AWS SDK for JavaScript DatabaseMigrationService Client for Node.js, Browser and React Native.
Database Migration Service
Database Migration Service (DMS) can migrate your data to and from the most widely used commercial and open-source databases such as Oracle, PostgreSQL, Microsoft SQL Server, Amazon Redshift, MariaDB, Amazon Aurora, MySQL, and SAP Adaptive Server Enterprise (ASE). The service supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle to MySQL or SQL Server to PostgreSQL.
For more information about DMS, see What Is Database Migration Service? in the Database Migration Service User Guide.
To install the this package, simply type add or install @aws-sdk/client-database-migration-service using your favorite package manager:
npm install @aws-sdk/client-database-migration-serviceyarn add @aws-sdk/client-database-migration-servicepnpm add @aws-sdk/client-database-migration-serviceThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the DatabaseMigrationServiceClient and
the commands you need, for example ListTagsForResourceCommand:
// ES5 example
const {
DatabaseMigrationServiceClient,
ListTagsForResourceCommand,
} = require("@aws-sdk/client-database-migration-service");
// ES6+ example
import { DatabaseMigrationServiceClient, ListTagsForResourceCommand } from "@aws-sdk/client-database-migration-service";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by different commands.
const client = new DatabaseMigrationServiceClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListTagsForResourceCommand(params);
We recommend using await operator to wait for the promise returned by send operation as follows:
// async/await.
try {
const data = await client.send(command);
// process data.
} catch (error) {
// error handling.
} finally {
// finally.
}
Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);
Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// process err and data.
});
The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-database-migration-service";
const client = new AWS.DatabaseMigrationService({ region: "REGION" });
// async/await.
try {
const data = await client.listTagsForResource(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listTagsForResource(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listTagsForResource(params, (err, data) => {
// process err and data.
});
When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).
try {
const data = await client.send(command);
// process data.
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
/**
* The keys within exceptions are also parsed.
* You can access them by specifying exception names:
* if (error.name === 'SomeServiceException') {
* const value = error.specialKeyInException;
* }
*/
}
