Supply Chain Management System Backend (API)

Smart supply chain management system for Bangladesh specifically. The project includes:

• API Backend in NESTJS
• Frontend in NEXTJS
• Database using Postgres

I am leaving the project & so from now on the project is open for contributions. If you want to contribute, please open an issue first and then create a pull request. I will review the pull request and merge it if it is good.

Description

The project targets to create a REST API for a Smart Supply Chain Management System. The API is built using NestJS and PostgreSQL.

Notes

• The authentication has been disabled willingly for the purpose of making it work with the frontend as the frontend is kinda incomplete. So the API is not secure at the moment. It is recommended to enable authentication before deploying it to production. Can be enabled in this file logistics/logistics.controller.ts by adding @UseGuards(SessionGuard) to the routes.

• In order to run the API, you need to have a PostgreSQL database running. The database configuration can be found in the .env file. If the file does not exist, create one and add the told variables in the Configuring the database section below. The database has to be created manually. The tables will be created automatically by the API.

• The project is not fully complete so there might be some bugs. If you find any, please open an issue or contribute as I am leaving this project for now.

Test Using Curl

Take any API route and use curl to test it. For example:

curl -X GET localhost:3000/logistics/shipments | jq .

I have used jq to format the output. You need to install it first.
