diesel

Basic integration of Diesel using SQLite for Actix web.

Usage

Install SQLite

# on OpenSUSE
sudo zypper install sqlite3-devel libsqlite3-0 sqlite3

# on Ubuntu
sudo apt-get install libsqlite3-dev sqlite3

# on Fedora
sudo dnf install libsqlite3x-devel sqlite3x

# on macOS (using homebrew)
brew install sqlite3

Initialize SQLite Database

cd examples/diesel
cargo install diesel_cli --no-default-features --features sqlite

echo "DATABASE_URL=test.db" > .env
diesel migration run

There will now be a database file at ./test.db.

Running Server

cd examples/diesel
cargo run (or ``cargo watch -x run``)

# Started http server: 127.0.0.1:8080

Available Routes

POST /user

Inserts a new user into the SQLite DB.

Provide a JSON payload with a name. Eg:

{ "name": "bill" }

On success, a response like the following is returned:

{
    "id": "9e46baba-a001-4bb3-b4cf-4b3e5bab5e97",
    "name": "bill"
}

Client Examples

Using HTTPie:

http POST localhost:8080/user name=bill

Using cURL:

curl -S -X POST --header "Content-Type: application/json" --data '{"name":"bill"}' http://localhost:8080/user

GET /user/{user_uid}

Gets a user from the DB using its UID (returned from the insert request or taken from the DB directly). Returns a 404 when no user exists with that UID.

http localhost:8080/user/9e46baba-a001-4bb3-b4cf-4b3e5bab5e97
