    Package Exports

    • @serverless/platform-client

    This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@serverless/platform-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    Serverless Platform SDK

    This Serverless Platform SDK makes it easy to interact with the Serverless Platform and perform operations on it. Please note that there is an existing @serverless/platform-sdk npm module for interacting with the Serverless Inc. SaaS original platform services. This SDK is for the new services, which are multi-cloud, self-hostable and focued on Components. At some point, we will try to merge these SDKs.

    The SDK is light-weight, so that it can be used in the following: CLIs, Dashboards, Back-End Services, FaaS Layers. Please DO NOT add any big Node.js dependencies to this SDK.

    This SDK should guide the interface design between Services and Clients. All Clients and Services MUST use the SDK and should never hardcode API endpoints or FaaS resources identifiers.

    Quick-Start

    If you are working within a Node.js environment, install the Serverless Platform Client SDK via NPM:

    npm i @serverless/platform-client

    If you are working within a web/browser environment, use the CDN hosted Serverless Platform Client SDK:

    This is minified, tree-shaked, browserified. The CDN fetches it directly from NPM, so just reference any npm version, like below.

    This CDN service has several locations in China, so it works well there.

    // In index.html <head></head>
<!-- Load the Serverless Platform (Components) SDK -->
<script src="https://cdn.jsdelivr.net/npm/@serverless/platform-client@0.17.2" async></script>

    You can also pin to the latest version, but this could break at any time:

    // In index.html <head></head>
<!-- Load the Serverless Platform (Components) SDK -->
<script src="https://cdn.jsdelivr.net/npm/@serverless/platform-client" async></script>

    If you are working with the dev environment of the Serverless Platform, set the following environment variable, or configure the client programmatically, as detailed below.

    export SERVERLESS_PLATFORM_STAGE=dev

    Here is how you require, instantiate the Client and use it:

    const { ServerlessSDK } = require('@serverless/platform-client')

sdk = new ServerlessSDK({
  platformStage: 'dev',  // Optional.  Defaults to 'prod'
  accessKey: 'JA98JAJFASLFJSALFJASLFJ', // Optional, but recommended.  Platform Access Key needed to identify all requests.
})

const instances = await sdk.listInstances('my-org')

    serverlessSDK.getDomain(serviceName) ⇒ string

    Gets a domain for a specific service: 'engine', 'registry', 'events-streaming'

    Kind: instance method of ServerlessSDK
    Returns: string - The domain of that service.

    Param Type Default Description
    serviceName string null The name of the Serverless Platform Service you want the domain for.

    serverlessSDK.getUser() ⇒ object

    Get User account

    Kind: instance method of ServerlessSDK
    Returns: object - Returns a user record.

    serverlessSDK.getUserMeta() ⇒ object

    Get User account meta information.

    Kind: instance method of ServerlessSDK
    Returns: object - Returns a data object of custom "meta" information.

    serverlessSDK.saveUserMeta() ⇒ object

    Updates User account meta information. This method fetches meta information and merges it with the meta object you provide before saving.

    Kind: instance method of ServerlessSDK
    Returns: object - Returns a data object of User data.

    serverlessSDK.validateUserAndOrgName(userAndOrgName) ⇒ array

    Validates whether a potential User and Organization name meets the Platform requirements. Most importantly, this calls the Platform to validate whether the User and Organization names are already taken. This method is necessary because every User must have an Organization and we want to be sure both namespaces are availbale, before creating one or the other. In the future, both of these records should be created in the back-end, not on the client-side. Until then, this method is essential.

    Kind: instance method of ServerlessSDK
    Returns: array - Returns an array of validation errors, if any. Otherwise, returns null.

    Param Type Description
    userAndOrgName string The name of the User and Org name.

    serverlessSDK.createUserAndOrg(userAndOrgName) ⇒ object

    In the Serverless Platform, every User must have an Organization by default. This method creates both a User and an Organization record, at the same time. Please note, the endpoint called is specific to Tenants (Organizations), which also has User creation logic within it. This API design is non-sensible and we should consider a better API design ASAP. Until then, this method abstracts over that.

    Kind: instance method of ServerlessSDK
    Returns: object - Returns the newly create Organization.

    Param Type Description
    userAndOrgName string The name of the User and Org name.

    serverlessSDK.createOrg(userAndOrgName) ⇒ object

    Kind: instance method of ServerlessSDK
    Returns: object - Returns the newly create Organization.

    Param Type Description
    userAndOrgName string The name of the Organization you wish to create. WARNING: This also creates a User record if one does not exist under this Organization name. This API design needs improvement.

    serverlessSDK.getOrgByName(orgName) ⇒ object

    Gets an Organization by Organization name.

    Kind: instance method of ServerlessSDK
    Returns: object - Returns the Organization record.

    Param Type Description

    app.name string The name of the Application.
    app.description string The description of the Application.
    app.deploymentProfiles object An object of deployment profiles and stages. This structure is a bit confusing. Look at the back-end service for more details and hopefully we can design this more elegantly in the future.

    serverlessSDK.updateApp(orgName) ⇒ object

    Update an Application within an Organization

    Kind: instance method of ServerlessSDK
    Returns: object - Returns a data object of the updated Application

    Param Type Default Description

    app.description string The description of the Application. This property can be updated.
    app.deploymentProfiles object An object of deployment profiles and stages. This property can be updated. This structure is a bit confusing. Look at the back-end service for more details and hopefully we can design this more elegantly in the future.

    Publishing the SDK

    Before publishing the SDK, be sure to run the pre-publish script, which browserifies the code and updates its documentation, by running: npm run pre-publish within the sdk folder.
