Devagram

An instagram infra abstraction created with a serverless architecture.

Tech stack

• Serverless framework
• Node.js
• Typescript
• AWS (DynamoDB, S3, Lambda, Cognito)

Commands

• sls deploy to deploy changes to AWS and get the list of endpoints created.

Command Params

• --region {name} sets the regions in which the infra will deploy.
• --stage {name} sets the stage environment. ie: dev, dev2, hml, prod etc.
• --param="level={levelName} sets the level of logs which should log on CloudWatch.

API

• Endpoints are created in src/functions folder. each function, in each file, is a different endpoint.
• The API configuration is on serverless.yml file, on functions block.

Testing the API

• I'm using Hoppscotch to test the API, making simple requests adding data manually.

Logs

• I'm using Winston to manage logs with logs levels. As you can see in serverless.yml file, there is a cli param called level (--param="level={levelName}") where you can inform which log level you want, setting an ENV variable. So info and debug logs will only display if the ENV variable is set to do so, making the logs organized by the log levels you want.
