Utilities for OAuth authentication using
NASA Earthdata Login and AWS Cognito.Versioning
Cumulus uses a modified semantic versioning scheme and minor releases likely include breaking changes.Before upgrade, please read the Cumulus release notes before upgraded.
It is strongly recommended you do not use
^
in your package.json
to
automatically update to new minor versions. Instead, pin the version or use ~
to automatically update to new patch versions.Installation
$ npm install @cumulus/oauth-client
Class Structure
This package contains a generic, parent class calledOAuthClient
. This class has a few common methods
like oAuthClient.getAuthorizationUrl()
which are used by all classes that inherit from OAuthClient
.The examples below document these common methods as well as methods specific to the child classes, e.g.
cognitoClient.getUserInfo(accessToken)
.Earthdata Login Usage Example
const { EarthdataLoginClient } = require('@cumulus/oauth-client');
const client = new EarthdataLogin({
clientId: 'my-client-id',
clientPassword: 'my-client-password',
loginUrl: 'https://earthdata.login.nasa.gov',
redirectUri: 'http://my-api.com'
});
Cognito Usage Example
const { CognitoClient } = require('@cumulus/oauth-client');
const client = new CognitoClient({
clientId: 'my-client-id',
clientPassword: 'my-client-password',
loginUrl: 'https://auth.csdap.sit.earthdatacloud.nasa.gov/',
redirectUri: 'http://my-api.com'
});
