This is a node.js wrapper for the desk.com API (it might also work in the browser but only with either a proxy or from a desk.com case template). It'll only support APIv2 which is currently in heavy development, changes happen nearly twice to three times a week. We'll try to keep up with all the changes but things might break unexpectedly.
Now for the fun part ...
This is a basic example of how to create a client and establish a connection. It shows the four request methods supported by the desk.com API (GET, POST, PATCH and DELETE).
var desk = require('desk.js')
, client = desk.createClient({
subdomain: 'devel',
// optional include only if you use a custom domain - see below for details
endpoint: 'https://support.example.com',
// use it with basic auth
username: 'devel@example.com',
password: '12345',
// use it with oauth
consumerKey: 'this-is-my-consumer-key',
consumerSecret: 'and-my-consumer-secret',
token: 'my-access-token',
tokenSecret: 'my-token-secret'
// add a request logger
logger: console,
// allow retry
retry: true
});
client.get('/api/v2/cases', function(err, json, response) {
if (err) throw err;
// the json is the response body already parsed
});
client.post('/api/v2/cases', myNewCaseHash, function(err, json, response) {
if (err) throw err;
// the json is the response body already parsed
});
client.patch('/api/v2/cases/1', { subject: 'New Subject' }, function(err, json, response) {
if (err) throw err;
// the json is the response body already parsed
});
// for resources like articles we also allow delete
client.delete('/api/v2/articles/1', function(err, response) {
if (err) throw err;
// response.statusCode === 201
});This wrapper also allows you to work with collections and resources, follow associations and more ...
// find a resource by url
client.cases().byUrl('/api/v2/cases/1', function(err, myCase) {
if (err) throw err;
// use myCase
});
// find a resource by id
client.cases().byId(1, function(err, myCase) {
if (err) throw err;
// use myCase
});// fetch the first page of the users collection
client.users(function(err, users) {
// the result is an array with additional functions
users.last(function(err, users) {
// users is now pointed to the last page
users.first(function(err, users) {
// back to the first page
});
});
});
// you can also specify the pagination directly
client.users().perPage(10).page(5).exec(function(err, users) {
// users would now be an array of user 51 - 60
users.next(function(err, users) {
// now it would be user 61 - 70
users.previous(function(err, users) {
// and we are back
});
});
});We also support indicators now, so on any page you are you can check if that page has a next/previous page.
// fetch the first page of the cases collection
client.cases(function(err, cases) {
// if we have more than 30 (default page size) cases
// a check for a next page will be true
cases.hasNextPage() === true;
// however the first page will never have a previous page
cases.hasPreviousPage() === false;
// this turns on the last page
cases.last(function(err, cases) {
// we won't have a next page
cases.hasNextPage() === false;
// but we'll have a previous page
cases.hasPreviousPage() === true;
});
});Pagination is pretty obvious but the cool part about pagination or rather resources is the auto-linking. As soon as the resource has a link defined, it'll be navigatable:
{
"_links": {
"self": {
"href": "/api/v2/cases/1",
"class": "case"
},
"message": {
"href": "/api/v2/cases/1/message",
"class": "message"
},
"customer": {
"href": "/api/v2/customers/1",
"class": "customer"
},
"assigned_user": {
"href": "/api/v2/users/2",
"class": "user"
},
"assigned_group": {
"href": "/api/v2/groups/1",
"class": "group"
},
"locked_by": null
}
}client.cases(function(err, cases) {
cases[0].customer(function(err, customer) {
// now you can use the customer
// you could do an update
customer.update({ first_name: 'John', last_name: 'Doe' }, function(err, customer) {
console.log(customer.getFirstName());
// => John
});
});
});desk.js supports create, update and delete methods on resources. However if the API doesn't allow for example deletion, it won't be a method on the resource.
/**
* Create
*/
client.articles().create({
subject: 'Some Subject',
body: 'Some Body',
_links: {
topic: {
href: '/api/v2/topics/1',
'class': 'topic'
}
}
}, function(err, article) {
article.getSubject().should.equal('Some Subject');
article.getBody().should.equal('Some Body');
});
/**
* Update
*/
client.articles(function(err, articles) {
articles[0].update({
subject: 'Some other Subject'
}, function(err, article) {
// use article
});
});
/**
* Delete
*/
client.articles(function(err, articles) {
articles[0].delete(function(err) {
if (err) throw err;
continue;
});
});
/**
* ATTENTION: Case doesn't allow deletion.
*/
client.cases().byId(25, function(err, myCase) {
myCase.delete();
// => Error: No method delete defined on Object Case.
});For each field on the resource it'll automatically create getters and setters:
client.customers().byId(1, function(err, customer) {
console.log(customer.getFirstName());
console.log(customer.getLastName());
console.log(customer.getTitle());
// ...
// for updates you can either use the setters
customer.setFirstName('John');
customer.update(function(err, customer) {})
// or a hash
customer.update({ first_name: 'John' }, function(err, customer) {})
});If your desk.com site uses a custom domain, you should use that URL as the basis for your api calls. If you set the endpoint property when creating your desk.com client, it will use this domain instead of the subdomain value to construct the URL. The URL should be a fully qualified path to your site (e.g. https://yoursupportsite.com)
var desk = require('desk')
, client = desk.createClient({
// Specify to use a custom domain
endpoint: 'https://support.example.com',
// use it with basic auth
username: 'devel@example.com',
password: '12345',
// use it with oauth
consumerKey: 'this-is-my-consumer-key',
consumerSecret: 'and-my-consumer-secret',
token: 'my-access-token',
tokenSecret: 'my-token-secret'
// add a request logger
logger: console,
// allow retry
retry: true
});Sometimes the API is going to return errors, eg. Validation Error. In these cases we bubble the API error through to the callback so you can deal with it however you please.
client.cases().create({
external_id: null,
subject: 'Some Subject',
priority: 5,
description: 'Some Description',
status: 'new',
type: 'email',
labels: ['ignore', 'spam'],
language: null,
custom_fields: {},
message: {
direction: 'in',
status: 'received',
body: 'Some Body',
subject: 'Some Subject'
},
_links: {
customer: {
href: '/api/v2/customers/34290812',
'class': 'customer'
}
}
}, function(err, myCase) {
console.log(err.message);
// => Message requires to, cc or bcc fields to be set to a non-blank value
