Install the Node.js client SDK

Install the SDK. Run the following command in the root directory of your Node.js project.

npm install @alicloud/mpserverless-node-sdk@1.2.3 --save

Initialize the SDK. Add the following SDK initialization code to your project.

// Reference the SDK
const MPServerless = require('@alicloud/mpserverless-node-sdk').default;
// Initialize the SDK
const client = new MPServerless({
  	timeout: 60 * 1000,
    spaceId: 'mp-db4dd657-7041-470a-90xxxxx',
    endpoint: 'https://api.next.bspapp.com',
    serverSecret: '-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBgkqhki******G9w0BAQE7V0sQaj\n-----END PRIVATE KEY-----',
});

Where:

• You can obtain the spaceId and endpoint after you create a service space in the EMAS Serverless console. For more information, see Create your first service space.

• You can obtain serverSecret by calling the DescribeSpaceClientConfig operation.

Call the SDK. The following code provides an example of calling the EMAS Serverless SDK in Node.js. For more information, see Cloud Function API documentation and Data Storage API documentation.

// Cloud function
try {
  const res = await client.function.invoke('testFunction');
  console.log('function invoke result: ', res);
} catch (err) {
  console.log('function invoke error: ', err);
}
// Cloud database
try {
  const res = await client.db.collection('testTable').count({});
  console.log('db service result: ', res);
} catch (err) {
  console.log('db service error: ', err);
}
