About this API Reference
This reference guide describes the low-level service API for Amazon GameLift. With each topic in this guide, you can find links to language-specific SDK guides and the Amazon Web Services CLI reference. Useful links:
To install the this package, simply type add or install @aws-sdk/client-gamelift using your favorite package manager:
npm install @aws-sdk/client-gameliftyarn add @aws-sdk/client-gameliftpnpm add @aws-sdk/client-gamelift
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the GameLiftClient and
the commands you need, for example ListAliasesCommand:
// ES5 example
const { GameLiftClient, ListAliasesCommand } = require("@aws-sdk/client-gamelift");// ES6+ example
import { GameLiftClient, ListAliasesCommand } from "@aws-sdk/client-gamelift";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation on client with command object as input. - If you are using a custom http handler, you may call
destroy()to close open connections.
// a client can be shared by different commands.
const client = new GameLiftClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListAliasesCommand(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-gamelift";
const client = new AWS.GameLift({ region: "REGION" });
// async/await.
try {
const data = await client.listAliases(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listAliases(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listAliases(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;
* }
*/
