A tiny library for building parameteried URLs

elm-purl

A tiny library for building parameterized URLs. It is intended to be used with records to give the parameters names and therefore reducing errors.

userUrl : Url { id : Int, show : Bool }
userUrl =
    root |> hash |> s "users" |> int .id |> boolQuery "show" .show

userUrl |> toString { id = 42, show = True }
    --> "/#/users/42?show=true"

Migrating from 2.2.0 to 3.0.0

Version 3.0.0 removed the infix operators (</>, <?>, <#> and @) because they are not allowed in Elm 0.19. Here's how the API has changed:

• First, the module has been renamed from Url to Purl so it won't clash with Elm 0.19's Url module.

• The </> operator is essentially replaced with |>

  root </> s "users" </> int .id
  -- becomes
  root |> s "users" |> int .id

• The <?> operator is |> plus a Query-postfix

  root </> s "users" <?> ("show", bool .show)
  -- becomes
  root |> s "users" |> boolQuery "show" .show

• The <#> and @ operators were just removed; use the hash and toString functions

  root <#> s "users" </> int .id @ { id = 42 }
  -- becomes
  root |> hash |> s "users" |> int .id
      |> toString { id = 42 }
