malli-forms.middleware — org.clojars.hsartoris/malli-forms 0.0.102

Middleware support for different use cases of malli-forms

remove-empty-params clj

(remove-empty-params handler)

Middleware that removes entirely any kv pairs that come from a form with an empty string as value. This should occur before unnesting params, as it becomes very difficult to track down empty strings in potentially deeply- nested data structures.

schema-endpoint clj

(schema-endpoint handler schema)

(schema-endpoint handler schema options)

(schema-endpoint handler schema placeholder options)

Middleware that takes a schema and an optional map of malli options, wrapping a handler to render a form for the schema on GET requests, and to validate the input on POST, re-rendering the form with any validation errors, or passing the validated input to the handler function under the key ::mf/value, and the full result of parsing under ::mf/result.

Assumes you have upstream logic to handle wrapping a response with a hiccup body, and rendering appropriately.

See the schema definition of :malli-forms/options for specific keys that can be provided to control the behavior of malli-forms. Of course other keys for malli can also be passed here.

schema-endpoint-reitit clj

Middleware in the data-driven style for reitit. Mounts schema-endpoint, detecting ::mf/schema and other matching namespaced keys from the route config.

stub-handler clj

(stub-handler {:malli-forms/keys [result value] :as req})

Not middleware. Use with schema-endpoint middleware to generate a simple page for inspecting output of handle-submit.
