dynamodb-admin

npm

GUI for DynamoDB Local, dynalite, localstack etc.

Usage

Use as globally installed app

npm install -g dynamodb-admin

dynamodb-admin --dynamo-endpoint=http://localhost:8000

Options:

  • --open / -o - opens server URL in a default browser on start
  • --port PORT / -p PORT - Port to run on (default: 8001)
  • --host HOST / -h HOST - Host to run on (default: localhost)
  • --dynamo-endpoint - DynamoDB endpoint to connect to (default: http://localhost:8000).
  • --skip-default-credentials - Skip setting default credentials and region. By default the accessKeyId/secretAccessKey are set to "key" and "secret" and the region is set to "us-east-1". If you specify this argument then you need to ensure that credentials are provided some other way. See https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/setting-credentials-node.html for more details on how default credentials provider works.

Environment variables HOST, PORT and DYNAMO_ENDPOINT can also be used to set the respective options.

If you use a local dynamodb that cares about credentials, you can configure them by using the following environment variables AWS_REGION AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY or specify the --skip-default-credentials argument and rely on the default AWS SDK credentials resolving behavior.

For example with the amazon/dynamodb-local docker image you can launch dynamodb-admin with:

AWS_REGION=eu-west-1 AWS_ACCESS_KEY_ID=local AWS_SECRET_ACCESS_KEY=local dynamodb-admin

If you are accessing your database from another piece of software, the AWS_ACCESS_KEY_ID used by that application must match the AWS_ACCESS_KEY_ID you used with dynamodb-admin if you want both to see the same data.

By default dynamodb-admin sets a default key/secret to values "key" and "secret" and the region to "us-east-1".

Use as a library in your project

This requires AWS SDK v3. If you depend on AWS SDK v2 then you need to use dynamodb-admin v4.

import { DynamoDBClient } from '@aws-sdk/client-dynamodb';
import { createServer } from 'dynamodb-admin';

const dynamoDbClient = new DynamoDBClient();

const app = createServer({ dynamoDbClient });

const host = 'localhost';
const port = 8001;
const server = app.listen(port, host);
server.on('listening', () => {
  const address = server.address();
  console.log(`  listening on http://${address.address}:${address.port}`);
});

Development

Run npm run build and then DYNAMO_ENDPOINT=http://localhost:8000 npm run start to start dynamodb-admin.

You can set up a build watcher in a separate terminal using npm run build:watch which will re-compile the code on change and cause the dynamodb-admin instance to restart.
