Elm 0.19 moved encodeUri and decodeUri to the elm/url package, and renamed them percentEncode and percentDecode.

encodeUri : String -> String

Use this to escape query parameters. Converts characters like / to %2F so that it does not clash with normal URL

It work just like encodeURIComponent in JavaScript.

encodeUri "hat" --> "hat"


encodeUri "to be" --> "to%20be"


encodeUri "99%" --> "99%25"

decodeUri : String -> Maybe String

Use this to unescape query parameters. It converts things like %2F to /. It can fail in some cases. For example, there is no way to unescape % because it could never appear alone in a properly escaped string.

It works just like decodeURIComponent in JavaScript.

-- ASCII
decodeUri "hat"     --> Just "hat"


decodeUri "to%20be"   --> Just "to be"


decodeUri "99%25"       --> Just "99%"


-- UTF-8
decodeUri "%24"       --> Just "$"


decodeUri "%C2%A2"    --> Just "¢"


decodeUri "%E2%82%AC" --> Just "€"


-- Failing
decodeUri "%"   --> Nothing  -- not followed by two hex digits


decodeUri "%XY" --> Nothing  -- not followed by two HEX digits


decodeUri "%C2" --> Nothing  -- half of the "¢" encoding "%C2%A2"
