hawk.collector

Go Report Card

Powerful module that can handle most errors around the web.

Build and run

Install RabbitMQ manually and build Hawk.collector

make build
./bin/hawk.collector

Build for specific os

make build-linux
make build-windows
make build-darwin

or build all

make build-all

Import RabbitMQ definitions

rabbitmqadmin import config/rabbit.definitions.json

Run in Docker

make docker

Data flows

Request from errors catcher

The following structure represents data that go through the HTTP request (POST request to '/' with Content-Type: application/json)

name type description
token string (base64) JWT in base64 format
payload raw JSON Nested valid JSON
catcherType string Type of the catcher (errors/golang, errors/php)

JSON example

{
  "token": "...",
  "catcherType": "errors/golang",
  "payload": {
    "title": "Test exception",
    "timestamp": 1545203808
  }
}

Request to upload sourcemap

The following structure represents data got through the HTTP request (POST request to '/release' with Content-Type: multipart/form-data)

Form values

name type description
release string Release name
file multipart (optional) Content of the binary file
commits commitMessage (optional) Suspected commits

commitMessage has the following format:

name type description
hash string Commit hash
title string Commit description
author string Commit author
date string Commit date

Authentication is made via bearer token.

cURL sending example

curl --request POST \
 -F 'release=1.0.1'\
 -F 'commits=[{"hash":"557940a440352d9d86ad5610f2e366aafb2729e4","title":"Add some stuff","author":"[email protected]","date":"Wed May 6 13:37:00 2021 +0300"}]'\
 -F "repository=https://github.com/codex-team/hawk.api.nodejs"\
 -F file=@"main.min.js.map"\
 -H "Authorization: Bearer TOKEN" https://test.stage-k1.hawk.so/release

Response message

HTTP response from the collector. It is provided as JSON with HTTP status code.

name type description
code int internal error code
error bool if the error was occurred
message string result details

For now there are two possible HTTP status codes: 200 (OK) and 400 (Bad request).

Examples

{"error": true, "message": "Token is empty", "code": 200}

{"error": true, "message": "Invalid JSON format", "code": 400}

No body will be returned for the valid response (200).

Websocket transport

Errors can be sent via websockets (for example with the help of wscat util).

~# wscat -c wss://test.stage-k1.hawk.so/ws                                                                                                                                                                                                              ✔  11720  20:53:23
connected (press CTRL+C to quit)
> f
< {"code":400,"error":true,"message":"Invalid JSON format"}
> {"token": "...","catcherType": "errors/golang","payload": {"title": "Test exception","timestamp": 1545203808}}
< {"code":200,"error":false,"message":"OK"}

Message broker

For now we support RabbitMQ as a general AMQP broker. We declare a durable exchange with errors name. The valid payload JSON from Request structure goes directly to the exchange with the route specified by catcherType value.

Environment variables

Basic configuration is taken from .env file.

variable example value description
BROKER_URL amqp://guest:guest@localhost:5672/ Connection URI to RabbitMQ
EXCHANGE errors Basic exchange for errors
RELEASE_EXCHANGE release Basic exchange for releases
