    Using yarn:

    yarn add consola

    Using npm:

    npm i consola

    Getting Started

    const consola = require('consola')
    // See types section for all available types
    consola.success('Built!')'Reporter: Some info')
    consola.error(new Error('Foo'))

    Will display in the terminal:

    NOTE: Alternatively, you can import consola from source. But don't forget to whitelist it for transpilation:

    import consola from 'consola/src/node'
    import consola from 'consola/src/browser'


    <type>(logObject) <type>(args...)

    Log to all reporters.


    A list of available types can be found here.


    • Aliases: add

    Register a custom reporter instance.


    • Aliases: remove, clear

    Remove a registered reporter.

    If no arguments are passed all reporters will be removed.


    Replace all reporters.


    Create a new Consola instance and inherit all parent options for defaults.


    Create a new Consola instance with provided defaults


    • Aliases: withScope

    Create a new Consola instance with that tag.

    wrapConsole() restoreConsole()

    Globally redirect all console.log, etc calls to consola handlers.

    wrapStd() restoreStd()

    Globally redirect all stdout/stderr outputs to consola.

    wrapAll() restoreAll()

    Wrap both, std and console.

    console uses std in the underlying so calling wrapStd redirects console too. Benefit of this function is that things like will be correctly redirected to the corresponding type.

    pauseLogs() resumeLogs()

    • Aliases: pause/resume

    Globally pause and resume logs.

    Consola will enqueue all logs when paused and then sends them to the reported when resumed.


    • Aliases: mock

    Mock all types. Useful for using with tests.

    The first argument passed to mockTypes should be a callback function accepting (typeName, type) and returning the mocked value:

    consola.mockTypes((typeName, type) => jest.fn())

    Please note that with the example above, everything is mocked independently for each type. If you need one mocked fn create it outside:

    const fn = jest.fn()
    consola.mockTypes(() => fn)

    If callback function returns a falsy value, that type won't be mocked.

    For example if you just need to mock consola.fatal:

    consola.mockTypes((typeName) => typeName === 'fatal' && jest.fn())

    NOTE: Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without need to extra efforts.



    An array of active reporters.


    The level to display logs. Any logs at or above this level will be displayed. List of available levels here.

    You can set the log level using the CONSOLA_LEVEL environment variable, which must have the numeric log level as its value.


    The logObject is a free-to-extend object which will be passed to reporters.

    Standard fields:

    • message
    • additional
    • args
    • date
    • tag

    Extra fields:

    • badge


    Choose between one of the built-in reporters or bring in your own one.

    By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs.

    Available reporters:

    Creating your own reporter

    A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look into the linked implementations above.


    Types are used to actually log messages to the reporters. Each type is attached to a logging level.

    A list of all available default types is here.

    Creating a new instance

    Consola has a global instance and is recommended to use everywhere. In case more control is needed, create a new instance.

    import consola from 'consola'
    const logger = consola.create({
        // level: 4,
        reporters: [
          new consola.JSONReporter()
        defaults: {
          additionalColor: 'white'


    With jest

    describe('your-consola-mock-test', () => {
      beforeAll(() => {
          // Redirect std and console to consola too
          // Calling this once is sufficient
        beforeEach(() => {
          // Re-mock consola before each test call to remove
          // calls from before
          consola.mockTypes(() => jest.fn())
      test('your test', async () => {
        // Some code here
        // Let's retrieve all messages of `consola.log`
        // Get the mock and map all calls to their first argument
        const consolaMessages = => c[0])
        expect(consolaMessages).toContain('your message')

    With jsdom

      virtualConsole: new jsdom.VirtualConsole().sendTo(consola)
