Getting started 🚀

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.

The String method

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"

The DataURIParser method

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"
