nforce-metadata

nforce-metadata
===============

An nforce plugin that facilitates working with the metadata api

Installation

First, install nforce-metadata with npm

``bash
$ npm install nforce-metadata
`

Load the plugin

`js
var nforce = require('nforce');

// load the nforce-metadata plugin
require('nforce-metadata')(nforce);

var org = nforce.createConnection({
clientId: '',
clientSecret: '',
redirectUri: '',
username: process.env.SFUSER,
password: process.env.SFPASS,
metaOpts: { // options for nforce-metadata
interval: 2000 // poll interval can be specified (optional)
},
plugins: ['meta'] // loads the plugin in this connection
});
`

Usage

nforce-metadata allows you to make requests to the Salesforce
Metadata API just as easily as you can make requests to the
REST API using the nforce base module.

The methods are all under the meta namespace in the
connection object. Here is an example call.

`js
org.authenticate().then(function(){
return org.meta.listMetadata({
queries: [
{ type: 'CustomObject' },
{ type: 'CustomField' },
{ type: 'ApexClass' }
]
});
}).then(function(meta) {
_.each(meta, function(r) {
console.log(r.type + ': ' + r.fullName + ' (' + r.fileName + ')');
});
}).error(function(err) {
console.error(err);
});
`

Just like nforce v1.0.0 and higher, you can either supply a
callback to the api methods or you can omit the callback
and use the returned Promise for async control flow.

See, callbacks work too...

`js
var md = [
{
fullName: 'Test_Obj__c.Foo__c',
label: 'Foo Bar',
length: 100,
type: 'Text'
}
];

org.meta.createMetadata({ type: 'CustomField', metadata: md }, function(err, res) {
if(err) return console.error(err);
console.log(res);
});
`

Pollers

deployAndPoll() and retrieveAndPoll() calls automatically poll for status updates. A
poller EventEmitter object is returned that provides and evented interface the the polling.
Using the poller is quite easy. Here is an example.

`js
org.authenticate().then(function(){
var archive = archiver('zip')
.directory('examples/src', 'src')
.finalize();

var promise = org.meta.deployAndPoll({
zipFile: archive
});

promise.poller.on('poll', function(res) {
console.log('poll status: ' + res.status);
});

return promise;
}).then(function(res) {
console.log('completed: ' + res.status);
}).error(function(err) {
console.error(err);
});
`

Examples

Many example files are included in the examples/ directory. To run the examples,
make sure that you have your SFUSER and SFPASS environment variables set to your
Salesforce username and password respectively.

Connection API

$3

Deploy metadata to a Salesforce organization.

[Salesforce Documentation]
(https://www.salesforce.com/us/developer/docs/api_meta/Content/meta_deploy.htm)

opts:

* oauth: (Object:Optional) The oauth object. Required in multi-user mode.
* zipFile: (Buffer|Stream|String:Required) A zip file containing metadata for deployment.
This should be a Buffer, a Stream, or a base64 encoded String representing a zip file.
* deployOptions: (Object:Optional) Encapsulates options for determining which packages
or files are deployed.
* allowMissingFiles: (Boolean:Optional) Specifies whether a deploy succeeds even if
files that are specified in package.xml but are not in the .zip file
* autoUpdatePackage: (Boolean:Optional) If a file is in the .zip file but not specified
in package.xml, specifies whether the file should be automatically added to the package
(true or not false). A retrieve() is automatically issued with the updated package.xml
that includes the .zip file.
* checkOnly: (Boolean:Optional) Indicates whether Apex classes and triggers are
saved to the organization as part of the deployment (false) or not (true). Defaults
to false. Any errors or messages that would have been issued are still generated.
This parameter is similar to the Salesforce Ant tool’s checkOnly parameter.
* ignoreWarnings: (Boolean:Optional) Indicates whether a warning should allow
a deployment to complete successfully (true) or not (false). Defaults to false.
* performRetrieve: (Boolean:Optional) Indicates whether a retrieve() call is
performed immediately after the deployment (true) or not (false). Set to true in
order to retrieve whatever was just deployed.
* purgeOnDelete: (Boolean:Optional) If true, the deleted components in the
destructiveChanges.xml manifest file aren't stored in the Recycle Bin. Instead,
they become immediately eligible for deletion.
* rollbackOnError: (Boolean:Optional) Indicates whether any failure causes a
complete rollback (true) or not (false). If false, whatever set of actions can be performed
without errors are performed, and errors are returned for the remaining actions. This
parameter must be set to true if you are deploying to a production organization.
The default is false.
* runAllTests: (Boolean:Optional) If true, all Apex tests defined in the organization
are run.
* runTests: (String[]:Optional) A list of Apex tests to be run during deployment.
Specify the class name, one name per instance.
* singlePackage: (Boolean:Optional) Indicates whether the specified .zip file points
to a directory structure with a single package (true) or a set of packages (false).

* zipFile: (Buffer|Stream|String:Required) A zip file containing metadata for deployment.
This should be a Buffer, a Stream, or a base64 encoded String representing a zip file.
* deployOptions: (Object:Optional) Encapsulates options for determining which packages
or files are deployed. See deploy() for all options.
