# Ovto.fetch

Ovto provides wrapper of [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch), for convenience of calling typical server-side APIs (eg. those generated by `rails scaffold` command.)

`Ovto.fetch` returns Opal's Promise object that calls the API with the specified parameters.

## Examples

GET

```rb
Ovto.fetch('/api/tasks').then{|json_data|
  p json_data
}.fail{|e|  # Network error, 404 Not Found, JSON parse error, etc.
  p e
}
```

POST

```rb
Ovto.fetch('/api/new_task', 'POST', {title: "do something"}).then{|json_data|
  p json_data
}.fail{|e|  # Network error, 404 Not Found, JSON parse error, etc.
  p e
}

```

PUT

```rb
Ovto.fetch('/api/tasks/1', 'PUT', {title: "do something"}).then{|json_data|
  p json_data
}.fail{|e|  # Network error, 404 Not Found, JSON parse error, etc.
  p e
}
```

## CSRF tokens

You don't need to care about CSRF tokens if the server is a Rails app because `Ovto.fetch` automatically send `X-CSRF-Token` header if the page contains a meta tag like `<meta name='csrf-token' content='....' />`.
