Node.js errors Catcher module for Hawk.so

Initial params

Initialization params:

Usage

1. Create an account and get an Integration Token.
2. Add @hawk.so/nodejs package to your project.
3. Require and initialize module.

Install

Use NPM or Yarn to install Catcher @hawk.so/nodejs.

$ npm install @hawk.so/nodejs --save

$ yarn add @hawk.so/nodejs

Require HawkCatcher module

For CommonJS projects

const HawkCatcher = require('@hawk.so/nodejs').default;

For ESM projects

import HawkCatcher from '@hawk.so/nodejs';

Init HawkCatcher

Initialize HawkCatcher in the entry file of your project by passing a project token.

const HAWK_TOKEN = 'eyJhb...VPsc=';

HawkCatcher.init(HAWK_TOKEN);

HawkCatcher adds listeners for uncaughtException and unhandledRejection itself.

Disable global errors handling

If you don't want to initialize handlers for global exceptions then use disableGlobalErrorsHandling param.

HawkCatcher.init({
  token: HAWK_TOKEN,
  disableGlobalErrorsHandling: true,
});

Then you can catch events manually.

Global context

You can define global context for all event to be caught.

HawkCatcher.init({
  token: HAWK_TOKEN,
  context: {
    myOwnDebugInfo: '1234'
  }
});

Releases

To mark events to specific release pass the release identifier string to intial config.

HawkCatcher.init({
  token: 'INTEGRATION TOKEN',
  release: process.env.releaseId
})

Catch exceptions manually

After initializing you can catch exceptions manually in try-catch constructions in any project's place.

Just require HawkCatcher and call .send() method.

try {
  throw new Error('My lovely error');
} catch (e) {
  HawkCatcher.send(e);
}

If HawkCatcher was not initialized then .send() method will do nothing.

Event context

You can pass any information as context param for a single event.

try {
  throw new Error('User not found');
} catch (e) {
  HawkCatcher.send(e, {
    myOwnDebugInfo: '1234'
  });
}

This context object will be merged with global context if it exists.

User

You can send user data as a third param.

Available fields: | Param | Type | Is required | Description | | --- | --- | --- | --- | | id | string\|number | required | User's identifier | | name | string | - | User's name | | url | string | - | User's profile url | | image | string | - | User's profile pic url |

try {
  throw new Error('Cannot create a new post');
} catch (e) {
  HawkCatcher.send(e, {}, {
    id: 1234,
    name: 'Taly'
});
}

Sensitive data filtering

You can filter any data that you don't want to send to Hawk. Use the beforeSend() hook for that reason.

HawkCatcher.init({
  token: 'INTEGRATION TOKEN',
  beforeSend(event){
    if (event.user && event.user.name){
      delete event.user.name;
    }

    return event;
  }
})
