+# diesel
+
+Basic integration of [Diesel-async](https://github.com/weiznich/diesel_async) using PostgreSQL for Actix Web.
+
+## Usage
+
+### Install PostgreSQL
+
+```sh
+# on any OS
+docker run -d --restart unless-stopped --name postgresql -e POSTGRES_USER=test-user -e POSTGRES_PASSWORD=password -p 5432:5432 -v postgres_data:/var/lib/postgresql/data postgres:alpine
+```
+
+### Initialize PostgreSQL Database
+
+```sh
+cd databases/diesel-async
+cargo install diesel_cli --no-default-features --features postgres
+
+echo DATABASE_URL=postgres://test-user:password@localhost:5432/test_db > .env
+diesel setup
+diesel migration run
+```
+
+The database will now be created in your PostgreSQL instance.
+```sh
+docker exec -i postgresql psql -U test-user -c "\l"
+```
+
+### Running Server
+
+```sh
+cd databases/diesel-async
+cargo run
+
+# Started http server: 127.0.0.1:8080
+```
+
+### Available Routes
+
+#### `POST /item`
+
+Inserts a new item into the PostgreSQL DB.
+
+Provide a JSON payload with a name. Eg:
+
+```json
+{ "name": "bill" }
+```
+
+On success, a response like the following is returned:
+
+```json
+{
+  "id": "01948982-67d0-7a55-b4b1-8b8b962d8c6b",
+  "name": "bill"
+}
+```
+
+<details>
+  <summary>Client Examples</summary>
+
+Using [HTTPie]:
+
+```sh
+http POST localhost:8080/item name=bill
+```
+
+Using cURL:
+
+```sh
+curl -S -X POST --header "Content-Type: application/json" --data '{"name":"bill"}' http://localhost:8080/item
+```
+
+</details>
+
+#### `GET /item/{item_uid}`
+
+Gets an item from the DB using its UID (returned from the insert request or taken from the DB directly). Returns a 404 when no item exists with that UID.
+
+<details>
+  <summary>Client Examples</summary>
+
+Using [HTTPie]:
+
+```sh
+http localhost:8080/item/9e46baba-a001-4bb3-b4cf-4b3e5bab5e97
+```
+
+Using cURL:
+
+```sh
+curl -S http://localhost:8080/item/9e46baba-a001-4bb3-b4cf-4b3e5bab5e97
+```
+
+</details>
+
+### Explore The PostgreSQL DB
+
+```sh
+docker exec -i postgresql psql -U test-user -d test_db -c "select * from public.items"
+```
+
+## Using Other Databases
+
+You can find a complete example of Diesel + PostgreSQL at: [https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/Rust/actix](https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/Rust/actix)
