@pexxi/winston-azure-functions v0.1.0

winston-azure-functions

This is a fork of https://github.com/upcompass/winston-azure-functions with TypeScript build errors fixed.

Basically, this transport pipes all output to Azure Functions' context.log().

How to use

Setup

Install with npm:

npm install --save @pexxi/winston-azure-functions

or with Yarn:

yarn add @pexxi/winston-azure-functions

Usage

Create a logger component, where you can configure Winston:

import { Context } from "@azure/functions";
import { AzureFunctions } from "winston-azure-functions";
import winston = require("winston");

export const configure = (context: Context) => {
  winston.configure({
    transports: [new AzureFunctions({ context })],
  });
};

export default winston;

In your function, call configure first passing function context as parameter:

import { Context } from '@azure/functions'
import logger, { configureLogger } from "../src/utils/logger";
...
module.exports = function(context: Context) {
  configureLogger(context)
  // rest of the function code...
  logger.info("Logging some stuff...")
};

Now you can use it in the rest of your code, e.g.:

import logger from "./logger"

...

logger.info("Logging on info level...")

Just remember to configure your logger in each function before using it anywhere else during the execution.
