nestjs-rest-api

NestJS Rest-Api powered by AWS RDS PostgreSQl

App Start

  1. Create .env file in the root and copy & paste mocked data from .sample-env
  2. Edit .env file by writing correct credentials and other connection data
  3. Run yarn start:dev (npm run start:dev) for development or yarn start (npm start) to up the server
  4. Connect to swagger using http://localhost:3000/docs url. Provide simple auth typing secret in x-auth-key input

Table updates

  1. Change any entity class and save file
  2. Run NAME=Init npm run generate-migration to generate a migration. Use custom names that are clear and correspond to table changes e.g. NAME=AddPhoneNumberColumnToUser npm run generate-migration
  3. Make sure the recently generated migration is in migrations folder
  4. Run npm run run-migration to apply migrations to the database
  5. If you want to revert a migration, run npm run revert-migration, but note: it cancels the last migration

If you make git clone or git pull in a project, you should run all migrations (if there are some changes in tables made by another dev) before development starting

Do not use TABLE_SCHEMA_AUTOUPDATE=true in prod

Deploy to EC2 instance

  1. Create an RDS Postgresql instance;
  2. Connect to RDS and create a database;
  3. Edit scripts/install_project_dependencies.sh by replacing your env variables;
  4. Create an EC2 instance based on Amazon Linux and provide this script to user data input while creation to install the CodeDeploy Agent:

#!/bin/bash
sudo yum -y update
sudo yum -y install ruby
sudo yum -y install wget
sudo wget https://aws-codedeploy-us-east-1.s3.amazonaws.com/latest/install
sudo chmod +x ./install
sudo ./install auto
