Boilerplate for Creating Restful API using Express.js, Node.js, Mongodb and Setting up on AWS Lambda
-
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) commandline.
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 increase in requests.
