# Go JSON Mapper (gojsonmapper)

This is a simple library that allows you to map different JSON objects to each other.

## Example

This example shows how to map a JSON object to another JSON object.

### Mapping

```json
{
    "name": "data.name",
    "address": "data.addresses[0]"
}
````

### Input JSON

```json
{
    "data": {
        "name": "John Doe",
        "addresses": [
            "123 Main St"
        ]
    }
}
```

### Output JSON

```json
{
    "name": "John Doe",
    "address": "123 Main St"
}
```

## Usage

### Read Mapping

```go
mapping, err := ReadMapping("mapping.json")
if err != nil {
    log.Fatal(err)
}
```

### Map Input

```go
mapper := NewMapper(mapping)
output, err := mapper.Map(input)
if err != nil {
    log.Fatal(err)
}
fmt.Println(output)
```
