winston-dev-console

A [email protected] console format for development (based on winston-console-format) that aims to improve NodeJS development UX by

  • adding the source of the logging statement to the log output
  • optimizing readability of each log statement through log statement separation, output colorization and arg pretty printing

Demo

Real world screenshot:

Install

npm install winston @epegzz/winston-dev-console

or

yarn add winston @epegzz/winston-dev-console

Usage TypeScript

import { createLogger, format, transports } from "winston";
import winstonDevConsole from "@epegzz/winston-dev-console";
import util from "util";

let log = createLogger({
  level: "silly", // or use process.env.LOG_LEVEL
});

// Note: You probably only want to use winstonDevConsole during development
log = winstonDevConsole.init(log);
log.add(
  winstonDevConsole.transport({
    showTimestamps: false,
    addLineSeparation: true,
  })
);

log.silly("Logging initialized");
log.debug("Debug an object", { make: "Ford", model: "Mustang", year: 1969 });
log.verbose("Returned value", { value: util.format });
log.info("Information", {
  options: ["Lorem ipsum", "dolor sit amet"],
  values: ["Donec augue eros, ultrices."],
});
log.warn("Warning");
log.error(new Error("Unexpected error"));

Usage JavaScript

const { createLogger, format, transports } = require("winston");
const winstonDevConsole = require("@epegzz/winston-dev-console").default;
const util = require("util");

let log = createLogger({
  level: "silly", // or use process.env.LOG_LEVEL
});

// Note: You probably only want to use winstonDevConsole during development
log = winstonDevConsole.init(log);
log.add(
  winstonDevConsole.transport({
    showTimestamps: false,
    addLineSeparation: true,
  })
);

log.silly("Logging initialized");
log.debug("Debug an object", { make: "Ford", model: "Mustang", year: 1969 });
log.verbose("Returned value", { value: util.format });
log.info("Information", {
  options: ["Lorem ipsum", "dolor sit amet"],
  values: ["Donec augue eros, ultrices."],
});
log.warn("Warning");
log.error(new Error("Unexpected error"));

API

winstonDevConsole.format(options)

options

Configuration object.

Type: DevConsoleFormatOptions

options.inspectOptions

util.inspect() configuration object.

Type: Object

options.basePath

Used to remove the base path of the project when showing the file path of the log statement. By default anything in the path before (and including) the src folder will be removed.

Type: String

options.addLineSeparation

Wheather or not to separate each log statement with a blank line.
