Usage / API

Yay's API supports filtering, sorting and paginating for GET requests.

Automatically-generated API documentation can be found at http://localhost:50080/api/doc, run it with make start. The latest stable version https://yay-demo.sloppy.zone/api/doc is available via sloppy.io.

Filtering results

Filtering for specific results is achieved by the filter query parameter.

Filter by name, it must equal Alex Doe:

curl -gX "GET" http://localhost:50080/api/players/?filter[name]=Jane+Doe
// Same as: curl -gX "GET" http://localhost:50080/api/players/?filter[name:eq]=Jane+Doe

[
    {
        "name": "John Doe",
        "username": "john.doe",
        "created_at": "2018-01-02T13:24:40+00:00",
    },
    {
        "name": "Alex Doe",
        "username": "alex.doe",
        "created_at": "2018-01-02T13:24:19+00:00",
    }
]

Supported filter methods:

The filtering uses a specific syntax to enable different types of matching strategies: filter[$field:$expression]=$value.

Expression Example Description
* filter[name]=Jane+Doe Value of field name equals Alex Doe.
eq filter[name:eq]=Jane+Doe Value of field name equals Alex Doe.
gt filter[score:gt]=10 Value of field name is greater than 10.
lt filter[score:lt]=10 Value of field name is less than 10.
lte filter[score:lte]=10 Value of field name is greater than or equals 10.
gte filter[score:gte]=10 Value of field name is less than or equals 10.
neq filter[name:neq]=Jane+Doe Value of field name does not equal Alex Doe.
contains filter[name:contains]=Doe Value of field name contains Doe.
startsWith filter[name:startsWith]=Jane Value of field name ends with Jane.
endsWith filter[name:endsWith]=Doe Value of field name ends with Doe.

Sorting results

Setting a sorting is possible through setting a order query parameter. Sorting both ascending and descending is possible.

Sorts by field created_at, use default sort direction (desc):

curl -gX "GET" http://localhost:50080/api/players/?order[created_at]

[
    {
        "name": "John Doe",
        "username": "john.doe",
        "created_at": "2018-01-02T13:24:40+00:00",
    },
    {
        "name": "Alex Doe",
        "username": "alex.doe",
        "created_at": "2018-01-02T13:24:19+00:00",
    }
]

Sorts by field created_at, use ascending as sort direction (asc):

curl -gX "GET" http://localhost:50080/api/players/?order[created_at]=asc

[
    {
        "name": "Alex Doe",
        "username": "alex.doe",
        "created_at": "2018-01-02T13:24:19+00:00",
    },
    {
        "name": "John Doe",
        "username": "john.doe",
        "created_at": "2018-01-02T13:24:40+00:00",
    }
]

Paginating results

Paginating through results is possible by using the limit and offset query parameters.

Shows the first result:

curl -gX "GET" http://localhost:50080/api/players/?limit=1

[
    {
        "name": "Alex Doe",
        "username": "alex.doe",
        "created_at": "2018-01-02T13:24:19+00:00",
    }
]

Shows the second result:

curl -gX "GET" http://localhost:50080/api/players/?limit=1&offset=1

[
    {
        "name": "John Doe",
        "username": "john.doe",
        "created_at": "2018-01-02T13:24:40+00:00",
    }
]

Demo

To run the demo we need to enable the demo integration. You can do so by using the built-in make command make enable-demo for your local dev environment or executing the appropriate console command (php bin/console yay:integration:enable demo integration/demo), we choose the former.

$ make enable-demo

[OK] Integration "default" enabled
[OK] Integration "demo" enabled

Now we can run the application.

$ make start
# ...
# http://localhost:50080

1) Make a request to localhost:50080/api/players.

curl -X "GET" http://localhost:50080/api/players/

[]

There are no users created yet, let's create a user by executing the following request.

curl -X POST http://localhost:50080/api/players/ \
    -d "{\"name\": \"Alex Doe\",\"username\":\"alex.doe\",\"email\": \"[email protected]\",\"image_url\":\"https://avatars.dicebear.com/v2/female/354.svg\"}"

{
    "name": "Alex Doe",
    "username": "alex.doe",
    "image_url": "https://avatars.dicebear.com/v2/female/354.svg",
    "score": 0,
    "links": {
        "self": "http://localhost:50080/api/players/alex.doe/",
        "personal_achievements": "http://localhost:50080/api/players/alex.doe/personal-achievements/",
        "personal_actions": "http://localhost:50080/api/players/alex.doe/personal-actions/"
    }
}

2) Make a request to localhost:50080/api/actions. Here you can see a list of available actions a user can perform. Let us pickdemo-action-01.

