##Using `Remote` functions and `Request` objects
|
|
|
|
Each remote function returns a `Request` object, which is an `EventEmitter`. You can listen for success or failure events from each request or, alternatively, you can provide a callback.
|
|
|
|
Here is an example, using `request_server_info()`, of how `Remote` functions can be used with event listeners (the first code block) or with a callback (the second block):
|
|
|
|
`Remote` function with `Request` event listeners:
|
|
```js
|
|
var request = remote.request_server_info();
|
|
request.on('success', function(res) {
|
|
//handle success
|
|
});
|
|
request.on('error', function(err) {
|
|
//handle error
|
|
});
|
|
request.request(); // this triggers the request if it has not already been sent to the server
|
|
```
|
|
|
|
`Remote` function with a callback:
|
|
```js
|
|
remote.request_server_info(function(err, res) {
|
|
if (err) {
|
|
//handle error
|
|
} else {
|
|
//handle success
|
|
}
|
|
});
|
|
```
|
|
|
|
NOTE: See the [`Remote` functions reference](https://github.com/ripple/ripple-lib#Remote_functions_reference) section below for documentation on all of the available functions.

##Submitting a transaction
|
|
|
|
```js
|
|
var Remote = require('ripple-lib').Remote;
|
|
var Amount = require('ripple-lib').Amount;
|
|
|
|
var MY_ADDRESS = 'rrrMyAddress';
|
|
var MY_SECRET = 'secret';
|
|
var RECIPIENT = 'rrrRecipient';
|
|
var AMOUNT = Amount.from_human('1XRP');
|
|
|
|
var remote = new Remote({ /* configuration */ });
|
|
|
|
remote.connect(function() {
|
|
remote.set_secret(MY_ADDRESS, MY_SECRET);
|
|
|
|
var transaction = remote.transaction();
|
|
|
|
transaction.payment(MY_ADDRESS, RECIPIENT, AMOUNT);
|
|
|
|
transaction.submit(function(err, res) {
|
|
/* handle submission errors / success */
|
|
});
|
|
});
|
|
``` |
