||
| ```go | ||
| func New(config ...Config) Storage | ||
| func (s *Storage) Get(key string) ([]byte, error) | ||
| func (s *Storage) Set(key string, val []byte, exp time.Duration) error | ||

| func (s *Storage) Reset() error | ||
| func (s *Storage) Close() error | ||
| func (s *Storage) Conn() *cloudflare.API | ||
| ``` | ||
|
|
||
| ### Installation | ||
|
|
||
| ```bash | ||
| go mod init github.com/<user>/<repo> | ||
| ``` | ||
|
|
||
| And then install the Cloudflare KV implementation: | ||
|
|
||
| ```bash | ||
| go get github.com/gofiber/storage/cloudflarekv | ||
| ``` | ||
|
|
||
| ### Examples | ||
|
|
||
| Import the storage package. | ||
|
|
||
| ```go | ||
| import "github.com/gofiber/storage/cloudflarekv" | ||
| ``` | ||
|
|
||
| You can use the following methods to create storage. The Key must be an API Token generated with at least `Account.Workers KV Storage` permission. Check the [Create API Token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/) documentation to generate one. | ||
|
|
||
| ```go | ||
| // Initialize default config | ||
| store := cloudflarekv.New() | ||
|
|
||
| store := cloudflarekv.New(cloudflarekv.Config{ | ||
| Key: "", | ||
| Email: "", | ||
| AccountID: "fiber", | ||
| NamespaceID: "fiber", | ||
| Reset: false, | ||
| }) | ||
|
|
||
| ``` | ||
|
|
||
| ### Config | ||
|
|
||
| ```go | ||
| type Config struct { | ||
|
|
||
| // Cloudflare Auth Token | ||
| // | ||
| // Optional. Default is "" | ||
| Key string | ||
|
|
||
| // Cloudflare Email | ||
| // | ||
| // Optional. Default is "" | ||
| Email string | ||
|
|
||
| // Account id | ||
| // | ||
| // Optional. Default is "fiber" | ||
| AccountID string | ||
|
|
||
| // Namespace id | ||
| // | ||
| // Optional. Default is "fiber" | ||
| NamespaceID string | ||
|
|
||
| // Reset clears any existing keys in existing Table | ||
| // | ||
| // Optional. Default is false | ||
| Reset bool | ||
| } | ||
| ``` | ||
|
|
||
| ### Default Config | ||
|
|
||
| ```go | ||
| var ConfigDefault = Config{ | ||
| Key: "", | ||
| Email: "", | ||
| AccountID: "fiber", | ||
| NamespaceID: "fiber", | ||
| Reset: false, | ||
| } | ||

| ### Structs | ||
|
|
||
| ```go | ||
| type Storage struct { | ||
| // contains filtered or unexported fields | ||
| } | ||
|
|
||
| type Entry struct { | ||
| Value []byte | ||
| Exp time.Time | ||
| } | ||
|
|
||
| type Config struct { | ||
| CustomFuncs *CustomFuncs | ||
| } | ||
|
|
||
| type CustomFuncs struct { | ||
| GetFunc func(key string) ([]byte, error) | ||
| SetFunc func(key string, val []byte, exp time.Duration) error | ||
| DeleteFunc func(key string) error | ||
| ResetFunc func() error | ||
| CloseFunc func() error | ||
| ConnFunc func() map[string]Entry | ||
| KeysFunc func() ([][]byte, error) | ||
| } | ||
| ``` | ||
|
|
||
| ### Functions | ||
| ```go | ||
| // New creates a new Storage instance. You can optionally pass a Config. | ||
| func New(config ...Config) *Storage | ||
|
|
||
| // Get retrieves the value associated with the given key. | ||
| func (s *Storage) Get(key string) ([]byte, error) | ||
|
|
||
| // Set sets the value for the given key, with an optional expiration duration. | ||
| func (s *Storage) Set(key string, val []byte, exp time.Duration) error | ||
|
|
||
| // Delete removes the value associated with the given key. | ||
| func (s *Storage) Delete(key string) error | ||
|
|
||
