|

This repository serves as supplementary material for [the book](https://zero2prod.com/): it hosts snapshots of the codebase of our email newsletter project at end of each chapter.
|
||||
|
||||
It is structured as a `cargo` workspace: running `cargo build` will build the codebase for **all** chapters.
|
||||
If you want to build/test/run the code for a _specific_ chapter, just move into its folder! E.g.:
|
||||
## Chapter snapshots
|
||||
|
||||
The `master` branch (where you are right now!) shows the project at the end of the last published chapter _(Chapter 5, right now)_.
|
||||
|
||||
You can browse the project at end of previous chapters by switching to their dedicated branches:
|
||||
|
||||
- [Chapter 3, Part 0](https://github.com/LukeMathWalker/zero-to-production/tree/root-chapter-03-part0)
|
||||
- [Chapter 3, Part 1](https://github.com/LukeMathWalker/zero-to-production/tree/root-chapter-03-part1)
|
||||
- [Chapter 4](https://github.com/LukeMathWalker/zero-to-production/tree/root-chapter-04)
|
||||
- [Chapter 5](https://github.com/LukeMathWalker/zero-to-production/tree/root-chapter-05)
|
||||
|
||||
## Pre-requisite
|
||||
|
||||
You'll need to install:
|
||||
|
||||
- [Rust](https://www.rust-lang.org/tools/install)
|
||||
- [Docker](https://docs.docker.com/get-docker/)
|
||||
|
||||
Launch a (migrated) Postgres database via Docker:
|
||||
|
||||
```bash
|
||||
# Run tests for the first part of Chapter 3
|
||||
cd chapter03-0
|
||||
cargo test
|
||||
./scripts/init_db.sh
|
||||
```
|
||||
Alternatively, from the top-level folder, you can specify the binary you are interested into:
|
||||
|
||||
## How to build
|
||||
|
||||
Using `cargo`:
|
||||
|
||||
```bash
|
||||
# Run the application as it is at end of the first part of Chapter 3
|
||||
cargo run --bin chapter03-0
|
||||
cargo build
|
||||
```
|
||||
|
||||
## How to test
|
||||
|
||||
Using `cargo`:
|
||||
|
||||
```bash
|
||||
cargo test
|
||||
```
