Usage

1. Wrapping an HTTP Request

Use the wrapperHttp function to intercept an HTTP request, collect metrics, and optionally send them to the Brick Traces API.

Example with Axios:

import axios from "axios";
import { wrapperHttp } from "brick-traces";

(async () => {
  const response = await wrapperHttp(
    axios.get("https://jsonplaceholder.typicode.com/posts/1"),
    {
      accessKey: "your-brick-access-key",
      secret: "your-brick-secret",
      clientId: "your-client-id",
      document: "111.111.111-11",
      name: "Fetch Post",
      tags: ["example", "axios"],
      metadata: { purpose: "testing" },
      cost: 10,
      provider: "example-provider",
    }
  );

  console.log("Response:", response);
})();

Configuration Options:

• clientId (string): Identifier for the client making the request.
• accessKey (string, optional): Your Brick Traces access key.
• secret (string, optional): Your Brick Traces secret.
• name (string, optional): A name for the trace.
• document (string, optional): A unique identifier for the trace.
• tags (array, optional): Tags associated with the trace.
• metadata (object, optional): Additional metadata for the request.
• cost (number, optional): The cost of the operation.
• providerInternalId (string, optional): The provider's internal identifier.
• provider (string, optional): The name of the provider.

2. Environment Variable

Set the BRICK_TRACES_ACCESS_KEY and the BRICK_TRACES_SECRET to authenticate and start collecting metrics.

Example .env file:

BRICK_TRACES_ACCESS_KEY=<YOUR_ACCESS_KEY>
BRICK_TRACES_SECRET=<YOUR_SECRET>

---

3. Sending Data to Brick Traces

When using the wrapperHttp function with an accessKey and secret, the following data is sent asynchronously to the Brick Traces API:

Trace Data:

{
  "accessKey": "your-brick-access-key",
  "secret": "your-brick-secret",
  "trace": {
    "tags": ["example", "axios"],
    "clientId": "your-client-id",
    "document": "111.111.111-11",
    "name": "Fetch Post"
  },
  "request": {
    "metadata": { "purpose": "testing" },
    "requestedAt": "2025-01-12T12:00:00.000Z",
    "cost": 10,
    "provider": "example-provider",
    "elapsedTime": 123,
    "providerInternalId": "internal-id",
    "statusCode": 200,
    "responseBody": "{\"id\": 1, \"title\": \"Post Title\"}"
  },
  "timestamp": "2025-01-12T12:00:01.000Z"
}

---

4. Decisions

The decide function allows you to log and send decisions based on evaluation criteria to the Brick Traces API.

Example:

import { decide } from "brick-traces";

const decision = {
  decisionId: "133f0236-44b9-4a50-8aa5-488d6097fce9",
};

const searchParams = {
  clientId: "12345",
  document: "67890",
};

decide(decision, searchParams, { accessKey: "your-access-key", secret: "your-credential-secret" });

Function Details:

• decision: Object containing the decision details (e.g., outcome and reason).
  • decisionId (string, optional): Referes to a decision already registered at Brick's platform.
  • name (string, optional): If decisionId is empty, you can pass your own name of the decision.
  • variant (string, optional): If name exists, you must send a variant that can be one of ['APPROVAL', 'REFUSAL', 'MANUAL'].
• searchParams: Object containing search identifiers (e.g., clientId, document).
• config: Object with optional parameters to authenticate the request.

This data is sent to the /decision endpoint of the Brick Traces API.

5. Registering Variables

The registerVariables function allows you to send contextual variables for a specific search to the Brick Traces API.

Example:

import { registerVariables } from "brick-traces";

const variables = [
  { name: "transaction_amount", value: 150.75 },
  { name: "user_country", value: "US" },
];

const searchParams = {
  clientId: "12345",
  document: "67890",
};

registerVariables(variables, searchParams, { apiKey: "your-brick-api-key" });

Function Details:

• variables: Array of name-value pairs to register.
• searchParams: Object containing search identifiers.
• config: Object with optional apiKey to authenticate the request.

This data is sent to the /variable endpoint of the Brick Traces API.

---

Error Handling

Even if the request fails, brick-traces collects error details and sends them to the Brick Traces API.

Example:

try {
  await wrapperHttp(
    axios.get("https://jsonplaceholder.typicode.com/posts/invalid"),
    {
      accessKey: "your-access-key",
      secret: "your-credential-secret",
      clientId: "your-client-id",
      name: "Fetch Invalid Post",
    }
  );
} catch (error) {
  console.error("Request failed:", error);
}

Error payload:

{
  "statusCode": 404,
  "responseBody": "{\"error\": \"Not Found\"}"
}
