Rust Crud api

Sample implementation of a rust web server using axum that integrates with posgresql and mongo db databases.

API Description

Exposes 2 separate crud implementations on /api/pg & /api/mongo for the PostgreSQL and MongoDB implementations respectively. You can list/create/update/delete customers by targeting the /api/pg path with attributes of customer_name & customer_surname in the request body. The same can be applied for MongoDB on the /api/mongo path.

Deployment

The application is packaged on a container for easy reuse on multiple environments. Liquibase is used for managing the PostgreSQL schema. The published containers exists here: https://hub.docker.com/repository/docker/konkerama/rust-crud-api

How to use

Prerquisites

Install rust on your system.

Test

cargo install sqlx-cli
./test.sh

Run API locally

docker compose up --build --force-recreate -V

docker compose performs the following steps:

• builds the container
• creates the mongodb and postgesql containers
• creates and runs the liquibase containers that configures the postgresql schema
• creates the pgadming and mongoexpress containers for easy debugging of the databases.

You can target the api using the following example curl commands:

# health check
curl http://localhost:8000/api/healthchecker -s | jq

# POST create customer 
curl -X POST http://localhost:8000/api/pg -d '{"customer_name": "john","customer_surname": "doe"}' -H "Content-Type: application/json" -s | jq

# GET customer (replace <id> with your customer id)
curl http://localhost:8000/api/pg/<id> -s | jq

# LIST customers
curl http://localhost:8000/api/pg -s | jq

# DELETE customer (replace <id> with your customer id)
curl -X DELETE http://localhost:8000/api/pg/<id> -s | jq

# PATCH customer (replace <id> with your customer id)
curl -X PATCH http://localhost:8000/api/pg/<id> -d '{"customer_name": "mark","customer_surname": "green"}' -H "Content-Type: application/json" -s | jq

# POST order
curl -X POST http://localhost:8000/api/mongo -d '{"customer_name":"mark", "product_name":"apple"}' -H "Content-Type: application/json" -s | jq

# LIST orders
curl http://localhost:8000/api/mongo -s | jq

# GET order (replace <id> with your order id)
curl http://localhost:8000/api/mongo/<id> -s | jq

# PATCH order (replace <id> with your order id)
curl -X PATCH http://localhost:8000/api/mongo/<id> -d '{"customer_name":"paul", "product_name":"banana"}' -H "Content-Type: application/json" -s | jq

# DELETE order (replace <id> with your order id)
curl -X DELETE http://localhost:8000/api/mongo/<id> -s | jq

Todo

• error handling using thiserror
• implement tracing using opentelemetry
