Clone this repo in order for you to follow this tutorial :
Now create a simple expressjs using the express command line like this :
mkdir opensource-marketplace-backend
cd opensource-marketplace-backend
npx express-generator
We gonna need to connect the database using postgresql so in order to do that we gonna use sequelize for that, run this command to do that :
npx sequelize init
When you do npx sequelize init you will see config/config.json file change that to config/config.js and add this code :
module.exports={
"development": {
"username": "panda",
"password": "panda1234",
"database": "panda_database",
"host": "127.0.0.1",
"dialect": "postgres"
},
"test": {
"username": "root",
"password": null,
"database": "database_test",
"host": "127.0.0.1",
"dialect": "mysql"
},
"production": {
"username": process.env.DB_USERNAME,
"password": process.env.DB_PASSWORD,
"database": process.env.DB_NAME,
"host": process.env.DB_HOST,
"port":process.env.DB_PORT,
"dialect": "postgres",
"dialectOptions": {
"ssl": { "require": true, "rejectUnauthorized": false }
}
}
}
If you see in production object i use ssl because in order for us to connect to app platform database later, we need that ssl, also i change all of the hardcoded username,password, etc. to environment variable to add more to the security, so you don't need to worry if your password got stolen coz when we put it to open source, it will be added in safe environment of app platform environment variable, now let's create a table for our apps :
npx sequelize model:create --name for_sell --attributes repo_id:string,description:string,name:string,openGraphImageUrl:string,url:string,isPrivate:boolean,username:string,sell:string,amount:string
npx sequelize model:create --name owned_repo --attributes repo_id:string,description:string,name:string,openGraphImageUrl:string,url:string,sell:string,amount:integer,owner_username:string,username:string
npx sequelize model:create --name paypal --attributes github_username:string,email:string,amount:integer,disconnect:boolean
npx sequelize model:create --name transaction --attributes random:string,for_sell_id:string,token:string
npx sequelize model:create --name user --attributes username:string, token:text, role:string
Now create a docker-compose.yml file and add this code:
version: '3'
services:
database:
image: "postgres"
ports:
- "5432:5432"
env_file:
- database.env
volumes:
- database-data:/var/lib/postgresql/data/
volumes:
database-data:
Run using docker-compose up -d then run npx sequelize db:migrate in order for you to create the table, now go to bin/www and change this line :
var port = normalizePort(process.env.PORT || '4000');
app.set('port', port);
This one will tell our app later to listen at port 4000 in app platform, now go to routes/index.js and change the code to this :
require("dotenv").config();

All of this is our main route in order for our application works, now we need to create all the logic create a folder called utils and add new file called authorize.js add this code :

If you have done all of that now create an .env file and write this :
frontend_url=<our static nuxtjs frontend url>
github_client_id=<github client id>
github_client_secret=<github client secret>
paypal_client_id=<paypal client id>
paypal_client_secret=<paypal client secret>
token_pass=<token pass for jwt>
return_url=<https://your_app_platform_url/manage-access>
cancel_url=<https://frontend_url/dashboard?cancel=message>
Now you've successfully create the backend of our app the step 3 would be to deploy this app into app platform
