# Transport [transport]
|
|
|
|
This class is responsible for performing the request to {{es}} and handling errors, it also handles sniffing.
|
|
|
|
```js
|
|
const { Client } = require('@elastic/elasticsearch')
|
|
const { Transport } = require('@elastic/transport')
|
|
|
|
class MyTransport extends Transport {
|
|
request (params, options, callback) {
|
|
// your code
|
|
}
|
|
}
|
|
|
|
const client = new Client({
|
|
Transport: MyTransport
|
|
})
|
|
```
|
|
|
|
Sometimes you need to inject a small snippet of your code and then continue to use the usual client code. In such cases, call `super.method`:
|
|
|
|
```js
|
|
class MyTransport extends Transport {
|
|
request (params, options, callback) {
|
|
// your code
|
|
return super.request(params, options, callback)
|
|
}
|
|
}
|
|
```
|
|
|
|
## Supported content types [_supported_content_types]
|
|
|
|
Depending on the `content-type` of the response, the transport will return the body as different types:
|
|
|
|
| Content-Type | JavaScript type |
