  • How to use Axe API client?
  • What is the active record pattern?

Axe API Client ​

You can always fetch data from Axe API by sending a simple HTTP request by your favorite tools such as fetch or axios.

We created another tool which is called axe-api-client that you can use. axe-api-client is a tool specified for Axe API servers, and designed on the Active Record Pattern.

You can use the Axe API Client in both frontend and backend projects.

Installation ​

You can use the following command to add axe-api-client library to your project.

bash
$ npm install axe-api-client

Configuration ​

You can set the basic settings like the following example:

ts
import api, { IRequest } from "axe-api-client";

api.setConfig({
  baseURL: "https://your-domain.com/api/v1",
  headers: {
    "x-my-common-header": "my-value",
  },
  params: {},
});

Inserting data ​

You can use the following example to send an insert request to an Axe API server.

ts
const response = await api.resource("users").insert({
  name: "Karl",
  surname: "Popper",
});
bash
$ curl \
  -d '{"name":"Karl","surname":"Popper"}' \
  -H "Content-Type: application/json" \
  -X POST https://your-domain.com/api/v1/users
json
{
  "id": 1,
  "name": "Karl",
  "surname": "Popper"
}

Update ​

You can use the following example to update a record.

ts
const response = await api.resource("users/1").update({
  name: "Karl",
  surname: "Popper",
});
bash
$ curl \
  -d '{"name":"John","surname":"Locke"}' \
  -H "Content-Type: application/json" \
  -X PUT https://your-domain.com/api/v1/users/1
json
{
  "id": 1,
  "name": "John",
  "surname": "Locke"
}

Patch ​

You can use the following example to patch a record.

ts
const response = await api.resource("users/1").patch({
  surname: "Popper",
});
bash
$ curl \
  -d '{"surname":"Popper"}' \
  -H "Content-Type: application/json" \
  -X PATCH https://your-domain.com/api/v1/users/1
json
{
  "id": 1,
  "name": "John",
  "surname": "Popper"
}

Delete ​

You can use the following example to delete a record.

ts
const response = await api.resource("users/1").delete();
bash
$ curl \
  -H "Content-Type: application/json" \
  -X DELETE https://your-domain.com/api/v1/users/1
json
// empty-response

Find ​

You can get a single record by using the find function.

ts
const user = await api.find("users/1");
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users/1
json
{
  "id": 1,
  "name": "...",
  "created_at": "2021-10-21 00:00:00",
  "updated_at": "2021-10-21 00:00:00"
}

Paginate ​

Axe API client library has advanced query features that work Axe API server perfectly.

For example, you can paginate items easily.

ts
const response = await api.resource("users").paginate();
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users?page=1&perPage=10
json
{
  "data": [
    {
      "id": 1,
      "name": "...",
      "surname": "...",
      "created_at": "2021-10-21 00:00:00",
      "updated_at": "2021-10-21 00:00:00"
    }
  ],
  "pagination": {
    "total": 1,
    "lastPage": 1,
    "perPage": 10,
    "currentPage": 1,
    "from": 0,
    "to": 1
  }
}

You can use page or perPage parameters to fetch the correct page.

ts
const response = await api.resource("users").paginate({ page: 10, perPage: 5 });
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users?page=10&perPage=5
json
{
  "data": [],
  "pagination": {
    "total": 0,
    "lastPage": 0,
    "perPage": 5,
    "currentPage": 10,
    "from": 0,
    "to": 5
  }
}

Fields ​

You can select which fields should be listed.

ts
const response = await api
  .resource("users")
  .fields("name", "surname")
  .paginate();
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users?page=1&perPage=10&fields=name,surname
json
{
  "data": [
    {
      "name": "...",
      "surname": "..."
    }
  ],
  "pagination": {
    "total": 1,
    "lastPage": 1,
    "perPage": 10,
    "currentPage": 1,
    "from": 0,
    "to": 1
  }
}

Sorting ​

You can sort the items by many fields.

ts
const response = await api
  .resource("users")
  .sort("name")
  .sort("surname", "DESC")
  .sort("id", "ASC")
  .paginate();
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users?page=1&perPage=10&sort=name,-surname,id
json
{
  "data": [
    {
      "id": 1,
      "name": "...",
      "created_at": "2021-10-21 00:00:00",
      "updated_at": "2021-10-21 00:00:00"
    }
  ],
  "pagination": {
    "total": 1,
    "lastPage": 1,
    "perPage": 10,
    "currentPage": 1,
    "from": 0,
    "to": 1
  }
}

Where ​

You can filter items by using where*() functions. There are many different functions that you can use.

Let's start with a simple condition;

ts
const response = await api.resource("users").where("age", 18).paginate();
SQL
SELECT * FROM users
WHERE `age` = 18;

You can add multiple conditions at the same time:

ts
const response = await api
  .resource("users")
  .where("age", ">=", 18)
  .where("name", "Karl")
  .paginate();
SQL
SELECT * FROM users
WHERE `age` >= 18 AND `name` = 'Karl';

You can specify the logical operators by using andWhere or orWhere functions.

ts
const response = await api
  .resource("users")
  .where("age", ">=", 18)
  .orWhere("name", "Karl")
  .andWhere("surname", "Popper")
  .paginate();
SQL
SELECT * FROM users
WHERE `age` >= 18 OR `name` = 'Karl' AND `surname` = 'Popper';

You can add multiple child conditions by passing the query function as a parameter.

ts
const response = await api
  .resource("users")
  .where((query) => {
    return query.where("name", "Karl").orWhere("surname", "Popper");
  })
  .where("age", ">=", 30)
  .paginate();
SQL
SELECT * FROM users
WHERE (`name` = 'Karl' OR `surname` = 'Popper') AND `age` >= 30;

You can fetch the related data.

ts
const response = await api.resource("users").with("role{title}").paginate();
bash
$ curl \
  -H "Content-Type: application/json" \
  -X GET https://your-domain.com/api/v1/users?page=1&perPage=10&with=role{title}
json
{
  "data": [
    {
      "id": 1,
      "name": "...",
      "role": {
        "title": "..."
      },
      "created_at": "2021-10-21 00:00:00",
      "updated_at": "2021-10-21 00:00:00"
    }
  ],
  "pagination": {
    "total": 1,
    "lastPage": 1,
    "perPage": 10,
    "currentPage": 1,
    "from": 0,
    "to": 1
  }
}
