Generate Converters & Helpers

• @deriving(accessors)
• @deriving(jsConverter)
• @deriving({jsConverter: newType})
• @deriving(abstract)
  • @optional
  • @obj

Use @deriving to

• Automatically generate functions that convert between ReScript's internal and JS runtime values (e.g. variants).
• Convert a record type into an abstract type with generated creation, accessor and method functions.
• Generate some other helper functions, such as functions from record attribute names.
