Collect Node.js Logs using Atatus Winston Logger

Winston is one of the most widely used logging libraries in Node.js applications. It’s designed to provide a highly customizable logging experience by separating concerns like log levels, formatting styles, and output destinations. atatus-winston is a winston plugin. With atatus-winston, you can take advantage of the winston logger framework with your Node.js app.

Add the dependency to your project

npm install atatus-winston --save

Configure atatus-winston

Use the samples in the code block below as a starting point, and replace the sample with a configuration that matches your needs.

const winston = require('winston');
const AtatusWinstonTransport = require('atatus-winston');

let atatusWinstonTransport = new AtatusWinstonTransport({
    apiKey: '<YOUR_API_KEY>',
    name: 'atatus-winston',
    service: 'payment-service',         // TODO: Update this to your actual service name
    source: 'payment-service'           // TODO: Update this to your actual service name
});

const logger = winston.createLogger({
    format: winston.format.simple(),
    transports: [ atatusWinstonTransport ],
});

logger.info('Just a test message for Atatus Winston Logger setup');

Replace <YOUR_API_KEY> with your own Atatus api key.

Disable console logs

The winston logger by default sends all logs to the console. You can easily disable this by adding this line to your code :

winston.remove(winston.transports.Console);

Running with Typescript

If you don’t have a ‘tsconfig.json’ file start by running:

tsc --init

On your ‘tsconfig’ file, under ‘compilerOptions’ make sure you have ‘esModuleInterop’ flag with the value ‘true’ or add it this way:

  "compilerOptions": {
    ...
    "esModuleInterop": true
  }

Code sample:

import winston from 'winston';
import AtatusWinstonTransport from 'atatus-winston';

let atatusWinstonTransport = new AtatusWinstonTransport({
    apiKey: '<YOUR_API_KEY>',
    name: 'atatus-winston',
    service: 'payment-service',     // TODO: Update this to your actual service name
    source: 'payment-service'       // TODO: Update this to your actual service name
});

const logger = winston.createLogger({
    format: winston.format.simple(),
    transports: [ atatusWinstonTransport ],
});

logger.log('warn', 'Just a test warning message');

Replace <YOUR_API_KEY> with your own Atatus api key.

Troubleshooting

To fix errors related to “esModuleInterop” flag make sure you run the relevant ‘tsconfig’ file. These might help:

tsc <file-name>.ts --esModuleInterop

tsc --project tsconfig.json
