Function createCredentialChain

Example

import { fromEnv, fromIni, createCredentialChain } from '@ibm-cos/credential-providers';
import { S3 } from 'ibm-cos-sdk-v2';

// You can mix existing AWS SDK credential providers
// and custom async functions returning credential objects.
new S3({
  credentials: createCredentialChain(
    fromEnv(),
    async () => {
      // credentials customized by your code...
      return credentials;
    },
    fromIni()
  ),
});

// Set a max duration on the credentials (client side only).
// A set expiration will cause the credentials function to be called again
// when the time left is less than 5 minutes.
new S3({
  // expire after 15 minutes (in milliseconds).
  credentials: createCredentialChain(fromEnv(), fromIni()).expireAfter(15 * 60_000),
});

// Apply shared init properties.
const init = { logger: console };

new S3({
  credentials: createCredentialChain(fromEnv(init), fromIni(init)),
});
