multipart

Parses multipart/form-data request bodies into typed parts.

Types

pub type Part {
  Field(name: String, value: String)
  Upload(name: String, filename: String, content_type: String, data: BitArray)
}

Functions

parse

pub fn parse(req: Request(BitArray)) -> Result(List(Part), String)

Parse a multipart request body. Returns Error if the Content-Type header is missing, not multipart/form-data, has no boundary, or the body is not valid UTF-8.

Requires the body to already be buffered — use middleware.body_limit upstream.

get_field

pub fn get_field(parts: List(Part), name: String) -> Option(String)

Find the first Field part with the given name. Returns None if not found.

---

uploads

pub fn uploads(parts: List(Part)) -> List(Part)

Filter the parts list to only Upload variants.
