    Leo-Logger

    Such an awesome logger that we had to break it out from the LEO SDK and make it its own project!

    Available methods

    • sub
    • info
    • json
    • time
    • timeEnd
    • log
    • debug
    • error
    • configure

    Available configuration options

    • a = all
    • t = time
    • i = info
    • d = debug
    • e = error
    • T = printTimestamp

    Usage example:

    export LEO_LOGGER='/.*/d'

    Working with namespaces

    You can log logs for specific namespaces by passing a string when requiring the leo-logger. Example:

    const logger = require('leo-logger')('my-special-namespace');

    When you use a namespace, logging works the same, but the output will be prefixed with the namespace:

    logger.log('My namespaced log');
    // outputs: my-special-namespace my namespaced log

    If you want to display logs for certain namespaces only, you can adjust LEO_LOGGER to match the namespace.

    # Example outputting all logs for my-special-namespace 
    export LEO_LOGGER='/my\-special\-namespace/a'

    You may notice in the previous example how it appears we’re using regex. This allows you to employ more powerful namespace logging. As an example, let’s say you have a shopping cart, and you want to have logs specific to the checkout process. Each of the checkout pages would include the leo-logger. I'm going to use an example of 2 checkout pages, which would look like this:

    const logger = require('leo-logger')('checkout-payment');
    const logger = require('leo-logger')('checkout-process-order');

    Then if you want to display logs for the process-order page, you would do this:

    export LEO_LOGGER='/checkout\-process\-order/a'

    But if you want to display logs for all checkout pages, you can use the power of regex to select everything starting with “checkout”:

    export LEO_LOGGER='/checkout.*/a'

    Loggers

    logger.log('my logged message');
    logger.info('my info');
    logger.debug('just some debugging code');
     

    Timers

    // start a timer
    logger.time('myTimer');
    // stop a timer
    logger.timeEnd('endTimer');
