare the types onDataTypesnamespaceDataTypes.VECTOR(3)andDataTypes.postgres.VECTOR(3)
