Graphql is a query language for apis. Given a query like for the schema in folder test.
{
shipsselection(ids:[44,45]) {
id
commander {
name
}
}
}
You get back json that looks like:
{
"error": [],
"data": {
"shipsselection": [
{
"id": 44,
"commander": {
"name": "Kathryn Janeway"
}
},
{
"id": 45,
"commander": {
"name": "Jonathan Archer"
}
}
]
}
}Graphiql type-ahead works, this makes schema introspection a lot nicer.
This graphql implementation is based on June 2018 spec.
- Scalars
- Objects
- Lists of objects/interfaces
- Interfaces
- Unions
- Arguments
- Variables
- Fragments
- Directives
- Include
- Skip
- [?] Custom (Requires changing the graphqld source)
- Enumerations
- Input Objects
- Mutations
- Subscriptions (This needs vibe.d websocket integration)
- Async execution (when used with vibe.d blocking resolver are async by default)
- Arguments of correct type
- Default values of correct type
- Fields on correct type
- Fragments on composite types
- Known argument names
- Executable Definition
- Known directives
- Known fragment names
- Known type names
- Lone anonymous operations
- No fragment cycles
- No undefined variables
- No unused fragments
- No unused variables
- Overlapping fields can be merged (this is done during execution)
- Possible fragment spreads
- Provide non-null arguments
- Scalar leafs
- Unique argument names
- Unique directives per location
- Unique fragment names
- Unique input field names
- Unique operation names
- Unique variable names
- Variables are input types (this is actually a strange requirement)
- Variables in allowed position
- Single root field
- __typename
- __type
- name
- kind
- description
- fields
- interfaces
- possibleTypes
- enumValues
- inputFields
- ofType
- __schema
- types
- queryType
- mutationType
- subscriptionType
- directives
- Query AST cache
- Json to resolver argument extractor
- SQL query generation from AST
- Custom Leaf types (e.g. GQLDCustomLeaf!(std.datetime.DateTime))
Thank you to graphql-dot for the excelent list of features
The Documentation is still WIP, please have a look at the vibe.d project in the test folder. This file gives a good overview on how to use graphqld with vibe.d.