curl -X "GET" http://localhost:50080/api/actions/

[
    {
        "name": "demo-action-01",
        "label": "Accusamus molestias eum libero ullam libero.",
        "links": {
            "self": "http://localhost:50080/api/actions/demo-action-01/"
        }
    }
]

3) Make a request to localhost:50080/api/achievements. Here you can see a list of available achievements, in this demo you can earn both achievements by performing 5x the action demo-action-01 for the first achievement and then 10x the action demo-action-01 for the second achievement.

curl -X "GET" http://localhost:50080/api/achievements/

[
    {
        "name": "demo-achievement-01",
        "label": "Facere quibusdam iure voluptas velit sapiente.",
        "description": "Facere quibusdam iure voluptas velit sapiente.",
        "points": 50,
        "image_url": "https://avatars.dicebear.com/v2/identicon/demo-achievement-01.svg",
        "links": {
            "self": "http://localhost:50080/api/achievements/demo-achievement-01/",
            "actions": [
                "http://localhost:50080/api/actions/demo-action-01/"
            ]
        }
    },
    {
        "name": "demo-achievement-02",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "points": 50,
        "image_url": "https://avatars.dicebear.com/v2/identicon/demo-achievement-02.svg",
        "links": {
            "self": "http://localhost:50080/api/achievements/demo-achievement-02/",
            "actions": [
                "http://localhost:50080/api/actions/demo-action-01/"
            ]
        }
    }
]

4) Let our player alex.doe perform the action demo-action-01 one time.

curl -X POST http://localhost:50080/api/progress/ \
    -d "{\"username\":\"alex.doe\",\"action\":\"demo-action-01\"}"

[]

No achievements were granted yet, although if you check now our players personal actions you will find our recent action.

curl -X "GET" http://localhost:50080/api/players/alex.doe/personal-actions/

[
    {
        "name": "demo-action-01",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "achieved_at": "2017-10-08T12:48:13+0000",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/personal-actions/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "action": "http://localhost:50080/api/actions/demo-action-01/"
        }
    }
]

If you're curious to see how far our player progress towards an achievement, you can query transient achievements.

curl -X "GET" http://localhost:50080/api/players/alex.doe/transient-achievements/

[
    {
        "name": "demo-achievement-01",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "progress": 20,
        "points": 50,
        "image_url": "https://avatars.dicebear.com/v2/identicon/demo-achievement-01.svg",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/transient-actions/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "achievement": "http://localhost:50080/api/achievements/demo-achievement-01/"
        }
    }
]

Now let us get our first achievement. For this, perform the demo.action action four more times.

curl -X POST http://localhost:50080/api/progress/ \
    -d "{\"username\":\"alex.doe\",\"actions\":[\"demo-action-01\",\"demo-action-01\",\"demo-action-01\",\"demo-action-01\"]}"

[
    {
        "name": "demo-achievement-01",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "points": 50,
        "achieved_at": "2017-10-08T13:22:08+0000",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/personal-achievements/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "achievement": "http://localhost:50080/api/achievements/demo-achievement-01/"
        }
    }
]

Et voilà: we earned our first achievement!

5) Now let's go further. Let the player perform the demo-action-01 action five more times.

curl -X POST http://localhost:50080/api/progress/ \
    -d "{\"username\":\"alex.doe\",\"actions\":[\"demo-action-01\",\"demo-action-01\",\"demo-action-01\",\"demo-action-01\",\"demo-action-01\",\"demo-action-01\"]}"

[
    {
        "name": "demo-achievement-02",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "points": 50,
        "achieved_at": "2017-10-08T13:23:53+0000",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/personal-achievements/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "achievement": "http://localhost:50080/api/achievements/demo-achievement-02/"
        }
    }
]⏎

Clap, clap! Our player earned their second official achievement.

6) Let's check our player achievements by performing the following request.

curl -X "GET" http://localhost:50080/api/players/alex.doe/personal-achievements/

[
    {
        "name": "demo-achievement-01",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "points": 50,
        "achieved_at": "2017-10-08T13:22:08+0000",
        "image_url": "https://avatars.dicebear.com/v2/identicon/demo-achievement-02.svg",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/personal-achievements/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "achievement": "http://localhost:50080/api/achievements/demo-achievement-01/"
        }
    },
    {
        "name": "demo-achievement-02",
        "label": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "description": "Nulla soluta iusto recusandae est veritatis nesciunt sequi.",
        "points": 50,
        "achieved_at": "2017-10-08T13:23:53+0000",
        "image_url": "https://avatars.dicebear.com/v2/identicon/demo-achievement-02.svg",
        "links": {
            "self": "http://localhost:50080/api/players/alex.doe/personal-achievements/",
            "player": "http://localhost:50080/api/players/alex.doe/",
            "achievement": "http://localhost:50080/api/achievements/demo-achievement-02/"
        }
    }
]

And that's all for the demo. Yay!
