trait Urls extends PartialInvariantFunctorSyntax

Algebra interface for describing URLs made of a path and a query string.

A path is itself made of segments chained together.

A query string is made of named parameters.

/**
  * Describes an URL starting with a segment containing “articles”, followed
  * by another `String` segment, and a query string containing
  * a mandatory `Lang` parameter named “lang”, and an
  * optional `Int` parameter named “page”.
  *
  * Examples of matching URLs:
  *
  * - /articles/kitchen?lang=fr
  * - /articles/garden?lang=en&page=2
  */
val example = path / "articles" / segment[String]() /? (qs[Lang]("lang") & qs[Option[Int]]("page"))

Type Members

  1. implicit class InvariantFunctorSyntax[A, F[_]] extends AnyRef

    Extension methods for values of type F[A] for which there is an implicit InvariantFunctor[F] instance.

    Extension methods for values of type F[A] for which there is an implicit InvariantFunctor[F] instance.

    Definition Classes
    InvariantFunctorSyntax
  2. implicit class PartialInvariantFunctorSyntax[A, F[_]] extends AnyRef
  3. abstract type Path[A] <: Url[A]

    An URL path carrying an A information

    An URL path carrying an A information

    Values of type Path[A] can be constructed by the operations path, segment, and remainingSegments.

    path / "user" / segment[UUID]("id")
    • Server interpreters raise an error if they can’t parse the incoming request path as a value of type A. By default, they produce a Bad Request (400) response with a list of error messages in a JSON array. Refer to the documentation of your server interpreter to customize this behavior.
    Note

    This type has implicit methods provided by the PathOps, InvariantFunctorSyntax, and the PartialInvariantFunctorSyntax classes.

  4. implicit class PathOps[A] extends AnyRef

    Convenient methods for Paths.

  5. abstract type QueryString[A]

    A query string carrying an A information

    A query string carrying an A information

    QueryString values can be created with the qs operation, and can be combined with the & operation:

    val queryPageAndLang: QueryString[(Int, Option[String])] =
      qs[Int]("page") & qs[Option[String]]("lang")
    • Server interpreters raise an error if they can’t parse the incoming request query string parameters as a value of type A. By default, they produce a Bad Request (400) response with a list of error messages in a JSON array. Refer to the documentation of your server interpreter to customize this behavior.
    Note

    This type has implicit methods provided by the QueryStringSyntax, InvariantFunctorSyntax, and the PartialInvariantFunctorSyntax classes.

  6. abstract type QueryStringParam[A]

    A query string parameter codec for type A.

    A query string parameter codec for type A.

    The trait Urls provides implicit instances of type QueryStringParam[A] for basic types (e.g., Int, String, etc.). You can create additional instances by transforming or refining the existing instances with xmap and xmapPartial.

    Note

    This type has implicit methods provided by the PartialInvariantFunctorSyntax and the InvariantFunctorSyntax classes.

  7. implicit class QueryStringSyntax[A] extends AnyRef

    Extension methods on QueryString.

  8. abstract type Segment[A]

    An URL path segment codec for type A.

    An URL path segment codec for type A.

    The trait Urls provides implicit instances of Segment[A] for basic types (e.g., Int, String, etc.). You can create additional instances by transforming or refining the existing instances with xmap and xmapPartial.

    Note

    This type has implicit methods provided by the PartialInvariantFunctorSyntax and the InvariantFunctorSyntax classes.

  9. abstract type Url[A]

    An URL carrying an A information

    An URL carrying an A information

    Values of type URL[A] are typically constructed by first using the path constructor and then chaining it with segments and query parameters.

    path / "users" / segment[UUID]("id") /? qs[String]("apiKey")
    • Server interpreters raise an error if they can’t parse the incoming request URL as a value of type A. By default, they produce a Bad Request (400) response with a list of error messages in a JSON array. Refer to the documentation of your server interpreter to customize this behavior.
    Note

    This type has implicit methods provided by the PartialInvariantFunctorSyntax and InvariantFunctorSyntax classes.

  10. abstract type WithDefault[A]

    This type is necessary to express different perspectives of servers and clients on optional query string parameters with default value:

    This type is necessary to express different perspectives of servers and clients on optional query string parameters with default value:

    • Client interpreters should define it as Option[A] and omit query string parameters with default value that are empty
    • Server interpreters should define it as A and accept incoming requests whose query string parameters with default value are missing, while providing the defined default value
    • Documentation interpreters should mark the parameter as optional and document the provided default value

    path / "articles" /? qs[Option[Int]]("page")
    • Client interpreters must omit optional query string parameters that are empty.
    • Server interpreters must accept incoming requests whose optional query string parameters are missing, and they must report a failure for incoming requests whose optional query string parameters are present, but malformed,
    • Documentation interpreters should mark the parameter as optional.
