Description

A javascript client to talk to SIS. Designed to work within node or modern browsers (native JSON api and XMLHttpRequest with CORS support).

Usage

Node

var SIS = require('sis');
var SISClient = SIS.client({'url' : 'http://sis.host'});

The code is designed to be an npm module, but it is not a public module to install.

Browser

<script src='/path/to/sis-client.js'></script>

var SISClient = SIS.client({'url' : 'http://sis.host'});

Working with a SIS Client

// Get the first page of hooks
SISClient.hooks.list(function(err, result) {
    // result is an array of hook objects
});

// Get a single schema
SISClient.schemas.list({'limit' : 1}, function(err, result) {
    // result is an array of schemas of length 1
});

// Create a hiera entry
SISClient.hiera.create({ 'name' : 'entry', 'hieradata' : { 'key1' : 'value1' }}, function(err, result) {
    // result is the created hiera entry
});

// Delete the entity of type 'entity_name' with id 'foo'
SISClient.entities('entity_name').delete('foo', function(err, result) {
    // result is a boolean indicating success
});

All callbacks receive an err as the first parameter and the result of the API call as the second.

Authentication / Token Support

SIS Clients must use authentication tokens for most operations. The token can be provided in a number of ways.

Add a token field to the object passed to the SIS function. I.E. var client = SIS.client({'url' : 'http://sis.host', 'token' : '<token goes here>'});
Call authenticate on the client to authenticate via username/password and use the returned temporary token. The following example shows the use of authenticate:

var SISClient = SIS.client({'url' : 'http://sis.host'});
SISClient.authenticate('user', 'password', function(err, authenticated) {
    if (err || !authenticated) {
        // authentication failed
    } else {
        // authentication succeeded and the client
        // token has been set
    }
});

The object returned by SISClient.hooks, SISClient.schemas, SISClient.hiera, and SISClient.entities(entity_name) all interact with the appropriate endpoints and expose the following interface:

list(queryOpts, callback)

This maps to a GET / request against the endpoint.

queryOpts is an optional JSON object that constructs the query string. Fields in the object include:
- q : a json object specifying the filter
- limit : the number of items to return
- offset : offset into the number of objects to return

Consult the SIS documentation for further information.

An array of objects is returned to the callback on success.

get(id, callback)

This maps to a GET /id request against the endpoint.

id : a string representing the ID of the object to receive. For schemas, hooks, and hiera, this is the name. For entities, it is the _id.

A single object is returned to the callback on success.

create(obj, callback)

This maps to a POST / request against the endpoint.

obj : a valid JSON object conforming to the endpoint specification. An array of objects implies a bulk insert operation.

The created object is returned to the callback on success. In the case of a bulk insert, an object that looks like the following is returned:

{
    // list of objects that look like { err : error_object, value : object_that_failed_to_insert }
    errors : [],
    // list of objects that were successfully inserted
    success : []
}

update(obj, callback)

This maps to a PUT '/:obj_id' request against the endpoint. The _id is used for entities, and 'name' is used for others.

obj : a valid JSON object conforming to the endpoint specification. Typically retrieved from list or get.

The updated object is returned to the callback on success.

updateById(id, obj, query, callback)

This maps to a PUT '/:id' request against the endpoint.

id : the ID of the object. In non entities, the name. In entities where the schema has an id_field, the id or _id.
obj : the payload to send
query : update modifiers. This would be to specify CAS operations or upserts.

delete(obj, callback)

This maps to a DELETE '/id' request against the appropriate v1 endpoint.

obj : either a string id or an object retrieved from list or get

true is returned to the callback on success.

Testing

All tests require a test server to hit. Ensure that it is running and that test/test-config.js points to it.

Testing Node

One time setup: npm install -g mocha

mocha

Testing in a Browser

Run make webroot to produce the webroot folder. Then open webroot/index.html in your favorite browser.
