Programmers are already lazy enough. Typing extra text is not their thing. Less code with more benefits!

Programmers are aesthetes. The code must be lovely. Beautiful code is inexplicable and must be experienced.

We are programmers. And have done everything we could to make the JSight language concise and beautiful. And finally, it looks like we’ve got it!

For example, see what a simple API on JSight looks like:

JSIGHT 0.3

GET /cats/{id}
  200
    {
      "id"   : 123,   // {min: 0}
      "name" : "Tom"
    }

Any programmer, without requiring any explanation, will immediately and unmistakably understand what this API is about. Nothing superfluous! Every word, every letter has an important and precise sense.

Compare the same API on OpenAPI (Swagger):

openapi: 3.0.3
info:
  title: ""
  version: ""
paths:
  /cats/{id}:
    get:
      parameters:
      - name: id
        in: path
        required: true
        schema: {}
      responses:
        200:
          description: ""
          content:
            application/json:
              schema:
                type: object
                required: [id, name]
                properties:
                  id:
                    type: integer
                    minimum: 0
                    example: 123
                  name:
                    type: string
                    example: "Tom"

Doesn't this code seem redundant, to put it mildly?

We’re not criticizing OpenAPI. We’ve previously used it a lot and truly love it. But the world is moving forward and outdated technologies have to give way to new ones. It's time to move on to JSight, which is both concise and beautiful.

You can try out the JSight language right now: editor.jsight.io!

We’re starting a series of posts about the key features of the JSight language, which set it apart from all other API description languages and make describing API easier and faster.

Today, we’ll discuss the main feature, which we refer to as “Example as a schema”.

Any API description language describes data schemas in one way or another. For example, WSDL uses XSD to describe data, Blueprint API uses JSON Schema, and OpenAPI uses Schema Object.

The JSight API language uses the JSight Schema language to describe data. The JSight Schema approach, on the other hand, is fundamentally different from any other method of describing schemas. Now we'll tell you about this difference.

In 2020, Swagger interviewed over 3,000 IT specialists, asking them to name the top 5 most important things they seek in API documentation. What do you think the most popular ones were among the respondents? 70% of the respondents answered that they need EXAMPLES.

Unlike all other languages, the JSight Schema language primarily focuses on sample data. And this is completely justified. Programmers love examples! After all, most of the time, just looking at the example is enough to figure out what the data structure is.

In the JSight Schema language, the data example is already a data schema. For example, here is the simplest schema for you:

{
    "id": 123,
    "name": "Tom"
}

It is obvious from this schema that the data must be an object with an “id” property of type integer and a “name” property of type string. And if you need to add additional requirements to the schema that are not obvious from the sample data, then these requirements can be placed in a small JSON in the comments to the property:

{
    "id": 123, // {min: 1}
    "name": "Tom"
}

In the given diagram, it is added that the value of the “id" property must be greater than or equal to one.

For comparison, a similar schema in the OpenAPI language will look like this:

 type: object
 required: [id, name]
   properties:
     id:
       type: integer
       minimum: 1
       example: 123
     name:
       type: string
       example: "Tom"

Do you notice any differences?

On JSight, the schema is simpler, shorter and more appealing to the eye.
