Guide: how to read mertozen.com from start to finish

The series on this site are read stage by stage, from the basics to advanced topics, around a single sample application called Bookstore. This page shows where to start, which series to read after which, and where to find each series' code on GitHub.

If your goal is clear, pick one of the paths below; the map then highlights only that path's series. If you are not sure, start with Stage 0 and follow the order. Skipping is fine: each series card lists the series worth reading first.

What is Bookstore?

Bookstore is an online bookstore. Every series on the site covers a different side of this one product: the data model, the API, the Angular UI, security, deployment and the team's process. What you learn in one series builds on the same application in the next.

Product: book sales to individual customers (catalog, search, cart, orders, payment, shipping, returns, campaigns), Institutional Orders for schools, libraries and companies, and a back office for stock, purchasing and reports.
Modules: Catalog, Ordering, Inventory, Payments, Shipping, Notifications, Institutional, Identity.
Tech: Bookstore.Api (ASP.NET Core Web API) with .NET 10 and C#, SQL Server through EF Core, and bookstore-web with Angular 22.
Team: the process series follow the same team: Selin (Product Owner), Emre and Ayşe (developers), Hakan (institutional sales), Gül (customer service) and the institutional customer Nevin Hanım.

Where is the code? GitHub guide

All the code lives in a single GitHub repository. The layout is simple: one branch per series, one tag per post.

Branch: series/<series-slug>. Example: series/docker, the final state of the Docker series.
Tag: <series-slug>/NN. Example: docker/05, the code as it was at the end of post 05 of the Docker series.
Reference application: the main branch.

git clone https://github.com/mrtozn1923/bookstore.git
cd bookstore
git switch series/docker        # final state of the series
git switch --detach docker/05   # code of post 05

Concept-heavy series (process, architecture concepts and the like) have no separate code; on the map the GitHub link appears only for series that have a branch.

Open the repository on GitHub

Where should I start?

Pick the path that fits your goal; the map highlights only that path's series.

Map: the reading order stage by stage

Read the stages top to bottom. At stage 4 the map splits into three independent branches.

Frequently asked questions

I know nothing yet. Where do I start?

Start with Stage 0: set up your environment, get to know Bookstore and learn Git. Then follow the stages in order. Each stage starts with a note on why it is there.

Can I skip ahead?

Yes. The series are written to be readable on their own. Each series card lists the series worth reading first as prerequisites; if you already know them, go straight on.

Should I read the backend or the frontend branch first?

After Stage 3 the map splits into three branches: backend, frontend and data. They are independent; pick one for your goal or move through them in parallel. The full-stack path includes both.

How do I run Bookstore on my machine?

Clone the repository and switch to the tag of the post you are reading (for example git switch --detach docker/05). The setup is described in the first post of each series and in the repository README.

Why is each post's code in a separate tag?

So you see the code exactly as it was while reading the post. Later posts' changes don't get mixed in, and comparing two tags shows what a post changed.

When should I read the AI series?

To use AI tools (Claude, ChatGPT, Copilot) you can start right after Stage 0. To add an LLM to your own application (Claude API, RAG, agents), knowing the API series in Stage 3 first makes it easier.
