You can read the documentation at: https://middy.js.org/docs/middlewares/secrets-manager

This middleware fetches secrets from AWS Secrets Manager.

Secrets to fetch can be defined by by name. See AWS docs here.

Secrets are assigned to the function handler's context object.

The Middleware makes a single API request for each secret as Secrets Manager does not support batch get.

For each secret, you also provide the name under which its value should be added to context.

Install

To install this middleware you can use NPM:

npm install --save @middy/secrets-manager

Options

  • AwsClient (object) (default AWS.SecretsManager): AWS.SecretsManager class constructor (e.g. that has been instrumented with AWS XRay). Must be from aws-sdk v2.
  • awsClientOptions (object) (default undefined): Options to pass to AWS.SecretsManager class constructor.
  • awsClientAssumeRole (string) (default undefined): Internal key where secrets are stored. See @middy/sts on to set this.
  • awsClientCapture (function) (default undefined): Enable XRay by passing captureAWSClient from aws-xray-sdk in.
  • fetchData (object) (required): Mapping of internal key name to API request parameter SecretId.
  • disablePrefetch (boolean) (default false): On cold start requests will trigger early if they can. Setting awsClientAssumeRole disables prefetch.
  • cacheKey (string) (default secrets-manager): Cache key for the fetched data responses. Must be unique across all middleware.
  • cacheExpiry (number) (default -1): How long fetch data responses should be cached for. -1: cache forever, 0: never cache, n: cache for n ms.
  • setToContext (boolean) (default false): Store secrets to request.context.

NOTES:

  • Lambda is required to have IAM permission for secretsmanager:GetSecretValue

Sample usage

import middy from '@middy/core'
import secretsManager from '@middy/secrets-manager'

const handler = middy((event, context) => {
  return {}
})

handler.use(secretsManager({
  fetchData: {
    apiToken: 'dev/api_token'
  },
  awsClientOptions: {
    region: 'us-east-1',
  },
  setToContext: true,
}))

// Before running the function handler, the middleware will fetch from Secrets Manager
handler(event, context, (_, response) => {
  // assuming the dev/api_token has two keys, 'Username' and 'Password'
  t.is(context.apiToken.Username,'username')
  t.is(context.apiToken.Password,'password')
})
