fastContentTypeParse.safeParse(string)

const contentType = fastContentTypeParse.safeParse('application/json; charset=utf-8')

  • parameters: An object of the parameters in the media type (name of parameter always lower case). Example: {charset: 'utf-8'}

In case the header is invalid, it will return an object with an empty string '' as type and an empty Object for parameters.
