Serverless-AWS-Lambda-Node-Express-MongoDB Boilerplate🚀

Boilerplate for Creating Restful API using Express.js, Node.js, MongoDB and Setting up on AWS Lambda

• 🚀Star on Github

• Prerequisites

  • AWS IAM Role
  • Mongodb Atlas Cloud
  • Serverless Framework
  • Node.js
  • Express.js
  • Mongodb
  • body-parser
  • Serverless-offline
  • loadtest

Installation Steps

In the root directory run the following command:

• npm install It will save all the dependencies and dev-dependencies present in package.json

Setup the IAM Role and configure the serverless(sls) command line.

Create an account on Mongodb Atlass Cloud and Whitelist the IP Address 0.0.0.0/0. Also create a user in database and setup it in secrets.json

Create Restful API using Express and Node

Deploy the codebase using

sls deploy

for the development stage
For production switch over to

production

in secrets.json

After

sls deploy

. Code will be deployed on AWS Lambda. Head over to AWS Lambda and test it using Postman or Insomnia. After that for scaling test, use

loadtest

and send 100 GET concurrent requests for 10 simulatenous users and watch the latency that comes around to be ~5 seconds.

Cheers! AWS Lambda Auto Scaling with an increase in requests.
