A Golang driver for FaunaDB.
Note: This driver supports an older version of the Fauna API. The latest version of the official Fauna Golang Driver is located here (we encourage all new development to use this new version where possible).
Currently, the driver is tested on:
- 1.13
- 1.14
- 1.15
- 1.16
To get the latest version run:
go get github.com/fauna/faunadb-go/v4/faunadbPlease note that our driver undergoes breaking changes from time to time, so depending on our main branch is not recommended.
It is recommended to use one of the following methods instead:
For better usage, we recommend that you import this driver with an alias import.
To import a specific version when using go get, use:
import f "github.com/fauna/faunadb-go/v4/faunadb"package main
import (
"fmt"
f "github.com/fauna/faunadb-go/v4/faunadb"
)
type User struct {
Name string `fauna:"name"`
}
func main() {
client := f.NewFaunaClient("your-secret-here")
res, err := client.Query(f.Get(f.Ref(f.Collection("user"), "42")))
if err != nil {
panic(err)
}
var user User
if err := res.At(f.ObjKey("data")).Get(&user); err != nil {
panic(err)
}
fmt.Println(user)
}package main
import f "github.com/fauna/faunadb-go/v4/faunadb"
func main() {
secret := ""
dbClient = f.NewFaunaClient(secret)
var ref f.RefV
value, err := dbClient.Query(f.Get(&ref))
if err != nil {
panic(err)
}
err = value.At(f.ObjKey("ref")).Get(&docRef)
var subscription f.StreamSubscription
subscription = dbClient.Stream(docRef)
err = subscription.Start()
if err != nil {
panic("Panic")
}
for a := range subscription.StreamEvents() {
switch a.Type() {
case f.StartEventT:
// do smth on start event
case f.HistoryRewriteEventT:
// do smth on historyRewrite event
case f.VersionEventT:
// do smth on version event
case f.ErrorEventT:
// do smth on error event
subscription.Close() // if you want to close streaming on errors
}
}
}package main
import f "github.com/fauna/faunadb-go/v4/faunadb"
func main() {
secret := ""
dbClient = f.NewFaunaClient(secret)
var ref f.RefV
value, err := dbClient.Query(f.Get(&ref))
if err != nil {
panic(err)
}
type OmitStruct struct {
Name string `fauna:"name,omitempty"`
Age int `fauna:"age,omitempty"`
Payment float64 `fauna:"payment,omitempty"`
AgePointer *int `fauna:"agePointer,omitempty"`
PaymentPointer *float64 `fauna:"paymentPointer,omitempty"`
}
_, err := dbClient.Query(
f.Create(f.Collection("categories"), f.Obj{"data": OmitStruct{Name: "John", Age: 0}}))
if err != nil {
panic(err)
}
}Result (empty/zero fields will be ignored):
{
"ref": Ref(Collection("categories"), "295143889346494983"),
"ts": 1617729997710000,
"data": {
"name": "John"
}
}
Driver uses http2 by default. To use http 1.x provide custom http client to FaunaClient
package main
import f "github.com/fauna/faunadb-go/v4/faunadb"
func main() {
secret := ""
customHttpClient := http.Client{}
dbClient = f.NewFaunaClient(secret, f.HTTP(&customHttpClient))
}For more information about Fauna Query Language (FQL), consult our query language [reference documentation](https://docs.fauna.com/fauna/v4/api/fql/).
Specific reference documentation for the driver is hosted at GoDoc.
Most users found tests for the driver as a very useful form of documentation Check it out here.
GitHub pull requests are very welcome.
Run go get -t ./... in order to install project's dependencies.
Run tests against FaunaDB Cloud by passing your root database key to the
test suite, as follows: FAUNA_ROOT_KEY="your-cloud-secret" go test ./....
If you have access to another running FaunaDB database, use the
FAUNA_ENDPOINT environment variable to specify its URI.
Alternatively, tests can be run via a Docker container with
FAUNA_ROOT_KEY="your-cloud-secret" make docker-test (an alternate
Debian-based Go image can be provided via RUNTIME_IMAGE).
Tip: Setting the FAUNA_QUERY_TIMEOUT_MS environment variable will
set a timeout in milliseconds for all queries.
