A pure Swift parser for Data URIs.

Update your Package.swift file.

.package(url: "https://github.com/nodes-vapor/data-uri.git", from: "2.0.0")

There are two options for decoding a Data URI. The first is using the String extension and the second is by using the DataURIParser directly.

This method is by far the easiest to use. All you need to do is call .dataURIDecoded() throws -> (data: Bytes, type: String) on any Data URI encoded String.

import Core //just for `Bytes.string`
import DataURI

let uri = "data:,Hello%2C%20World!"
let (data, type) = try uri.dataURIDecoded()
print(data.string) // "Hello, World!"
print(type) // "text/plain;charset=US-ASCII"

Using the parser is a bit more involved as it returns all of its results as Bytes.

import Core //just for `Bytes.string`
import DataURI

let uri = "data:text/html,%3Ch1%3EHello%2C%20World!%3C%2Fh1%3E"
let (data, type, metadata) = try DataURIParser.parse(uri: uri)
print(data.string) // "<h1>Hello, World!</h1>"
print(type.string) // "text/html"
print(metadata == nil) // "true"
