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/[email protected]" 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')

Kind: instance method of ServerlessSDK
Returns: boolean - Will return true if the websocket connection is active.

serverlessSDK.publish() ⇒ null

Publishes a Serverless Platform Event via Websockets. The use-case for this is asynchronous publishing, where you do not want to synchronous auth requests, where every message must be authorized first, adding latency.

Kind: instance method of ServerlessSDK

serverlessSDK.publishSync() ⇒ null

Publishes a Serverless Platform Event via HTTP API. The use-case for this is synchronous publishing, where you do not want to open a websockets connection.

Kind: instance method of ServerlessSDK

serverlessSDK.createComponent(orgName, componentName)

Returns a new Component as a Javascript object.

Kind: instance method of ServerlessSDK

| Param | Type | Default | Description | | --- | --- | --- | --- | | orgName | * | | The name of the Serverless Platform Organization. | | componentName | * | | The name of the Serverless Platform Stage. |

serverlessSDK.publishComponent(componentDefinition) ⇒ object

This method publishes a Component to the Serverless Platform Registry. This method accepts a Component Definition (e.g. serverless.component.yml) as an object. In the Component Definition, it looks at the 'main' property to find the path to the Component source directory. Then it collects that directory, adds in the special Component Handler, and packages everything into a zip file. After that, it fetches secure upload URLs and uploads the Component to the Serverless Registry. Once a Component has been uploaded to the Registry, the Registry must do some background processing to publish it, while that's happening, this method polls the API to see when the Component is finished being processed, and then returns the published definition.

Kind: instance method of ServerlessSDK
Returns: object - The published Component definition is returned from the Platform API.

| Param | Type | Description | | --- | --- | --- | | componentDefinition | * | An object containing the properties of a Component. |

| Param | Type | Default | Description | | --- | --- | --- | --- | | componentName | * | | The name of the Component within the Registry. | | componentVersion | * | | The version of a specific Component within the Registry. If this is not included, this method will always return the latest version. |

Returns a properly formatted ID for an Instance

Kind: instance method of ServerlessSDK
Returns: object - Returns a properly formatted ID for an Instance
