# GraphqlD: A graphql implementation for the D Programming language
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:
```JS
{
"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.
## Features
This graphql implementation is based on June 2018 spec.
### Operation Execution
- [x] Scalars
- [x] Objects
- [x] Lists of objects/interfaces
- [x] Interfaces
- [x] Unions
- [x] Arguments
- [x] Variables
- [x] Fragments
- [x] Directives
- [x] Include
- [x] Skip
- [?] Custom (Requires changing the graphqld source)
- [x] Enumerations
- [x] Input Objects
- [x] Mutations
- [ ] Subscriptions (This needs vibe.d websocket integration)
- [x] Async execution (when used with vibe.d blocking resolver are async by
default)
### Validation
- [ ] Arguments of correct type
- [ ] Default values of correct type
- [x] Fields on correct type
- [x] Fragments on composite types
- [X] Known argument names
- [x] Executable Definition
- [ ] Known directives
- [x] Known fragment names
- [x] Known type names
- [x] Lone anonymous operations
- [x] No fragment cycles
- [x] No undefined variables
- [x] No unused fragments
- [x] No unused variables
- [x] Overlapping fields can be merged (this is done during execution)
- [x] Possible fragment spreads
- [ ] Provide non-null arguments
- [x] Scalar leafs
- [x] Unique argument names
- [x] Unique directives per location
- [x] Unique fragment names
- [x] Unique input field names
- [x] Unique operation names
- [x] Unique variable names
- [ ] Variables are input types (this is actually a strange requirement)
- [x] Variables in allowed position
- [x] Single root field
### Schema Introspection
- [x] __typename
- [x] __type
- [x] name
- [x] kind
- [x] description
- [x] fields
- [x] interfaces
- [x] possibleTypes
- [x] enumValues
- [x] inputFields
- [x] ofType
- [x] __schema
- [x] types
- [x] queryType
- [x] mutationType
- [x] subscriptionType
- [x] directives
### Comfort Features
- [ ] Query AST cache
- [ ] Json to resolver argument extractor
- [ ] SQL query generation from AST
- [x] Custom Leaf types (e.g. GQLDCustomLeaf!(std.datetime.DateTime))

## Documentation
The Documentation is still WIP, please have a look at the vibe.d project in the
test folder.
This [file](test/source/app.d:430) gives a good overview on how to use graphqld
with vibe.d.
