trait Path[A] extends 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.

Attributes

Note

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

trait 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.

trait 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.

trait 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.

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
