# init

Before calling the Cloud Base APIs, you need to call the initialization method init once (globally only once)

The init method is defined as below:

function init(options): void

The init method accepts an optional options parameter, and such a method has no return value.

The options parameter defines the default settings for Cloud Base, which are used as the default settings for all other cloud APIs called later on. The optional settings provided by options are as follows:

Field	Data Type	Required	Default	Description
env	string \| object	No	default	The default environment settings. The environment ID in the form of an incoming string can be used to specify the default environment for all services, while the incoming object can be used to specify the default environment for each specific service. Refer to the detailed definition below.

When the incoming env parameter is an object, it can be used to specify the default environment for each service. The optional fields are as below:

Field	Data Type	Required	Default	Description
database	string	No	default	The default environment settings of database API
storage	string	No	default	The default environment settings of storage API
functions	string	No	default	The default environment settings of cloud function API

Sample code:

const cloud = require('wx-server-sdk')
cloud.init({
  env: 'test-x1dzi'
})

Please note that wx-server-sdk is no longer compatible with the callback of success, fail, and complete, and only Promise is returned.
