@aws-rum/web-slim

A smaller, imperative distribution of the Amazon CloudWatch RUM web client. Same AwsRum class and public API as aws-rum-web — without bundled Cognito auth, default telemetries, remote config, or SigV4 signing. You wire those up yourself, so you pay only for what you import.

Documentation

Start at docs/README.md for the full index. Slim-specific entry points:

• Full → slim migration guide — step-by-step if you're coming from aws-rum-web
• Packages overview — slim vs full vs core
• Configuration reference
• Auth concepts — resource-policy flow pairs naturally with slim

Quick start

1. Create an app monitor. Follow Set up an app monitor in the CloudWatch RUM user guide.

2. Install and initialize.

npm install @aws-rum/web-slim

import {
    AwsRum,
    AwsRumConfig,
    FetchPlugin,
    JsErrorPlugin
} from '@aws-rum/web-slim';

const config: AwsRumConfig = {
    sessionSampleRate: 1,
    endpoint: 'https://dataplane.rum.us-west-2.amazonaws.com',
    eventPluginsToLoad: [new FetchPlugin(), new JsErrorPlugin()],
    allowCookies: true
};

const awsRum = new AwsRum('application-id', '1.0.0', 'us-west-2', config);

Note: no identityPoolId, no telemetries, no signing: true. Every other field of AwsRumConfig behaves the same as the full build.
