type FileLoader ¶

type FileLoader interface {
	// The file path that we wish to load.
	Filename() string

	// Check if the file exists.
	Exists() (bool, error)

	// Read the file and return a byte array of its content.
	Load() ([]byte, error)
}

File loader.

A utility that provides file opening functionality wrapped in a mockable interface.

To use:

1. Create an instance with the file path you wish to load:

```go

load := fileloader.NewWithFile("/path/to/file")

```

2. Check it exists (optional):

```go

found, err := load.Exists()

if err != nil {
	panic("File does not exist: " + err.Error())
}

```

3. Load your file:

```go

data, err := load.Load()
if err != nil {
	panic("Could not load file: " + err.Error())
}

```

The `Load` method returns the file content as a byte array.
