NestJs: Deploy to Heroku and Add Swagger Docs

#swagger #heroku #nestjs #nodej

Hello everyone, we'll be building on the puppies api. I strongly recommend you look at the previous post for the 🐶🐶🐶 puppies api.

Agenda

✅ Add Swagger Documentation
✅ Deploying to Heroku

Install the swagger docs and the types

Import the modules inside the main.ts file and configure it

Finally, add the `ApiProperty` to the Entities.

Let's test our documentation by running yarn start:dev and visiting localhost:7890/api/docs

Just to be sure our application still works, let's get all the puppies created.

Heroku Deployment

Create an app

Select overview and Configure Add Ons

Search for `Heroku postgres` and click

Submit the order form

Click on this to get redirected to the database dashboard

Click on the view credentials

Copy the Database Uri and Head to your `ormconfig.js file`

orm.config.js

require('dotenv').config();

module.exports = {
  url: process.env.DATABASE_URL,
  type: 'postgres',
  ssl: {
    rejectUnauthorized: false,
  },
  autoLoadEntities: true,
  synchronize: true,
  logging: true,
  entities: ['dist/**/*.entity.js'],
};

Of course, you don't want to hardcode your credentials. We store the Database in the .env file and imported in here.

Now for the actual deployment, follow these steps

One last thing to do is to add our env to Heroku's env variable
