- Install dependencies:
$ cd deployingToHerokuWithPostgresqlAndKnex
$ npm install
$ createdb knex-heroku
$ touch .env
- Run the migration and seed files locally:
$ knex migrate:latest --env production
$ knex seed:run --env production
- Confirm thats all working by running nodemon and checking if 3 amphibians are rendered at localhost:3000
- Require the dotenv module at the top of your knexfile.js
require('dotenv').load();
module.exports = {
production: {
client: 'postgresql',
connection: 'postgres://localhost/knex-heroku',
pool : {
min: 2,
max: 10
}
}
};
- Now add the connection from your knexfile.js to your .env file as an environment variable called DATABASE_URL
//in the .env file
DATABASE_URL=postgres://localhost/knex-heroku
- Now you'll need to change your connection in your knexfile.js to use the environment variable
//knexfile.js
require('dotenv').load();
module.exports = {
production: {
client: 'postgresql',
connection: process.env.DATABASE_URL,
pool : {
min: 2,
max: 10
}
}
};
-
Good, now your database connection will be able to use either your local environment variable or the upcoming heroku database environment variable
-
Create a heroku app in the root directory of this exercise
$ heroku create
- Setup a remote heroku postgresql database with the free hobby-dev package
$ heroku addons:create heroku-postgresql:hobby-dev
- Push up your code to heroku
$ git add -A
$ git commit -m"ready for heroku"
$ git push heroku master
- Now run your migrations and your seeds via heroku
$ heroku run knex migrate:latest
$ heroku run knex seed:run
- Check your results
$ heroku open
- Congrats you have a remote heroku database !
- Get together with your team and deploy the application you made at Fridays Hackathon
