​

Repository Overview

Postiz is an open-source project, and the source code is available on GitHub. The project is generally built using scripts in the package.json file with npm. The main scripts are:

• npm run dev - Starts the development server
• npm run prisma-generate - Generates the Prisma client
• npm run prisma-db-push - Pushes the database schema to the database

The entire project is built under NX to have a monorepo with multiple projects. Unlike other NX project, this project has one .env file that is shared between all the apps. It makes it easier to develop and deploy the project.

​

Frontend

The frontend is built with NextJS and TailwindCSS.

​

Backend

The backend is built with NestJS with a basic architecture of controllers, services, repositories and dtos. It uses Prisma as an ORM to interact with the database. By default Prisma uses Postgres as a database, but it can be easily changed to any other database since there are no native queries. It uses Redis to schedule posts and run background jobs.

​

Cron

cron is built with NestJS and share components with the backend.

​

Worker

worker is built with NestJS and share components with the backend.
