AWS SDK for JavaScript

The AWS SDK for JavaScript is a set of developer tools to work AWS services, which is compatible with Yandex Object Storage.

Getting startedGetting started

1. Create a service account.
2. Assign the service account the roles required for your project. For more information about roles, see the Identity and Access Management documentation.
3. Create a static access key.

InstallationInstallation

To install the AWS SDK for JavaScript:

1. Install Node.js.

2. Clone the AWS SDK Code Examples repository. Run the following command in the terminal window:

   git clone https://github.com/awsdocs/aws-doc-sdk-examples
   

SetupSetup

1. Go to the ~/.aws/ directory (for macOS and Linux) or C:\Users\<username>\.aws\ (for Windows).

2. Create a file named credentials with the credentials for Object Storage and copy the following information to it:

   [default]
     aws_access_key_id = <static_key_ID>
     aws_secret_access_key = <secret_key>
   

3. Create a file named config with the default region settings and copy the following information to it:

   [default]
     region=ru-central1
   

   Note

   Some apps designed to work with Amazon S3 do not allow you to specify the region; this is why Object Storage may also accept the us-east-1 value.

To access Object Storage, use the https://storage.yandexcloud.net endpoint.

Code samplesCode samples

You can find a sample bucket creation code in the repository's javascriptv3/example_code/nodegetstarted/src directory.

To connect to Object Storage and create a bucket:

1. Install dependencies as described in the javascriptv3/example_code/nodegetstarted/package.json file:

   npm install node -g
   cd aws-doc-sdk-examples/javascriptv3/example_code/nodegetstarted
   npm install
   

2. In the javascriptv3/example_code/nodegetstarted/src/libs/ directory, open the s3Client.js file with a description of the Object Storage client.

3. Replace the file contents with the code below:

   import { S3Client } from "@aws-sdk/client-s3";
   // Setting the region Object Storage
   const REGION = "ru-central1";
   // Setting the endpoint Object Storage
   const ENDPOINT = "https://storage.yandexcloud.net";
   // Creating a client for Object Storage
   const s3Client = new S3Client({ region: REGION, endpoint: ENDPOINT });
   export { s3Client };
   

4. In the javascriptv3/example_code/nodegetstarted/src/ directory, open the sample.js file with the code for creating a bucket and an object in it.

   sample.js contents

   // Importing clients and AWS SDK commands to work with Node.js
   import { PutObjectCommand, CreateBucketCommand } from "@aws-sdk/client-s3";
   import { s3Client } from "./libs/s3Client.js";
   
   // Setting parameters
   const params = {
     Bucket: "<bucket_name>", // Bucket name, such as 'sample-bucket-101'.
     Key: "<object_name>", // Object name, such as 'sample_upload.txt'.
     Body: "<object_contents>", // Object contents, such as 'Hello world!".
   };
   
   const run = async () => {
     // Creating a bucket
     try {
       const data = await s3Client.send(
           new CreateBucketCommand({ Bucket: params.Bucket })
       );
       console.log(data);
       console.log("Successfully created a bucket called ", data.Location);
       return data; // For modular testing.
     } catch (err) {
       console.log("Error", err);
     }
     // Creating an object and uploading it to the bucket
     try {
       const results = await s3Client.send(new PutObjectCommand(params));
       console.log(
           "Successfully created " +
           params.Key +
           " and uploaded it to " +
           params.Bucket +
           "/" +
           params.Key
       );
       return results; // For modular testing.
     } catch (err) {
       console.log("Error", err);
     }
   };
   run();
   

5. Under const params, set a name for the bucket and a name and contents for the bucket object.

6. Run the application:

   node sample.js