| // Reset clears all values from the storage. | ||
| func (s *Storage) Reset() error | ||
|
|
||
| // Close performs any necessary cleanup when the storage is no longer needed. | ||
| func (s *Storage) Close() error | ||
|
|
||
| // Conn returns a copy of the current state of the storage. | ||
| func (s *Storage) Conn() map[string]Entry | ||
|
|
||
| // Keys returns a list of all keys in the storage. | ||
| func (s *Storage) Keys() ([][]byte, error) | ||
|
|
||
| // SetCustomFuncs allows you to set custom functions for the storage operations. | ||
| func (s *Storage) SetCustomFuncs(custom *CustomFuncs) | ||
| ``` | ||
|
|
||
| ## Installation | ||
| MockStorage is tested on the 2 last [Go versions](https://golang.org/dl/) with support for modules. So make sure to initialize one first if you didn't do that yet: | ||
| ```bash | ||
| go mod init github.com/<user>/<repo> | ||
| ``` | ||
| And then install the mockstorage implementation: | ||
| ```bash | ||
| go get github.com/gofiber/storage/mockstorage | ||
| ``` | ||
|
|
||
| ## Examples | ||
| Import the storage package. | ||
| ```go | ||
| import "github.com/gofiber/storage/mockstorage" | ||
| ``` | ||
|
|
||
| You can use the following possibilities to create a storage: | ||
| ```go | ||
| // Initialize default config | ||
| store := mockstorage.New() | ||
|
|
||
| // Set a value in the storage. | ||
| err := store.Set("key1", []byte("value1"), 0) | ||
| if err != nil { | ||
| // handle error | ||
| } | ||
|
|
||
| // Get a value from the storage. | ||
| val, err := store.Get("key1") | ||
| if err != nil { | ||
| // handle error | ||
| } | ||
| fmt.Println(string(val)) // prints "value1" | ||
|
|
||
| // Delete a value from the storage. | ||
| err = store.Delete("key1") | ||
| if err != nil { | ||
| // handle error | ||
| } | ||
|
|
||
| // Mocking storage operations in tests: | ||
| func TestMyFunction(t *testing.T) { | ||
| // Create a new instance of MockStorage | ||
| store := mockstorage.New() | ||
|
|
||
| // Mock the Set function | ||
| store.SetCustomFuncs(&mockstorage.CustomFuncs{ | ||
| Set: func(key string, val []byte, exp time.Duration) error { | ||
| if key == "expectedKey" && string(val) == "expectedValue" { | ||
| return nil | ||
| } | ||
| return errors.New("unexpected key or value") | ||
| }, | ||
| }) | ||
|
|
||
| // Call the function you want to test, which should call store.Set | ||
| err := MyFunction(store) | ||
|
|
||
| // Check that the function behaved as expected | ||
| if err != nil { | ||
| t.Errorf("MyFunction returned an error: %v", err) | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| > **Note:** In the `mockstorage` package, expiration of data is not handled automatically in the background. The data is only marked as expired and removed when you attempt to `Get()` it after its expiration time. If you're using a custom `Get()` function or accessing the data directly using the `Conn()` function, expired data will not be removed. Keep this in mind when writing your tests. | ||
| ## Config | ||
| ```go | ||
| type Config struct { | ||
| CustomFuncs *CustomFuncs | ||
| } | ||
| ``` | ||
|
|
||
| ## Default Config | ||
| ```go | ||
| var ConfigDefault = Config{ | ||
| CustomFuncs: &CustomFuncs{ | ||
| GetFunc: nil, | ||
| SetFunc: nil, | ||
| DeleteFunc: nil, | ||
| ResetFunc: nil, | ||
| CloseFunc: nil, | ||
| ConnFunc: nil, | ||
| KeysFunc: nil, | ||
| }, | ||
| } | ||
| ``` |
