How to use

First, setup your client in a dedicated module:

// client.jsimportcreateClientfrom'serverless-pg';constdbClient=createClient({config: {host: process.env.HOST,port: process.env.PORT,user: process.env.USERNAME,password: process.env.PASSWORD,database: process.env.NAME,},onConnect: ()=>{},onClose: ()=>{},beforeQuery: ()=>{},afterQuery: ()=>{},});exportdefaultdbClient;

Then, import anywhere in your application and use.

// handler.jsimportdbClientfrom'./client';consthandler=async()=>{// calling query automagically connects to the databaseawaitdbClient.query('SELECT * FROM users');awaitdbClient.transaction([()=>dbClient.query(''),()=>dbClient.query('')]);awaitdbClient.end();};
