Auth microservice

An example of Auth microservice using Node.js, Serverless framework, and Mongo.DB.

How to deploy?

Make sure serverless framework is installed:

  yarn global add serverless

Install dependencies:

  yarn install

Configure .env with JWT Secret and MongoDB URI (you can use MongoDB Atlas):

MONGODB_URI=<MY_URI>
JWT_SECRET=<MY_SECRET>

Configure serverless framework with AWS access key and secret:

  serverless config credentials --provider aws --key <ID> --secret <SECRET> --profile devProfile

Deploy:

  serverless deploy

There are many ways to create protected serverless functions. To see more about serverless auth, read this;
Mongoose recommendations for Lambda functions: https://mongoosejs.com/docs/lambda.html;
MongoDB guidelines for Serverless: https://www.mongodb.com/blog/post/serverless-development-with-nodejs-aws-lambda-mongodb-atlas;
I took as guide this walkthrough to understand and apply authentication in Node.js microservices;

Include customAuthorizer in verifyAuth function (https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-use-lambda-authorizer.html);
Verify if user is already registered on sign up;
Write tests for microservice;
Write endpoint documentations in README.md;
Include cors middleware in middy handler.

This is my first microservice using AWS Lambda 😉. Please feel free to contribute, forking this repository, and sending your pull request
