    A terminal reporting utility with logging capabilities.


    Getting started

    To install @halokit/reporter in your project, you will need to run the following command using npm:

    npm install -S @halokit/reporter

    If you prefer yarn, use the following command instead:

    yarn add @halokit/reporter



    This module can be imported and used by doing the following in your code:

    // ES6 Module
    import { reporter, emojiReporter } from '@halokit/reporter';
    // CommonJS Module
    const { reporter, emojiReporter } = require('@halokit/reporter');

    All the modules have TypeScript type definitions built in. There is no need to install additional packages.

    Creating a logging item

    HaloKit's reporter relies on a specific object format that should have at least the following properties:

    var item = {
      content: 'Hello world!',
      level: 1 // 0 - 6

    If you are using typescript, you can use the interface LogItem to build objects, as defined here:

    interface LogItem {
      content: string;
      level: LogLevel;
      print?: boolean;

    The print property will determine whether the built log entry should be redirected to standard output aswell, and defaults to false.

    Where the available log levels are:

    export enum LogLevel {
      Log = 0,
      Debug = 1,
      Info = 2,
      Warn = 3,
      Error = 4,
      Fatal = 5,
      Success = 6

    You can use the enum name or it's integer representation.

    Logging the item

    Once you have your loggable item created, you can generate a log/reporting entry out of it by using the reporter of your choice.

    This package exports both a reporter and an emojiReporter. If you decide to use the emoji reporter, an emoji, representative of each level, with be added at the beginning of each logging entry.

    A working example would be as follows:

    import { reporter, emojiReporter } from '@halokit/reporter';
    const item = {
      content: 'Hello world!',
      level: 1
    const plainLog =; // debug: Hello world!
    const emojiLog =; // 🛠  debug: Hello world!

    Once you've called the report() method, another object will be returned with the following properties:

      content: string; // Built log .
      technical: string; // Plain log, without any emojis or coloring.
      raw: string; // Plain log with emojis, but no coloring.
      timestamp: string; // Time of creation of the log.


    We're always looking for contributors to help us fix bugs, build new features, or help us improve the project documentation.
