shopify_draft_proxy - v0.1.0

shopify_draft_proxy/proxy/metafield_definitions

Stateful Gleam port of the metafields/metafield-definitions slice.

The module intentionally keeps the owner-scoped metafield model narrow: Product, ProductVariant, Collection, and Customer owner IDs are accepted for local metafield staging/reads; broader HasMetafields families stay unsupported until their owning domains have evidence and state.

Types

MetafieldDefinitionsError 

pub type MetafieldDefinitionsError {
  ParseFailed(root_field.RootFieldError)
}

Constructors

MetafieldsSetUserError 

pub type MetafieldsSetUserError {
  MetafieldsSetUserError(
    field: List(String),
    message: String,
    code: option.Option(String),
    element_index: option.Option(Int),
  )
}

Constructors

MutationOutcome 

pub type MutationOutcome {
  MutationOutcome(
    data: json.Json,
    store: store.Store,
    identity: synthetic_identity.SyntheticIdentityRegistry,
    staged_resource_ids: List(String),
    log_drafts: List(mutation_helpers.LogDraft),
  )
}

Constructors

UserError 

pub type UserError {
  UserError(
    field: option.Option(List(String)),
    message: String,
    code: String,
  )
}

Constructors 

  • UserError(
  field: option.Option(List(String)),
  message: String,
  code: String,
)

Values

handle_metafield_definitions_query 

pub fn handle_metafield_definitions_query(
  store: store.Store,
  document: String,
  variables: dict.Dict(String, root_field.ResolvedValue),
) -> Result(json.Json, MetafieldDefinitionsError)

handle_query_request 

pub fn handle_query_request(
  proxy: proxy_state.DraftProxy,
  request: proxy_state.Request,
  primary_root_field: String,
  query: String,
  variables: dict.Dict(String, root_field.ResolvedValue),
) -> #(proxy_state.Response, proxy_state.DraftProxy)

Pattern 1: cold LiveHybrid definition catalog/detail reads are just upstream reads. Once a local lifecycle has staged or deleted definitions, keep reads local so read-after-write and read-after-delete behavior does not leak back to Shopify.

is_metafield_definitions_mutation_root 

pub fn is_metafield_definitions_mutation_root(
  name: String,
) -> Bool

is_metafield_definitions_query_root 

pub fn is_metafield_definitions_query_root(name: String) -> Bool

local_has_metafield_definition_state 

pub fn local_has_metafield_definition_state(
  proxy: proxy_state.DraftProxy,
  variables: dict.Dict(String, root_field.ResolvedValue),
) -> Bool

True when the local metafield-definition model must answer reads instead of LiveHybrid passthrough: a lifecycle flow has staged or deleted definitions, or a variable carries a proxy-synthetic definition id.

process 

pub fn process(
  store: store.Store,
  document: String,
  variables: dict.Dict(String, root_field.ResolvedValue),
) -> Result(json.Json, MetafieldDefinitionsError)

process_mutation 

pub fn process_mutation(
  store_in: store.Store,
  identity: synthetic_identity.SyntheticIdentityRegistry,
  request_path: String,
  document: String,
  variables: dict.Dict(String, root_field.ResolvedValue),
) -> Result(MutationOutcome, MetafieldDefinitionsError)

process_mutation_with_upstream 

pub fn process_mutation_with_upstream(
  store_in: store.Store,
  identity: synthetic_identity.SyntheticIdentityRegistry,
  request_path: String,
  document: String,
  variables: dict.Dict(String, root_field.ResolvedValue),
  upstream: upstream_query.UpstreamContext,
) -> Result(MutationOutcome, MetafieldDefinitionsError)

wrap_data 

pub fn wrap_data(data: json.Json) -> json.Json
