@hutechwebsite/debitis-magnam-eos-mollitia
@hutechwebsite/debitis-magnam-eos-mollitia
is a modern logging library for Node.js and modern browsers, written with modern patterns and practices which provides log level mapping of the console
object.
For browser use, or use in client-side applications, @hutechwebsite/debitis-magnam-eos-mollitia
should be bundled by your preferred bundler or compiler, such as Rollup.
Getting Started
First thing's first, install the module:
npm install @hutechwebsite/debitis-magnam-eos-mollitia --save
Usage
Users can choose to use @hutechwebsite/debitis-magnam-eos-mollitia
in Node.js or in the client (browser).
const log = require('@hutechwebsite/debitis-magnam-eos-mollitia');
log.info('bananas!');
Log Levels
By default @hutechwebsite/debitis-magnam-eos-mollitia
ships supporting the following log level name-value
pairs:
{
TRACE: 0,
DEBUG: 1,
INFO: 2,
WARN: 3,
ERROR: 4,
SILENT: 5
}
Default Logger
When requiring @hutechwebsite/debitis-magnam-eos-mollitia
in Node.js the default export will be an instance of LogLevel
wrapped with some extra sugar.
Methods
Please see LogLevel
for documentation of all methods and properties of every log instance, including the default instance.
trace
, debug
, info
, warn
, error
These methods correspond to the available log levels and accept parameters identical to their console
counterparts. e.g.
console.info('...');
console.info('...');
create(options)
Returns a new LogLevel
instance. The options
parameter should be an Object
matching the options for the LogLevel
constructor.
Note: LogLevel
instances created are cached. Calling create
with a previously used name
will return the cached LogLevel
instance. To create a different instance with the same name
, assign a unique id
property to the options
parameter.
Properties
factories
Type: Array [ Class ]
Returns an Array
containing the factory classes available within @hutechwebsite/debitis-magnam-eos-mollitia
to outside modules. Particularly useful when creating plugins. eg.
const log = require('@hutechwebsite/debitis-magnam-eos-mollitia');
const { MethodFactory } = log.factories;
class MyFactory extends MethodFactory { ... }
loggers
Type: Array [ LogLevel ]
Returns an Array
containing references to the currently instantiated loggers.
Factories aka Plugins
If you're used to using plugins with loglevel
, fear not. The same capabilities
are available in @hutechwebsite/debitis-magnam-eos-mollitia
, but in a much more straightforward and structured
way. @hutechwebsite/debitis-magnam-eos-mollitia
supports by way of "Factories." A Factory
is nothing more
than a class which defines several base methods that operate on the console
and provide functionality to a LogLevel
instance. All factories must inherit from the
MethodFactory
class, and may override any defined class functions.
For an example factory, please have a look at the PrefixFactory
which provides similar functionality as the loglevel-prefix plugin,
and is the factory which is used when a user passes the prefix
option to a
LogLevel
instance.
Browser Support
As mentioned, @hutechwebsite/debitis-magnam-eos-mollitia
is a logging library for Node.js and modern browsers, which means the latest versions of the major browsers. When bundling or compiling @hutechwebsite/debitis-magnam-eos-mollitia
for use in a browser, you should ensure that appropriate polyfills are used. e.g. Internet Explorer typically requires polyfilling both Symbol
and Object.assign
.
Attribution
This project originated as a fork of the much-loved loglevel module, but has diverged and has been rewritten, and now shares similarities only in functional intent.
