-## [dbManager](/src/middlewares/dbManager.js)
-
-dbManager provides seamless connection with database of your choice. By default it uses knex.js but you can use any tool that you want.
-
-After initialization your database connection is accessible under:
-```javascript
-middy((event, context) => {
-  const { db } = context;
-});
-```
-
-Mind that if you use knex you will also need driver of your choice ([check docs](http://knexjs.org/#Installation-node)), for PostgreSQL that would be:
-```
-yarn add pg
-// or
-npm install pg
-```
-
-### Options
-
-- `config`: configuration object passed as is to client (knex.js by default), for more details check [knex documentation](http://knexjs.org/#Installation-client)
-- `client` (optional): client that you want to use when connecting to database of your choice. By default knex.js is used but as long as your client is run as `client(config)` or you create wrapper to conform, you can use other tools. Due to node6 support in middy, knex is capped at version `0.17.3`. If you wish to use newer features, provide your own knex client here.
-- `secretsPath` (optional): if for any reason you want to pass credentials using context, pass path to secrets laying in context object  - good example is combining this middleware with [ssm](#ssm)
-- `removeSecrets` (optional): By default is true. Works only in combination with `secretsPath`. Removes sensitive data from context once client is initialized.
-- `forceNewConnection` (optional): Creates new connection on every run and destroys it after. Database client needs to have `destroy` function in order to properly clean up connections.

-### Sample usage
-
-Minimal configuration
-
-```javascript
-const handler = middy(async (event, context) => {
-  const { db } = context;
-  const records = await db.select('*').from('my_table');
-  console.log(records);
-});
-
-handler.use(dbManager({
-  config: {
-    client: 'pg',
-    connection: {
-      host: '127.0.0.1',
-      user: 'your_database_user',
-      password: 'your_database_password',
-      database: 'myapp_test'
-    }
-  },
-}));
-```
-
-Credentials as secrets object
-
-```javascript
-const handler = middy(async (event, context) => {
-  const { db } = context;
-  const records = await db.select('*').from('my_table');
-  console.log(records);
-});
-
-handler.use(secretsManager({
-    secrets: {
-        [secretsField]: 'my_db_credentials' // { user: 'your_database_user', password: 'your_database_password' }
-    },
-    throwOnFailedCall: true
-}));
-
-handler.use(dbManager({
-  config: {
-    client: 'pg',
-    connection: {
-      host : '127.0.0.1',
-      database : 'myapp_test'
-    }
-  },
-  secretsPath: secretsField
-}));
-```
